Effect of unsaturated fats and cholesterol on serum and fecal liquids
1979
Hill, P. | Reddy, B.S. | Wynder, E.L.
The effects of diets containing customary foods, supplemented with either sunflower, corn, or soybean oil and margarine, on the serum lipids and acidic and neutral sterols were studied in 60 middle-aged, healthy men and their wives. Modification of the diet, with an intake of 2,500 kcal per day and a decrease in cholesterol and fat intake to 33% of calories, failed to alter serum lipids significantly. When the fatty acid composition and the polyunsaturated/saturated ratio of dietary fat were adjusted, lower serum lipids and a compensatory increase in fecal sterols occurred with the addition of cholesterol to the diet. Changes in serum lipoproteins in the subjects fed a "prudent" or a common diet indicated an increase in the proportion of high density lipoprotein cholesterol which may be beneficial in reducing coronary heart disease.
