Omega-3 fatty acids
- Context (TOI): A recent study challenges the health benefits of fish oil supplements rich in Omega-3 fatty acids.
- The study concluded that regular fish oil was associated with a 13% higher risk of developing atrial fibrillation (a heart rhythm disorder) and 5% increased risk of stroke in the general population but could help in managing disease progression.
- Fish oil is derived from the tissues of fatty fish. It is rich in omega-3 fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).
- These essential fats are known for their anti-inflammatory properties and their role in maintaining various bodily functions, including brain and heart health.
Omega-3 fatty acids
- Omega-3 fatty acids are a type of polyunsaturated fatty acid (PUFA).
- It is rich in foods such as marine fish, walnuts, soybeans, and seeds such as flax seed oil and canola oil.
Types
- EPA (eicosapentaenoic acid): EPA is a “marine omega-3” because it is found in fish.
- DHA (docosahexaenoic acid): DHA is also a marine omega-3 found in fish.
- ALA (alpha-linolenic acid): ALA is the form of omega-3 found in plants.
Benefits of Omega-3 fatty acids
- It lowers blood pressure and helps reduce joint inflammation in rheumatoid disease.
- It helps prevent and alleviate dementia, depression, asthma, migraine, and diabetes.
- High doses of EPA and DHA can significantly lower blood triglyceride levels. DHA, in particular, is vital for brain health and cognitive function.
- It reduces the risk of heart attack and prevents arrhythmias.
