I was intrigued by a recent Swedish study reporting that people on a so-called "Stone Age" diet had more stable blood sugar levels than those on a Mediterranean diet. An intriguing claim, because it's so often said that Mediterranean-style eating is super-healthful. Let's also admit it is a delicious way to eat: yes, pasta and bread is there, but it's balanced out by tons of fresh fruits, vegetables, fish and olive oil. The Stone Age way is a bit more spare: we're talkin' meat, fish, and lots of whole grains, berries and nuts. Nary a sliver of Parmesan in sight.

However, the results of yet another study, this time from Australia, indicates Mediterranean-style eating is a good choice, especially for diabetics. Researchers from the University of Melbourne say Mediterranean-born immigrants in Australia are less likely to die from heart disease than other Australians. The researchers have concluded it's all down to dietary patterns. More than forty thousand people participated in the study over a period of ten years. The numbers revealed those who ate the most Mediterranean-style foods had a thirty percent lower risk of dying from heart disease. For diabetics, the researchers speculate, the benefits could be even higher, reducing the risk of death due to ischemic heart disease.

Results have been published in The American Journal of Clinical Nutrition. Visit Reuters for a discussion of the study.

Nutraceutical refers to foods claimed to have a medicinal effect on human health. The American Diabetes Association says individuals at risk of developing diabetes can make changes in their diet and increse their level of physical activity to reduce their risk. The following mentions a few foods and supplements that are your friends in the fight against diabetes.

You've probably heard a million times the benefit of soluble fiber. It lends a big helping hand by slowing carbohydrate absorption. Easy sources of soluble fiber include: oat bran, nuts, barley, flax seed, fruits like oranges and apples, and vegetables like carrots. Another nutritional gem is coffee! Well, more specifically chlorogenic acid, the antioxidant found in coffee. It slows the release of glucose into the bloodstream after a meal. Caffeine counteracts this effect, so diabetics are better off drinking decaf. Barley malt has similar blood glucose lowering effects as metformin, without the side effects. Some say barley malt is to beer as grapes are to wine. Barley malt extract (available in powder and liquid forms) is also used medicinally as a bulking agent to promote bowel regularity.

Other honorable mentions include: magnesium, chromium piccolinate, conjugated linoleic acid, bitter melon and our beloved cinnamon. Nutraceuticals would likely have substantial diabetes-preventive efficacy, and presumably could be marketed legally as aids to good glucose tolerance and insulin sensitivity.
