Scientists: Reducing caloric intake by 25% may slow aging

A new study has shown that reducing caloric intake by 25% can slow down the aging process in humans. Changing dietary habits can also lead to a significant reduction in the risk of mortality, Bloomberg reports. According to a new study by Columbia University, reducing caloric intake by 25% can slow down the rate of aging in humans. During a randomized controlled trial, one group followed a calorie-restricted diet for two years, while the other group followed a regular diet. Researchers studied the levels of biomarkers in the DNA of the volunteers, which were measured before and after the study and are known to change with age. The results showed that people who followed a calorie-restricted diet experienced a 2-3% slower rate of aging, which according to earlier studies, corresponds to a 10-15% reduction in the risk of mortality. Kalen Ryan, a research scientist at the Butler Columbia Aging Center and co-author of the study, stated that the research team is currently investigating whether changes in dietary habits can affect long-term prospects for healthy aging.
