It’s yogurt’s activity in the gastrointestinal tract that makes it one of our SuperFoods. A healthy digestive system is critical to good health. Our ability to absorb nutrients from our food depends on our GI health. Even if we eat the most nutrient-dense foods in the world, if our digestive ability is impaired, we won’t be getting the full benefits of a healthy diet. As we age, the efficiency of our digestive system is often diminished. All the more reason to rely on yogurt as a food that will promote and help preserve intestinal health.
