What is the best food for the brain? That is indeed a controversial debate. This issue contains two diffrent side of view. One side of it is related to our nutrition, and other side of it is akin to spiritual part of our brain. At first glance, a lot of people are thinking about its material sides, and most of them thinking about what nourishments are good and healthy for our brain, but in the contrary, some people are thinking about what is beneficial for improve our brain and our mental health. Although it is a an extensive issue to discuss, but if I just mentioned some best food for our brain, I would pick healthy food, exercise, and reading book. Maybe we are aware of the effect of food and exercise on our brain, but unfortunately there are few people that worrying about spirtual side of their own brain. Overall, if we wanted a healthy brain, we would consider all sides of its nutrition, corporeally and spiritually.
