The researchers suggested that excessive amounts of carbohydrate-rich foods with a high glycemic index put pressure on the pancreas to produce more of the hormone insulin, which stimulates the body’s cells to take in and store glucose. Over time, the body may become resistant to insulin. IN such insulin-resistant people, the cells become less and less sensitive to insulin. This is characteristic of Type 2 diabetes. Of course, not everyone on such a low-fiber, high-starch diet develops diabetes. These seem to be a genetic predisposition to diabetes, which may be exacerbated by this kind of diet. With out these dietary factors, the men and women in these two studies might have developed diabetes later in life, or perhaps not at all.
