Badano wpływ zawartych w diecie zmielonych, pełnych i odtłuszczonych nasion szarłatu (Amaranthus cruentus) na lipidy surowicy krwi i wątroby szczurów. Oznaczano zawartość cholesterolu całkowitego, cholesterolu -HDL, triglicerydów i wolnych kwasów tłuszczowych. Stwierdzono hipocholesterolemiczne działanie nasion szarłatu w surowicy krwi i wątrobie badanych zwierząt oraz hipotriglicerydemiczne w wątrobie.

The effects of milled, whole, and defatted amaranth (Amaranthus cruentus) seeds on serum and liver lipids in rats were studied. In a nutritional experiment, three groups (10 animals each) of rats weighing 200-215 g at the beginning of the experiment were maintained for 28 days on three diets containing-I - casein, II - milled full amaranth seeds, III - milled defatted amaranth seeds. Casein and amaranth seeds contained in the diets supplied about 10% proteins to the animals. Lard (15% of the diet) was the source of fat. At the end of the experiment, total cholesterol, cholesterol-HDL, triglyceride, free fatty acid levels in blood serum, and total cholesterol and triglycerides in liver were determined. Total cholesterol levels in blood serum of rats maintained on the diets containing milled full and defatted amaranth seeds was by 37% and 33%, respectively, lower than in the animals receiving the casein diet. The effect of full amaranth seeds on blood serum cholesterol levels was very similar to that of the degreased seeds. The concentrations of cholesterol-HDL, triglycerides and free fatty acids in blood serum of test animals were similar for all diets, suggesting that the diets did not affect those concentrations significantly. The amount of total cholesterol in liver of rats maintained on diets with amaranth seeds was also significantly (by 41%) lower than that of rats receiving casein. The concentrations of triglycerides were also significantly (by 18% and 25%) lower than in the animals receiving cesein diet. The lowest triglyceride levels were found in the animals fed with the diet containing milled defatted seeds. The removal of the fat from amaranth seeds, however, did not affect cholesterol level in liver of the test animals.
