After monitoring the health data of more than 10,000 people over 50 for 8 years to determine the impact of diet on biological age, researchers from Zhejiang University (China) advise limit meat consumption if you want to age in good shape.
In a study, published in August in BMC medicine, they show that people who follow a “healthy” diet rich in fresh fruits and vegetables and legumes age more slowly than those who consume more animal products and ultra-processed foods. In other words, the vegetarian diet would allow us to have a biological age (the age of our cells) lower than our chronological age (that which corresponds to our date of birth).
How to slow cell aging
Scientists are increasingly interested in biological age, to measure a person’s actual state of fitness and health. They simply observe cells to determine whether they have entered senescence, a phase of cellular development in which they lose the ability to regenerate and repair themselves, paving the way for age-related diseases.
This is what Chinese researchers do. Which allowed them to discover that followers of the vegetarian diet reduced their risk of accelerated aging by around a third… provided they did not opt for refined grains, canned vegetables or dairy products, all identified as “key potential contributors to higher aging scores”.
