Pescetarian diets prevail in nutrition study while keto and paleo labeled bad news for climate change

The pescetarian diet was the most nutritious, followed by vegetarian and vegan diets. The omnivore diet came out in the middle, while the least nutritious diets were the ketogenic and paleo diets, which also were responsible for the highest carbon emissions.
