Dietary Effects on Blood Pressure: 1. Effects of Dietary Cholesterol and Fat Sources

Abstract

DAUBER and Katz (1943) and Sutton et al. (1958) found that dietary cholesterol increased serum cholesterol concentrations in chickens. Anderson et al. (1961) reported that hydrogenated oils in the diets of men resulted in a rise in serum cholesterol concentration. However, Diller et al. (1961) fed hydrogenated and unhydrogenated oils to rats and found no apparent correlation between the degree of unsaturation of the oils and plasma cholesterol concentrations. Daghir et al. (1960) found that dietary soybean oil caused a significant decrease in serum cholesterol in laying hens while white grease did not significantly increase serum cholesterol concentrations. Daghir and Balloun (1961) reported that rations containing white grease caused higher serum cholesterol concentrations in chicks than did soybean oil rations or the control ration. No attempts were made, however, to relate serum cholesterol to blood pressure.Since it was postulated that an increase in blood cholesterol over a long period…
