Food Profiles is designed to save time when shopping by making it easier to understand what can and cannot be eaten according to your dietary needs. At the moment, it is not integrated with our substitution process.
We never want you to go without, so when an item is out of stock we try to provide the next best alternative. If you don't want to accept our suggestion, that's fine! Just let your driver know and they'll remove this from your final order total. For more information on substitutions take a look at What happens if something I've ordered has to be substituted? in our FAQs.
