Plant-Powered Longevity: Science Confirms the Secret to a Longer Life

A groundbreaking global study has revealed that populations consuming more plant-based proteins—such as chickpeas, tofu, and peas—tend to live longer. Researchers analyzed food supply and demographic data from 101 countries over a 60-year period, correcting for wealth and population size, to determine the impact of dietary protein sources on life expectancy.  

 

Key Findings:  

- Countries with higher availability of plant-based proteins, such as India, showed longer adult life expectancies compared to nations with meat-heavy diets like the US  

- While animal-based proteins were linked to lower infant mortality rates, plant-based diets contributed to increased longevity in adults  

- High consumption of processed meat has long been associated with chronic conditions such as cardiovascular disease, type 2 diabetes, and certain cancers  

Lead investigator Dr. Alistair Senior emphasized that as eating habits evolve and countries aim to decarbonize, the source of dietary protein has come under greater scrutiny. The findings reinforce the health benefits of plant-based nutrition, offering valuable insights for individuals and policymakers alike.
