    • A. 

      True

    • B. 

      False

  • 16. 
    If we can't digest cellulose, why is it good to eat?
    • A. 

      We call this fiber, and it helps food pass more easily through our digestive tracts because it abrades (irritates/slightly scrapes) the lining of the digestive tract, stimulating it to produce more mucus.

    • B. 

      It takes a long time to break down cellulose. This allows the cellulose to last much longer, and thus gives us a constant supply of energy rather than a quick burst of sugar.

    • C. 

      Because it tastes like sugar, so we fool our bodies into thinking we ate sugar, thus increasing our metabolism. However, it provides no calories for us, so it can help us obtain or maintain a healthy weight.

    • D. 

      Option 4
