Allergies are health disorders that affect many people worldwide and can be closely related to the type of food we consume. When the body is exposed to certain food items, it may react abnormally, leading to various symptoms ranging from mild to severe. The types of food allergies vary greatly, including dairy, gluten, and nut allergies. Understanding the relationship between allergies and nutrition is crucial to avoid foods that trigger these reactions, such as fish, eggs, milk, types of chocolate, or when taking certain medications like penicillin, aspirin, and procaine. This can help improve the quality of life and overall health for individuals who suffer from these allergies.
Allergies have different types of disorders that arise from consuming certain foods, medications, or inhaling certain substances. Some of the most notable include:
- Digestive system disorders such as vomiting, liver and intestinal colic, and stomach ulcers.
- Respiratory system disorders such as shortness of breath, asthma, sneezing, and colds.
- Skin and mucous membrane disorders such as eczema and itching.
- Nervous system disorders such as headaches, dizziness, and depression.

These disorders occur when a foreign body encounters an antibody inside the body, leading to the release of a substance called "histamine," which affects sensitive parts of the body such as the skin, lungs, and mucous membranes, resulting in targeting or hypersensitivity.
Despite the danger of allergies, proper nutrition plays a positive and effective role in prevention, treatment, or alleviating their severity, provided that the affected individual adheres to a specific diet and follows necessary health guidelines.
