Developed by the EAT-Lancet Commission, the Planetary Health Diet emphasizes vegetables, fruits, whole grains, legumes, and nuts, with smaller amounts of meat, fish, dairy, and eggs. You can think of it as a flexible framework, not a strict meal plan. You don’t have to go vegan, count every serving, or give up favorite foods. The goal is simply to make plant-based eating a bigger part of your everyday meals because, beyond being good for the planet, plant-based foods provide fiber, vitamins, minerals, and other beneficial compounds to support overall health.
