FACTO: Pode ocorrer reação alérgica a um alimento sem ingestão

FACT: An allergic reaction can occur to a food without ingestion.

When we talk about food allergy, the first thing we think of is that there is a reaction if the person ingests the food and that by removing it from their food they will be safe. However, depending on one's sensitivity, food allergies can manifest not only through ingestion, but also through inhalation or skin contact with food allergens (1,2).

It is important to understand how to avoid the allergen to prevent allergic reactions from occurring (3).

Allergic reaction to food by ingestion (oral)
Eating an allergenic food or food that has been cross-contaminated with the allergen is the main cause of serious reactions (3,4). Other forms of ingestion can occur through saliva, for example, through a kiss when the other person has ingested the allergen, or in medications that contain the allergen (2,3).

Allergic reaction to food by skin contact (touch)
The contact of a food allergen with the skin can cause symptoms from localized to the skin to more severe and generalized symptoms (3,6).
Contact reactions can occur not only through direct skin touching the food, but also through a kiss or touch from another person who has come into contact with the allergenic food, or through other products (e.g. cosmetics, hygiene products, plasticine). , balloons) that contain the allergen in their composition (2).

Allergic reaction to food by inhalation (breathing)
In some cases, allergic reactions can occur when food proteins are inhaled through the air (3,4). Clinical manifestations can range from a respiratory or skin reaction to a systemic reaction that can be fatal (5). They occur, for example, when during the cooking of an allergenic food the steam released contains proteins from that food (2,3,4); when powdered food (flour, powdered milk) is handled, or when food is crushed, crushed or ground, particles of that food are also released into the air (3).

Important precautions to avoid allergic reactions:
When you are around someone who has a food allergy, avoid eating anything that contains the allergen in question. If you do, wash your hands and mouth afterwards to avoid touching reactions.
Do not share cutlery, plates, cups or napkins that may have touched the allergen (3).
If an allergen comes into contact with your skin, wash it off to avoid accidentally touching your mouth, eyes, or nose (where it can cause a more serious reaction). For this reason, it's important to wash your hands before eating or touching your eyes, nose, or mouth, especially in young children (3).
In the case of very sensitive people, the inhalation of steam should be avoided in areas where foods containing the allergen in question are handled or prepared (1).

At Fidu we develop alternative recipes to create products that are more similar to traditional ones, so that all family and friends, with or without allergies, can share and consume without distinction or worries. Fidu products do not contain the 14 main allergens or traces, and can be handled, prepared and consumed by everyone, even the most sensitive.
