What advice 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 found in milk and dairy products. Individuals with low levels of lactase struggle to digest lactose, which can lead to symptoms such as bloating, diarrhea, and abdominal cramps. Therefore, avoiding foods containing dairy is the most effective dietary adjustment for individuals with lactase deficiency.

A (Avoid foods containing dairy) CORRECT

This is the correct answer as dairy products are the primary source of lactose, the sugar that individuals with low lactase levels struggle to digest. By avoiding dairy, these individuals can prevent the discomfort and digestive issues associated with lactose intolerance.

B (Avoid nuts and legumes) YOUR ANSWER

Nuts and legumes do not contain lactose, the sugar that requires lactase for digestion. Therefore, avoiding these foods would not benefit someone with low levels of the enzyme lactase.

C (Avoid red meat) YOUR ANSWER

Red meat does not contain lactose, so avoiding it would not help someone with lactase deficiency. Red meat can be a part of a lactose-free diet, provided it is not prepared with dairy products.

D (Avoid foods containing gluten) YOUR ANSWER

Gluten is a protein found in grains like wheat, barley, and rye. It is not related to lactose or the lactase enzyme, so avoiding gluten will not ease the symptoms of lactase deficiency.

Conclusion

Lactase is required for the digestion of lactose, a sugar found primarily in dairy products. People with low lactase levels, or lactase deficiency, can experience digestive discomfort after consuming lactose. Therefore, the best dietary adjustment they can make is to avoid foods containing dairy. Avoiding nuts and legumes, red meat, or gluten will not address the issue as these foods do not contain lactose.
