What are the healthiest diets for a long life?

According to a new study, many healthy eating patterns can help you live longer, as long as those eating habits focus on whole grains, fruits, vegetables, nuts and legumes.

For the study, researchers at Harvard University looked at data from more than 75,000 women and more than 44,000 men who completed a series of dietary questionnaires over 36 years from their early 50s. None of the participants had a history of cancer or heart disease.

The scientists rated their diets based on how well they followed one of four different diets, including a plant-based diet and the Mediterranean diet. The other two diets were the Healthy Eating Index, which aligns with the US Dietary Guidelines for Americans, and the Alternative Healthy Eating Index developed by Harvard, which takes into account the link between what we eat and the risk of chronic disease.

People who followed any of these healthy eating patterns most closely were up to 20% less likely to die from all causes during the study and were also significantly less likely to die from typical causes like cancer, heart disease and respiratory disease, researchers. reported on January 9 at JAMA internal medicine. People from all racial and ethnic groups in the study had a lower risk of premature death when they followed any of these healthy diets.
