Heart disease risk and blood pressure could be cut by 'optimal' salmon serving

Heart health may be improved by a specific daily dose of fatty acids found in certain fish, a new study suggests. Researchers say a daily helping of fatty fish like salmon, tuna, sardines, trout and oyster could do the heart good.Scientists set out to find the exact amount of omega-3 fatty acids needed to lower blood pressure in a new study published in the Journal of the American Heart Association.It found people had a 'modest' blood pressure reduction from consuming three grams of fatty acids daily.A note before you hit the shops - the study says that's equivalent to about a 114 to 142g serving of Atlantic salmon.Fish oil supplements may contain about 1000mg of omega-3s per pill, but doses can vary.

For adults with high blood pressure or high blood lipids, their findings showed having more than three grams of omega-3 fatty acids every day may boost the blood pressure-lowering benefit even further.

The study looked at 71 clinical trials that examined the relationship between blood pressure and these fatty acids in adults with or without high blood pressure or cholesterol disorders. "Our study supports the [US Food and Drug Administration] guidance that EPA and DHA omega-3 fatty acids may reduce the risk of coronary heart disease by lowering high blood pressure, especially among people already diagnosed with hypertension," said study author Xinzhi Li, MD, PhD.

He cautioned: "However, while our study may add a layer of credible evidence, it does not meet the threshold to make an authorized health claim for omega-3 fatty acids in compliance with FDA regulations."Researchers analysed 71 clinical trials worldwide from 1987 to 2020 with 5,000 participants combined."Most of the studies reported on fish oil supplements rather
