Omega-3 Fatty Acids: The Key to Brain Health
Omega-3 fatty acids are essential polyunsaturated fatty acids for the body, with the three most important being EPA (eicosapentaenoic acid), DHA (docosahexaenoic acid), and ALA (alpha-linolenic acid). These fatty acids have broad and profound effects on human health.

Brain health is one of the most important functions of Omega-3. DHA is a major structural component of the brain and retina, accounting for about 40% of brain fat. Adequate DHA intake helps maintain cognitive function, improve memory, and may reduce the risk of cognitive decline and dementia.

Cardiovascular protection is another important benefit of Omega-3. EPA and DHA can lower triglyceride levels in the blood, reduce the risk of blood clot formation, and improve vascular endothelial function, thereby reducing the incidence of heart disease and stroke.

Anti-inflammatory effects make Omega-3 excellent in treating chronic inflammatory diseases. They can produce anti-inflammatory metabolites, helping to relieve inflammatory diseases such as arthritis and asthma.

The imbalance of Omega-6 to Omega-3 ratio in modern diets is a common problem. The ideal ratio should be 4:1 to 1:1, but in modern diets this ratio is often as high as 20:1, leading to a pro-inflammatory state.
