Almond allergy symptoms

In this article we will review almond allergy symptoms.The almond which is a dry fruit is considered as the tree nut although almond belongs to the family of the Rosaceae that also include apple, pear, peach, cherry, plum, nectarine, apricot, and the strawberry. Many of the processed foods may contain the almond for example the sweets, snacks, baked goods, ice cream, chewing gum, drinks like almond milk and curry.

Almond allergy symptoms:

In this paragraph we will discuss about the almond allergy symptoms. Lets move on with the almond allergy symptoms

Severity of almond induced allergic reactions ranges from the slight oral allergy syndrome like itching at the mouth and tongue soon after the chewing and the ingesting of the fruit to the severe and even the potentially fatal systemic reactions like the anaphylactic shock, hives and the swelling of the throat and asthma. The severity of the allergic reactions depends on what protein is in the almond due to which the patient has become allergic to.

Tree nuts are considered one of the most frequent causes of the food allergy. However, the almond allergy seems rather unusual as compare to other types of the allergies. No good data for the occurrence of the almond allergy are available too. In the United States and in the United Kingdom, frequency of the tree nut allergy as a whole is estimated to range between 0.2 percent and 0.5 percent both in the children and in the adults too. The tree nuts allergies appear early in the childhood, however in the Mediterranean countries sensitization to the heat resistant proteins might appear in the adults. It is presently not known whether the allergic patients might become tolerant after some of the years of its avoidance.

Several types of the almond allergic subjects could be distinguished.

Almond allergy symptoms

Patients with the birch pollen allergy :

In such patients the almond allergy is the consequence of the cross reactivity the similarity between the pollen allergens and the similar proteins in the vegetable foods. Because such proteins are rapidly destroyed in stomach this kind of the food allergy is generally very mild, in most of the cases, the oral allergy syndrome is only allergic symptom. In addition, such patients tolerate the heat processed almonds because the allergens are heat labile.

Patients who are primarily allergic to tree nuts:

Allergenic proteins which are responsible for this type of the allergy are heat stable and resistant to the digestion in the stomach. As a result, the patients reacting to such protein may experience the severe allergic reactions. Furthermore, It is very important to be aware of the fact that severe reactions might occur on the first exposure to the nut in the patients allergic to the different nut. The cross reactivity among the tree nuts are very variable both in the real life and even when measured in the blood samples. Therefore, it is extremely important that thethe patients with the history of the severe allergic reactions to the tree nut avoid the ingestion of some other nuts until the absence of the reaction to the almonds has been unequivocally demonstrated by the  properly performed diagnosis about it. The cross reactivity between the tree nuts and the peanut is frequently observed on the skin tests or in the blood samples due to the presence of the similar proteins, however actual clinical cross reactivity is very rare.

Patients who are allergic to thepeach and other Rosaceae :

Such type of patients react primarily to the heat stable protein present mainly in the Rosaceae but also in the most other plant derived foods. Such proteins are widely cross reacting allergen. Most of the LTP allergic subjects have the history of the peach allergy the OAS and more severe reactions, and almost  25 percent report reactions of eating the almonds. The allergy to some other tree nuts is possible in such patients. The LTP is heat stable and resistant to the digestion in  stomach, as the consequence the allergic patients might potentially experience some severe allergic reactions.

Patients allergic to the latex:                                    

Some of the cases of the almond allergy have been reported in the patients allergic to the natural rubber latex. But, such associations do not seem typical frequent.

Diagnosis of the almond allergy symptoms:

The skin tests with the fresh food are generally considered very best in vivo method to detect the walnut allergy, though the commercial extracts might prove equally sensitive in the patients sensitized to the stable allergens. In the In vitro tests like RAST, are generally also sensitive. As a consequence to the severity of the allergic reactions induced by the tree nuts oral challenge tests are very  rarely performed.


Almond might be present as a hidden allergen in the commercial food preparations. as a case of thealmond induced anaphylaxis due to the ingestion of the curry is described. Because of the possible cross reactivity, almond allergic patients should avoid the tree nuts, such as the hazelnut and the Brazil nuts, unless the good tolerance has been clearly proven by the reliable tests.

We hope that this article regarding almond allergy symptoms will help a lot in understanding the almond allergy symptoms.
