To cure a headache eat something as long as it is not sugar
Low blood sugar is one of the causes of irritability and headache. Sugar is not a cure for low blood sugar, though it may raise the blood sugar temporarily and make one feel better for a while. Low blood sugar is the result of an abused pancreas which over stimulates the production of insulin in the body. It can be controlled by eating smaller meals at short intervals rather than the standard three large meals daily. The intake of carbohydrates should be cut down to the minimum. Coffee should be eliminated as it over stimulates the pancreas.
