New study shows that omega-3s promote heart health and reduce the risk of heart attacks.
Cardiovascular disease is the leading cause of death worldwide and the cause of death in approximately 17.9 million people each year. Bad health conditions like high blood pressure, high cholesterol, obesity, and smoking lead to cardiovascular disease.
There are many prevention strategies available to improve heart health and prevent cardiovascular disease. One of the most popular is eating foods high in omega-3s like fish. Currently, the National Institutes of Health has set the appropriate intake for omega-3 fatty acids at just over one gram for adults.
Research sponsored by the Global Organization for EPA and DHA Omega-3 Fatty Acids (GOED) was recently completed and 40 clinical studies reviewed on the benefits of omega-3 fatty acids. The meta-analysis that summarized the results of these studies was published in the journal Mayo Clinic Proceedings.
Three main omega-3 fatty acids were examined: alpha-linolenic acid (ALA), eicosatetraenoic acid (EPA), and docosahexaenoic acid (DHA). This analysis focused on EPA and DHA and examined data from all randomized clinical trials published prior to 2019 that looked at their use to improve heart health.
The review only included studies using EPA and DHA as dietary supplements. All included studies were rated according to the strength of evidence. Their results were statistically analyzed and the relative risk of cardiovascular disease, myocardial infarction and fatal myocardial infarction determined for the dosage of EPA and DHA used in the study.
All of the studies examined showed that the omega-3 benefits presented a lower risk of fatal heart attack, heart attack, coronary artery disease, and death from coronary artery disease. The review also provided evidence that the higher the omega-3 dose, the lower the risk of coronary heart disease.
Based on the review’s data, the study’s authors recommend supplementing diets with EPA and DHA by eating foods like salmon, anchovies, and sardines. Dr. However, Carl Lavie, one of the study’s authors, said in a press release, “People should consider the benefits of omega-3 supplements in doses of 1000 to 2000 mg per day – far higher than usual, even for people who are regular To eat fish. “
