FOOD FOR THOUGHT
RICE AND RISK OF TYPE 2 DIABETES
Around the world, the prevalence of type 2 diabetes continues to
climb. The rate of increase is particularly high in countries such as
China and India, the most populous nations on the planet. China and
India are also similar in the sense that rice is their staple food.
Although there have been changes in lifestyle, nutrition and physical
activity, rice remains a favourite food. Indeed, rice provides about
20% of all calories eaten globally. White rice is still preferred over
brown rice, but there have also been more subtle changes in milling and
polishing that have altered the inherent nutritional properties of
rice.
A long time ago, I recall reading a magazine article about the many different varieties of rice. Even though I had already devoted 4 years to training in Food Science, I was amazed to learn that ordinary people distinguished between different types of rice, favouring one versus another, depending on the cuisine. To me, at that time, rice was rice! I learned that some people liked Jasmine best - the grains were fluffy and slightly sticky. They clumped together, making them ideal for eating with chopsticks. Other varieties such as Basmati were not at all sticky and individual cooked grains could be picked out one at a time. Basmati was the favourite for curries and other Indian dishes.
Today, we can find many varieties of rice on supermarket shelves, including short grain, long grain, medium grain, Arborio (ideal for making risottos) and sushi rice (short-grain Japanese rice) for making sushi. There’s also black rice, red rice, wild rice and Doongara (Clever Rice™) – a new variety developed in Australia to compete with Basmati.
One of the first research projects that I was to carry out as a scientist was on the GI of different rices sold in Australia. We compared 10 different rice products – 3 were commercial rices with different levels of amylose starch, a waxy variety with only 2% amylose, a converted (parboiled) rice, a quick cooking brown rice, puffed rice cakes, rice pasta and rice bran. Amylose starch is a straight-chain molecule that lines itself in rows, making it more difficult to gelatinise than the other form of starch called amylopectin. Higher temperature and more water is needed to cook high amylose varieties of rice.
The GI values varied, ranging from medium to high on a scale where glucose = 100. The low amylose Pelde variety gave the highest GI (93), while the high amylose rice gave the lowest GI (64). The quick-cooking brown rice also had a very high GI (80), as did the brown rice pasta (92). Interestingly, white rice and brown rice have similar GIs. It was the variety that was important, rather than the grain size, degree of milling or parboiling.
So here once again, the GI concept turned conventional nutrition wisdom on its head. It was wrong to automatically assume that a brown rice would have a lower GI than white varieties.
In November 2020, the prestigious journal Diabetes Care, carried a paper and editorial about the link between eating rice in large amounts and the risk of developing type 2 diabetes. The PURE study was an observational study in over 130,000 individuals from 21 countries. On average, people were followed-up for 10 years, during which time just over 6000 developed diabetes.
The authors found that those who ate more than 450 g per day (that’s around 2.5 cups of cooked rice) were more likely to have a diagnosis than those who consumed less than 150 g per day (less than 1 cup). In scientific wording, their risk was 20% more.
However, people from South Asia (India) were substantially (60%) more likely to have developed diabetes when rice was eaten in large amounts. People from South East Asia, the Middle East, South America and Africa were also more at risk, but not as much as those from South Asia. Surprisingly, there was no association between the amount of rice consumed in China and the risk of diabetes.
These mixed findings are difficult to explain on the grounds of differences in GI alone. We know that a diet with a higher GI and glycemic load will increase the risk of type 2 diabetes, but in the PURE study, the lower GI variety (Basmati) is associated with more diabetes than the higher GI variety consumed in China.
There are other possible explanations, e.g., the presence of toxic elements such as arsenic in rice grown in India. Also, some have interpreted the results of the PURE study as an indicator of a “poverty diet”, rather than nutrition. Most study participants located in low-income countries subsisted almost entirely on carbohydrates, “especially from refined sources.” A “poverty diet”, which is common in poor rural areas, is also typically high in sodium and low in animal products and vegetable oils. In this situation, it is extremely challenging if not impossible to separate the effects of diet from poverty and undernutrition.
Indeed, the South Asian (Indian) diet is higher in saturated fat (ghee is a popular cooking fat) that increases insulin resistance and the demand for insulin secretion. Over time, insulin resistance worsens, and the beta-cells eventually fail, despite the rices lower GI. Moreover, in China, the alternative to high GI rice is a large range of wheat products (including bread and dumplings) that also have a high GI.
And finally, as I often say to my students and colleagues, nutrition science is still very young, it’s very complex and we have lots to learn.

