Body Chemistry and AlcoholismIn the past forty years, research has linked alcoholism to biochemistry in various ways.The Masked Allergy TheoryAllergy and addiction were thought to be different reactions but recent research suggests that the only difference is in the timing of the symptoms.Low Blood Sugar and AlcoholismIt is well known that recovering alcoholics crave sugary foods. Increasing evidence is showing that many alcoholics have shown symptoms of faulty sugar metabolism since childhood.Caffeine and AlcoholCaffeine is another substance which gives temporary relief to the symptoms of low blood sugar and it is possibly because of this that heavy drinkers often drink cola, tea and coffee during the day and alcohol in the evenings. The caffeine eases the low blood sugar symptoms (a large part of the misery of a hangover) until the evening drinking starts and so the circle continues. This would fit with the theory that alcoholics have nutritional deficiencies before becoming alcoholics and that while in part their nutritional deficiencies are due to mal-absorption caused by alcohol, some degree of deficiency precedes the drinking.Alcohol and HeredityIt could be argued that bad character traits can be inherited – so can biochemical make-up.*47\326\8*
