Let your stomach settle. After you experience the most explosive symptoms of food poisoning, like vomiting, diarrhea, and upset stomach, experts recommend letting your stomach settle. That means avoiding food and drink altogether for a few hours. Liquid intake is crucial for helping your body fight off food poisoning.
Vomiting and diarrhea can cause dehydration, so sucking on ice chips or taking small sips of water is a good starting point. Sports drinks that contain electrolytes are the best way to prevent dehydration during this time. When you feel you might be able to hold down food, eat foods that are gentle on your stomach and gastrointestinal tract. Stick to bland, low-fat, low-fiber foods.
