Acute dietary effects on diurnal plasma lipids in normal subjects.
The effects of different dietary carbohydrates and different dietary fats as well as of differently spaced dietary constituents on 24-h plasma free fatty acids and triglycerides were determined in healthy young males. If, in an isocaloric diet containing 15-20% protein, 37% fat and 43--48% carbohydrates, sucrose is compared with glucose, 24-h plasma triglycerides are significantly higher with the former carbohydrate. When palm oil (mainly 16 : 0 fatty acids) is compared with olive oil (mainly 18 : 1 fatty acids), 24-h triglycerides are significantly higher with the latter. If the carbohydrate component of a mixed meal is removed, alimentary lipemia is considerably greater. Our findings supplement long term studies regarding the effect of different dietary fats and carbohydrates on plasma lipids and allow calculation of "upper normal limits" for 24-h plasma triglycerides and free fatty acid patterns on isocaloric diets of "prudent" composition.
