Yes, it is true that a person can be allergic to any kind of food. Food allergies are caused by an immune system response to certain proteins found in foods. The body produces antibodies against these proteins and when the body comes into contact with them again, the antibodies cause an allergic reaction. This can range from mild to severe reactions such as hives, swelling, difficulty breathing or even anaphylaxis.
