Overview

  • A 30-year study of over 105,000 health professionals found the Alternative Healthy Eating Index (AHEI) diet most strongly associated with reaching age 70 free of chronic diseases while maintaining cognitive, physical, and mental health.
  • The AHEI diet prioritizes fruits, vegetables, whole grains, nuts, legumes, and healthy fats, while limiting red and processed meats, sugar-sweetened beverages, sodium, and refined grains.
  • Only 9.3% of study participants achieved 'healthy aging,' but those adhering most closely to the AHEI diet were 86% more likely to age healthfully compared to those with the lowest adherence.
  • The study also highlighted the negative impact of ultra-processed foods, such as sugary beverages and processed meats, on aging outcomes.
  • Researchers emphasized the adaptability of healthy diets to individual needs and preferences, while noting limitations in generalizability due to the study's focus on health professionals.
