A lot of our brain and a lot of the integrity of the nerve cells, the so-called neurons in our brain and the other types of cells comes from fat. And that's because nerve cells and other cells in the brain have a external layer. It's what's sometimes called a double- layered membrane. It's essentially two thin layers that serve as a boundary between those cells. And that boundary is very important because how things pass across that boundary actually regulates the electrical activity of neurons, which is the way that neurons fire and communicate and keep you thinking and acting and doing all the good things that those neurons allow us to do. And those membranes are made up of fats, but they're not made up of the fats that are around our belly, around the other organs of our body. They're not made up of storage fat. They are made up of structural fat.
