ANXIETY OR DEPRESSION CANNOT BE STOPPED BY OMEGA-3 FATS

What is Omega-3?

Omega-3s are a kind of polyunsaturated fatty acids, whose first C = C double bond involves the third carbon (from the opposite side of the acid group). The precursor of omega-3 is α-linolenic acid, that is to say, that from this fatty acid.

There is a strong belief that long-chain omega-3 fats (those derived from fish) prevent and reduce symptoms of depression and anxiety, say the authors of a systematic review of the scientific literature on the subject. , published in November in the British Journal of Psychiatry.

Lee Hooper of the University of East Anglia and his colleagues analyzed the results of 31 randomized trials involving a total of more than 41,470 participants with or without depression or anxiety.

They were randomly assigned to consume more long-chain omega-3 fats (fish oils) or to maintain their usual consumption for at least six months analysis shows that the supplements had little or no effect on preventing symptoms of depression or anxiety.

The research

“Our previous research had already shown that long-chain omega-3 supplements, including fish oils, do not protect against heart disease, stroke, diabetes, or death,” says the researcher. (Cardiovascular Health: Omega-3 Supplements Compared to Placebo in a Large Study)

“The most reliable studies have consistently shown that long-chain omega-3 fatty acids have little or no effect on depression or anxiety, and shouldn’t have promoted as treatment. “

“Oily fish can be a good nutritious food as part of a balanced diet,” says Katherine Deane, co-author. “But we found no value demonstrated in people taking Omega 3 oil supplements to prevent depression and anxiety. “

“Given the environmental concerns of industrial fishing and its impact on fish stocks and plastic pollution in the oceans, it seems useless to continue swallowing fish oil tablets that provide no benefit. “
