Yes, it can be! In my opinion, this one is one of the biggest challenges I've faced, whether it’s been eating at restaurants or in other people’s homes.  While vegetarianism is more common these days and many restaurants have added plant options to their menus it can still be a challenge. It helps to research restaurants ahead of time when possible to make sure there is something you will be able to eat. Also, it helps to feel confident enough to ask the restaurant to leave something out of a particular dish or make a substitution. When eating meals in the homes of friends and family, you may need to communicate your needs to them to see if they can accommodate you. Also, you can also offer to bring something that is a dish you can eat but also one everyone else may enjoy too.
