Vegetarian and vegan options have become standard fare in the American diet, from upscale restaurants to fast-food chains. And many people know that the food choices they make affect their own health as well as that of the planet.
Ultimately, we wanted to know: Are drastic dietary changes required to improve our individual health and reduce environmental impacts? And does the entire population need to become vegan to make a meaningful difference for human health and that of the planet? How did we crunch the numbers? We based our Health Nutritional Index on a large epidemiological study called the Global Burden of Disease, a comprehensive global study and database that was developed with the help of more than 7,000 researchers around the world. The Global Burden of Disease determines the risks and benefits associated with multiple environmental, metabolic and behavioral factors – including 15 dietary risk factors.
Like a traffic light, green foods have beneficial effects on health and a low environmental impact and should be increased in the diet, while red foods should be reduced. Foods that people might consider increasing are those that have high beneficial effects on health and low environmental impacts. We observed a lot of flexibility among these “green” choices, including whole grains, fruits, vegetables, nuts, legumes and low-environmental impact fish and seafood. These items also offer options for all income levels, tastes and cultures.
