Try being a vegetarian at least one day a week. A vegetarian is in some ways healthier than being a meat eater. Even if you are not ready to make a leap to complete vegetarianism, you can get some of the benefits of a vegetarian diet by taking a break from meat completely one day every week. For optimal health, include foods in your daily diet that contain probiotics. Probiotics are the good bacteria that live inside your body. They aid in digestion and the proper break-down of foods so your body can absorb the nutrients efficiently. They work against the bad bacteria that sometimes invade your digestive system and cause diarrhea.
