At the ends of chromosomes are telomeres, which are like "protectors" that prevent their disintegration. When we age, they reduce their length, which leads to cell death.
Cells have a life cycle, and telomeres cause them to die faster or, on the contrary, to have a longer life. Stress, recurrent infections and chronic degenerative diseases, such as obesity, contribute to the progressive extinction of cells.
Recent research has found that the "shortening" of telomeres may be delayed, which would slow down aging. The enzyme called "telomerase" causes telomeres to maintain their initial length longer.
The foods that can contribute to this are krill oil, magnesium, blackberries, lentils, spinach and grains in general.
