In recent years, many people turned to consume dietary supplement for various reasons. Among the most used supplements, there are omega-3 supplements that are told to help the heart and circulatory system. However, a recent study might have another conclusion. Namely, the omega-3 supplement might not benefit the cardiovascular system.
Omega-3 is a type of fat that’s commonly found in seafood, fatty fish, some sorts of nuts, and oils. There are three types of omega-3 fatty acids:
- alphalinolenic acid (ALA)
- eicosapentaenoic acid (EPA)
- docosahexaenoic acid (DHA)
DHA and EPA are commonly found in seafood and fatty fish, such as salmon, tuna, sardines, and so on. On the other hand, ALA is an essential fatty acid, meaning that cannot be produced by the body alone. Thus, ALA must be taken from foods, exclusively.
Omega-3 supplements might not benefit the cardiovascular system
Various studies concluded that people who consume fatty fish present lower risks of developing cardiovascular diseases. However, the National Institutes of Health (NIH) stated that the research in this regard is shallow. “Fish oil was the most popular natural product used by adults in the United States in 2012,” concluded an NIH survey. By 2012, about 19 million US residents consumed fatty fish oil.
A new study, however, carried out by the Cochrane University’s researchers reviewed more than 80 previous studies totaling about 112,000 participants. The review had the purpose of comparing the benefits of taking omega-3 supplements and the advantages of an omega-3-rich diet
The survey showed that omega-3 supplements had “little or no effect” on reducing the risks of developing cardiovascular diseases and heart attack.
On the other hand, taking omega-3 from diet appeared more beneficial for cardiovascular health than omega-3 supplements. In conclusion, “the most trustworthy studies consistently showed little or no effect of long-chain omega-3 fats on cardiovascular health. On the other hand, while oily fish is healthy food, it is unclear from the small number of trials whether eating more oily fish is protective of our hearts,” concluded Lee Hooper, the review’s leading author.
