Our DNA, the carrier of hereditary information in our cells, is constantly subjected to damage. Fortunately, most of this damage is repaired quickly. Even so, a small amount of damage remains, which accumulates over the years. This can contribute to the development of age-related health problems. Scientists are therefore interested in ways to limit this damage.
A striking finding of recent research is that reducing the number of calories in the diet can help slow down the accumulation of harmful changes in DNA. Calorie restriction means eating less than normal while still getting all the necessary nutrients. This not only affects DNA damage, but also improves the function and health of cells in multiple ways.
Although the benefits of calorie restriction are still being extensively studied, it appears that this method can slow down the ageing process by better protecting the cells. As a result, age-related conditions may potentially occur later and less severely. The effect is not only due to reduced DNA damage, but also to healthy changes in the body brought about by calorie restriction.
For people interested in healthy ageing, being mindful of their diet can therefore make a positive contribution. Eating fewer calories, without suffering from nutritional deficiencies, can keep healthy cells functioning for longer and thus contribute to a better quality of life in later years.
