Higher Levels of Omega-3’s Associated with Less DNA Damage
DNA damage is an alteration in the chemical structure of DNA that can cause cellular injury. Unrepaired DNA damages accumulate in non-replicating cells, such as cells in the brains or muscles, and can cause aging and certain diseases. A recent study suggests that higher levels of omega-3’s are associated with a lower incidence of DNA damage.
One hundred and forty children with an average age of 11.5 participated in the study. The researchers used blood samples to measure blood concentrations of vitamins and polyunsaturated fatty acids, and to assess DNA damage.
Higher blood levels of EPA and DHA omega-3 fatty acids were associated with lower levels of DNA damage. No relationship was found for retinol, beta-carotene, or riboflavin.
The study was conducted by researchers from the University of Sao Paulo. It was published online ahead of print on April 25, 2020 in the journal Food & Function.
