Instead of avoiding fats it probably makes a lot more sense to eat less carbo.
Eating foods high on the glycemic index, which measures the effect of carbohydrates on blood glucose levels, may be associated with the risk for developing type 2 diabetes in Chinese women and in African-American women, according to two studies in the November 26 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. However, eating more cereal fiber may be associated with a reduced risk for type 2 diabetes in African-American women.
Researchers remain uncertain regarding exactly how diet, including carbohydrate intake, affects the development of type 2 diabetes, according to background information in the articles. Studies have revealed that the body absorbs carbohydrates from different foods at different rates. This leads to varying effects on levels of blood glucose and the hormone insulin, which converts glucose into energy. Foods high on the glycemic index, such as rice and other simple carbohydrates, cause a rapid spike and then a drop in blood glucose, whereas high-fiber foods tend to be lower on the glycemic index and have a more gradual effect. Some evidence has linked high–glycemic index foods with the risk of developing type 2 diabetes.In one study, Supriya Krishnan, D.Sc., of Boston University School of Public Health, and colleagues examined data from 40,078 U.S. black women who filled out a food questionnaire in 1995. The glycemic index and glycemic load—a measure of the amount of carbohydrates from glucose—were calculated. Every two years through 2003, the women answered follow-up questionnaires about their weight, health and other factors.
A high carbohydrate diet with high glycemic index foods almost doubled the risk of type 2 insulin resistant diabetes.
During the study, 1,608 of the women developed diabetes. Women who consumed more carbohydrates overall were more likely to develop diabetes—when they were split into five groups based on carbohydrate intake, those in the group consuming the most (about 337.6 grams per day) had a 28 percent higher risk than those in the group consuming the least (about 263.5 grams per day). Women who ate diets with a higher glycemic index and who ate more staples such as bread, noodles and rice specifically also had an increased risk. Women who ate 300 grams or more of rice per day were 78 percent more likely to develop diabetes than those who ate less than 200 grams per day.
Chinese women who eat more rice are at higher risk of type 2 diabetes mellitus. Cut way back on grains consumption. If you eat grains then at least eat whole grains. Also, pasta is lower in glycemic index than bread. Check out this long list of foods and their glycemic index values. Shift toward beans and away from grains. Eat more fruits and vegetables and nuts.
