How soon can i eat solid food after food poisoning?

Diarrhea subsides: Stay on clear liquids until the diarrhea subsides. It is important to avoid dehydation so liquids are a must. After the diarrhea stops, go back slowly over a 24 hour time span using toast, fruits.Avoid vegetables, nuts and legumes for a few days after food poisoning since their high-fiber content makes them difficult to digest, and they can cause gas. Spicy foods and sauces can also aggravate.
