Cooking for a Family With Allergies and Different Diets

An allergy is a safety rule. If the allergen is on the plate, the person can be harmed, so a dish that contains it must not appear on the shared menu at all, and cooking two versions side by side raises the chance of a mix-up and of cross-contact. A diet or preference, such as vegetarian, halal or low-carb, is a different kind of rule: it decides what a person chooses to eat, and it can be met by adapting one dish for one person.

Mealyno's household planner follows exactly this split. Strict allergies from anyone at the table form a shared safe base for the whole menu, and everything else gets a per-person variant.

EU Regulation 1169/2011 lists 14 allergens that must be declared on food: cereals containing gluten, crustaceans, eggs, fish, peanuts, soybeans, milk, tree nuts, celery, mustard, sesame, sulphites, lupin and molluscs. In the planner you tick the allergens a person has and choose whether the rule is strict (an allergy or celiac disease, any hit blocks the dish) or a preference (avoid where possible, warn instead of block). The base menu has to satisfy the union of everyone's strict allergens.

We ran the planner's own ingredient dictionary over the English names and aliases of all 178 foods in our USDA-based dataset, once per allergen. "Contains" means the name names the allergen directly (egg, cheddar, almonds). "Check" means the name is ambiguous and would need a label. "No match" means the dictionary found nothing in the name. It reads names, not recipes or labels, so no match is never proof of safety.

Allergies add up. A table that must avoid all nine at once still has 103 of 178 dataset foods with no match, and the largest groups left are plain vegetables, fruit, grains and meat. That is the practical meaning of a shared safe base: the menu narrows, but it does not disappear, and the planner builds dishes from what is left.

Suppose a child has a strict peanut and tree nut allergy, one adult is vegetarian and the other eats everything. The strict allergy goes into the shared base, so no dish on the menu contains nuts: that removes 7 dataset foods that contain or may contain peanuts or tree nuts from the start. The vegetarian then gets an adapted version of any meat dish, for example beans or lentils in place of chicken, and that variant is checked against the whole table, so a variant built for the vegetarian can never carry the child's allergen. The third adult eats the base dish as written.

If no safe variant exists for someone, the dish is never served to that person. The plan marks it with a warning and sizes the sides for them instead.

A food name can hide an allergen. Flavourings with no named source, sauces, stock cubes, sausages and baked goods are common places where milk, egg, soy, gluten or mustard turn up. Cross-contact is a separate risk: a product with no allergen in its recipe can still say it may contain traces. Paste any ingredient list into the allergen label checker to see which ingredients match, and always read the packaging as well. The checker is a text matcher and cannot see what is not written.

A shared menu reduces mix-ups, but it is not a substitute for the advice of the allergist or doctor who diagnosed the allergy, and it does not make a kitchen allergen-safe by itself. For a severe allergy, follow your emergency plan. Custom words you type under foods to avoid are matched literally, so enter each spelling you want blocked. Mealyno plans are general information, not medical advice.
