We investigated the effect of diets rich in omega-6 and omega-3 fatty acids on hepatic metabolism. ⋯ These results indicated that an enrichment of the diet with omega-3 polyunsaturated fatty acids produces hypolipidemia but may cause changes in liver metabolism that favor lipid deposition. They also suggested that the addition of a small amount of eicosapentaenoic and docosahexaenoic polyunsaturated fatty acids to an omega-6-rich diet further improve the circulating lipid profile, in comparison with an omega-3-rich diet, but it does not prevent excess liver lipid accumulation.

Allium species such as onions and garlic are used as foodstuff, condiment, flavoring, and folk medicine. Onions may decrease hyperlipidemia and improve atherosclerosis. However, the ingredients in onion that are responsible for this phenomenon are not known. ⋯ Hepatic lipid levels were comparable among the groups, although TAG and phospholipid contents were slightly higher in both cycloalliin groups. Dietary cycloalliin had no significant effect on hepatic enzyme activities responsible for TAG synthesis (phosphatidate phosphohydrolase, malic enzyme, and glucose-6-phosphate dehydrogenase (G6PDH)). In conclusion, dietary cycloalliin has serum TG-lowering effect without affecting hepatic TAG synthesis and content in rats, suggesting an alteration of lipoprotein assembly and secretion processes in the liver.

We previously showed that prior oral supplementation of oils rich in omega-3, eicosapentaenoic acid and docosahexaenoic acid, and omega-6, gamma-linolenic acid and arachidonic acid, can prevent the development of alloxan-induced diabetes mellitus in experimental animals. But the effect of individual fatty acids on chemically induced diabetes mellitus is not known. We report the results of our studies with omega-6 fatty acids. ⋯ These results suggest that polyunsaturated fatty acids can prevent chemically induced diabetes in experimental animals and attenuate the oxidant stress that occurs in diabetes mellitus.
