Which of the following is a common allergen?

Peanuts are widely recognized as a common allergen due to their potential to trigger severe allergic reactions in sensitive individuals. Allergies to peanuts can cause various symptoms, ranging from mild reactions like hives and gastrointestinal discomfort to severe anaphylaxis, which can be life-threatening. This prevalence and the severity of the reactions are what categorize peanuts as one of the major food allergens, leading to their inclusion in food labeling laws in many countries.

In contrast, while rice, potatoes, and apples can cause allergic reactions in some people, they are not classified among the top allergens. Rice is generally well-tolerated, potatoes are less likely to lead to significant allergies, and apple allergies are relatively rare compared to the widespread issues associated with peanuts. Understanding these distinctions is critical for food safety and management, particularly in settings where food is served to the public.
