The effect of dietary protein source on serum lipids: Secondary data analysis from a randomized clinical trial


The role a plant-based diet plays in lowering serum lipids levels was investigated in a recent study.? The measurement of serum lipids, such as total cholesterol (TC), low-density lipoprotein (LDL), and high-density lipoprotein (HDL), is used to monitor human health, specifically as a biomarker for cardiovascular disease.? This clinical trial split up 173 post-menopausal women into four groups, each asked to eat an equivalent amount of protein from different food sources; nondairy animal, dairy, non-soy plant, or soy foods.? The women that ate either soy or plant-based diets had a significant decrease in cholesterol, LDL, and HDL, compared to the women whose protein sources came from dairy and non-dairy foods.? Adding soy and plant protein sources into your diet could reduce the risk for heart-related issues, particularly for post-menopausal women.
