The Better Protein Institute scored 20 high-protein foods against both sustainability and health — emissions, water use, land use, sodium, saturated fat, cost, and availability. Tofu topped the combined ranking with 36 points. Cheddar came last with 13.
Every protein in the top 20% was plant-based: tofu, chia seeds, beans, and quinoa. Every protein in the bottom 20% was animal-based: mozzarella, lamb, beef, and cheddar. The gap wasn't close.
The full scoring is published in Frontiers in Sustainable Food Systems.

Plant-based proteins blow animal sources out of the water on sustainability and health metrics, with tofu leading the charts, according to the Better Protein Institute.
