New studies found that Black American women and Chinese women who ate foods high on the glycemic index were at increased risk for developing type 2 diabetes.
Studies also found that eating more cereal fiber may be associated with a reduced risk of type 2 diabetes in black women.
In one study researchers examined data on more than 40,000 black women who filled out a food questionnaire in 1995. Every two years through 2003, the women provided updates about their weight, health and other information.
During those eight years of follow-up, 1,938 of the women developed type 2 diabetes.

In the second study, researchers followed more than 64,000 Chinese women for an average of five years. During the study, 1,608 of the women developed diabetes.

Women who had high glycemic index diets (High consumption of carbohydrates ) and who ate more food staples such as bread, noodles and rice also had an increased risk. For example, those who ate more than 300 grams of rice per day were 78 percent more likely to develop diabetes than those who ate less than 200 grams of rice per day. Women who ate more cereal fiber were less likely to develop diabetes.

Women can reduce their risk of diabetes by eating a diet that is relatively high in cereal fiber.
A simple change from white bread to whole wheat bread will move a person from a low fiber intake category to a moderate intake category, with a corresponding 10 percent reduction in risk.
