Diet high in nuts can
protect women against diabetes 
By Dr Narinder Saini
Harvard researchers who studied data on the
eating habits of more than 80,000 women reported
that women who ate five ounces of nuts or more a
week were 30 per cent less likely to develop the
disease than women who rarely or never ate nuts.
It is not clear exactly why the nuts protect against
type-II diabetes. Nuts contain 70 to 80 per cent
fat but most of it is unsaturated (mono or polyunsaturated
fat) which has been shown to be good for insulin
sensitivity and blood cholesterol. On the other
hand, saturated fat and trans-fat are known to adversely
affect glucose metabolism and insulin resistance,
potentially increasing the risk for type-II diabetes.
"To avoid increased calorie intake, people
should not simply add nuts to the diet, instead
people should substitute nuts for less healthy foods
such as refined carbohydrates like white bread and
processed red meats", Rui Jang said, co-author
of the study, and a researcher at the Harvard School
of Public Health
