This area looks at the allergens which are most commonly associated with allergy, including peanut and tree nut allergy, cow’s milk allergy, sesame allergy, shellfish and fish allergy, egg allergy and allergy to insect stings.
Peanuts and Tree Nuts
The peanut is a legume and in a different botanical category to tree nuts. The term ?tree nuts? refers to a variety of nuts including almonds, walnuts, brazil nuts and cashew nuts. Despite the botanical difference, many people with peanut allergy react to tree nuts and vice versa.
Allergy to these foods can be severe. Some people experience only mild symptoms, but severity is difficult to predict and all cases should be assessed by an allergy specialist. Even mild symptoms such as a tingling of the lips should never be ignored because it is possible that future reactions may be more severe.
People at risk of severe reactions may be prescribed adrenaline auto-injectors (such as Anapen, EpiPen or Jext).
Allergy to peanuts and tree nuts can be perfectly well managed. The number of people who die of food allergy is actually very small.Peanuts and tree nuts must be declared on the label whenever they appear in pre-packaged food even when present in minute quantities.
