Peanut allergy and tree nut allergy are considered different types of allergies. Peanuts are not really nuts at all, they are are actually a type of legume. Legumes grow underneath the soil, not in trees.
Peanut allergy is on the rise in the United States. Some experts say this may be due to the popularity of this high protein, high fiber food. According to the Texas Peanut Board, Americans eat about 3 pounds of peanut butter per person each year, totaling about 700 million pounds. And that’s just peanut butter!
The proteins in peanuts are very stable and stay intact through cooking and baking. This is why people with this type of allergy are often very sensitive and reactions are frequently severe. Even the smallest amount of protein, whether it’s tiny particles in the air or touching the protein, can cause a serious reaction.
Of all food allergies, peanut allergy is the least likely to be outgrown. According to research, only about 15% of children with a peanut allergy will outgrow it.
