Risky Benefits and Beneficial Risks of Animal Protein

Protein is a vital macronutrient essential for overall health, contributing to weight management, improved cardiometabolic health, and regulation of blood glucose levels, fat-free mass, and waist circumference. While animal proteins are a major dietary source, concerns have emerged linking high intake to increased risks of mortality, cancer, and cardiovascular diseases; though findings remain inconsistent and inconclusive. This review seeks to examine the key distinctions between plant and animal protein sources and critically evaluate the health implications of animal protein consumption. It also highlights current knowledge gaps and outlines future research priorities regarding the benefits and potential limitations of animal protein.
