What can a person with stomach bacteria eat?

If you are saying that you have the stomach flu( AKA Salmonella ) then you can eat small portions of food( mostly bread products such as noodles or plain simply bread, I usually eat ramen noodles lol ) after you have thrown up. If you have not thrown up, or your chances of throwing up are slim, you may eat whatever you want whenever you want, but stay away from citris like foods such as Orange Juice, starbursts, Lemons, ETC. I hope I answered your question...
Hope my answer helped :)
