What advise should a person with low levels of the enzyme lactase receive regarding dietary adjustment?

Rationale

Avoid foods containing dairy.

Lactase is an enzyme that breaks down lactose, a sugar primarily found in milk and other dairy products. If a person has low levels of lactase, they may be lactose intolerant and can experience discomfort, bloating, and other symptoms when consuming dairy.

A (Avoid foods containing gluten) YOUR ANSWER

Gluten is a protein found in wheat, barley, and rye. It does not contain lactose and would not cause problems for someone with low levels of lactase. Avoiding gluten is necessary for individuals with celiac disease, not lactose intolerance.

B (Avoid nuts and legumes) YOUR ANSWER

Nuts and legumes are rich in protein and fiber but do not contain lactose. Therefore, they would not typically cause issues for a person with low lactase levels.

C (Avoid foods containing dairy) CORRECT

Dairy products like milk, cheese, and yogurt contain lactose. A person with low levels of lactase may have difficulty digesting these foods and can experience gastrointestinal upset as a result. Thus, avoiding dairy is a common recommendation for those with lactose intolerance.

D (Avoid red meat) YOUR ANSWER

Red meat does not contain lactose and would not be problematic for someone with a lactase deficiency. Avoiding red meat is often recommended for different health reasons, such as reducing the risk of heart disease.

Conclusion

For individuals with low levels of the enzyme lactase, the most appropriate dietary adjustment is to avoid foods containing dairy. This is because lactase is necessary for the digestion of lactose, a sugar found in dairy products. Other food groups, such as those containing gluten, nuts and legumes, or red meat, do not contain lactose and would not typically cause discomfort for those with low lactase levels.
