The brain is an energy-intensive organ, using around 20 percent of the body’s calories, so it needs plenty of good fuel to maintain concentration throughout the day.
The brain also requires certain nutrients to stay healthy. Omega-3 fatty acids, for example, help build and repair brain cells, and antioxidants reduce cellular stress and inflammation, which are linked to brain aging and neurodegenerative disorders, such as Alzheimer’s disease.
In addition to making dietary changes, it is also important to take supplements to improve brain function. Out of these Omega-3-fatty acids which are mainly found in fish oil are considered essential for brain health. It was found in a clinical study that Omega-3-fatty acids increase the blood flow to the brain hence, a connection was established between omega-3 levels and better cognition, or thinking abilities.
Omega-3 fatty acids help build cell membranes in the brain and also may have anti-inflammatory and antioxidant effects that could protect brain cells.
