Nuts are all yummy and savoury when consumed, but one should never forget the words of caution that come along when eating peanuts. Food allergies affect 5% to 10% of the population. Common triggers are peanuts, legumes (like beans and peas), and tree nuts like pecans and almonds. Even anything that has come into contact with nuts may trigger swelling, vomiting, and diarrhea if you have a strong allergy. It may even irritate your throat, making it difficult to breathe or speak.
