Studies on lipids metabolism in rats; 1 dietary protein sources and lipids profiles of rats

ABSTRACT

Protein diets containing either animal protein [skim milk, meat, egg albumin and casein] or plant protein [broad beans, lupinus termis, lentils and soybean] were fed to eight groups of rats for eight weeks. Levels of total cholesterol, HDL-cholesterol, triglycerides and phospholipids as well as weight gain, food intake, protein efficiency were measured. The results showed a significant increase in total lipids, phospholipids, triglycerides and cholesterol and decreasing levels for HDL-cholesterol in the rats fed the animal proteins. However, plant proteins indicated a significant decrease for total lipids, phospholipids, triglycerides and total cholesterol with exception of HDL and cholesterol, which showed increasing level
