Background: Beneficial effects of omega-3 polyunsaturated fatty acids (PUFAs) on the male fertility are widely described in the literature. However, there is little information about the effect of dietary n-3/n-6 ratios and Vit E on the male reproduction. The aim of this study was to evaluate the influence of dietary PUFAs on the rat sperm characteristics after eight weeks oil consumption. Mate...

Epidemiological evidence suggests that dietary consumption of the long chain omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), commonly found in fish or fish oil, may modify the risk for certain neuropsychiatric disorders. As evidence, decreased blood levels of omega-3 fatty acids have been associated with several neuropsychiatric conditions, including Attention De...

There is substantial evidence that omega-3 fatty acids reduce blood pressure, with a greater effect in hypertensive patients and those with high-normal blood pressure. The dose of omega-3 fatty acids required to achieve a blood pressure reduction is likely to be at least 3-4 g/day. However, the magnitude of the blood pressure change can be increased by salt restriction or when omega-3 fatty aci...

The etiology and treatment of mood disorders has not yet been elucidated. Omega (omega)-3 fatty acids are essential fatty acids, which cannot be synthesized in the human body. Eicosapentanoic acid (EPA) and docosahexaenoic acid (DHA) are representative omega-3 fatty acids which are found in fish (eg., mackerel, herring, Chinook salmon) and vegetables (eg., flax, walnut, canola). The peripheral ...

Omega-3 fatty acids play crucial roles in the development and function of the central nervous system. These components, which must be obtained from dietary sources, have been implicated in a variety of neurodevelopmental and psychiatric disorders. Furthermore, the presence of omega-6 fatty acids may interfere with omega-3 fatty acid metabolism. The present study investigated whether changes in ...

Several sources of information suggest that man evolved on a diet with a ratio of omega 6 to omega 3 fatty acids of approximately 1 whereas today this ratio is approximately 10:1 to 20-25:1, indicating that Western diets are deficient in omega 3 fatty acids compared with the diet on which humans evolved and their genetic patterns were established. Omega-3 fatty acids increase bleeding time; dec...

Transgenic mice (named "Omega mice") were engineered to carry both optimized fat-1 and fat-2 genes from the roundworm Caenorhabditis elegans and are capable of producing essential omega-6 and omega-3 fatty acids from saturated fats or carbohydrates. When maintained on a high-saturated fat diet lacking essential fatty acids or a high-carbohydrate, no-fat diet, the Omega mice exhibit high tissue ...
