Q: What does the beneficial bacteria in yogurt do when you eat it?
A: Our digestive tracts depend on several strains of live, beneficial bacteria to function properly. The bacteria help break down food, making nutrients more available for absorption through the intestinal walls. These nutrients fight infestation from potentially harmful bacteria, yeasts, and viruses. Beneficial bacteria counts can greatly decline as we age, consume antibiotics, undergo chemotherapy, etc. Eating yogurt—or any cultured product—repopulates the beneficial bacteria in our systems. Yogurt can help protect us from invasions by other illness-causing microorganisms and makes nutrients in all the food we eat more available to our bodies.
