Food for Thought

The devastating effects of diabetes on Indigenous health in Australia.  
“It has become obvious that the situation is urgent and is an area of national neglect” says Dr Neale Cohen, General Manager Diabetes Services, BakerIDI Heart and Diabetes Institute. Diabetes rates in Australia are high but its prevalence in the Indigenous population is between three and four times higher than the rest of the population. There are many reasons, including genetics, poverty and lack of education and resources, particularly in remote communities. Dr Cohen says we need to act decisively. And now.

“In the past few years I have been fortunate enough to be involved in a clinical diabetes services in outreach communities in the Northern Territory, says Dr Cohen. “As an Australian and experienced physician, I am shocked and alarmed. It has become obvious that the situation is urgent and is an area of national neglect. There’s a tsunami of kidney failure and other complications heading our way with many people having signs of early kidney damage, eye damage and heart disease. All these are associated with very poor control of their diabetes. Complication rates in the indigenous population are among the highest in the world and about 10 times non-indigenous rates.

In my travels to remote settlements, I have seen children as young as 12 with type 2 diabetes. More worrying is the age of patients developing early kidney complications. I know of one young man aged 16 who already has signs of significant kidney disease and will no doubt head towards dialysis and death in the next 10 to 15 years. Many of my patients continuously live with blood glucose levels in the 20 to 30 range (compared to a normal range of 4 to 6).

There are many challenges in managing Indigenous diabetes. Its nature appears to be more aggressive and less responsive to conventional therapies. We have now reached a crisis point for the devastating effects of diabetes on Indigenous health. And while treatment of chronic disease in remote communities is challenging and complex, we must not be deterred. The loss of a great Australian, M. Yunupingu, should serve as a reminder that more needs to be done. Tiny clinics in remote towns need staff devoted to the prevention and treatment of diabetes and its complications. And communities need assistance at every level with the day-to-day management of this very complex disease.

Education and health promotion are critical in the long term but their health benefits may take decades. Clearly, we don’t have that sort of time. An emphatic response, firmly grounded in equity, compassion and human rights is needed to turn the tide of what will soon become a national disaster. If we do not act decisively, we will look back in 10 years and wonder why we didn’t.”

Where soft drink is cheaper than water. Short films deliver health messages in remote Indigenous communities. Skinnyfish, a Darwin-based record company, is using its connections with Indigenous musicians to spread health messages in remote communities. Co-founder Mark Grose says they will launch 30 short films devised and written by people from seven communities from Western Arnhem Land to Croker Island (with help from the record label and filmmaker Paul Williams). Comedy, music and traditional knowledge are used to tackle serious health issues, including excess consumption of soft drinks. “So it’s really Aboriginal people speaking to Aboriginal people about a modern issue.” The overall message is “get active, eat bush tucker and live longer”. Nigel Yunupingu stars in Sugar Man, which addresses excess sugar consumption in his community of Galiwin’ku on Elcho Island, off the coast of Arnhem Land. WATCH.

News and Reviews

Soft drinks: making the healthy choice the cheaper choice. 
Prof. Jack Winkler and his co-authors suggest a new strategy for healthy living in The Grocer which sets out the economics (costs of production, margins and profits) that show it is possible to sell healthier versions of mass market foods and beverages at lower prices than the standard high refined sugar/starch, high calorie products.

Diet soft drinks

Using soft drinks as their example, they demonstrate the feasibility of combining product reformulation by food and beverage companies with economic incentives for consumers. The writers believe that their model is applicable in developed countries as many of the products eaten are processed foods, most could be nutritionally improved, and many healthier alternatives could be made and sold more cheaply. We would like to see low GI options included in reformulating products to help people not only manage energy intake, but manage their blood glucose levels, too. 

Bush tucker data.
#1 Tables of composition of Australian Aboriginal foods In her first job as a lecturer at the University of Sydney, Professor Jennie Brand-Miller analysed the nutrient composition of Aboriginal bush foods. “We looked at the protein, carbohydrate, fat and fibre content and built a database of the Indigenous diet,” she says. She also found that many of the foods tended to be low GI and this led her to question the role of food in human evolution and the prevalence of conditions such as type 2 diabetes.

Tables of composition of Australian Aboriginal foods

#2 Indigenous foods added to Nutrition Panel Calculator Food Standards Australia New Zealand has added 14 new Indigenous foods to the NPC: lemon myrtle, bush tomato, Kakadu plum, finger lime, desert lime, lemon aspen fruit juice, satinash fruit. They have also added the following herbs and spices: anise myrtle leaf, native pepper (dried leaves and berries), saltbush, river mint, sea parsley, and olida.

Cook books – a recipe for girth expansion? 
Most people believe that the food they prepare themselves is healthier than commercially prepared food. While this might be right when you consider the immeasurable love we add, it’s not necessarily the case when we take a cold hard look at the numbers. While surveys tell us we are eating out more and more, the bulk of the diet for families is still consumed from home so the way we cook is important. Way back in 2005, Prof. Brian Wansink conducted a survey that found that nutritional gatekeepers (the person responsible for acquiring and preparing meals within a household) controlled 72% of a household’s dietary intake.

If recipes in cookbooks are anything to go by, many well-intentioned gatekeepers could be feeding their families more than they thought. A 2013 study in the Scandinavian Journal of Public Health reports that portion sizes measured in calories in classical Danish recipes have increased significantly in the past 100 years, especially for meat, starchy foods and sauces. This is in line with Wansink’s 2009 study that found average calories per serving jumped 63% in 70 years in 17 of the 18 recipes through seven editions of the ‘classic’ The Joy of Cooking since it was first published in 1936 until the 2006 update.

And there’s more. In 2012 a study in the BMJ found that TV chef recipes from five best-selling cookbooks (30 Minute Meals by Jamie Oliver, Baking Made Easy by Lorraine Pascale, Ministry of Food by Jamie Oliver, Kitchen by Nigella Lawson, and River Cottage Everyday by Hugh Fearnley-Whittingstall) contained significantly more energy per portion (about 100 calories more) than ready meals from Asda, Sainsbury's and Tesco – notably more protein, fat, and saturated fat per portion and less fibre. If you are the nutritional gatekeeper, there’s no need to say no to deliciously tempting chef recipes in gorgeously glossy cook books, they can be a great way to bring more flavour, variety and enjoyment to family dinners. But be mindful and take our waist-saving tips.

Tip 1: Do the numbers. You may need to cut back quantities. Here is a guide to average per person servings (remembering teenage boys and big muscled blokes are not average!).

