Did you know that when you stick your tongue out, it should look pink, not white? Also, there should be no deep grooves or scalloped edges. Also, if a tongue looks like a map of the world, that is a sign that the body is full of inflammation. Oftentimes, what is going on in the tongue is also going on throughout the digestive tract. Since the gut and the brain are so closely linked communication-wise and health-wise, oftentimes the brain is inflamed when the gut is inflamed. All these things are related. Some of my patients actually tell me that they can feel their brain hurt after eating certain foods. Several of my patients begin care who start with white tongues. All of them improve! When you heal your brain, your gut improves. When you heal your gut, your brain function improves.
