Revealed by a new study
The researchers emphasized that taking a high daily dose of an omega-3 supplement may also help slow the effects of aging by suppressing damage and enhancing protection at the cellular level during and after a stressful event.
In the study, published in the journal Molecular Psychiatry, participants who took an omega-3 supplement produced fewer amounts of the stress hormone cortisol and lower levels of the inflammatory protein during a stressful event in the laboratory, compared to the group of people who took a placebo.
And while omega-3 levels fell sharply in the placebo group after stress, no such declines were detected in people who took omega-3s.
Omega-3 supplements have contributed to what researchers call stress resistance, which is to reduce damage during and after acute stress, and to protect the components of cells that shrink as a result of aging.
Annelies Madison, lead author of the paper and a graduate student in clinical psychology in Ohio, said: The results indicate that omega-3 supplementation is one of the relatively simple changes that people can make that could have a positive effect in breaking the chain between Stress and its negative health effects.
