This Harvard-backed diet makes you more than twice as likely to be healthy at 75

In 2025, the debate over the best diet continues, with individual goals influencing choices. A significant study found that adherence to the Alternative Healthy Eating Index (AHEI) significantly increased health chances in older adults. Those engaging with the AHEI were shown to have an 86% increase in healthy living by age 70 and were over twice as likely to be free from chronic diseases by 75. The AHEI promotes healthy fats, fruits, and vegetables while reducing red meats, reflecting a focus on disease prevention over mere adherence to basic dietary guidelines.

The AHEI, developed by Harvard researchers, emphasizes healthy fats, nuts, legumes, fruits, and whole grains, promoting lower intakes of red and processed meats.

In a study of over 105,000 participants, those adhering to the AHEI were 86% more likely to remain healthy at 70 and twice as likely to be disease-free at 75.
