3. You are counseling Lillian, who is lactose intolerant, about foods to avoid.
You know she misunderstands the teaching when she tells you she can have:
1. Yogurt.
2.Foods containing whey.

products or by eating lactose-rich foods in small amounts or in combination with
low-lactose or lactose-free foods.
