When we say something is "taboo," it means that people don't usually eat that thing. Some common examples of taboo foods might be insects or animals that are usually kept as pets, like dogs or cats. Other foods might be taboo because of cultural or religious beliefs, like pork for some people who follow certain religions.
While some people might find taboo foods to be gross or weird, it's important to remember that different cultures and groups of people have different beliefs about what is and isn't okay to eat. It's always important to be respectful of these beliefs and understand that what might be taboo for one person could be totally normal and delicious to someone else.
