Probiotics, which mean “for life,’ are beneficial bacteria that can assist your body with digestion and help protect you from harmful bacteria.
There are, in fact, trillions of bacteria in your digestive tract, but not all of them are good for you. One reason why probiotics are so important is because they help keep the balance of good vs. bad bacteria in check. Without them, bad bacteria would overwhelm your system, causing your cells to miss out on important nutrients and function poorly.
As written in the book “Digestive Wellness”, probiotics lower the pH of your colon and kill disease-causing microbes. They also produce vitamins A, B and K, protect you from illness, enhance peristalsis, and make lactase for milk digestion. Probiotics also ferment dietary fiber, producing important short-chained fatty acids, such as butyric acid, which in low levels has been associated with ulcerative colitis, colon cancer, active colitis and inflammatory bowel disease.
