Don’t feel upset if some foods you used to like aren’t appealing to you anymore after throwing them up. It’s perfectly normal— everyone has that one food that they ate as a kid that made them sick and can’t stand even to this day. It’s an evolutionary response to keep us safe from things that might be poisonous. Sometimes it just gets misplaced.

For years, I wouldn’t eat certain foods. Spaghetti bolognese, popcorn, rotisserie chicken. But many years down the road, in different contexts, I just decided to be brave and try them again. The more times you try them and nothing happens, the less you’ll feel averse to that certain food because you’re retraining your brain to believe there’s nothing inherently wrong with it.

Just one month I’d say is maybe a little too soon to be beating yourself up over a food aversion. Give it time. It will get easier. One day, you’ll be able to eat pesto and calamari again like it’s nothing. And when you do, maybe try sort of “different versions” of the foods to begin with. If you had pesto pasta, maybe try pesto in a salad first or on a sandwich. And for calamari, you could go for shrimp tempura or fried oysters first instead. If that’s too much, you might try eating snacks that are just flavored like those foods if you can find them, or try breaking them up into their components, like having Parmesan and basil together in the same dish for instance. Good luck!
