Biological Age Reversed with Diet, Lifestyle
An 8 – week diet and lifestyle treatment that measures DNA methylation age (DNAmAge test) was given to 18 men, aged 50 to 72. The diet was a plant-based, low carbohydrate diet with limited animal proteins. The diet was supplemented with a vegetable and fruit powder and a probiotic.
The lifestyle group was advised to do a minimum of 30 minutes of physical exercise daily and to perform breathing exercises twice daily to reduce stress.
Note: DNA methylation is a chemical reaction that takes place when a methyl group attaches to DNA, changing the expression of a gene to which it is attached. The DNAmage test is considered the most accurate method to assess whether an intervention (s) is slowing or reversing biological aging.
The healthy diet/lifestyle group had scores averaging 1.96 years younger at the end of the program than at the beginning, while control participants averaged 1.27 years older at the end. It was not reported what treatment if any was given to the control group. The difference between the healthy diet/lifestyle group and the controls was 3.23 biological years. The results showed us that diet and other lifestyle factors (exercise, stress reduction) can affect human health and lifespan. This supports the science of epigenetics and that nature and nurture interact to affect many aspects of our lives.
