Which of the following foods is considered an allergen derived from plants?

Soy is considered an allergen derived from plants because it is obtained from the soybean plant, which is part of the legume family. Many individuals have specific allergies to soy protein, making it a common dietary concern. Recognizing plant-derived allergens like soy is essential for those who need to avoid certain foods for health reasons, including anaphylaxis.

In contrast, fish, eggs, and milk are derived from animals. Fish is a seafood allergen, eggs are an animal product from birds, and milk is a dairy product that comes from mammals. They do not come from plants, which is why they don't fit the criteria for plant-derived allergens. Understanding the classification of food allergens helps in managing food allergies effectively and ensuring proper labeling and consumer awareness.
