28 million bottles of Yakult are enjoyed everyday throughout the world. Yakult contains probiotics or friendly bacteria or yeasts. These friendly microorganisms help maintain the natural balance of organisms in the intestines. Probiotics reduce the growth of harmful bacteria in the intestines and promote a healthy digestive system.

  3. 3. 3<br />What are probiotics?<br />Probiotics: pro = for<br /> biotics = relating to life <br /> = “for life”<br />↔Antibiotics<br /> “living microorganisms administered in adequate amounts which confer a beneficial health effect on the host”(Food and Agriculture Organization of the United Nations)<br />
  4. 4. Intestinal microbiota: group of microorganisms that live in the digestive tracts of humans and animals<br /><ul><li>inside the human intestine: over 100 trillion bacterial cells of over 100 different types of bacteria
