Higher Dietary Selenium Intakes Linked To Younger ‘Biological Age’

This study adds to the growing scientific evidence linking higher intakes of selenium with longer telomeres. In particular its findings are consistent with research published in 2020 which indicated that an increased dietary selenium intake is associated with longer telomere length among middle-aged and older adults in America.

Often likened to the tips at the ends of shoelaces without which the laces would unravel, telomeres are found at the ends of chromosomes. Their roles include helping to protect chromosomes from damage and ensuring they are able to replicate properly. Telomeres are known to shorten with age. Research suggests short telomeres may be associated with the development of disease. The consumption of ultra-processed food has been linked to the shortening of telomeres, thus further indicating that diet and nutrition play a key role in protecting them from damage.

As important as selenium is, however, the findings of this latest study should not be interpreted as meaning that a high intake of selenium alone is enough to protect you from aging and disease. Instead, for optimum results, carefully balanced intakes of a wide range of micronutrients are needed.
