Why
Classic salted Lay's is potato, oil and salt. Beyond that, cheese, sour cream, chicken and barbecue seasonings frequently contain whey, milk powder or animal flavourings. Walkers (the same company in the UK) has historically used milk in Ready Salted seasoning at times, so read the pack.

- "May contain milk" is an allergen cross-contamination note, not an ingredient — most vegans still buy it

Questions people ask
Is Lay's crisps certified vegan?
Certification is separate from the recipe. Many products with no animal ingredients carry no vegan mark because the maker will not rule out shared production lines. Check the pack for a registered vegan trademark, and treat the ingredient list as the primary evidence.
Does the answer change between countries?
Often, yes. The same brand name can use different fats, emulsifiers, colours or whey depending on the plant that made it, so always read the local label rather than an answer written for another market.
