The Planetary Health Diet: Why Cutting Meat and Dairy Risks Human Health

The Planetary Health Diet, promoted as a sustainable solution by the EAT-Lancet Commission, allows only minimal animal foods—about one bite of red meat per day and one egg per week. A new clinical trial found sharp nutrient declines in just 12 weeks, including a 36% drop in vitamin B12 and 28% drop in vitamin D. Nutrition expert Nina Teicholz warns this plan risks trading human health for environmental goals, while ignoring regenerative farming solutions that could support both people and the planet.
