The state of your gut is another important consideration that can have a significant influence on your brain function. Your gut is quite literally your "second brain."

Just as you have neurons in your brain, you also have neurons in your gut, and gut bacteria transmit information from your GI tract to your brain via your vagus nerve. Abnormal gut flora has been associated with abnormal brain development, and may be an overlooked culprit in many cases of depression. In addition to avoiding sugar, one of the best ways to support gut health is to consume fermented vegetables, which are loaded with beneficial bacteria.
