A new study suggests we might be able to shave years off of our biological clocks with our diet and lifestyles. In a recent study published in the journal Aging, researchers put 43 healthy adult males between the ages of 50 and 72 through a treatment program aimed at optimizing what’s called DNA methylation. The program involved diet, sleep, exercise, relaxation guidance, and supplemental probiotics and phytonutrients. In just eight weeks, the men who performed those treatments reduced their biological age by more than three years compared to men in the control group. While exercise, healthy diets, efforts to manage stress, and better sleep can help us avoid a number of health issues, this study suggests it might make us feel younger too.
