Effect of Soybean Sterols in the Diet on Plasma and Liver Cholesterol in Chicks

Evidence is presented that the addition to the chicks'diet of mixed soybean sterols and of purified sitosterols in the presence of cottonseed oil and cholesterol causes markedly lower plasma and liver levels of cholesterol than the addition to the diet of a mixture of cholesterol and cottonseed oil alone. The possibility is discussed that one or more of the constituents of the mixed soybean sterols interferes with the absorption of cholesterol.
