Is it correct to say that humans do not digest fiber? Discuss
That is correct. Humans do not possess the appropriate
digestive enzymes to break the types of chemical bond
found in fiber. Interestingly, bacteria in the large intestine
can and do break down dietary fiber. Thus, although
humans cannot digest fiber, some bacteria that reside in
humans can.

That night she feels a little nauseated and heads to bed early, forgetting the chicken on the counter. In the morning she has a mild case of diarrhea, but decides not to cancel the dinner party because she is feeling a little better than the
night before. She places the thawed chicken into a casserole dish and places it in the refrigerator. Three hours before the guests arrive she begins to prepare the meal. She first cooks rice and places it in a serving dish to cool. Next she cuts the chicken breast into strips on a cutting board, places the chicken back into the dish and then seasons it. While the oven is preheating she chops unwashed salad ingredients on the same cutting board where she cut the chicken, but uses a clean knife. She combines the salad and places it into the serving bowl. One hour before the guests arrive she places the chicken into the oven to bake. She stirs the rice and adds nuts and a few herbs.
