Eating just a few raw beans can make you so sick you have to go to the hospital.

If a kid gets sick with vomiting and diarrhea right after eating beans, and no one else got as sick, and they don’t have a fever, it might be from the beans—not a virus.

Eating kidney beans that weren’t cooked long enough can make a child very sick—vomiting, passing out, and having very low blood pressure and kidney problems—because of a natural poison in the beans.

Even though raw beans can make you sick, eating cooked beans doesn’t cause gut problems or inflammation in healthy people.
