Grain allergy refers to an adverse immune response triggered by consuming grains. Grains are a staple food in many diets worldwide, but for some individuals, certain components within grains can provoke allergic reactions. The most common grains known to cause allergies include wheat, barley, rye, and oats, though other grains may also elicit allergic responses.

Symptoms:

Symptoms of a grain allergy can vary in severity and may include:

1. Skin Reactions: Such as hives, eczema, or itching.
2. Respiratory Issues: Including sneezing, runny or stuffy nose, wheezing, or difficulty breathing.
3. Gastrointestinal Problems: Such as abdominal pain, nausea, vomiting, diarrhea, or bloating.
4. Anaphylaxis: In severe cases, a grain allergy can lead to anaphylaxis, a life-threatening allergic reaction characterized by a sudden drop in blood pressure, difficulty breathing, and loss of consciousness.

Causes:

Grain allergies are primarily caused by the immune system mistakenly identifying proteins found in grains as harmful substances. When these proteins are ingested, the immune system releases chemicals like histamine, triggering allergic symptoms. The specific proteins responsible for grain allergies vary depending on the type of grain.
