Definition

Noun A special eating plan that excludes specific foods or ingredients to which a person has a known allergic reaction. Its primary purpose is to prevent allergic symptoms and promote health by avoiding dietary triggers.

Usage

An "allergy diet" is prescribed or adopted to manage a food allergy. It requires the individual to carefully read food labels and be aware of ingredients in prepared foods to avoid the allergen completely.

Examples

• After her diagnosis, she followed a strict allergy diet that excluded all nuts and dairy products.
• The doctor recommended an allergy diet to identify which food was causing the skin rash.
• Maintaining an allergy diet when eating at restaurants requires clear communication with the kitchen staff.

Advanced Usage

• The term is often used in medical and nutritional counseling contexts. It implies a deliberate, restrictive dietary pattern for therapeutic reasons, distinct from a choice-based diet like a vegetarian diet.

Variants and Related Words

• Elimination diet: A similar diet where foods are removed and then systematically reintroduced to identify allergies or intolerances. An "allergy diet" is often a long-term result of an elimination diet.
• Hypoallergenic diet: A diet designed to minimize the risk of an allergic reaction.

Synonyms

• Exclusion diet
• Allergen-free diet

Notes on Meaning

• The term specifically refers to avoiding allergens, not foods disliked or avoided for other health, ethical, or religious reasons (e.g., gluten-free for celiac disease is a medical necessity but not typically called an "allergy diet" unless a wheat allergy is present).
• It is a compound noun where "allergy" modifies "diet" to specify the diet's purpose.

Noun

1. a diet designed to avoid the foods that you are allergic to