  • Meat and chicken (raw and lean) – allow about 150 grams (5 ounces) per person
  • Fish fillets (fresh) – allow 150–200 grams (5–7 ounces) per person
  • Pasta (dried pieces) – allow 60–80 grams (about 2–3 ounces) per person
  • Rice (uncooked) – allow ¼ cup per person
  • Potatoes – allow 2–3 small new potatoes or 1 medium–large potato per person  
Tip 2: Renovate their recipes. You may need to cut back the salt, cut back the fat and double the veggies.
Tip 3: Check out the nutritional analysis if there is one. We have to say thumbs up to Laura Parr (and to Jamie) for the easy-to-understand nutritional analysis in Jamie’s 15-Minute Meals.

We need to practice portion caution at home as well as away and keep in mind that celebrity chefs aren't always the best role models when it comes to healthy, everyday family meals.

Nicole's Taste of Health

Donta be lasta for pasta
Pasta generates such varied responses nowadays. I’m not sure how this humble food went from a much-loved traditional staple to eliciting fear and loathing for its carb content, but such is our whacky, affluent Western, diet-obsessed world. The origin of pasta is an age-old argument between the Chinese and the Italians, but noodles and pasta are both simple recipes of flour, water and perhaps a little egg. It was the type of wheat used, accompaniments, that spliced the gastronomic evolutionary tree into divergent directions. The best pasta is made from especially hard durum wheat and Australia grows some of the best in the world.

The exact origins of pasta are just academic now because Italian cuisine and pasta have travelled the world and made themselves at home everywhere. To an Italian, the love of pasta is almost encoded in their DNA and symbolic of family, culture and the enjoyment of food and life. It would not be unusual in an Italian household to eat pasta every day of the week and never tire of it because there are so many shapes and sauces: Monday night spaghetti with pesto sauce; Tuesday night penne with creamy mushroom sauce; Wednesday night cannelloni stuffed with ricotta and spinach; Thursday night Rigatoni with tuna and capers, and Friday night lasagne with Napolitano sauce. Just writing these dishes is enough to make me salivate!

There are hundreds of shapes or ‘cuts’ of pasta which Italians categorise into two main groups: short cuts like penne, and long cuts like spaghetti. Many have delightful Italian names describing their shape, like linguini (little tongues); vermicelli (worms); spaghetti (little strings), capellini (thin hair); fusilli (long rifles); orechiette (little ears); Fettuccine (little slices); penne (quill); spiralli (spiral); conchiglie (shell); farfalle (butterflies) and risoni (rice). There are also pasta shapes that can be filled such as cannelloni, ravioli and lasagne and are a class of their own.

The versatility of pasta is further enhanced because you can serve it hold or cold with lunch or dinner and it goes with just about anything. I always cook more pasta than I need for one meal so I can whip up a salad the next day and turn it into something different. Another super time-saving tip is you can cook up a load and freeze it into meal size portions for those days when you don’t even have the 15 minutes needed to cook dry pasta. And of course these days you can even buy fresh pasta that takes very little time to reheat. Importantly, pasta is affordable and convenient. The typical dried form can be stored in the cupboard for long periods to form the basis of a quick meal in a hurry.

Pasta is a carbohydrate food that provides energy to the brain and muscles but it is low GI when cooked al dente so it releases its energy more gradually and is gentler on blood glucose levels. A one-cup serving of plain pasta is low in salt (but watch out for the sauces), contains 9g protein, 43g carbohydrate and 3g fibre, and is high in the B vitamins thiamine and folate, and the mineral manganese.

Wholegrain (wholemeal) pasta is increasingly available as the world catches on to the health benefits of eating all the good bits of the grain (bran and germ) rather than just the starchy part. Sure, traditional Italian pasta is not wholegrain but why not utilise the even healthier version? We’ve got more dietary downsides to make up for than traditional Italian cuisine! The taste (and texture) varies by brand so try a few wholegrain pastas until you find one you like.

Contrary to popular mythology, pasta is not especially fattening, however attention to the sauce recipe and portion size will help reduce kilojoule (calorie) overload. While Italian peasant farmers could get away with huge bowls of the stuff to fuel their physical labours, most of us need to cut the portion down and balance it out with vegetables (or salad) and some lean meat, chicken, fish, egg or legumes (pulses) to suit our high-tech habits. While creamy sauces with bacon and four cheeses do taste delightful they don’t sit well with our office jobs, widening waistlines and creeping cholesterol levels and blood pressure, so choose lighter tomato-based sauces or a simple pesto. Of course a truly authentic pasta meal must be enjoyed with gusto: passionate discussion, noisy slurping, lots of hand gestures and nice glass of red.

Buon appetito!

Vegetable and pasta frittatas 
These individual frittatas are dead simple and super quick to make – perfect for lunch boxes either for lunch or as a substantial snack that is packed with energy and goodness. Try different combinations of favourite vegetables (corn, capsicum and pumpkin all work well) and throw in a can of drained and flaked salmon or tuna to boost the protein. Makes 12.

130g (4 1/2 oz) small short pasta, such as macaroni
Olive oil, to grease
2 medium zucchini (about 270g/9oz), coarsely grated
1 medium carrot (about 120g/4oz), coarsely grated
1 cup coarsely grated reduced fat extra tasty or vintage cheddar cheese
8 eggs
1/3 cup milk
Freshly ground black pepper and salt, to taste
120g/4oz small cherry or grape tomatoes, halved

Vegetable and pasta frittatas 

Preheat the oven to 180°C/350°F. Brush a 12-hole medium (80ml /1/3 cup) muffin tray with the oil to lightly grease.
Cook the pasta in plenty of boiling water, following the packet directions, until al dente. Drain and rinse under cold running water. Drain well.
Put the drained pasta, zucchini, carrot and 3/4 cup of the cheddar in a large bowl and mix to combine well. Divide the mixture evenly among the greased muffin tin holes.
Use a fork to whisk together the eggs and milk in a large jug until well combined. Season to taste with pepper and salt and whisk again. Pour evenly over the vegetable mixture. Press the halved tomatoes, cut side up, into the tops of the frittatas and then sprinkle with the remaining cheese.
Bake in preheated oven for 18-20 minutes or until just cooked through and lightly golden. Stand in the tin for a few minutes before running a palette knife around the outside of each frittata and lifting out. Serve warm or at room temperature.

Baker's tips
These frittatas will keep in an airtight container in the fridge for up to 2 days.

Polenta with buckwheat and mushrooms 
My husband, Sergio, grew up in the small northern Italian city of Reggio Emilia. His family had the custom of eating polenta every time it snowed. All were happy on polenta days, not only because his mother made this peasant food taste like a feast for kings, but also because the lengthy cooking time (40-plus minutes) provided extra heat in the house. He tells the story of his blind grandmother, who lived with them, who knew when it was snowing by how warm she felt sitting in her chair in the kitchen.

