How can bacteria be good for us?
Some kinds of bacteria do cause illnesses and disease in humans. “Strep” throat is an example of an illness caused by bacteria. However, the majority of bacteria do not cause disease. In fact, there are types of bacteria that are actually beneficial. “Good” bacteria, known as probiotic bacteria, are used in the manufacturing of food and beverages. Some examples of foods that have probiotic food ingredients are buttermilk, yogurt, cheese, sausage, and acidophilus milk. These same kinds of probiotic bacteria are present in our intestines and help to keep the digestive system running by digesting food and processing waste.
