The researchers concluded that at least nine out of ten children with similar allergies would not have a serious reaction to touch or smell, but the study only looked at peanut butter, not other forms of peanut. A third had a mild reaction to touch including redness, itching or rash in a small area, but these were not serious, and no medication was needed. One small study showed that when 30 children with serious peanut allergy had contact with peanut butter through touch or smell, none of them experienced anaphylaxis and none reacted to smell. People with peanut and allergy often worry that touching or smelling nuts could cause a serious reaction, but research suggests this is not common. About 1 in 50 children and 1 in 200 adults in the UK have a nut allergy. Peanut and tree nut allergies are common – they are the most commonly known foods to cause anaphylaxis. For example, it’s quite common for people with cashew nut allergy to be allergic to pistachios, and for people with walnut allergy to be allergic to pecans. Many people who are allergic to tree nuts are only allergic to one type of tree nut, but some are allergic to more. As the plant families are different, many people only react to peanuts but not to any tree nuts, and vice versa. Tree nuts are in different plant families and include almonds, hazelnuts, walnuts, cashew nuts, pecans, Brazil nuts, pistachios and macadamia nuts. The peanut is a legume and is in the same plant family as peas, beans and lentils. It is the release of these chemicals that causes the allergic symptoms When this happens, the body releases chemicals, such as histamine, in response to exposure to the food. Food allergy occurs when the body’s immune system wrongly identifies a food as a threat. Peanut and tree nut allergies are types of food allergy.
