In Mediterranean countries, people with apple allergy do not have birch-pollen allergy. Instead they often have allergy to peach Regarding the birch-fruit-vegetable-syndrome, about 70% of birch pollen-allergic patients develop symptoms of allergy to plant foods, most frequently involved being Rosaceae fruits (mainly apple), nuts (especially hazelnut), and vegetables from the Apiaceae family (mainly celery and carrot).

Although symptoms are generally mild and take the form of oropharyngeal contact urticaria, they can extend to allergic shock, particularly in the case of ingestion of protein-rich soy products [12,13,14] A strong association was also found with allergies to various foods, such as apple and hazelnut, and a moderate association with allergies to potato and carrot. Sensitization without clinical relevance was seen with avocado, rye and wheat flour, pineapple and papaya, and their enzymes bromelain and papain Oral allergy symptoms were reported most frequently (81.6%), followed by skin symptoms (38.2%) and rhinoconjunctivitis (29.5%).

The frequency and the type of allergic reaction seem to vary considerably from one geographic region to another depending on the presence of birch, alder or hazel trees. studied 600 patients with Rosaceae (apple, pear, peach.

Pollen Food Allergy Syndrome (PFAS), also known as oral allergy syndrome, is caused by cross-reacting allergens found in both pollen and raw fruits, vegetables, or some tree nuts. The immune system recognizes the pollen and similar proteins in the food and directs an allergic response to it. People affected by PFAS can usually eat the same. 1. Cross-reactivity is the reason for OAS symptoms. OAS is the result of a confused immune system. The pollen of some trees and grasses are similar to the proteins of certain raw fruits, vegetables, seed or nuts. 2. Birch, alder, ragweed, mugwort, Timothy grass and orchard grass pollen cause most OAS symptoms Oral Allergy Syndrome can occur in people with seasonal pollen allergies (hay fever) and is due to cross-reactivity between certain foods and pollens.

Management and prognosis Additionally, in our study, hazelnut Cor a 1.04 and apple Mal d 1 were recognized more frequently and with a higher median titer than alder's Aln g 1 and hazel's Cor a 1.01. Therefore, the sensitization potential of PR-10 proteins from pollen other than Bet v 1 appears limited Molecular allergy diagnostics using apple as an example: Mal d 1 is the related allergen to birch pollen Bet v 1. Mal d 1 is susceptible to heat and digestion. Those who only have IgE to Mal d 1 can tolerate cooked or baked apples and only have an oral allergy syndrome when eating raw apples

Cross reactions with OAS induced by apple or hazelnut. Patients showed an increased rate of skin reactivity to fresh apple, but 87 % of them (vs only 8 % of controls) could tolerate a significantly higher amount of offending food.

Hazelnut allergy is often seen in patients with allergic rhino conjunctivitis and tree pollen allergy. This is mainly caused by ingestion of hazelnuts or its products. This is also called oral 'allergy syndrome' which is caused by the cross-reactivity between tree pollen allergens, especially alder, birch, hazel pollen and hazelnut proteins. Oral allergy syndrome, also called pollen food allergy syndrome or PFAS, is a type of food allergy caused by certain allergens found in both pollen and raw vegetables and fruits and some nuts. People affected with this syndrome can tolerate the cooked form of the same fruit or vegetables. However, they develop an allergic reaction upon consuming them raw This list indicates botanical relationships of several foods.
