31 Jul 2024 --- A new study found that women following a diet rich in vitamins and minerals with low added sugar had a lower biological age. Moreover, even when people follow healthy diets, the researchers found that each gram of added sugar consumed was associated with a higher biological age. The researchers at the University of California (UC) in San Francisco, US, examined the impact of different healthy diets on participants’ epigenetic clocks, a biochemical test that approximates health and lifespan.
