Tofu Beats Meat, Eggs, Fish as World's Best Protein, Science Says

A new study from a Cambridge scientist has determined that tofu is the best overall protein source in terms of health, accessibility, and environmental factors. The study introduced the Better Protein Institute (BPI) Score, which ranked 20 different plant-based and animal-based foods based on their impact on the planet and people. Tofu, chia seeds, beans, and quinoa emerged as the top four proteins, all plant-based, while animal-based proteins like cheddar cheese ranked at the bottom.

The BPI Score aims to provide a more multidimensional approach to looking at protein, considering factors like greenhouse gas emissions, water pollution, nutrition, affordability, and availability. The study encourages consumers to consider the wider impacts of their protein choices on animals, the planet, and future generations. With the rise of plant-based diets and increasing concerns about sustainability, tofu's position as the top protein source highlights the shift towards more environmentally friendly and ethical protein options.
