A long-term analysis of UK Biobank data showed that following one of the five diets was associated with a lower risk of death and longer life expectancy. Greater adherence to these diets adds more years to life. One large observational study followed 75,230 women from the Nurses' Health Study and 44,085 men from the Health Professionals Follow-up Study for 36 years. Participants were assessed according to their adherence to four healthy eating patterns: Healthy Eating Index 2015, Alternate Mediterranean Diet (AMED), Healthful Plant-based Diet Index, and Alternate Healthy Eating Index (AHEI). Those with the highest scores had a 14% to 20% lower risk of dying from any cause than those with the lowest scores. Additionally, they had a 6% to 15% lower risk of dying from cardiovascular disease, a 7% to 18% lower risk of dying from cancer, and a 35% to 46% lower risk of dying from respiratory disease. The highest scores in AMED and AHEI conferred a slightly lower risk of death from neurodegenerative diseases.[2]