Polenta is as versatile as pasta or rice. Here I have added some buckwheat flour to lower this form of corn’s moderately high GI value. You can top with sausage or ragu, cheese or any combination of vegetables and herbs. Pick your favorite flavors and pile them on top of some steaming polenta. My guess is you won’t want to wait for the snow to return to try it again! This recipe probably has a moderate GI value. Servings: 8 or 16 (as a side).

2 cups dry coarse polenta
1 cup organic buckwheat flour
1oz (30g) dried porcini mushrooms
10oz (300g) mixed fresh mushrooms (crimini, white, baby portabella)
2 tbsp (30ml) extra virgin olive oil
2 large shallots (4 oz/120 g), thinly sliced
5 fresh sprigs thyme
Salt & pepper to taste
2oz (60g) Gruyere cheese

Polenta with buckwheat and mushrooms

Bring 8 cups of water to a boil. As that is happening mix the polenta and buckwheat flour in a medium bowl. Stir in 2 cups warm water and mix thoroughly. When the water is boiling, add salt if you wish and the polenta mixture. Stir, cover and simmer very slowly for about 30–40 minutes, stirring every 3–4 minutes to prevent the bottom from sticking. The polenta will become thick and creamy as it cooks. In the meantime, place the porcini in a small bowl and cover them with 2 cups warm water. Set aside.
Wash, pat dry and coarsely chop the fresh mushrooms. Set aside. In a large pan, heat the oil and add the shallots and sauté them on a medium-low flame until translucent (about 8 minutes).
Drain, rinse and pat dry the porcini, coarsely chop. Add to the mushroom mixture in the pan, sauté for 5 minutes. Add the thyme and cook for another 2 minutes. Add salt and pepper. Set aside.
When the polenta is done, remove it from the heat. Pour half the amount in the pot onto a wooden board, pat into a round mound. Add the mushroom mixture (warmed) on top of the mound, then cover with the remaining polenta. Sprinkle on the cheese. Serve immediately.

Honey Grilled Figs with Ricotta Dolce.  
 A fig halved and served with a dollop of yogurt makes a delicious end to a meal. If you want to go a step further, try this deliciously simple dessert from The Low GI Vegetarian Cookbook. For a very special occasion, add 2 teaspoons of amaretto (almond liqueur) or Frangelico to the ricotta mix. Serves 4

4 large ripe figs
4 tsp single source honey
200g (7oz) low fat ricotta
¼ cup carob or dark chocolate buttons, finely chopped
1 glace peach, finely chopped
1 tbsp icing sugar, sifted (LoGiCane is low GI)

Honey Grilled Figs with Ricotta Dolce

Cut each fig in half, place the figs on an ovenproof tray, cut side up and drizzle half a teaspoon of honey over each fig. Combine the ricotta, carob, glace peach, icing sugar and Amaretto in a medium size bowl, stir until well combined.
Preheat grill to high. Place fig halves under hot grill and grill for 2–3 minutes or until slightly caramelized. To serve, place 2 halves on each of 4 serving plates and top with a spoon of the ricotta dolce.

Putting the Fun Back into Fitness

Breathe easy when swimming – it makes a difference.   
When summer approaches, my heart lifts. I can get back in the water. And although it takes a little time for the Pacific Ocean to bring in the warmer currents, they are on their way. My current challenge is to improve my swimming technique to the point that I am strong and confident enough to “swim the bay” – jumping into Bondi Beach at the north end and swimming the 800 or so metres across to the south (think of it as beginner’s ocean swimming).

Before attempting the bay swim, you are advised to be able to comfortably swim the distance non-stop in a pool. And at the beginning of this season I couldn’t, not doing the crawl (freestyle). I have always been a breast stroker. It feels natural, streamlined and effortless. With freestyle I have always felt more like a flailing cat. So I enlisted the help of Mermaid Swimming Academy at Bondi, and into the paddling pool I was put.

Icebergs

My instructor started on my breathing. It all starts with the breath she said. And through a simple drill of lifting my face to the side, ear in line with water and then turning it back underneath without altering my neck alignment, I realised how right she was. I had a strange feeling like I was a child again, panicking at putting my head under water. This is always the way when you have practised something with poor technique for years, developing certain “bad habits”. The correct technique feels foreign, frustrating and indeed scary – as though you will never get it right. The beauty of technique training is that you do, and often so much more quickly than you imagine. But it takes perseverance.

After a week of getting in the pool and making my way slowly and often uncomfortably up and down the lanes, practising this new breathing technique on both sides, everything became easier, enjoyable even until I was relaxed and found 800 metres perfectly manageable. So now the bay awaits ...

Swimming is possibly my favourite form of exercise. The whole body is engaged and gets a great work-out against the resistance of the water. There is zero impact on the body, so a very good way to get fit without stressing your joints. It also keeps the heart rate up, builds endurance, tones muscle strength and helps maintain a healthy weight, while focussing on correct breathing, keeps both your mind and body active – like active meditation.

If you are not a comfortable swimmer and get puffed or anxious about swallowing water, I cannot recommend a few technique lessons highly enough. It will transform your relationship with swimming and open up a whole new world of physical possibility including ocean swimming.

Follow up:  You will remember back in January, that I was heading off to Hawaii to paddle in its glorious waters and waves. I spent a week with Dylan Thomas of Surfski Kauai, learning technique on different surf skis and getting comfortable paddling on the river and in the open ocean. Here is a clip of my first down wind "joyride" in a double Fenn ski behind instructor, Dylan.

The low down on dietary fibre
We hear lots about dietary fibre these days – in particular how good it is for us and how we all need to eat more. In this first of a two-part series, I explore what it is, why we think it is good for us, and why most of us need to eat more.

What fibre actually is The current definition of dietary fibre is much the same around the globe. Australia and New Zealand’s food regulator FSANZ says: “dietary fibre means that fraction of the edible part of plants or their extracts, or synthetic analogues that are resistant to the digestion and absorption in the small intestine, usually with complete or partial fermentation in the large intestine … and includes polysaccharides, oligosaccharides and lignins.” This basically means that dietary fibres come mostly (but not exclusively) from plants and that they are the poorly digested portions that pass through into the large intestine (bowel) and provide much of the bulk in our stools (along with water and bacteria, amongst a few other things).

There are a number of ways of classifying the different types of fibre. One of the most popular systems is whether they are soluble in water or not:

  • Water soluble fibres include gums (e.g. agar), fructans (e.g. inulin), mucilages (e.g. psyllium) and pectins. They are found in a range of foods including fruits, vegetables, legumes (beans, peas and lentils) and some grains (oats and barley)
  • Water insoluble fibres include cellulose, hemicellulose and lignins. They are mostly found in vegetables, wheat and other wholegrains, nuts and seeds. 
The different types of dietary fibres have different effects on our health.

