Possibly because you can completely avoid alcohol but you can't completely avoid food. Some large percentage of people who would have been addicted to other substances (due to less than optimal nature/nurture) but didn't, because they did not take those substances, instead became addicted to the substance of food. It might be more useful to see addicts to every type of substance as a large pool of anxious people who came across a substance to self-soothe, and figure out how to address the anxiety problem first.
