Like everyone, you may have wondered, "Why do my parents urge me to eat fruits and veggies and to stop eating junk foods?" The answer is, "You are what you eat!" What we eat can determine the composition and the activities of our cells. A healthy diet with the proper amounts of nutrients should be eaten regularly, to keep our cells and organs– including the brain–healthy.

Throughout life, the brain monitors our daily operations and activities and communicates with other organs, coordinating their functions. Brain cells are called neurons. A neuron can receive and transmit signals to different parts of the body. A neuron connects with other neurons to transfer their signals. The neuron usually transfers the signals in the form of chemical molecules and electric impulses.

When you want to move your hand, the brain sends a message to muscles in the hand, telling them to contract. Neurons also communicate with other cells in the brain, called glial cells. Unlike neurons they do not produce electric impulses. Their functions is to maintain balance in the nervous system by providing support and protection for neurons. There are two types of glial cells: microglia and astrocytes. Microglia are the main immune cells of the brain, helping to protect the brain from infections. Astrocytes provide neurons with the nutrients they need to stay healthy.

Messages sent by the brain not only allow us to perform physical tasks like moving around, but also help us to perform cognitive tasks. Cognitive tasks include actions like thinking, learning, remembering, memorizing, planning, imagining, organizing, and concentrating. Therefore, a problem that affects the brain can change our thinking, emotions, or behaviors.

There is a direct relationship between the foods we eat and the functioning of our brains. Proper, healthy nutrition can benefit the brain in several positive ways. A healthy diet can increase the production of new neurons, a process called neurogenesis. The more the connections between neurons the better they can communicate, and the better we can learn, think, and memorize.
