Thanks for the suggestions. I managed to eat and keep down bananas, bread, pasta, and rice with vegetables. Now thinking about the 3 last items makes me nauseous though. It seems like I always have to eat something else.

To others suffering from the same disease and finding this: it’s recommended to avoid fruit juices high in sugar.

It is not recommended that you stop eating. It will not reduce the symptoms of gastroenteritis, does not provide enough calories and can delay healing.