WHAT’S NEW?
WHOLEGRAINS AND RISK OF DIABETES
A new study published in the British Medical Journal has found that a higher intake of wholegrains is associated with a lower risk of developing type 2 diabetes.
Researchers combined the findings from three large prospective cohort studies – the Nurses’ Health Study, The Nurses’ Health Study 2 and the Health Professionals Follow-Up Study. Together, they included 158,259 women and 36,525 men who did not have type 2 diabetes, cardiovascular disease, or cancer when the studies began. Participants completed a dietary questionnaire at the start of the study and every four years, and another questionnaire to identify newly diagnosed type 2 diabetes and other health conditions every two years. The average follow-up period was 24 years.
In this study, the researchers looked specifically at intake of total and individual whole grain foods and the risk of type 2 diabetes.
After adjusting for other lifestyle and dietary factors which might affect diabetes risk, participants with the highest intakes of wholegrains had a 29% lower risk of type 2 diabetes compared to those with the lowest intakes.
The researchers also looked at specific wholegrains including wholegrain breakfast cereals, wholegrain breads, oatmeal and brown rice. People who ate 1-2 serves of wholegrain cereal or breads per day had around a 20% lower risk of developing diabetes compared to those who ate these foods less than once per month. And those who ate oatmeal or brown rice once or twice per week had a 21% and 12% lower risk, respectively, than those who ate these foods less than once per month. Physical activity, family history of diabetes and smoking status didn’t affect the findings but the association between wholegrain intake and diabetes risk was stronger in those who were lean compared to those carrying excess weight.
These findings are consistent with previous studies showing a lower risk of type 2 diabetes associated with wholegrain, but not refined grain, intake. When it comes to rice, previous research has found that higher intakes of white rice were associated with an increased risk of type 2 diabetes and it was estimated that replacing 50g (uncooked) per day of white rice with brown rice could reduce diabetes risk by 16%.

PERSPECTIVES: Dr ALAN BARCLAY
RICE: THE GO-TO GRAIN
English translation: “Have you eaten rice?”
This popular greeting used throughout East Asia is a reminder that traditionally food was scarce and people were often starving. Rice saved lives, so it’s not surprising that the word for “rice”, “food” and “meal” is one and the same in Chinese—and in many other parts of East Asia, too.
Those early farmers who planted the first seeds some 10,000 to 8,000 years ago in Southern China would be gobsmacked at the number of varieties that have evolved (more than 100,000 it is estimated) and at their colours (white, red, black), sizes, shapes, aromas, stickiness and starchiness. And at all the things we make with the grains from flour, noodles, and crackers to syrup, alcohol, oil and puffed breakfast cereals.
In wok, pot or bowl or on a plate, rice soaks up the flavours from stocks and sauces and partners with meat, chicken, fish, seafood, tofu, vegetables, nuts, or fruit in snacks, soups, salads, sides, pilafs, paellas, risottos, desserts and more.
WHAT TO LOOK FOR
Nutty-tasting brown rice with just the inedible hull removed is
the rice with the serious nutritional wholegrain credentials. This is
because it contains all parts of the grain — including the fibrous bran,
the nutrient-rich germ and the starch-rich endosperm. Because of this,
brown rice has more dietary fibre, antioxidants, vitamins and minerals
than white rice. But it tends to be slow cooking.
However, these days we can buy 2-minute microwave options to help get meals on the table fast. Refined, popular, palatable white rice is still an ok choice, especially when combined with lots of veg. For speedy meals rice noodles are good to have on hand. Look for lower-GI varieties.
LOWER GI RICES - THE AMYLOSE FACTOR
The starch in raw food is stored in hard, compact granules that our
bodies find hard to digest, which is why starchy foods usually need to
be cooked. Water and heat expand the starch granules during cooking to
different degrees; some actually burst and free the individual starch
molecules (this is gelatinisation). Rice is a great grain for getting to
know the starches in our foods— amylose and amylopectin.
- Amylose is like a string of glucose molecules that tend to line up in rows and form tight, compact clumps that are harder to gelatinise and digest. The lower GI rices have a higher proportion of amylose.
- Amylopectin is a string of glucose molecules with lots of branching points, such as you see in some types of seaweed. Amylopectin molecules are larger and more open and the starch tends to be easier to gelatinise and digest. Higher GI rices have a higher proportion of amylopectin.

