Influence of dietary fat and protein on serum cholesterol of cholesterol‐fed chicks

Abstract

Summary Cottonseed oil, partially hydrogenated cottonseed oil and corn oil, were fed at 4% and 10% of the diets with two levels of protein, 19% and 25%, and with 0.5% cholesterol to cockerels 21 days of age for a period of 38 days. Blood samples were obtained at 0, 14, 24, and 38 daysvia heart puncture. The data indicate that the serum cholesterol value, irrespective of the level or type of fat, was significantly lower in those groups of birds which were fed the higher level of protein. Excluding the combination of 19% protein and 10% cottonseed oil, the degree of saturation did not have any apparent effect upon serum cholesterol because the mean differences among the oils and between the fat levels were not statistically significant.

The Effects of Using Chemicals to Remove Slime from African Giant Land Snails Flesh during Processing on Some Nutritional and Biochemical Parameters

“…The serum total cholesterol level was generally high in all the groups, demonstrating that, it can be influenced by dietary factor [36]. It is known that, plasma cholesterol is affected more by the level of dietary protein than by the type or level of dietary fat, the reason why lipogenesis is generally low in rats fed with high fat and low protein diet but high in a rich protein diet [37][38][39]. The lower the risks factor for CHD, the lower the risk of CHD development [40].…”

Influence of Fats and Choline on Liver and Serum Cholesterol in the Chick

“…Similar results were obtained by Hegsted et al (1960), who clearly demonstrated that fats high in saturated fatty acids promote hypercholesterolemia and that this effect is counteracted by unsaturated fatty acids. Mone et al (1959), on the other hand, concluded that serum cholesterol was not affected in their experiments by increasing the fat from 4 to 10 percent, or by the degree of unsaturation of the fat.…”
