Perhaps the most fascinating aspect of the gastrointestinal tract is the friendly bacteria it employs to maximize the nutritional benefits of the food you eat. There are over three pounds of these little microorganisms that not only help to break down certain substances that escape digestive fluids, but also to manufacture healthful compounds that are reabsorbed into the blood. Deficiencies of these friendly bacteria are not uncommon due to sickness, bad eating habits and antibiotic use. Fermented foods, such as yogurt and kefir, provide some of these friendly bacteria, but probiotic supplements contain much greater amounts.