DIABETES CARE
RICE AND THE MANAGEMENT OF DIABETES
Due
in part at least to the current popularity of “low carb” diets, people
with diabetes are often advised to at the very least severely limit, if
not completely avoid rice. This is of course a major issue for people
who traditionally eat rice for all of their main meals (breakfast, lunch
and dinner), like many people from South and East Asia. For these
people, complete avoidance is not really a long-term strategy for
success, as it goes against their cultural and personal food
preferences. What are the alternatives, if any?
Portion caution
Cooked rice is indeed a concentrated source of starchy
carbohydrate. As can be seen in this month’s “Your GI Shopping Guide”, a
quarter of a Cup of most cooked rices provides around one carbohydrate
exchange (12-18g carbohydrate per serve). While everyone with diabetes
should see a dietitian for personalised advice, as a general guide, the
carbohydrate recommendations for main meals for adults are:
Men 45 – 60 grams of carbohydrate, or 3 – 4 exchanges
Women 30 – 45 grams of carbohydrate, or 2 – 3 exchanges
So, if you are going to continue to enjoy rice for breakfast, lunch and dinner, aim to have less than 1 cooked Cup at each meal. Bulk the meal out with non-starchy vegetables (e.g., alfalfa sprouts, asparagus, bean sprouts, bok choy, broccoli, Brussel’s sprouts, cabbage, capsicum, cauliflower, celery, chives, cucumber, eggplant, endive, garlic, green beans, kale, lettuce, leeks, marrow, mushrooms, okra, onions, radish, rocket, shallots, silverbeet, spinach, squash, tomatoes, watercress, and zucchini) and some lean protein (e.g., eggs, lean meat, seafood, skinless poultry or tofu).
Swap it, don’t stop it
There are literally thousands of varieties of rice grown around
the world. We have measured the GI of only a small portion of them.
While many varieties have a high GI (>70), not all varieties do.
Lower GI varieties are becoming increasingly available in both South and
East Asia, to suit the culinary needs of the local population. See this
month’s “Your GI Shopping Guide” for some more common examples and
ideas.
Glycemic load counts
The glycemic load (GL) is the amount of available carbohydrate
(grams) in a serve of food, multiplied by its GI value (which is a
percentage):
GL = available carbohydrate per serve X GI value ÷ 100.
Each unit of GL is equivalent to 1 gram of pure glucose – the sugar people measure in their blood with their home blood glucose meter when they have diabetes. So, by choosing the lower GI variety of your favourite rice, and eating it in smaller portions, you can potentially cut the glycemic impact of the rice you eat in half.
Long-term success
For those people who have enjoyed eating rice for their main
meals for most of their life, complete avoidance or severe restriction
is not a recipe for long-term success. As the scientific evidence base
shows us, many people can adhere to a “low carb” diet for 6 months, but
most can’t for 12 months or more. It is therefore arguably better to
enjoy a smaller amount of high-quality rice on a regular basis, than to
try to avoid it.

YOUR GI SHOPPING GUIDE
WHICH RICE?
Preparing this article on the GI of rice turned out to be way
more difficult than I anticipated. There are literally hundreds of
studies that have looked at the GI of rice and identified virtually as
many GI values! I’ve chosen just a few varieties of rice to profile in
this month’s shopping guide, and simplified the evidence, but if you
would like to read more see the reference below.
Generally, rice should be considered a medium to high GI food with the potential to contribute a significant glycemic load to our diet. To moderate its glycemic impact you could consider:
- Species - high amylose rice (think long, firmer grains that expand less during cooking) has lower GI values than high amylopectin varieties (think shorter grain, waxy, sticky or glutinous rice)
- Preparation technique - shorter cooking times and steaming, rather than boiling, tend to lower GI. Cooling cooked rice by refrigeration increases resistant starch and lowers the GI
- Accompaniments - eating rice with vinegar (as in sushi) or with pickled foods can lower the GI, as can incorporating soluble fibres such as those from barley and legumes And finally
- Portion size - a smaller serve will have a lower glycemic load

GOOD CARBS FOOD FACTS
BLACK RICE
Have you noticed a trend toward black foods, such
as bread with charcoal, black seaweed, black sesame and squid ink?
Perhaps this is because they are unusual, or because they look great and
really ‘pop’ on the plate making for Instagram (black) gold. Black rice
is another black food that is enjoying popularity and is now widely
available.
Black rice is a variety of regular rice Oryza sativa. In ancient China black rice was known as forbidden rice as only the wealthy could afford it. Now you can buy it in the supermarket, although it is a little more expensive than regular rice. I’ve seen it labelled as a ‘super food’ and while we may not be used to seeing rice labelled this way, it does have something special. The black colour is due the presence of an antioxidant called anthocyanin, which is also found in blue and purple fruits and vegetables such as berries, grapes, plums and cabbage. Besides looking gorgeous, anthocyanins are also good for you because they have antioxidant and anti-inflammatory properties that might help reduce the risk of numerous diseases such as cardiovascular disease, type 2 diabetes and even cancer. This sounds pretty ‘super’ to me, but I think lots of foods are super. It is also a good source of magnesium and a source of B-vitamins thiamine and niacin, and 1 cup of cooked black rice has just over 3g of fibre as most black rice is wholegrain and still has its bran layer. Black rice is naturally gluten free and offers a bit of excitement and variety in a gluten-free diet for those with coeliac disease or gluten intolerance.
Many rice varieties have a high glycemic index (GI), several have medium GI, but unusually black rice appears to have a low GI. There is only one black rice listed on the GI database, and it is a Chinese black rice porridge that has a GI of 42 (low). With most rices the main determinant of GI is the balance of the two main starches present, amylose and amylopectin. However, in black rice it is likely that the high levels of anthocyanin antioxidant is also slowing down the absorption of the carbohydrate and thus lowering the GI.
Black rice keeps its shape and is chewier than polished white rice and has a nutty flavour. It also takes longer to cook, around 35 minutes. To save time, try cooking up a big batch, freeze meal-sized portions and take one out as you need it. Black rice is perfect for rice salads, rice bowls, pilafs, risotto, paella, fried rice and as a base for curries and stir-frys and even as a sweet rice pudding dessert.
