You may have heard that eating fish makes people smart--and there is truth to that. Omega-3 consists of two fatty acids, one of which is docosahexaenoic acid (DHA), which is essential for the optimal functioning of many parts and processes of the body, including brain activity.
Omega-3 DHA is necessary for ideal neuronal functioning, as it interacts with cell membranes to optimize learning. It is also a key ingredient in infant brain development.
The densest concentration of Omega 3-DHA is found at the back of the retina, where it helps the pigment rhodobsin respond to visual stimulation so you see things quickly.
An increase in Omega-3 DHA, along with the other Omega-3 fatty acid, EPA, lowers heart rate and reduces the risk of fatal cardiovascular problems such as heart disease and heart attacks.
Incorporating Omega-3 into your diet lowers cholesterol and increases the good type of cholesterol, HDL.
Although medical professionals still debate about whether DHA effectively treats or prevents Alzheimer's, in a memory improvement study at the Martek Biosciences Corporation, Karin Yurko-Mauro, PhD, found that taking DHA supplements improved the memory of individuals suffering from mild memory problems.
