We have all heard the term “brain food” used to identify foods that can increase the health and functioning of your brain. Fish is the most well-known brain food due to the Omega-3 fatty acids, which promote brain cell health. Fish also contains Omega-3 DHA which keeps brain cell membranes healthy and aids communication within brain cells.
Other lesser known brain foods include brightly colored produce high in antioxidants, including strawberries, raspberries, blackberries, prunes, and my favorite blueberries. Whole grains and whole grain products such as bread, rice, and pasta contain B vitamins and magnesium which assist normal brain and nerve functioning.
Feeding your brain can increase your mental energy. Mental capacity is what we use to organize our lives. When your mental energy is low, you’re likely to become more forgetful, distracted, and have difficulty thinking and completing tasks. Maximum mental energy is derived from oscillation; changing channels mentally permits different parts of the brain to be activated while others rest and can facilitate creativity. 
This sounds like great news for multi-taskers, but I am still skeptical about how productive multi-tasking really is. It is important that we stimulate different areas of our brains, learn new things, challenge ourselves, and expand our horizons.
How we function in each area of our lives can have a big impact on how we function in the others. To live to your full potential, you want to develop the greatest energy capacity possible in each key life area. When you are thinking more clearly, you can feel more confident and find life more enjoyable. When you have more mental energy, you are less likely to become exhausted by that long meeting which then tempts you to grab something from the snack machine. When you are thinking more clearly, you will find that you have more time for the things that give your life meaning.
