Various studies reveal the health benefits of omega 3 fatty acids as nutritional supplement against life threatening disease like cardiovascular disease, skin disease and many inflammatory diseases. They have been linked to healthy aging throughout life. Fish-derived omega-3 fatty acids EPA and DHA have been associated with fetal development, very mild Alzheimer’s disease. Studies have shown that EPA and DHA are important for proper retinal, neuronal development and immune function. Patients with Alzheimer’s disease have been shown to be deficient in DHA, and supplementing them with EPA +DHA not only reverses this deficiency, but may also improve cognitive functioning in those patients. However, because our bodies do not efficiently produce some omega-3 fatty acids, it is necessary to obtain adequate amounts. EPA and DHA may be a safe and inexpensive link to a healthier life.
