Vittelio
Six switches, applied everywhere
During setup (and any time after, from the Profile tab) you can mark what you avoid: tree nuts & peanuts, fish & shellfish, dairy, gluten, vegetarian, or vegan. From then on, every replacement card, every alternative behind the Skip button, and every recipe suggestion is filtered against your choices — there is no separate “allergy mode” to remember.
The filter works at two levels: broad food-group rules first, then a scan of each recipe's actual ingredient list — including compound carriers that are easy to forget, like pesto (nuts), teriyaki and most soy sauces (wheat), or granola (often both).
Cautious on purpose
When a dish is ambiguous, Vittelio errs on the side of leaving it out. A stir-fry with soy sauce is excluded for gluten even though gluten-free soy sauce exists, because a suggestion you have to double-check isn't a helpful suggestion. That said, the filter is a convenience, not a guarantee — if you have a medical allergy, always check real product labels and ingredients yourself.
Still a real plan
Restrictions never weaken the honesty of the app. Your MIND score is computed exactly the same way for everyone — the filter only shapes which dishes get suggested. And the catalog is deep enough that even the strictest setting, fully vegan, still leaves a workable plan; the MIND pattern is largely plant-forward by design, though animal-food groups like fish and poultry naturally won't contribute points to a fully plant-based week.
