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.

Yes, whole foods are good for your health. But maybe even better than you imagined. A Swedish study has concluded that a "Stone Age" diet is great for the health and could even prevent Type 2 diabetes. So what did people eat in the dark depths of prehistory? Well, a variety of foods, but nearly all of it was high in fiber, low in fat, fresh, and nearly unprocessed.

Scientists took a small group of fourteen glucose intolerant heart patients and put them on the diet of a lifetime: lean meat, fish, fruits, vegetables and nuts. This, it is assumed, is the sort of diet consumed by our Stone Age ancestors - hunter gatherers who lived around 70,000 years ago, long before the emergence of agriculture. Meanwhile, another group of patients with similar health issues were put on a supposedly healthy "Mediterranean diet" rich in whole grains, dairy, fruits and vegies, and unsaturated fats. Well, you guessed it. After twelve weeks, the researchers found those on the Stone Age diet had much more stable blood sugar levels and were better able to process carbohydrates without such major blood sugar fluctuations. In fact, all the Stone Age patients had normal blood glucose levels by the end of the study and also dropped a few pounds too. Those on the Mediterranean diet, however, experienced hardly any changes at all.

Admittedly, this is a very small-scale study. But the results are interesting nevertheless, and, I'd wager, not a huge shock to well-informed diabetics who understand the importance of curbing carb intake for better health. On the other hand, I was interested to note that the author of the study, Dr. Staffan Lindeberg, played down the "carb as culprit" angle, and instead emphasized the following simple rule for better health: avoid modern, processed foods.

A Swedish study has found that elevated blood sugar in women is linked with increased risk of developing cancer.

Researchers identified 2,478 incident cases of cancer from records of 33,293 women and 31,304 men who participated in the study. Participants were recruited in the mid-1980s at age 40, 50 and 60 and the study covered a 13-year period. The records included levels of glucose in the blood when fasting and after receiving an infusion of glucose. Researchers calculated the cancer risk relative to blood glucose while adjusting for: age, year of enrollment, fasting time and smoking status. Women with blood sugar levels higher than normal have a total higher risk for cancer while for men the risk was unchanged at higher blood sugar levels. The overall risk of developing cancer for women in the top 25% of fasting blood glucose levels was 26% higher than those in the bottom 25%. Women with high fasting glucose levels had a higher risk of pancreatic, breast and endometrial cancers, while the increase in risk for malignant melanoma was two times higher.

While previous studies have shown that cancer risk for some cancers is higher for people with type 2 diabetes, this study suggests that something could be happening to trigger cancer much earlier, as glucose levels begin to rise. The scientists also found that the blood sugar levels gradually rose over the period of the study, which they suggest means that cancer risks would also continue to rise unless glucose levels were brought down by some means. The results were no different when they took Body Mass Index (BMI) into account.

The study provides further evidence for an association between abnormal glucose metabolism and cancer. If you ask me - I think this has to do with the pH levels of the blood. It is well known that cancer manifests in blood levels of higher acidity. Poor diabetic control can result in higher acid levels in the blood. The catch 22 is poor diabetic control leaves your entire blood chemistry off kilter and it cannot defend any rogue cells - especially those associated with malignant growth (i.e. cancer!)
