The article discusses a study published in Nature Medicine, which tracked the dietary habits of over 100,000 Americans for 30 years, linking their diets to health outcomes at 70 years old. It found that consuming a diet rich in fruits, vegetables, nuts, and whole grains promotes better mental and physical health in old age, whereas high trans fats and processed foods correlate with worse health outcomes. Surprisingly, only 9.3% of participants aged healthily, highlighting the gap between dietary recommendations and actual adherence. Despite the American context affecting the results, the findings are deemed universally relevant for understanding healthy aging.
The researchers tracked the diets of more than 100,000 Americans for 30 years and then assessed their health at age 70. A diet rich in fruits, vegetables, whole grains, nuts, legumes, and low-fat dairy products was associated with better physical and mental health in old age.
Despite the environments and access to healthcare differences, the study's conclusions about diet's impact on aging are universally applicable, addressing essential biological issues.
