What Happens With a Tree Nut or Peanut Allergy? When someone has a nut allergy, the body's immune system, which normally fights infections, overreacts to proteins in the nut. If the person eats something that contains the nut, the body thinks these proteins are harmful invaders and responds by working very hard to fight off the invader. This causes an allergic reaction. Even a small amount of peanut or tree nut protein can set off a reaction. But allergic reactions from breathing in small particles of nuts or peanuts are rare. That's because the food usually needs to be eaten to cause a reaction. Most foods with peanuts in them don't allow enough of the protein to escape into the air to cause a reaction. And just the smell of foods containing peanuts won't cause one because the scent doesn't contain the protein.
