Most Americans Still Believe Animal Protein is Essential Despite Scientific Evidence

A recent survey by the Physicians Committee for Responsible Medicine found that 87% of US adults believe consuming animal products is essential for getting enough protein. Despite this, there is a mix of beliefs about the adequacy of plant-based protein sources, with 57% of respondents believing it is possible to build muscle on a plant-based diet. Demographic variations show that women, Gen Z adults, Black adults, and Millennials are more likely to believe in the benefits of a plant-based diet, while Republicans, men, and Baby Boomers are more skeptical.

Research indicates that plant-based protein can be as effective as animal protein for muscle maintenance and growth. Dr. Roxanne Becker of PCRM emphasizes the importance of consuming enough protein, especially as we age, to maintain muscle mass and prevent frailty. She recommends plant protein sources, which are free of cholesterol and low in saturated fat, as the preferred option for meeting protein needs and supporting muscle health.
