To be "wary" means to feel cautious or on your guard because of potential problems or dangers. In this video, "maybe you're wary of ... these compounds in your food" means "maybe you feel cautious/nervous about these compounds in your food." Ex: Children are taught by their parents to be wary of strangers. Ex: I'm wary of walking around alone at night. It can be dangerous.
