Is there any part of plants that can cause more allergies

Theoretically, you can be allergic to any part of the plant. However, according to the type of food and depending on what is being sensitized reaction may occur to one or other substance or molecule. Allergic reactions caused by plant foods have the distinction of being caused not only by one in particular, but also by a common component with other food. This phenomenon is known as cross-reactivity.

There are proteins that are associated with the cytoskeleton of many plants and participating in the shape and movement of the cells of the plant world. These proteins are called profilin and are considered true paral?rgenos responsible for cross-reactivity between fruits, vegetables and pollens. They are very resistant to gastric digestion and increased temperature. This explains that profilin allergic systemic reactions do not usually present, but only localized in the area of ??the oropharynx. Other proteins capable of eliciting reactions are the group of plant defense proteins located mainly on the surface of the skin, to meet what its name suggests: the defense of the plant. highlights include: Allergens belonging to Group 10, known as Bet v 1 homologues (acronyms used to describe a birch allergen). As profilins, proteins are not resistant to heat or digestive enzymes. Sensitization to these allergens occurs via respiratory initial form pollen involved, and secondarily oral symptoms with vegetable appear. The group 14, or lipid transfer proteins (LTP calls). They are characterized by their high resistance to digestive and increased temperature enzymes. These properties give them the ability to sensitize directly via the digestive tract and explain the symptoms may affect multiple systems. One of the first fruit which was described peach. Groups 3 and 4 or chitinases are allergens associated with latex-fruit syndrome. some fruits are characterized by the association of allergy in patients allergic to latex. Among fruits involved include banana, avocado, chestnut and kiwi. How is suspected allergy to fruits and vegetables? Allergy can come in many forms and can sometimes be difficult to relate the appearance of a certain discomfort with a particular food and also from a source 100% natural, as in the case of fruit or vegetables, especially the false myth to think that the more processed foods, stews type, sauces and seafood, among others, cause more allergies. Banana can cause allergic reactions of varying intensity, from pruritus (itching) oral or general, sneezing, watery eyes or skin redness, to gastrointestinal symptoms (abdominal pain, vomiting, diarrhea), urticaria-angioedema, shortness of breath, dizziness and hypotension. Sometimes, symptoms may appear only handling fresh food, and mainly manifested as contact urticaria, contact dermatitis, conjunctivitis or respiratory symptoms such as rhinitis or asthma. Suspect and study a possible allergy to a fruit or vegetable in the following situations: - If symptoms appear shortly after taking a concrete plant. - If symptoms occur repeatedly after taking the same plant. - If no other cause is found to explain the symptoms. Before the onset of discomfort after a meal, it is very important to remember everything ingested to the smallest detail and annotate: the time elapsed since ingestion, a ratio of the order of appearance of symptoms, if they disappeared in minutes or hours and whether he specified care in the emergency department. What are the most common symptoms? The most characteristic clinical form of presentation corresponds to consistent local manifestations in oral, oropharyngeal or otic itching, which is known by the name of oral allergy syndrome (ODS). Fruits associated with this syndrome mainly belong to the family Rosaceae (apple, peach, pear, strawberry, cherry, apricot and plum among others). Sometimes sores can also appear erythema, around the mouth, and swelling of lips and tongue, which is known as oral angioedema. These symptoms occur immediately, within 15 minutes of ingestion of food, usually mild and disappear within a few minutes of your home. Skin redness, type welts, in an itchy or dermatitis by contact with the plant may arise, such as some vegetables, such as eggplant or zucchini, whose content of histamine can cause further contact dermatitis in which the handle. Sometimes these symptoms are followed by systemic manifestations with involvement of the digestive or respiratory system. Reactions associated cutaneous and systemic disease are known by the name of anaphylaxis, and are the most serious allergic reactions. As for the respiratory symptoms are rare cases of acute bronchial asthma or allergic rhinitis after ingestion of such foods; More often, these symptoms occur by inhalation of particles in the air and come from foods such as, for example, particles of fish or cereal flour (baker asthma). Regarding the digestive symptoms, the most common symptoms are nausea, vomiting, abdominal pain and / or diarrhea. These symptoms may appear quickly and abruptly shortly after taking the plant, but also smoother and more prolonged, hours after ingestion. Read more allergy symptoms
