The brain: 75% water and 60% fat

Let's face it: There are good fats and then there are bad fats. So, our brains need, not only water, but also the healthy fats that we get from oil, avocados, nuts, and fish. In fact, healthy fats can promote blood flow to the brain and also aid in functioning. Saturated fat, DHA (omega-3 fatty acid), and polyunsaturated fat have all shown to improve not only brain function, but certain conditions like depression, bipolar disorder, ADHD, and even dementia.