Why we think fibre is good for us “Fibres promote one or more of the following beneficial physiological effects – laxation; reduction in blood cholesterol; modulation of blood glucose” says the second part of the FSANZ definition. Soluble dietary fibre may help reduce blood cholesterol levels and modulate blood glucose levels – but whether it does so or not depends in part on the degree of food processing and of course how much you eat. High cholesterol and blood glucose levels are risk factors for heart and other blood vessel diseases and type 2 diabetes and there is evidence that high fibre diets can indeed reduce the risk of heart disease, but perhaps surprisingly, there is little evidence that high fibre diets by themselves reduce the risk of type 2 diabetes. Insoluble dietary fibre primarily helps with laxation, which in turn may decrease the risk of constipation, haemorrhoids and colo-rectal (bowel) cancer.

Why most of us need to eat more Australia’s nutrition recommendations advise that women consume 25 grams of total fibre each day and men 30 grams each day. Based on the most recent nutrition survey, Australian intake is not far under the target amounts and way ahead of the US and UK with women eating 21 grams of fibre a day and men 27 grams. In the USA, women consume just over 14 grams a day and men just under 18 grams. In the UK, women consume 12.8 grams a day and men 14.8 grams a day. But, here’s what has been dubbed the Australian fibre paradox. Despite the relatively high average fibre intakes, Australians have some of the highest rates in the world of bowel cancer – ahead of the UK and US.

In part 2 (March), I’ll show how we can all incorporate more fibre into our diets in an enjoyable way, and talk about whether or not high fibre foods are low GI as many people think.

Q&A with Jennie Brand-Miller

Prof Jennie Brand-Miller answers your questions.

I find coconut water refreshing. But I have recently come across maple water. What is it? They say it is low GI. I am tempted to try it.
Maple water is the very same sap from the tree that they make the syrup from. It’s long been known as a refreshing drink straight from the tree when the sap is running in maple country, and not just in the US and Canada. In South Korea, drinking maple sap (“gorosoe”) is more than a springtime ritual, they have festivals and sap-drinking contests. Until recently, sap drinking had a very limited season as it could only be harvested during a narrow six-week window. According to the manufacturer of one of the launch brands, Kikki Maple Sweet Water®, “the sap is frozen to maintain its healthful benefits and maximize its fresh shelf life. At a local bottling plant, a hot fill process, with the liquid heated to just below 96 degrees Celsius, ensures that the drink remains below pasteurization temperature to preserve its purity, highlight the flavour and maintain healthful benefits. The product is then shipped, stored, and served chilled.”

Maple water

What’s in it? Kiki has about 60 calories (250 kilojoules) per 10 fluid ounce (300ml) serving. Its light maple sweetness comes from the 2–3 percent concentration of sugars in the sap, but that still gives you around 15g or 3 teaspoons of sugar (sucrose, glucose and fructose) in a serve – as does coconut water, if you want a comparison. There are claims that it is a low glycemic drink. But there is no actual GI value for it at present, as it has not been GI tested – I assume the claim is based on the GI value for pure maple syrup (GI 54). This is a hard one to guesstimate, and it would be good to see it GI tested (ditto coconut water). If it is only 2–3% sugars, then it empties faster from the stomach (like watermelon), so it could have a higher GI than maple syrup, depending on the balance of the sugars. Even so, the glycemic load would be low unless you drank several cups at a sitting as there is less sugar (carbohydrate) in it. There are other claims about its nutritional benefits including vitamins, minerals and polyphenols. We still think that it’s one for the occasional category, and not for everyday hydration. It’s the calories that not only count, but add up. To quench your thirst, it’s hard to beat water.

What about coconut water? 
We were recently asked about how healthy coconut water really is. We haven’t reviewed it, but Catherine Saxelby over at Foodwatch has. You can check out her report HERE.

The latest GI values from SUGIRS 
Rice syrup 
Also called: Brown rice syrup, rice malt syrup This is a mild-flavored, malted-grain sweetener that dissolves easily and is used in drinks and dressings, in baking and as a topping for cereals, waffles and pancakes. It is about one-third as sweet as regular sugar (sucrose) and is made by fermenting whole brown rice with enzymes that break down the natural starch content of the grain. The sugar composition of the final product is around 45% maltose, 3% glucose, and 52% maltotriose (a trisaccharide consisting of three glucose molecules joined together).

  • Glycemic index = 98
  • Available carbohydrate per 5g serving (1 level teaspoon) 4g 
  • Glycemic load per 5g serving (1 level teaspoon) = 4 
  • Glycemic load per 10g serving (2 level teaspoons) =8
  • Glycemic load per 15g serving (1 level 15-ml tablespoon) = 12
  • Glycemic load per 20g serving (1 level 20-ml Australian tablespoon) = 16

Food for Thought

More carrot, less stick might help do the trick.  
Taxes on ‘bad’ foods are the dish du jour in nutrition policy,’ says Prof J.T. Winkler in the BMJ commenting on a study where the authors propose even more taxes – just a bit higher despite acknowledging that most taxes are small, based on flawed evidence, and have limited, even negative, effects. ‘These are unlikely to be adopted and would be ineffective if they were,’ writes Winkler. While Katherine Rich, CEO of the New Zealand Food and Grocery Council pointedly notes: ‘I have heard many times the idea of food taxes. But I have never heard the idea of a food tax – be it sugar of fat – being championed by anyone who was not comfortably drawing a six-figure salary at the time.’

#1. Instead of talking taxes on ‘bad’ food, how about we tell the powers-that-be that we want them to look at ways of making the healthy choice the cheaper choice. A new meta-analysis from Harvard suggests that healthier choices do indeed cost more. The researchers report that diets rich in fruits, vegetables, fish, and nuts (which would indeed be healthy and low GI) – cost more than diets rich in processed foods, meats, and refined grains. Totting it all up, the Harvard team calculate that it costs about $1.50 more per person per day to make the healthy choice. Over a year for a family of four, that’s about $2200. We think, for some people, that's on the low side. Research shows that rural Australians pay much more for fresh food than city-dwellers do (A$9 for six mushrooms or A$4.50 for one small piece of broccoli or cauliflower).

 #2. Instead of talking taxes on ‘bad’ food, how about we tell the powers-that-be that we want them to look at ways of making sport and recreation more accessible and affordable for young and old. From swimming lessons (an essential), to signing up for winter and summer sports, taking part in organised sport is increasingly expensive (club fees and kit and travel), and out of reach of many families, especially single parent ones.

