Greenhouse gas emissions associated with dietary guidelines vary between countries

Greenhouse gas emissions associated with national dietary guidelines advocating a healthy diet vary greatly between countries, with US guidelines having the largest carbon footprint and India having the smallest, according to a study involving seven countries published in the open access Nutrition Journal. The variations result from differences in recommendations for and consumptions of individual foods within the six main food groups—protein foods, dairy, grains, fruits, vegetables, and oils/fats.
