Question 4

Avoid foods containing dairy

Individuals with low levels of the enzyme lactase should avoid foods containing dairy, as these products can lead to digestive discomfort and symptoms associated with lactose intolerance.

A) Avoid foods containing dairy

This option is correct because individuals with low lactase levels cannot properly digest lactose, the sugar found in dairy products. Consuming dairy can result in symptoms such as bloating, gas, and diarrhea, making it crucial for these individuals to eliminate dairy from their diet.

B) Avoid nuts and legumes

This option is incorrect. Nuts and legumes do not contain lactose and are generally safe for individuals with lactose intolerance. In fact, they can be good sources of protein and nutrients that may be beneficial for those avoiding dairy.

C) Avoid red meat

This option is incorrect. Red meat does not contain lactose and does not contribute to the issues faced by individuals with low levels of lactase. Therefore, there is no need for someone with lactose intolerance to avoid red meat.

D) Avoid foods containing gluten

This option is incorrect. Gluten is a protein found in wheat and certain grains, not in dairy. Avoiding gluten is not necessary for individuals with lactose intolerance, as it does not affect their ability to digest lactose.

Conclusion

Avoiding foods containing dairy is essential for individuals with low levels of lactase, as it directly addresses their inability to digest lactose. Other options, such as avoiding nuts, legumes, red meat, or gluten, do not relate to lactose intolerance and thus do not provide appropriate dietary advice for managing this condition.