#3. Instead of talking taxes on ‘bad’ food, how about we tell the powers-that-be that we want them to be looking at ways of opening stairwells so we all can get more puff into our day. Prof Arya Sharma has suggested that perhaps we should be thinking of establishing codes for ‘active’ buildings. He describes the new Edmonton Clinic Health Academy where you are immediately faced with a wide open staircase (not stairwell!) on entering the building and the elevators are rather hidden in a corner.

#4 Instead of talking taxes on ‘bad’ food, how about we tell the powers-that-be we want them to boost food literacy and teach every child to cook says Nicole Senior. ‘Fast food is so much easier to avoid if you can whip up something tasty quickly. It’s so much easier to eat well if you know what to do with healthy ingredients (and you know what different ingredients are!). Every child should know milk comes from a cow and at the very least the difference between parsley and basil. Ideally they would know basil tastes divine with ripe tomato and how to grow them in the garden, pot or Styrofoam box. Food skills are living skills and if we build them up, we’ll be less vulnerable to unhealthy food marketing.’

Free fruit for kids

Harris Farm Markets keep a well-stocked barrel of fruit at the entrance of their produce stores. This picture was taken at the new Harris Farms Markets Bondi Beach store on Hall Street. We think this is a great ‘More Carrot, Less Stick’ initiative. ‘Thumbs Up’ from the GI News team. 

News and Reviews

The naturally low GI spud story. 
Everyone loves potatoes but they are often very high GI and a problem when managing BGLs. Back in 2007, when Prof Jennie Brand-Miller and Dr Alan Barclay saw the evidence mounting that it is the potato variety that effects glycemic impact not the cooking method, they sat down with potato expert Graham Liney, grower Frank Mitolo and Dutch potato breeding company Agrico to put a low GI potato on the table. Three years after the first crop was pulled from the soil, the not-so-humble Carisma was internationally certified as the first low GI potato (GI 55). They were developed from conventional plant crossings with other potato varieties and tested in field trials in Australia.
 Kai Lin Ek
 Kai Lin Ek, Accredited Practising Dietitian

Presenting at the International Congress of Nutrition in Granada in September 2013, Sydney University researcher Kai Lin Ek reported her findings that showed that Carisma ‘not only ranks well alongside other potatoes, but is also comparable with other low GI foods. Potatoes tend to get bad press because they are generally classified as a high GI carbohydrate but our research has discovered that Carisma has half the blood glucose response compared to other potato varieties,’ she said. ‘It has a similar GI to pastas, all of which are usually classified as low GI foods. But don’t overcook it. Any starchy carbohydrate has a higher GI if it is overcooked. If rice is mushy or pasta is not al dente you just increase the starch digestibility. Boiling for about nine minutes is the ideal cooking time to enjoy the health benefits and flavours of Carisma.’

Carisma potatoes

Developing a screening method for identifying further low GI potato cultivars is a health and agricultural priority. In a follow-up study published in the British Journal of Nutrition Kai Lin Ek reports that low GI potato cultivars could be identified by in vitro screening. In this study of seven potato cultivars she concludes, we found that: ‘GI values were strongly and positively correlated with the percentage of in vitro enzymatic hydrolysis of starch in the cooked potatoes. Amylose, dietary fibre and total starch content was not correlated with either in vitro starch digestibility or GI.’ Carisma potatoes are now grown all over Australia, and they are now in the ground in North America and Europe, so they will be commercially available in those regions in the near future.

Let’s put the GI facts on the table so consumers can make healthier choices. 
‘GI methodology is accurate and precise enough for practical use; GI is a property of foods; and GI is biologically meaningful and relevant to virtually everyone,’ writes GI pioneer Prof Tom Wolever in the European Journal of Clinical Nutrition addressing current criticisms that focus on GI’s validity. ‘None of the critics provide sound reasons for rejecting GI because some of their arguments are based on flagrant errors in understanding and interpretation while others are not supported by current data or are inconsistent with other nutritional recommendations.’

Wolever is concerned that current dietary guidelines recommend increased consumption of whole grains and dietary fibre, but do not mention GI. ‘This is illogical,’ he says ‘because the evidence that GI affects health outcomes is at least as good, or better, than that for whole grains and fibre. GI is a novel concept from a regulatory point of view and a number of problems do need to be addressed to successfully translate GI knowledge into practice. The problems are not insurmountable but no progress can be made until bias and misunderstanding about GI can be overcome and there is better agreement about what is the actual state of knowledge on GI so that the real issues can be identified and addressed.’ Speaking to GI News, Tom Wolever says: ‘I have nothing against recommending people consume more fiber and whole grains, my concern here is that these are not better markers of carbohydrate quality than a food's GI value.’ 

Bill Shrapnel on why sugar intake from soft drinks is falling.

Bill Shrapnel
Bill Shrapnel, Accredited Nutritionist

‘Carbonated soft drinks have been a major source of sugar in the Australian diet for decades. In 2007, Dr Gina Levy and Professor Linda Tapsell published an analysis of sales of soft drinks and other water-based beverages in Australia between 1997 and 2006. There were three key findings – beverage sales were increasing; there was a shift away from sugar-sweetened to non-sugar drinks; and the per capita contribution of sugar from these beverages to the national diet was declining. Recently, Gina Levy and Bill Shrapnell conducted a study to update the earlier findings of Levy and Tapsell. Their objective was to assess trends in sales of soft drinks and other water-based beverages over a 15-year period, from 1997 to 2011. The paper has been accepted for publication in Nutrition and Dietetics and Gina Levy presented their findings at the ‘Sweet Symposium’ in Sydney on 2 December 2013. The most interesting finding from this study was the fall in the sugar contribution from carbonated soft drinks from 8.4kg (about 18 pounds) per person in 1997 to 6.2kg (about 13 pounds) per person in 2011. In relation to the broader category of sugar-sweetened beverages, per capita sugar contribution fell over the 15-year period from 9.2kg (about 20 pounds) to 7.6kg (about 16½ pounds). The reason for the decline in the contribution of sugar from these beverages is the ongoing, long-term decline in the proportion that is sugar-sweetened, from 70% to 58% of the total. This is largely driven by a substantial shift in carbonated soft drinks from sugar-sweetened to non-sugar drinks. Over 15 years the proportion of carbonated soft drinks that is sweetened with sugar has fallen from 64% to 45% of the total. There has been a corresponding increase in the proportion of non-sugar soft drinks (e.g. diet soft drinks with non-nutritive sweeteners) and still water. The traditional drivers of the soft drink market have been indulgence and convenience. It now appears as though increasing health consciousness, especially in relation to body weight, is making its presence felt.’ To read more, head over to The Sceptical Nutritionist.

