News: Once in decline, deaths from cardiovascular disease (strokes, heart attacks, etc.) in the United States “have been rising dramatically since 2011.” The American Heart Association projects that 45% of the population in the U.S. will have some form of cardiovascular disease (CVD) by 2035 (high blood pressure, in particular). And, the cost of this disease may be over $1 trillion dollars by 2035–a huge economic burden.
To combat CVD, the NIH estimates that nearly 19 million people in the U.S. take fish oil/omega-3 supplements. The notion that “dietary fish oil supplements promote heart health” has been accepted as fact for years.
However, there has never been any research to back that up. A 2019 comprehensive review that looked at some 300 trials and interventions involving over 992,000 participants concluded that fish oil/omega-3 supplements had, at best, “low-certainty evidence” for promoting reduced risk of myocardial infarction and coronary heart disease.
What does this mean?
“All studies of fish oil supplements conducted to date have failed to show any significant clinical benefits.” “Consumers are wasting their money on supplements in an effort to reduce cardiovascular risk.”
Be skeptical; make your decisions based on real evidence, not hearsay.
