not to hijack but i found his interesting as well. this article was done in 2005 though.



The GI’s an idea that’s been around in the scientific community for more than 20 years. There’s a solid body of research behind its value for people with diabetes. Nevertheless, there’s not yet conclusive evidence for some of the other health benefits that have been claimed to stem from following a low-GI diet. The GI concept is still very much ‘work in progress’ and some health authorities, particularly in the US, are wary of embracing it.

The suggestion that low-GI diets can help us lose weight and keep it off is based on the argument that the faster we digest our food, the sooner we’re hungry again and the more we tend to eat. While this seems plausible, there’s in fact little evidence to support the idea.

Certainly some low-GI foods are very filling and delay the onset of hunger pangs for many hours. But so does potato, and that has a very high GI. Some small studies have found that people eating low-GI diets lose more weight or body fat than those eating high-GI diets with the same kilojoules; but other studies have found no differences.

The evidence is promising but inconclusive in connection with GI and heart disease. It’s been suggested that the high blood glucose and insulin levels that result from eating a high-GI diet may increase the risk of heart disease via insulin resistance, one of a cluster of metabolic abnormalities that make up the so-called metabolic syndrome (or Syndrome X). These abnormalities also include high blood levels of insulin, glucose and triglycerides, low levels of HDL (good) cholesterol and high blood pressure.

Some studies have found a small reduction in heart disease risk in people eating low-GI diets, but others have reported no significant benefits. Until there’s stronger evidence that the GI of foods has an effect on your health, there’s not much point fussing about it in your diet unless you have diabetes.
