Given this information, what can you conclude about milk?
A. Lactose is a carbohydrate, not a protein and is therefore not the cause of true milk allergies. B. The protein that causes a true milk allergy is lactose. C. All people who are lactose intolerant are also allergic to milk. D. Yogurt contains live and active cultures of Lactobacillus acidophilus bacteria and therefore prevents an allergic response in people with a true milk allergy.
