![]() “By doing this, we think it will be pretty easy for people to adopt the new dishes, because they will be pretty similar to what they are currently eating.” The beef triple whammy “The key was to find swaps that were culinarily equivalent,” Rose said. They then matched each of these foods to a similar option with a much lower carbon footprint to propose a swap and calculated what the impact would be both for an individual’s carbon footprint and for the country’s if the changes were made. In each of four food groups - protein, mixed dishes, dairy and beverages - they identified foods that disproportionately contribute to greenhouse gas emissions. To identify easy food substitutions that could have an outsized climate impact, the researchers merged data on food-related greenhouse gas emissions with a large, nationally representative survey on what people eat in the United States. 26 in Nature Food, with senior author Diego Rose of the Tulane University School of Public Health and Tropical Medicine. Grummon conducted the investigation, published Oct. ![]() Department of Agriculture’s Healthy Eating Index - which measures how healthy our diets are - and found that the changes stood to improve overall dietary quality for all demographics. The researchers also assessed the health impacts of their suggested changes using the U.S. ![]() “Instead, we’ve identified simple, achievable substitutions - small changes - that can still produce a meaningful impact.” “Many people are concerned about climate change, but sweeping dietary change can be hard,” says the study’s lead author, Anna Grummon, PhD, an assistant professor of pediatrics and health policy. dietary carbon footprint by more than 35%, the researchers found. If universally adopted, such choices would lower the U.S. The suggestions include exchanges as easy as replacing beef with chicken in a burrito or selecting plant-based milk over dairy. Researchers led by the Stanford School of Medicine have identified a set of simple food swaps that can make a big difference in an individual’s carbon footprint - without the need for a drastic dietary overhaul.
