Effects of the Marine Unicellular AlgaNannochloropsissp. to Reduce the Plasma and Liver Cholesterol Levels in Male Rats Fed on Diets with Cholesterol

The effects of Nannochloropsis were studied on rats consuming hypercholesterolemic diets. The whole biomass and the hexane/ethanol extract increased the plasma and hepatic eicosapentaenoic and docosahexaenoic acids levels, and reduced the cholesterol levels. We also observed a higher level of propionate, and a lower ratio between acetate and propionate. These data suggest the efficacy of Nannochloropsis in reducing cholesterol levels.
