[/quote]Before your grandparents granparents had a genetic predispositon they had anxiety, and depression, and they may have had a hypoglycemic condition, but some people are anxious and and dont have any obvious 'crutches', and anxious, and depressed people would have hypogylcemic reactions, so what sets two anxious people apart , one with an addiction and the other with none?[/quote]
It is true that some people with an addiction have a genetic predisposition controlled by various genes that have been identified. One of them is the 'diabetic' gene.
But knowing of a gene predisposing you to an addiction, does not mean it cannot be treated.
There are many factors contributing to mental illness, but I believe insulin resistance (hypoglycemia) is very common, whether inherited or acquired. We can acquire it by eating too much sugar (source of glucose). Sometimes we eat too much sugar to beat depression or stress.
The mechanism has been explained at;

One of the results of hypoglycemia is the overproduction of adrenaline. Some people self-medicate themselves against excess adrenaline through alcohol, or benzodiazepines which are addictive. Others are struggling with anxiety attacks/depression without medication.
We all differ in the way we react to excess stress hormones, but the causes come back to a metabolic disorder that responds well to the hypoglycemic diet in most cases.
