Fats
The excessive use of fats has been linked to development of diabetes. A recent study at the University of Colorado Health Science Center, USA found that intake of an extra 40g of fat day increases the chances of developing diabetes by three times. Fat rich diet, especially one saturated with animal fat, seems to damage the insulins effectiveness. Research at the University of Sydney in Australia measured the saturated fatty acids in the muscles cells of older non-diabetic men and the women undergoing surgery and found that higher the presence of saturated fatty acids in the cells, the greater the insulin resistance. On the other hand, higher tissue levels of polyunsaturated fats, particularly fish oil, indicated better insulin activity and lower resistance. Fish oil differs from animal fats in that fish oil contains polyunsaturated fatty acids. One of the fatty acids called omega-3 is especially good for the heartit lowers cholesterol and protects from atherosclerosis. In fact, the researchers also reported that intake of omega-3 fish oil to the subjects effectively overcame their insulin resistance.
