What Happened To The Vegan Movement? Rich & Simon Hill On The Rise & Fall Of Plant-Based Eating
"It's very hard, impossible to make the argument based on human health alone. When you look at the nutrition science itself, there are a variety of different dietary patterns that lead to great health outcomes. Mediterranean diet, the Mind diet, the DASH diet, vegetarian, vegan, all done in a healthful way with the focus on unprocessed, minimally processed foods, can all be very healthy."
Simon Hill publicly acknowledges that nutrition science does not support claims that plant-exclusive diets are definitively healthier than other dietary patterns. He states the strongest arguments for veganism are ethical and environmental, not health-based, contradicting years of messaging from the plant-based movement that positioned vegan diets as nutritionally superior.

About this episode

Podcast host Rich Roll and nutrition scientist Simon Hill conducted an unflinching autopsy of the plant-based movement's dramatic collapse since its 2020 peak, when Beyond Meat's stock has since plummeted over 99% and cultural enthusiasm has evaporated. The two longtime plant-based advocates admit significant culpability in the movement's failures, with Roll acknowledging he and other influencers misled the public by marketing ultra-processed vegan products as health foods rather than being transparent about their highly processed nature. Hill reveals that many prominent plant-based health advocates were actually animal rights activists using health messaging as a Trojan horse for ethical arguments, creating a fundamental breach of trust when their true motivations became apparent. Both men acknowledge the nutrition science does not support claims that vegan diets are definitively healthier than other whole-food dietary patterns like Mediterranean or DASH diets, admitting the strongest arguments for plant-based eating are ethical and environmental, not health-based. They attribute the movement's failure to three primary factors: lack of honesty about health implications and proper supplementation needs, counterproductive communication strategies including moral superiority and vegan-on-vegan attacks, and cultural shifts post-COVID where plant-based eating became associated with wokeness and attacked by the red-pilled manosphere. Roll specifically admits to reductive messaging that extrapolated his personal success to universal claims without appreciating individual physiological differences. Hill explains Beyond Meat's collapse resulted from failing to achieve price parity (costing 2-3 times more than chicken) or taste equivalence with conventional meat. The conversation pivots to practical advice, with both advocating for eating predominantly whole plant foods while being honest that some individuals may need to include small amounts of animal products, and emphasizing the importance of proper protein intake and supplementation with B12, omega-3s, and potentially other micronutrients.
