Scientists reveal the foods can help you live longer and protect the planet
Known as the Planetary Health Diet Index , it looks at existing evidence to give scores for foods, taking into account the risk of chronic diseases such as heart disease, bowel cancer, diabetes and stroke, as well as environmental impacts such as water use, land use, nutrient pollution and greenhouse gas emissions.
Linh Bui, a PhD student in the Department of Nutrition at Harvard University’s TH Chan School of Public Health, in the US, said: “We proposed a new diet score that incorporates the best current scientific evidence of food effects on both health and the environment. “A sustainable dietary pattern should not only be healthy but also consistent within planetary boundaries for greenhouse gas emissions and other environmental parameters.”
