PALEO DIET

Study of popular diets finds over fourfold difference in carbon footprints

On the other end of the spectrum, a vegan diet was found to be the least impactful on climate, generating 0.7 kg of carbon dioxide per 1,000 calories consumed, less than a quarter of the impact of the keto diet. The vegan diet was followed by vegetarian and pescatarian diets in increasing impact. The pescatarian diet scored highest on the nutritional quality of the diets analyzed, with vegetarian and vegan diets following behind.
