Busting Food Myths with Nicole Senior

Myth: People with diabetes shouldn’t eat sugar

Fact: People with diabetes can enjoy sugar in moderation as part of a healthy diet.
Do you believe that all chocolate and candy or lollies cause a rapid spike and then crash in blood glucose levels? You’re not alone. If you ask anyone walking down the street what they think a diet for people with diabetes should include, chances are the first thing they’ll say is ‘no sugar’. It’s one of the most pervasive and persistent myths about diet and health ever, I reckon. Yet it is a myth.

The downfall of the ‘no sugar’ dietary dogma started with the advent of the glycemic index (GI). The GI was the first means by which we could actually measure the effect of different foods on our blood glucose levels and it turned the nutrition world upside down. Before the GI we separated carbs into starches and sugars, and recommended ‘complex’ starchy foods over ‘simple’ sugary foods in the mistaken belief they would not raise your BGLs to the same degree. We were wrong. Measuring the GI of a variety of starchy and sugar foods turned the old advice on its head. We discovered most bread, potatoes and rice had a high GI, whereas table sugar and most honey had a moderate GI. Even more shocking was that sweet tasting foods such as (most) fruits, flavoured yoghurt and ice cream had a low GI! The shockwaves of this scientific development are still being felt. Even the terminology has changed. Using ‘complex and simple carbohydrates’ to describe speed of digestion is now defunct because we know many starches are very fast to digest and many sugars are slow.

The anti-sugar message has also soiled the reputation of all carbohydrates, promoting the use of low-carb diets. Besides the obvious nutritional problems of cutting out grains, fruits, dairy and starchy vegetables, new research suggests a ‘spoonful of sugar’ may actually be beneficial for the regeneration of insulin producing beta cells in the pancreas. A mouse study published in Cell Metabolism found the availability of glucose (from the digestion of carbohydrates) increased the speed at which these vital cells reproduce themselves, and may offer hope for people with diabetes whose beta cells have been destroyed or are in decline.

However, this doesn’t give a green light to people with diabetes to stuff themselves with sweets, but it does discredit the sugar veto. Today, the advice for people with diabetes is the same as for the general population: consume moderate amounts of sugars and foods containing added sugars. The caveat if you have diabetes being to spread your carbs evenly through the day, balance carb intake with medication and choose low GI carbs where possible. Sugar is NOT OK when eaten in large quantities and in less nutritious foods such as confectionery and soft drinks. But some sugar is OK when eaten in moderate amounts within healthy foods. For example, in low fat fruit yoghurt, custard or ice cream, or wholegrain or high fibre breakfast cereal – even a small piece of fruit cake or oat biscuit. There is no need to especially restrict the natural sugars found in fruit and dairy foods. There’s more to a diet for diabetes than the sugar content of foods and a little sugar might help make healthy foods more enjoyable and life a little sweeter.

Sorry Nicole, I don't buy it. The whole idea of diabetics being advised to eat sugar "in moderate amounts" because the GI of sucrose is moderate (between 56-69) as rather than high is as harmful as it is ignorant. Just because a particular food converts to glucose more slowly than another doesn't mean it is any less harmful. Research clearly shows that any BG reading over 90 mg/dl causes organ and tissue damage in the body. Try to eat any amount of sugar w/o your blood glucose level going over 90. Go ahead, try it.

And when are we going to get beyond this "dropping BG but still above 90 mg/dl is somehow healthy" nonsense? Why are diabetics told that a BG level of 125 is okay? Or 100? It isn't. And not just from the damage the elevated blood glucose is causing. If BG is above 73-75 mg/dl (the healthy BG level for non-diabetics), then your blood insulin level is also elevated as your body tries to compensate for the insulin resistance present in the body. Where is the discussion on the severely damaging effects of hyperinsulinemia? Obesity. Inflammatory response?

Do you honestly believe that just because someone's BG does go as high as it used to that this is somehow healthy? Do you honestly believe that a diabetic should eat any amount of sugar if their BG is over 90? How do you suppose we are to bring blood insulin levels to normal if BG is elevated? Eating sugar or any carbohydrate, low GI or high GI, will only worsen the grouping of health challenges diabetics face.

I don't think you "busted" any myth here. You only busted your credibility in my opinion.

It would be easier to follow Ken's argument if the BGL readings were translated from the US form (mg/dL) into the one used elsewhere (mmol/L). Could someone do that please?

Is it coincidence that this piece appears shortly after Gary Taubes asks (and answers at length) the question "Is Sugar Toxic?" in the New York Times on April 13? Your readers would be much better served to read (and act on) that article at http://www.nytimes.com/2011/04/17/magazine/mag-17Sugar-t.html?pagewanted=all

It's hard to understand why GI News continues to publish Nicole Senior's nonsense, after earlier comments posted here documented that she is paid by food-business lobby groups.

In response to Daniela, UK regarding the BGL in Ken's comments being in mg/dl instead of mmol/l. All you need to do is put a decimal point in, for example, 125 mg/dl is 12.5 mmol/l, 90 mg/dl is 9.0 mmol/l etc. Hope this helps.
