Miniature Salmon Prep Board Yes! Your brain is very greasy, but in a good way. More than 60% of it is fat. Unlike the lazy fat stored on the hips or belly, fat in the brain is a worker bee. It makes up the cell membranes that surround each cell and the insulation sheath around neurons that allows thoughts to travel fast from one cell to another. The more fluid and flexible those membranes, the faster you react, the more you remember, and the more creative and clever you are. The most fluid fats are the omega-3s, and the brain must love the omega-3 DHA, because 97% of the omega-3s in your brain are DHA. An accumulating body of research is showing that children, adolescents, and young adults think better, perform better on tests, and react faster when their diets are optimal in DHA. A recent study found that children performed up to 50% better on reading tests when they supplemented with the omega-3s, and studies (including the MIDAS study) find that seniors remember more and might even be at lower risk for dementia and Alzheimer’s when daily intake averages between 220 and 900 milligrams. Note: your body can’t make this fat. It has to come from the diet. That means at least 2 to 3 servings a week of fatty fish, such as salmon, mackerel, or herring. Or, take a fish oil or DHA supplement that lists specifically how much DHA is in each capsule. Photo credit: Stéphanie Kilgast via Compfight
