"Linking High-Protein Diets, Leucine, and Artery Plaque: New Study Findings"

High-protein diets, popular in diets like paleo and keto, may be linked to atherosclerosis and cardiovascular disease due to the amino acid leucine, according to a study in Nature Metabolism. The study found that high-protein intake led to increased activation of inflammatory cells, which can cause atherosclerosis. Leucine, predominantly found in animal proteins, was identified as a key culprit. The findings suggest that a balanced diet and considering calorie intake may be important in mitigating potential harm from high-protein diets, and plant-based sources of protein may be a healthier option.
