Anxiety can really impact our appetite. Some people crave more food when anxious or stressed. They can eat too much, chasing some temporary feeling of comfort or relief.
I don't know why but stress eating is a thing people do (I know I do!) or use food as a reward for things go well. Even in our own classrooms, when it's a holiday we have a party with treats or some teachers give candy as prizes. I wonder how we can reframe how we think of food, especially in the classroom.
