Popular Myth Debunked; Omega 3 Doesn’t Help with Anxiety: Study
Increased consumption of omega-3 fats is widely promoted globally - and one of the reasons is the common belief that it will protect against conditions such as anxiety and depression. But researchers have found that fish oil supplements have little or no effect on such conditions.
Omega-3 is a type of fat. Small amounts are essential for good health and can be found in the food that we eat including nuts and seeds and fatty fish, such as salmon.
They are also readily available as over-the-counter supplements and are widely bought and used.
The study, published in the British Journal of Psychiatry, found that omega-3 supplements offer no benefit.
"This large systematic review included information from many thousands of people over long periods," said study lead author Lee Hooper, from University of East Anglia in UK.
For the findings, the research team looked at 31 trials of adults with and without depression or anxiety.
More than 41,470 participants were randomised to consume more long-chain omega-3 fats (fish oils), or maintain their usual intake, for at least six months.
The study found that the supplements had little or no effect in preventing depression or anxiety symptoms.
"Oily fish can be a very nutritious food as part of a balanced diet but we found that there is no demonstrable value in people taking omega-3 oil supplements for the prevention or treatment of depression and anxiety," said study researcher Katherine Deane.
