Allergen Education
Plant-based dining has grown dramatically. So has the assumption that vegan or plant-based menus are inherently safer for people with food allergies. They are not.

A guest with a tree nut allergy arrives at a plant-based restaurant. They see no meat, no dairy, no eggs. They assume the menu is safe. They order a cashew-based "cream" pasta. They have an anaphylactic reaction.
This scenario is not hypothetical. It is a well-documented pattern. The core problem is a misconception that has spread faster than the food trend that created it: that vegan food is food without allergens.
The truth is almost exactly the opposite. A heavily plant-based menu concentrates several of the most significant food allergens into almost every dish — because the protein sources, the fat sources, and the flavour systems that replace animal products in plant-based cooking are predominantly drawn from the nine major allergen groups.
Guests who assume plant-based menus are safe for their food allergies are not making an irrational inference. A guest with a milk or egg allergy — two allergens that are genuinely reduced in vegan cuisine — has good reason to feel more comfortable on a plant-based menu.
The problem is generalisation. A guest with a tree nut allergy reasoning "this is vegan, so it's safe for me" has made a logical error. A guest with a sesame allergy at a plant-based restaurant who does not ask about sesame because they assume the food is naturally allergen-free is exposed to real risk.
Research on plant-based diets and allergen risk has confirmed that many vegan substitute products are highly processed with extensive ingredient lists, and that because vegan food is not produced with food-allergic customers in mind, the cross-over between plant-based products and major allergens is frequent and often invisible to the consumer.
Restaurants with plant-based menus should actively communicate that plant-based food is not inherently safe for guests with food allergies. This communication should happen:
Every item on a plant-based menu is subject to the same allergen disclosure requirements as every other menu item under SB 68 and equivalent laws. There is no exemption for plant-based food. The soy-based protein, the cashew cream sauce, the tahini dressing, the sesame-crusted item — each one needs to carry its allergen disclosure.
Cashew cream is worth calling out because it is so widely used in plant-based cooking, often as an unlabelled component in pasta dishes, soups, and sauces. A guest with a tree nut allergy asking whether a dish contains dairy may be told "no" — which is accurate — while the dish actually contains cashew cream, which is a tree nut.
Staff training at plant-based restaurants must specifically address this: dairy-free does not mean tree-nut-free, and a guest asking about dairy should also be asked about tree nuts if the dish contains cashew or other nut-based alternatives.
Foodini's platform handles over 150 dietary profiles, including both allergen-based requirements and lifestyle preferences like vegan and vegetarian. The distinction matters operationally: a guest marking "vegan" is indicating a preference. A guest marking "tree nut allergy" is indicating a medical requirement that triggers different kitchen protocols.
Plant-based restaurants that conflate the two — treating all dietary requests through the same "can accommodate / cannot accommodate" framework — create a system that doesn't differentiate between the level of care required for a preference and the level of care required for an allergy.
The operators who get this right are the ones who resist the temptation to market their plant-based menu as inherently safer or more accommodating — because the marketing promise creates expectations that the reality of the ingredient list does not always support. Accurate allergen disclosure applied to every item on the menu, regardless of dietary format, is the only version of "accommodating" that is actually defensible.
Foodini covers all nine major allergens, all dietary preferences, and the full spectrum of plant-based ingredient complexity — so guests can filter by their specific allergy or dietary need and see exactly what is and isn't safe for them, regardless of menu format.
