This is definitely one of those elements of a wedding where you'll never be able to please everyone. But there are certainly things you can do and should keep in mind. Food can play a big part in a guest's enjoyment of a wedding. After all, not being able to eat during dinner time isn't very fun.

When creating RSVPs, include a spot for people to indicate any special dietary needs or allergies if none of your provided dishes will work for them. Example: most dishes served at weddings don't cater to gluten-free or vegan diets. Caterers can usually work with food limitations and can make a few special meals. Though, it may cost extra for you.

Don't stress too much about this. If your invitation RSVP doesn't include the option to notate which dietary needs a guest has, most guests with specific diets will plan food for themselves. So if this is one of those things that will be too much for you to plan, it won't destroy your wonderful reception. But if you're able, certainly do it.
