We're not currently able to tailor the recipes in line with specific allergies or intolerances. But the meal plans have been designed to include a large number of recipes each month with as much choice as possible. There is also a Create Your Own tool, which allows you to build your own meals using tailored ingredients, giving more flexibility in your meal plan.
For lots of recipes you can simply swap out a certain ingredient for an alternative, but there may be some recipes where a swap wouldn't work (i.e. it may impact taste, texture or tailoring). This may also be the case if needing to make multiple ingredient swaps. In this instance it would be a case of opting for a different recipe. As you progress through each cycle, the number of recipes in your app will grow so you should have plenty of meals to choose from.
If you're unsure about how your specific allergy/ intolerance would effect the plan, feel free to get in touch with the Support Team for further guidance.
