Which group of foods could be classified as potential allergens?

The classification of potential allergens is typically associated with certain food groups that are known to provoke allergic reactions in susceptible individuals. Dairy products and nuts are among the most common allergens that can cause severe reactions such as anaphylaxis.

Dairy includes milk and products derived from it, which contain proteins that some individuals are sensitive to, like casein and whey. Nuts are also notorious for causing allergic responses; tree nuts and peanuts are particularly well-documented as allergens that can lead to serious health issues.

Fruits and vegetables, grains and legumes, and meats and fish can cause allergies, but they are less commonly associated with severe allergic reactions compared to dairy and nuts. Thus, while other groups can be allergens, the specific pairing of dairy and nuts highlights two of the most prevalent and impactful allergens in the diet, making this answer the most fitting.
