Experimental studies and epidemiologic data both indicate that high-fat diets increase the risk of cancer at sites such as breast, colon, and pancreas. Dietary polyunsaturated vegetable oils promote tumorigenesis in animals whereas saturated fats and polyunsaturated fish oils either have little effect or are inhibitory. A blend of fats typical of the American diet enhanced mammary tumorigenesis...

Dietary fats have important effects on the risk of cardiovascular disease (CVD). Abundant evidence shows that partial replacement of saturated fatty acids (SAFA) with unsaturated fatty acids improves the blood lipid and lipoprotein profile and reduces the risk of coronary heart disease (CHD). Low-fat diets high in refined carbohydrates and sugar are not effective. Very long-chain polyunsaturate...

Two hundred eighty days old male broiler chicks(Ross strain) were randomly distributed into seven groups with four replicates (10 birds in each replicate) and were fed diets supplemented with different dietary fat sources.The results indicated that the different dietary treatments did not affect weight gain, feed intake and feed conversion ratio at 21 d (P>0.05). However, addition of dietary fa...

The possibility remains that the kind, rather than the amount of fat in the diet is responsible for atherosclerosis. Much time has been spent in studying vegetarian versus nonvegetarian groups. No critical results have been made available. The reported effect of vegetable fats and their content of unsaturated essential fatty acids is also of extreme interest in this connection. One of the major...

BACKGROUND Gallstones are a highly prevalent condition; however, the nutritional and lifestyle risk factors of this disease are not well understood. OBJECTIVE We evaluated the association between diet, physical activity, and incident cases of gallstones diagnosed by ultrasound in a population-based, case-control study. DESIGN One hundred patients with newly diagnosed gallstones and 290 rand...

Little is known about the effect of preventive diets on colonic nutrient concentrations. This study randomized 120 persons at increased risk of colon cancer to a Mediterranean versus a Healthy Eating diet for six months. The former targeted increases in whole grains, fruits, vegetables, monounsaturated, and n3 fats. The Healthy Eating diet was based on Healthy People 2010 recommendations. At ba...

The prevention and treatment of coronary heart disease (CHD) necessitates vigorous dietary intervention so as to lower the serum cholesterol level by at least 6%. Greater decreases in serum cholesterol can bring about reversal of atherosclerosis. The critical dietary change is the reduction in intake of saturated fat and cholesterol. Some of this fat may be replaced by unsaturated fats, especia...

The most popular way is to evaluate the diet in terms of its metabolizable energy (ME) content measured in kcal ( I kcal=4-184 kJ). The problems associated with the determination of ME have been recently reviewed by Miller (1974). Unfortunately, the ME of a diet is not always equal to the sum of the ME values of its constituent parts (Vohra, 1972). It is reduced by the presence of toxicants, bu...

1The development of food-based dietary guidelines for prevention of cardiovascular diseases requires knowledge of the contribution of common foods to SFA and PUFA intake. We systematically reviewed available data from European countries on population intakes and dietary sources of total fat, SFA, and PUFA. Data from national dietary surveys or population studies published >1995 were searched th...
