Answer to Question 1
Prebiotics: food components (such as fibers) that are not digested by the human body but are used as food by the GI bacteria to promote their growth and activity.

Answer to Question 2
The idea that people should not eat certain food combinations (for example, fruit and meat) at the same meal, because the digestive system can- not handle more than one task at a time, is a myth. The art of food combining which actually emphasizes food separatingis based on this myth, and it represents faulty logic and a gross underestimation of the body's capabilities. In fact, the contrary is often true; foods eaten together can enhance each other's use by the body. For example, vitamin C in a pineapple or other citrus fruit can enhance the absorption of iron from a meal of chicken and rice or other iron-containing foods.
