We don’t use our taste glands properly. We eat very fast even without having taste. Our gland are very closely connected to mind, and if mind is not connected with taste glands then you can never satisfied internally. And when mind is in dissatisfaction then brain cells are uncharged. In this situation mind and brain cell become frustrated and demands more and more spicy food and alcohol. So the result is major diseases.
I have experienced that if mind is not connected with taste glands then brain cells can never absorb vitamin and mineral etc properly instead of having all type of vitamin and minerals. My meditation experience says ,This dissatisfied mind and uncharged brain cell occurs diabetes problem also.
