Fish oil containing omega-3 unsaturated fatty acids, does not contribute to a significant reduction in the risk of premature death from cardiovascular disease. To such conclusion scientists of the University of East Anglia, who conducted a systematic review of the scientific literature. About it reported in a press release on the website of the institution.
Experts analyzed 79 studies that, in total, involved 112 thousand people. The volunteers were divided into groups in accordance with the level of use of fish oil in the course of the year, after which it was evaluated the condition of their heart and blood vessels.
It turned out that large quantities of fish oil only slightly reduced the risk of death from cardiovascular diseases. Also there was no significant difference between the indexes of frequency of heart attacks or strokes in people who took dietary supplements, or comply with a regular healthy diet. According to scientists, greater health benefits can be obtained if eating seafood, which in addition to unsaturated fatty acids contain selenium, iron and vitamin D.
The researchers report that they found little positive effect from alpha-linolenic acid, which is also contained in the rapeseed and walnuts. It can prevent death from ischemic heart disease only one in a thousand people.
