Tofu Outranks Beef and Eggs in New Cambridge Protein Sustainability Index
A new 40-point index by the University of Cambridge and the Better Protein Institute ranks tofu as the superior protein source, beating beef, salmon, and eggs. The score balances nutritional value, affordability, and environmental impact, with tofu leading due to low greenhouse gas emissions and land use. While experts note the ranking's limitations, dietitians emphasize that individual needs and serving sizes should guide food choices over strict adherence to such scores.
