Abstract:The effects of feeding graded levels of cocoa butter (0, 10, 20, and 30%) in a semi-purified diet to weanling male and female rats for 90 days were evaluated. Serum cholesterol concentrations determined at days 0, 30, 60, and 90 demonstrated significant decreases (P≤0.05) for all cocoa butter treated male rats at day 60. Consumption of cocoa butter containing diets did not have a deleterious effect on the normal growth of Sprague-Dawley rats. Histological evaluations of selected tissues at the termination of the study indicated no pathological abnormalities due to the consumption of cocoa butter.
