[Lifestyle] Those fish oil supplements are actually dangerous for your heart

[-_-Moltres-_-]

 

We all know the heart-healthy staples: vegetables, low-fat dairy, and lean protein like fish. Fatty fish like salmon boast an extra benefit – omega-3 fatty acids, thought to improve good cholesterol and lower triglycerides. But recent research suggests a more nuanced picture for fish oil supplements and heart disease prevention. A new study in BMJ throws a curveball. While fish oil has been linked to positive outcomes for those already with heart disease, the study found that people with no existing heart problems who took regular fish oil supplements actually saw an increased risk of atrial fibrillation (irregular heartbeat) by 13% and stroke by 5%. This doesn’t necessarily mean fish itself is bad. However, for those without a history of heart disease, fish oil supplements might not offer the same preventive benefits we previously thought.The news is brighter for those already battling heart disease. Previous studies, corroborated by this latest research, show that regular fish oil supplementation can actually reduce the risk of progressing to more serious heart issues by 15%. This could mean a lower chance of a heart attack, worsening heart failure, or even death. However, Dr Rahul Agarwal, Consultant Internal Medicine, CARE Hospitals, Hitech City, Hyderabad, noted that fish oil supplements are not recommended to stop or mitigate risks related to heart diseases. Festive offer What are the problems fish oil supplements can cause? Overconsumption of fish oil can lead to problems such as elevated blood sugar levels, decrease in blood pressure, bleeding of gums and acid reflux, said Dr Agarwal. Other problems include nausea, heartburn, and toxic reactions due to elevated Vitamin A in fish oil supplements.
