Large-scale study identifies eight dietary patterns that contribute to healthy aging
Less than 10% of the 100,000 Americans in the study reached the age of 70 in good health

We tend to use the phrase “you are what you eat” in the present tense, but science suggests we should think of it in the future tense. The diet we follow in middle age largely determines the quality of our old age. While many studies have pointed to this idea, few have had as extensive a database as the one published on Monday in Nature Medicine. The researchers tracked the diets of more than 100,000 Americans for 30 years and then assessed their health at age 70.
