As an added bonus, recent research has found that omega 3 fatty acids may slow down the ageing process. In a recent study which evaluated the blood cells of those who had recently suffered a heart attack, those with higher levels of omega 3 fatty acids also had longer telomeres. Telomeres are little protective bits at the end of chromosomes which prevent them from becoming damaged when they replicate themselves. Eventually, though many replications, telomeres become so short that they cannot function any longer and the cell dies.
