Since the body burns sugar (glucose) for energy, it's imperative that a consistent level is maintained in order to retain a feeling of well-being - an ideal level is 90-100mg of glucose per 100cc of blood.
At this level we are energetic and feel good, but when the level drops to 70mg, fatigue, hunger and irritability set in. At levels below this, dizziness, exhaustion, heart palpitations and nausea are common.
The pancreas is the major sugar regulator and the body has a complicated hormonal balancing mechanism which keeps blood sugar at a fairly constant level. When the level is too high, the pancreas secretes insulin which converts glucose to glycogen. When the level is too low, the pancreas secretes glucagon and the adrenal glands secrete adrenalin, two hormones that convert glcogen back to glucose.
However, if this balancing mechanism gets out of order, it can produce either low blood sugar (hypoglycaemia) or high blood sugar (diabetes). Factors that can affect the blood sugar balance include an excessive use of white sugar, prolonged stress and nutrient deficiences.
Elimination of white sugar from the diet, together with supplements of the B-complex vitamins, chromium picolinate or GTF chromium, zinc and brewer's yeast will help to restore and stabilise blood sugar to an acceptable level.
