Kidney beans
Here’s another normally healthy food that can be dangerous if eaten the wrong way. Red kidney beans are packed with protein, fiber and antioxidants, but eating them raw can wreak havoc on your stomach. “Uncooked kidney beans contain the toxin phytohemagglutinin, which can cause unpleasant gastrointestinal discomfort and symptoms similar to food poisoning,” says Dr. Davis. Make sure you boil kidney beans for at least ten minutes before eating them.
Hot dogs
Hot dogs aren’t the most nutritious food as it is, but eating them raw can be downright dangerous. It’s a common misconception that, since they’re pre-cooked, hot dogs can be eaten right out of the package like lunch meat. This isn’t the case at all. According to the FDA, packaged hot dogs can become contaminated with the bacteria Listeria, which can only be killed by reheating the dogs.
