The healthiest diet is the Mediterranean and has the smallest carbon footprint. This information is known because researchers have been studying a way to alleviate the growing pollution caused by food consumption. The daily carbon footprint for the Mediterranean diet is 5.08 kg of CO2 vs 8.5-8.5 kg of CO2 for the US diet. The study was created from the carbon footprint of the foods that are grown for each diet. The difference between the diets is because the Mediterranean diet contains less meat.
