Special dietary requirements refer to restrictions or modifications in a person’s diet, often due to health issues, allergies, personal beliefs, or cultural and religious practices[7]. These requirements can range from the exclusion of certain ingredients due to allergies (such as nuts, dairy, or gluten) to lifestyle choices like vegetarianism or veganism, and also include religious dietary laws such as halal or kosher[1].
Common types of special dietary requirements include:
- Gluten-free and Coeliac: Essential for those with coeliac disease, gluten intolerances, or wheat allergies. Common foods to avoid include bread, pasta, cereals, and baked goods containing wheat, barley, or rye. Alternatives like rice, quinoa, and certified gluten-free products are recommended[1][4][6].
- Dairy-free and Lactose-free: Needed by individuals with lactose intolerance or dairy allergies. Key foods to avoid are milk, cheese, yogurt, and butter, with alternatives such as almond milk or lactose-free cheese[1][4][6].
- Vegetarian: Excludes meat, fish, and poultry. Some vegetarians also avoid animal by-products like gelatin or rennet[1].
- Vegan: Excludes all animal products, including dairy, eggs, and honey. Vegan diets require careful planning to supply all essential nutrients[1].
- Paleo: Focuses on unprocessed foods and eliminates grains, legumes, and dairy[1].
- FODMAP: Follows the restriction of specific carbohydrates known to trigger digestive symptoms, particularly for those with IBS[1].
- Tree nut and peanut allergies: Requires thorough avoidance of nuts in any form to prevent potential allergic reactions[1].
- Fish and shellfish allergies: Necessitates complete exclusion of all related seafood[1].
- Ketogenic (Keto): High-fat, low-carbohydrate diet, sometimes prescribed for certain metabolic conditions[1].
- Religious requirements: Such as halal or kosher, which impose rules on the types of permissible foods and preparation methods[1][5].
- Diabetes: Involves regulation of carbohydrate and sugar intake to maintain stable blood glucose levels[2][7].
Other health conditions that may require specific dietary interventions include:
- Heart disease: Diets low in saturated fat and cholesterol, and high in fiber are often advised[2].
- Celiac disease: Absolute gluten avoidance is necessary to prevent serious digestive symptoms[2].
- Colitis and Crohn’s disease: May require a low-residue or specifically tailored diet to manage inflammation[2].
- Hypoglycemia: Requires regular intake of balanced carbohydrates to avoid low blood sugar levels[2].
It’s vital for those planning meals—such as caterers, event organizers, or restaurant staff—to accurately identify and address these requirements to ensure every person’s health, safety, and inclusion. Consulting with medical professionals or dietitians is always advised when managing complex dietary needs[1].
