Overview

• Researchers identified genetic variants associated with vegetarianism, including genes involved in lipid metabolism and brain function.
• Self-described vegetarians often still consume some animal products, suggesting biological constraints on adhering to the diet.
• Findings could lead to personalized dietary recommendations and improved meat substitutes based on genetic differences.
• Study analyzed genetics of over 5,000 vegetarians compared to over 320,000 meat-eaters.
• Additional research needed to further understand link between genetics and vegetarianism across populations.
