  • Omega-3 Fatty Acids can be very beneficial. A 2019 update from American Heart Association states that every 38 seconds someone dies of Cardiovascular Disease.
  • About 49% of Americans have heart disease risk factors like high blood pressure and high LDL cholesterol.
  • Recent meta-analysis revealed that those who took omega-3s fish oil supplements on a daily basis have reduced the risk of coronary heart disease death by 8%.

According to a recent survey conducted by Harvard T.H. Chan School of Public Health and Brigham and Women’s Hospital, the researchers revealed that people who consumed omega-3 fish oil supplements showed a lower risk of heart attack and other CVD (cardiovascular diseases) symptoms. The meta-analysis report stated that the experiment was conducted on more than 120,000 people. The analysis also suggested that a daily dosage of 840 mg is sufficient for the greater reduction of CVD risks.

The meta-analysis was published online in the Journal of American Heart Association on September 30, 2019.

According to author Yang Hu who is a postdoctoral fellow in Harvard Chan School’s Nutrition Department, the meta-analysis report consists of updated evidence regarding the effects of omega-3 supplements on CVD symptoms. The team found significant positive effects of omega-3 fatty acids on the risks of coronary heart disease in a dose-response manner.
Additionally, senior author JoAnn Manson who serves as chief of the Division of Preventive Medicine at Brigham and Women’s Hospital suggested that the public health organizations should recommend people to consume more fish along with a healthy diet, lifestyle, and physical exercises.
