Legumes as a sustainable source of protein in human diets
This article by researchers from the Johns Hopkins Center for a Livable Future argues that more emphasis should be placed on legumes - such as soybeans, peanuts, chickpeas, fava beans, lentils and other beans and peas - as a source of dietary protein, for reduction of greenhouse gas emissions from agriculture, and for their ability to increase soil fertility through atmospheric nitrogen fixation. It reviews trends in legume production and consumption and identifies challenges and limitations to increasing legume use worldwide.
