It's no secret that what you eat affects your body. But as a new video produced by TED-Ed points out, diet affects brain functioning more drastically than you might have thought. The short film highlights the variety of ways that food changes day-to-day cognitive functions.
The majority of the brain's weight—with the exception of the liquid contained inside—comes from fats. Glucose, proteins, micronutrients, and amino acids also make up brain matter, and in one way or another, all of these components originate in our food. In order to maintain a healthy balance of this brain material, the body requires an intake of essential fatty acids, and the nutrients we put in our bodies can ultimately have a strong effect on mood, alertness, sleep patterns and more.

As the video points out, actions and moods can be altered based on the brain's access to omega 3 and 6 fatty acids. Consuming nuts, seeds, fatty fish, and other foods high in these nutrients are "crucial to the creation and maintenance of cell membranes" in the brain. On the flip side, consuming other forms of fat—like trans and saturated—could have a negative effect on cognitive health.
