Which of the following represents a condition related to food consumption?

The choice of lactose intolerance as the correct answer highlights a specific medical condition that directly affects an individual's ability to consume certain foods. Lactose intolerance occurs when the body lacks sufficient amounts of lactase, the enzyme needed to digest lactose, which is present in dairy products. This leads to symptoms such as bloating, gas, and diarrhea when lactose-containing foods are consumed.

In contrast, gluten intolerance refers to a sensitivity to gluten found in wheat, barley, and rye, making it also a condition related to food; however, lactose intolerance is more widely recognized in a nutritional context. A healthy diet, while crucial for well-being, is a general concept rather than a specific condition, and calorie-rich foods are merely a description of food composition rather than a health condition or dietary issue. The focus on lactose intolerance makes it clear that the question pertains to a defined food consumption problem faced by many individuals, illustrating the importance of understanding dietary restrictions to ensure proper nutrition.