Reviewing the role of fructose, sucrose, and HFCS in diabetes.  
‘There remains a lack of consistent evidence to suggest that fructose, sucrose, or HFCS at moderate doses is directly related to the development of diabetes and other cardio-metabolic diseases, although there is potentially cause for concern where fructose is provided at high doses or contributes excess energy to diets’ write Drs John Sievenpiper and Al Cozma in US Endocrinology. But ‘many questions remain unanswered,’ they say. ‘High-quality trials are needed to assess the role of fructose-containing sugars in free exchange with foods likely to replace them in the diet in the development of diabetes and cardio-metabolic diseases.’

Raspberries to that 
Ever wondered where the term ‘blowing a raspberry’ came from? It’s kinda obvious in a way because the shape of your mouth when you blow a raspberry looks a bit like a raspberry, but the real low-brow humour comes from the English rhyming slang ‘raspberry tart’ for fart- the noise blowing a raspberry. Ahem, moving right along.
Raspberries
Raspberries are my all time favourite because of their mouth-watering tang and subtle sweetness. It’s a pity they are expensive as they are one of the few fruits you can eat by the tub without blowing your kilojoule budget. One of the main reasons they are expensive is they are highly fragile and have a short shelf life. Their velvety skin is easily damaged and their softness prone to mushiness. Of course even in this less than perfect state they are fine to use in recipes (they’re too good to waste). Look for raspberries in good shape (plump) and rich in colour and store them in the fridge in a single layer on some paper towel. I would recommend you eat them as soon as you get them home while they are still perfect but they will last in the fridge for a few days if they were fresh when you bought them. If by chance you have a surplus, they can also be frozen for up to a year, either in a freezer bag (in a single layer) or suitable solid container. Another reason raspberries are so special is their fleeting availability only during summer. Luckily they are available frozen to prolong the pleasure through the year and are perfectly fine to use in muffins, loaves, friands, crumbles, tarts and pies, smoothies and yoghurt.

You may not know that raspberry bushes are covered in sharp hairs so in the days before commercial production they were an even greater prize due to the pain incurred during the harvest. Raspberries are easy to grow but easily spread by popping up new stems from the roots underground. Plant them where you won’t mind them getting away, or be prepared to remove the new runners should they pop up where you don’t want them.

When it comes to nutrition raspberries are in the top of the charts for phytochemicals, including ellagic acid, anthocyanins, flavonoids, phenolic acids and tannins that play a variety of roles to benefit health such as reducing oxidative stress and inflammation, enhancing insulin action, and reducing cancer cell activity. They are also rich in vitamin C and fibre, and contain vitamin E, folate and manganese. Just one cup provides around half the daily recommended intake of vitamin C.

While raspberries are divine eaten fresh they also add something special to porridge or muesli, fresh squeezed juice, smoothies, yoghurt and fruit salad. And they play a starring role in desserts such as crumble, syllabub, pudding and parfait. If you’re fortunate enough to grow a bumper crop, raspberry jam, jelly and sauce are marvellous ways to keep the good times rolling. Try serving jam on some wholegrain toast with ricotta for an almost-cheesecake experience, and drizzle the sauce over ice cream or yoghurt and garnish with your favourite nuts. Raspberry coulis (pronounced koolie) is simply a sweetened sauce with the seeds strained out and fabulous on just about anything. I would remiss if I didn’t also mention how well raspberries partner with chocolate, especially the dark, rich, not-too-sweet kind. Top your favourite chocolate dessert with fresh raspberries or raspberry sauce/coulis to take bliss to a whole new level. I will never blow another raspberry again!

Nectarine and raspberry crumble 
This summery fruit crumble plays on the heavenly aroma and flavour of ripe nectarines alongside the refreshing tang of juicy raspberries, all topped off with a deliciously nutty crumble mix. Remember, the tablespoon I use is the 20ml Australian tablespoon (equals 4 teaspoons). Serves: 8

800g (just under 2lb) ripe, white nectarines, cut into eighths
300g/10oz frozen raspberries
1 tbsp honey

Crumble topping 
½ cup rolled oats
¼ cup (lightly packed) brown sugar
2 tbsp LSA (ground linseeds, sunflower seeds and almonds)
1 tbsp sesame seeds
1 tbsp sunflower seeds
½ tsp ground ginger
40g/1½ oz butter or margarine cut into 1cm/½in pieces
¼ cup natural almonds, coarsely chopped

Honey yoghurt 
1 cup reduced fat Greek-style yoghurt, to serve
1 tbsp honey

Nectarine and raspberry crumble
Photo: Georgie Esdaile

Preheat the oven to 180ºC/350F. Line an oven tray with non-stick baking paper.
To make the crumble topping, place oats, sugar, LSA, sesame seeds, sunflower seeds and ground ginger in a bowl, mix to combine. Add the margarine and use your fingertips to rub in until the mixture resembles coarse breadcrumbs. Stir in the almonds.
Place the nectarines and raspberries in a bowl, drizzle with the honey and mix gently to combine. Divide the fruit among eight ¾ cup ramekins or ovenproof dishes and place on the oven tray. Sprinkle each evenly with the Crumble Topping.
Bake in preheated oven for 20-25 minutes until the crumble is crisp and golden and the fruit is tender when tested with a skewer. Meanwhile ...
To make the honey yoghurt, combine the yoghurt and honey in a small bowl and stir until evenly combined. Serve with the crumble.

Baker's tips

  • Store any leftover crumble in the ramekins covered with plastic wrap or in an airtight container in the fridge for up to 3 days. 
  • Serve cold or reheat in an oven preheated to 180C/350f for 10-15 minutes. 
  • This crumble can also be baked in a 2-litre (8-cup) ovenproof dish at 180C/350F for 30-35 minutes. 
Baking tins
You may have noticed that traditional enamel bakeware is making a comeback. Available in a variety of sizes I find it is perfect for making crumbles, vegetable bakes and roasts or even to serve from – salads in particular. If you love the dish I have used here, the brand is Wiltshire and it is available in Australia through Woolworths and David Jones. There are various sizes. I used the individual dishes for the crumble.

Baked winter pears with fresh grape juice sauce 
Here is a wholesome, no-sugar-added, naturally sweet dessert coming to you from Mother Nature herself while on one of her trips to Italy! Serves 6 (a pear per person)

Grape sauce 
4 lb (1.8 kg) red or black grapes with or without seeds
1 cup red wine such as Cabernet, Merlot, etc.

