2001 AUG 9 - (NewsRx Network) -- by Carol K Kohn, MS, ELS(D), senior medical writer Switching from dietary trans fatty acids to nonhydrogenated polyunsaturated fats can substantially reduce the risk of developing type 2 diabetes, say U.S. researchers.
F. Salmeron and colleagues from the Harvard University School of Public Health, Boston, Massachusetts, designed a prospective study to clarify the relationship between fat intake and the risk of diabetes in women.
The researchers obtained baseline dietary information in 1980 from 84,204 women (ages 34-5 9 years) who did not have diabetes, cardiovascular disease, or cancer. Subjects updated their information by filling out questionnaires three times during the study period - in 1984, 1986, and 1990. Risk of developing type 2 diabetes was statistically determined with adjustments made for other dietary and nondietary factors ("Dietary fat intake and risk of type 2 diabetes in women," American Journal of Clinical Nutrition, 2001;73(6): 1019-1026).
Salmeron and coworkers followed the cohort for 14 years and saw 2,507 incident cases of diabetes during that time. However, they did not find that total fat intake, versus the same carbohydrate energy intake, increased diabetes risk (relative risk = 0.98, 95% CI: 0.94, 1.02, for 5% increase in total energy from fat). Likewise, there was no diabetes link with saturated or monounsaturated fats, and polyunsaturated fat showed ...
