Healthy eating in 40s linked to better well-being in 70s: Harvard study

Washington: A recent Harvard study has found that dietary choices made in the 40s can have a significant impact on health and quality of life in the 70s. The research, published in Nature Medicine, emphasises the role of a balanced and nutritious diet in preventing chronic diseases and promoting overall well-being in later years.

The study defines healthy ageing as reaching 70 without major chronic illnesses such as cancer, heart disease, diabetes, or cognitive decline while maintaining physical independence and a good quality of life.

Researchers monitored the eating habits of 105,015 individuals over three decades, evaluating their diets based on eight recognised healthy eating guidelines. The Alternative Healthy Eating Index (AHEI), developed by Harvard, was identified as the most effective diet for promoting healthy ageing. This diet emphasises the consumption of fruits, vegetables, whole grains, nuts, legumes, and healthy fats found in olive oil and fatty fish while discouraging red and processed meats, sugary beverages, refined grains, and high sodium intake.

Experts suggest that while no single diet suits everyone, incorporating nutrient-rich foods, opting for whole grains, and prioritising healthy fats over trans and saturated fats can contribute to better health as individuals age.
