I came across this article on hosting Thanksgiving dinners, but hey, these tips for hosts and guests alike may still come in handy what with the Christmas season rolling in.

Points number 2 and 16 refers to handling food allergies. For the host:

Ask about dietary restrictions when you make the invitation. If it's a small gathering, you will have to provide a dish for vegans or vegetarians. At larger parties with more food, they should be able to find enough food to make a meal. Ignoring nut or shellfish allergies is poor form.

For the guest:

If you have a special dietary need, delicately let the host know, but immediately offer to contribute a dish that you can eat. Never dictate to the host, though. If the offer is declined, respect it and hope for the best.

Enjoy the holidays, folks, and stay safe!
