Consuming an additional daily serving of minimally processed plant-based foods (whole grains, fruits, vegetables, nuts, legumes, olive oil) is associated with significantly reduced risk of mortality and chronic diseases (CHD, diabetes, stroke, colorectal cancer) and has among the lowest environmental impacts.
Add one extra serving of whole grains, fruits, vegetables, nuts, legumes, or olive oil to your daily diet. This simple change is linked to lower risks of heart disease, diabetes, stroke, cancer, and early death, while also being better for the environment. Focus on minimally processed options.
StrongSupportsHIGH confidence
nuts, minimally processed whole grains, fruits, vegetables, legumes, olive oil, and fish are associated with significantly (P < 0.05) reduced mortality and/or reduced risk for one or more diseases... consuming an additional serving per day of these 7 foods is associated with a significant reduction in risk for 20 of the 34 health endpoints... all except fish have among the lowest environmental impacts
