People Who Are Lactose Intolerant Can Often Consume Some Products

Multiple Choice

People who are lactose intolerant can often consume some products made from milk such as cheese and yogurt. By comparison, people with a true milk allergy, which involves an immune response to milk protein, cannot consume milk or products made from milk. Given this information, what can you conclude about milk?

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