Although a causal role of genetic alterations in human cancer is well established, it is still unclear whether dietary fat can modulate cancer risk in a predisposed population. Epidemiological studies suggest that diets rich in omega-3 polyunsaturated fatty acids reduce cancer incidence. To determine the influence of fatty acids on prostate cancer risk in animals with a defined genetic lesion, ...
Female rats were given throughout pregnancy and lactation a semi-synthetic diet, in which the fat was provided entirely by a soft margarine rich in linoleic acid (18:2 omega 6) or by mixture of butter and lard, and the influence on the fatty acid composition of fetal and pup brain and retinal phosphoglycerides was studied. The percentage of docosahexaenoic acid (22:6 omega 3) was much lower but...
The ratio of omega-3 to omega-6 fatty acids, especially the long-chain eicosapentaenoic acid (EPA) + docosahexaenoic acid (DHA) to arachidonic acid (AA) ratio, is inversely associated with breast cancer risk. We measured the association between cytologic atypia, a biomarker for short-term risk of breast cancer development, and omega-3 and omega-6 fatty acid intake and levels in blood and breast...
ba ckground: although some studies have shown positive effects of omega-3 fatty acid supplementation on nutritional status of cancer patients undergoing different treatments, there is no consistency in results. the aim of this study was to examine the effects of omega-3 fatty acid on the nutritional status of gastric cancer patients during the course of chemotherapy. m ethods : in a double-blin...
Alarge body of literature suggests that higher intakes of omega-6 (or n-6) polyunsaturated fatty acids (PUFAs) reduce risk for coronary heart disease (CHD). However, for the reasons outlined below, some individuals and groups have recommended substantial reductions in omega-6 PUFA intake.1–4 The purpose of this advisory is to review evidence on the relationship between omega-6 PUFAs and the ris...
BACKGROUND & AIMS Omega 3 and omega 6 polyunsaturated fatty acids have been related to many diseases, especially to cardiovascular diseases. We aimed to assess the association between the intake of omega 3, omega 6 fatty acids and their ratio and the incidence of glaucoma in this prospective cohort study. METHODS We followed-up 17,128 participants initially free of glaucoma for a median time ...
Cardiovascular diseases and cancers are leading causes of morbidity and mortality. Reducing dietary saturated fat and replacing it with polyunsaturated fat is still the main dietary strategy to prevent cardiovascular diseases, although major flaws have been reported in the analyses supporting this approach. Recent studies introducing the concept of myocardial preconditioning have opened new ave...
Strategic in pathophysiological homeostasis (following injury), as well as cellular, tissue and organismic protection are acute and chronic inflammatory responses [1,2]. Consequently, the pathogenesis and progression of cardiovascular and other diseases is initiated and perpetuated by this phenomenon. Efforts to normalize or control inflammatory processes include pharmacological, dietary and be...
