<human>: Is it true that a person can be allergic to any kind of food?
<bot>: Yes, it is true that a person can be allergic to any kind of food. Allergies are an immune system response to something the body considers harmful. Food allergies occur when the body’s immune system mistakenly identifies a particular food as harmful and produces antibodies against it. These antibodies cause symptoms such as swelling, hives, difficulty breathing, vomiting, or even anaphylaxis (severe allergic reaction).