Baked pears
6 large, firm pears (Bosc), halved, peeled and cored
¼ teaspoon ground cardamom

Baked winter pears with fresh grape juice sauce

To make the grape sauce Remove the stems from the grapes, wash and pat dry. Add the grapes in batches to a food processor and finely chop • Place the chopped grapes in a container with a lid and refrigerate for 2–3 days • Strain the grapes through a sieve into a large pot – be sure to press out as much liquid as possible and to scrape off the pulp from the bottom of the sieve and add to the liquid • Cook the grape juice, uncovered, over medium-high heat for approximately 30 minutes. The liquid should reduce down to about ¾ cup. • Add the wine and boil for 1–2 minutes. Set aside.

To make the baked pears Preheat the oven to 375F (190C) • Place pear halves, cut side down in an 11-inch (20cm) round baking dish. Sprinkle the cardamom on the pear tops • Bake until a knife easily pierces through, approximately 40–60 minutes (depending on ripeness). Baste 3–4 times with the grape sauce. When the pears are done, remove from the oven.

To serve There are two serving options with this dessert • You can simply pour the grape sauce and pan juices into a gravy boat and serve with the warm (or room temperature) pears • Alternatively, you can transfer the grape syrup and pan juices into a small saucepan and rapidly boil it down until it thickens and starts to caramelize (3–5 minutes). Quickly pour the reduction over the pears, forming a type of glaze.

Vino cotto 
If you slowly reduce unfermented grape juice, you end up with a velvety, sweet condiment that compliments desserts and savory dishes. If you don’t have time to make your own, look for vino cotto in larger supermarkets and gourmet stores. It tends to be an artisanal product, but more brands are appearing on the shelves. We tried Il Baronello (with quince) drizzled over plain yoghurt, and also in a rocket, pear, walnut and parmesan salad. Angela Galtieri, whose family who started Il Baronello, says: 'Encouraged by interest from adventurous home cooks, we began producing vino cotto. We had also noticed that older generations of Italians no longer made their own (it’s very hard work), and preferred to buy it when they needed it for their traditional sweets.' Vino cotto itself has not been GI tested, but Chateau Barossa grape syrup (essentially the same thing) has a GI of 52. Make sure the ingredient list simply says '100% grape must' plus any other additional fruit flavouring.

Summer barbecue for easy meals and entertaining 
Barbecued prawns with avocado and mango salsa
Here at GI News, we always enjoy Luke Mangan’s recipes, and have published several over the years as he has lovely ideas for using low GI ingredients like lentils and corn. This recipe is from his new book, Salt Grill: Fine dining for the whole family (Murdoch Books). With mangoes in season here in Australia, we couldn’t resist. Serves 4.

16 fresh king prawns (shrimp), peeled and deveined, tails left intact
A little extra virgin olive oil, for drizzling
¼ iceberg lettuce, thinly sliced
1 avocado, diced
Vietnamese mint leaves, to garnish

Mango salsa 
2 small ripe mangoes
¼ red onion, very finely diced
1 red chilli, seeded and finely chopped
2 tbsp roughly chopped Vietnamese mint
2 tbsp roughly chopped coriander (cilantro) leaves
1½ tbsp chardonnay vinegar or white wine vinegar
1 tbsp extra virgin olive oil

Barbecued prawns with avocado and mango salsa

Peel the mangoes, then cut off the cheeks and as much flesh off the stones as possible. Dice the mango flesh and place in a mixing bowl. Add the remaining salsa ingredients, season with sea salt and freshly ground black pepper and mix lightly.
Place the prawns on a tray. Season and drizzle with just enough olive oil to coat the prawns. Place the prawns on a hot barbecue or frying pan and cook for 2 minutes on one side. Turn the prawns over and cook for a further 2 minutes. Remove and rest on a plate for another 2 minutes.
Add the lettuce to the mango salsa and place on a platter. Scatter the prawns and avocado on top. Garnish with Vietnamese mint.

Putting the Fun Back into Fitness

Paddling.  
Here in Australia, it is fair to say that kayaking or ‘paddling’ is in. The minute I sit in a kayak with a paddle in my hands and feel the sensation of the criss-cross motion gliding through the water, all cares vanish. Prof Jennie Brand-Miller tells me that she has an ‘industrial strength’ blow-up kayak and like me, she finds paddling around the harbour with her husband, John and their miniature poodle, Sacha, a complete release and a great workout.

Kayaking is a low impact activity that can improve your aerobic fitness, strength and flexibility. You can take up paddling as a hobby, a competitive sport or for an active holiday (there are kayaking safaris). However, no activity is for everyone. People with tight hip flexors or bad backs often find the seated posture in a kayak painful.

When you kayak with the correct technique – pushing the pegs with your legs, engaging your core muscles, and working your torso and arms with a criss-cross figure 8 motion – you work your entire body without strain, using the resistance of the water. Wind, tide and current can add additional pleasure, exhilaration, motivation and cardiovascular effort.

On top of this, you can experience the beauty of the world around you from a unique perspective, discovering new nooks and crannies in familiar places. Kayaking has transformed travel for me, and I now hunt down places to paddle wherever I roam – Perth, the Whitsundays and Israel so far, with Hawaii and Switzerland on the agenda for 2014.

Canoeing in the Whitsundays

Paddling in the Whitsundays

To get started, it’s a good idea to take some lessons, or join a local paddling group or club. People of all ages and levels of fitness can enjoy canoeing and kayaking, but you need to be properly prepared (and that includes stretching before and after) and use your common sense. Better Health Victoria has an excellent fact sheet on safe paddling and kayaking.

Emma Sandall runs Body Playground, an online space for discovering how to put the fun back into your fitness routines. With fellow Body Playground director and Pilates teacher, Peta Green, she has developed a new and expressive style of workout that brings together the technical and fluid aspects of Pilates, yoga and ballet.

Low GI foods and drinks help kids keep in shape
While it’s common knowledge that adults around the world are piling on the pounds, we sometimes overlook the fact that our children live in exactly the same obesogenic environment and that they too are increasing in girth at a faster rate than they are increasing in stature. Here in Australia, for example, 1 in 4 children aged 5-17 years were classified as overweight or obese in Australia's most recent national nutrition survey.

A new systematic review and meta-analysis of low glycemic index and load diets in children has shown how consuming low GI/GL meals and snacks can help children prevent weight gain. The researchers identified six studies that included 213 children aged from four to seventeen and found that kids can reduce their average energy intake at the next meal by approximately 600 kilojoules (145 calories) by choosing healthy low GI alternatives.

