Even modest changes to diet could reduce risk of death, study finds


Fad diets capitalize on our desire for quick results but usually fail in the long run.Now new research adds to the evidence that a more moderate approach can make a lasting difference.A study from the Harvard T.H. Chan School of Public Health finds that improving the quality of diet over time, even with modest changes, may significantly reduce the risk of premature death.Improvements to diet included consuming more whole grains, vegetables, fruits, nuts, and fish and eating less red and processed meats and sugary beverages.“Overall, our findings underscore the benefits of healthy eating patterns including the Mediterranean diet and the DASH diet. Our study indicates that even modest improvements in diet quality could meaningfully influence mortality risk and conversely, worsening diet quality may increase the risk,” lead author Mercedes Sotos-Prieto, who worked on the study while a postdoctoral fellow in the Harvard Chan School department of nutrition and who is currently an assistant professor of nutrition at Ohio University, said in a statement.For the study, published in the New England Journal of Medicine, Sotos-Prieto and her team analyzed data on nearly 74,000 adults over a 12-year period. The researchers assessed the participants’ diet using three different scoring methods: the 2010 Alternate Healthy Eating Index, the Alternate Mediterranean Diet score, and the Dietary Approaches to Stop Hypertension (DASH) diet score. Each model assigns scores to various types of food, with healthier foods receiving higher scores and less healthy foods receiving lower scores.
