It makes intuitive sense that dietary cravings can indicate something about brain chemistry. For instance, a new study suggests that “alcoholics with strong cravings for carbohydrates may form a distinct
subgroup of patients with this disease. This type of alcoholic may drink to increase their serotonin levels, and may
increase their intake of carbohydrates if not drinking, to achieve the same effect, the researchers suggest.” Recognition of this alcoholic subgroup, if valid, might impact their drinking with therapeutic strategies that affect serotonin.