The authors report that: “The underlying mechanism regarding the relationship between GI and energy intake is glucostatic hypothesis. In this theory, decrease and increase in blood glucose level is the main determinant of hunger and satiety, respectively. L[ow] GI foods provided sustained blood glucose levels. Thus, feelings of hunger are delayed following an L[ow] GI meal compared with an H[igh] GI meal.” This new level 1 evidence (the highest) builds on results from the recent Diogenes study that found that a higher protein, low GI diet is the best eating pattern for longer term weight maintenance in children aged from five to eighteen.

Child eating apple

Most kids like to graze on small meals and snacks throughout the day. By providing healthy low GI snacks between meals you can help your children reduce their overall kilojoule/calorie intake at their main meals. Healthy low GI snacks for children include:

  • Fresh fruit (apples, grapes, pears and other temperate fruits) and fruit salad 
  • Canned/bottled fruit 
  • Dried fruit (apple, apricots, dates, peaches, pear, prunes) 
  • Fruit and nut mix 
  • Reduced or low fat plain milk 
  • Reduced or low fat flavoured milk (e.g., Milo)
  • Reduced or low fat yoghurt (plain or with fruit) 
  • Low GI bread (Burgen, Tip Top 9 Grain or Mission corn tortilla all carry the GI Symbol) with a favourite spread or topping (e.g., hummus)
  • Raisin toast with a scrape of jam 
  • Wholegrain crackers and crispbreads
  • Muesli bars (e.g., Uncle Toby's Crunchy or Chewy varieties)
  • A small bowl of breakfast cereal (Kellogg’s Sustain or All Bran Fibre Toppers) with reduced or low fat milk

Q&A

Guest contributor, Dr David Katz, gets to ask and answer the first Q&A for 2014. 

Dr David Katz
Dr. David Katz

‘When I ask my patients why they’ve come to see me, the answer is always to get better if something is wrong, or to get advice about staying healthy if nothing is currently bothering them. My second question is “Why do you care about being healthy? What is health for?”
Usually these questions are met with silence. No one really thinks about the fact that health is for something, but it is. It’s for living the life you want, for feeling good and functioning at your best. It’s a reward and a return on your investment in yourself. That’s true of the money we put aside to secure our futures or pay for our kids’ educations, and it’s certainly true of the effort we devote to improving our health. After all, your life will be better if you have good health. And if you pay it forward by sharing your health-promoting, disease-fighting strategies with your loved ones, your life will be better still because the people you love will share good health with you.

It requires effort and practice to make these skills automatic, especially given the world we live in. We didn’t choose to be born into an environment that promotes obesity, but here we are, nevertheless. We did not choose to find ourselves in a world awash with highly palatable, energy-dense convenient foods. And while we did not choose to be among the first generation of Homo sapiens that could count on technology to do everything for us, in areas ranging from work to recreational pursuits, once again, here we are. You don’t need to be gluttonous to overeat or lazy to underexercise and gain weight in the modern world; you simply need to live in the modern world, which is why obesity and chronic disease are not exceptions – they are now the norm.

There’s a place for both personal policy and public policy in fixing what ails our collective health. Remember, while you’re waiting for the world to change, it is possible to steer a course of your own and your family’s to better health. It’s called lifestyle. And it is the best medicine there is, ever was, and likely ever will be. At a fork in the road for health care, our economy, our culture, and what the future holds for our children and grandchildren, each of us holds a spoon that could get this medicine to go down. When you prescribe yourself lifestyle as medicine you will discover that you can:

  • Build skills to improve your eating habits at home and on the road, your food shopping and cooking habits, and your level of physical activity. 
  • Retrain your taste buds to prefer healthier foods, discover physical activities you enjoy and fit them into your life, and embrace the gift of physical activity. 
  • Improve other aspects of your lifestyle including your sleep, stress, pain and social connections so they can enhance your eating and exercise habits. 
When you prescribe yourself lifestyle as medicine, you are the doctor for yourself and those you love. But as with all doctoring, it requires a skill set. If you don't have it, you can get it. No other medicine can do what lifestyle can do, and no one else can practice lifestyle for you. It's your life, and only you can live it. If you empower yourself, if you acquire the requisite skill-power to take lifestyle as your medicine, it will almost certainly be a better life. Healthy people have more fun.’

This is an edited extract from Dr Katz’s new book (with Stacey Colino), DISEASE PROOF, where shares the very skill set on which he and his family rely to enjoy lifestyle as medicine.

Disease-Proof. DNA is not destiny.

Food for Thought

Health-by-design at the festive table
The holiday season is rapidly approaching and chief cooks in households around the world are starting to think about what festive fare to serve family and friends (of course the better organised ones have already made the Christmas puddings, mince pies and cakes). Serving the special foods that are part of your cultural traditions is part of the ritual and something everyone looks forward to. In my family, ensalada rusa (Spanish potato salad) will always be on the buffet table along with other traditional Spanish and Aussie Christmas fare. It’s all so tempting, it's hard not to overfill your plate ...

The big problem these days with our festive fare is that the holiday season seems to have spread way beyond that special Christmas eve dinner or Christmas lunch with parties and celebrations galore, each vying for your eating affections. However each time you overload your system with excessive food, it’s akin to metabolic assault: your blood becomes milky with fat (post-prandial lipaemia); glucose, insulin levels and inflammatory hormones rise; your blood vessels become less flexible (called endothelial dysfunction) and your blood becomes more likely to clot (or pro-thrombotic). Unfortunately for those with diabetes or pre-diabetes, these adverse effects are worse.

And did you know that rather than signalling the body to ease-off at subsequent meals, huge meals can actually increase appetite for the next meal perpetuating a vicious cycle of overeating (people often say their stomach has stretched). It’s no wonder hospital emergency rooms experience a rush of cardiac patients on Christmas and Boxing Day.

Surely it’s time to move on? The planet can no longer sustain such excess and our physical health is suffering as a result. Not to mention the moral affront of gluttony in a world where there is so much hunger, plus the environmental disaster of food waste.

  • If you are catering, be bold in offering healthier options and cook the right quantities to avoid waste. Don’t pressure guests to eat more than they need.  
  • If you’re on the receiving end of pressure to eat more than you want to, be kind but assertive. Your health and comfort need not suffer to please others. 
Of course, many of the adverse effects of overeating can be reversed by exercise, but it’s hard to throw a ball around when you’ve fallen into a postprandial stupor and can’t get out of your chair. Perhaps the best test of eating the right amount is having some get-up-and-go a few hours after getting up from the table? Some research conducted by Professor Brian Wansink from Cornell University might help. He found that placing the healthy items first on the buffet table helped diners fill their plates first with these better choices. I’m sure we could all could utilise a little health-by-design at our festive table to steer our guests towards more of the good stuff as well.

Sincere best wishes to you and yours for a happy and healthy festive season.
