When you have food poisoning, you should drink plenty of liquids to replace lost fluids and electrolytes. You may vomit after you eat or lose your appetite for a short time. When your appetite returns, you can most often go back to eating your normal diet, even if you still have diarrhea.

When children have food poisoning, parents and caretakers should give children what they usually eat as soon as their appetite returns. Parents and caretakers should give infants breast milk or formula as usual.
