Perhaps you read the December 17, 2008, Washington Post (online) article, “Mediterranean-Style Diet Best for Blood Sugar Control.”
A physician spokeswoman for the American Heart Association is quoted in the story saying that “…the best diet is a Mediterranean-type diet…”
I mention this only because the Canadian study to which she refers is not a test of the Mediterranean diet in people with diabetes.
[Did you know that some people with diabetes are offended if you call them “diabetics”? To call them diabetics defines them by their disease. They’re not diseases, they’re individual humans.]
There are certainly some studies indicating that the traditional Mediterranean diet may be a good one for people with diabetes, and that the Mediterranean diet can prevent type 2 diabetes, but this Canadian study is not one of them.
