Which of the following is NOT an example of a food that can irritate acne?

The correct answer, apples, is notable because they are generally recognized as a healthy food that is unlikely to cause irritation or acne. Apples are high in fiber, vitamins, and antioxidants, which may actually contribute to overall skin health. Unlike certain foods that have been linked to exacerbating acne, such as dairy products, chocolate, and potato chips, apples do not contain preservatives, high levels of sugar, or other compounds often associated with skin irritation.

In contrast, foods like chocolate and dairy products have been studied for their potential to influence hormone levels or produce inflammatory responses, which can in turn exacerbate acne conditions. Potato chips, being high in refined carbohydrates and unhealthy fats, may also contribute to acne by promoting inflammation and affecting insulin levels. Therefore, apples stand out as a beneficial choice for those looking to maintain healthy skin.
