The perceived inability to eat certain foods goes directly to milk drinking. Some people avoid all dairy products because of LI. But realistically, people don't stop eating their favorite foods like cheese, especially on pizza, and ice cream even if they are LI. That's probably why lactose-free ice cream never breaks through in the market.
One thing that's not known and would be helpful is whether adult perceptions of foods that "can't" be eaten because of LI affects the views of their children. Some children, especially Hispanic girls, were more likely than others to think of themselves as LI and so avoid dairy. If milk can be added to breakfasts, however, it's more likely to be drunk.
