摘要:

A protective effect of habitual fish consumption on the development of impaired glucose tolerance and diabetes is once again suggested in a recent trial. In nondiabetic individuals with essential hypertension, a group known to be insulin resistant, fish oil was not associated with a negative impact on glycemic control, insulin secretion or peripheral insulin sensitivity, even in a subgroup who had impaired glucose tolerance. Furthermore, more recent, long term, placebo-controlled trials in type II patients have failed to demonstrate a significant impact of fish oil supplementation on glycemic control. Additional information is available regarding qualitative changes in VLDL- and LDL-lipoproteins in type II diabetes patients in response to dietary fish oil supplementation. The impact of fish oil on LDL oxidation is the focus of two recent trials. Vitamin E supplementation may mitigate much of the enhanced oxidation of LDL that is potentially seen with dietary fish oil supplementation.

摘要:

The development of the visual system of human infants is dependent in part on the availability of docosahexaenoic acid. The effect is most apparent in preterm infants, suggesting that an exogenous source of docosahexaenoic acid may be needed during the time of rapid development of the retina.

摘要:

Compared with a diet high in total and saturated fat, a high carbohydrate diet improves insulin sensitivity and lipid levels. Recent studies have shown that subjects on an ad-lib low fat, high carbohydrate diet lose weight and, therefore, may have even greater improvement in the metabolic disturbances of the insulin resistance syndrome.

摘要:

Syndrome X refers to a cluster of abnormalities, associated with resistance to insulin-mediated glucose uptake, that increase risk of coronary heart disease. Increases in carbohydrate intake (with reciprocal decreases in fat content) within the boundaries of menus that can be followed in the free-living state have not been shown to decrease insulin resistance, either directly by enhancing insulin sensitivity or indirectly by producing and maintaining weight loss. However, such diets accentuate the metabolic abnormalities that constitute syndrome X. Because substitution of monounsaturated or polyunsaturated fat, or both, for saturated fat results in the same fall in LDL-cholesterol concentration as seen with low fat/high carbohydrate diets, it is concluded that low fat/high carbohydrate diets should be avoided in the treatment of syndrome X.
