which of the following statements are true about fiber? more than one answer may be correct.
□ provides about 9 kcal per gram
□ adds bulk to the feces
□ not digestible by human enzymes
□ made of many sugar units bound together

Explanation:

• Fiber is a complex carbohydrate, so it consists of linked sugar units.
• Humans lack enzymes to break down most dietary fiber, so it is indigestible by human enzymes.
• Fiber adds bulk to feces, aiding in digestive regularity.
• Fats provide ~9 kcal per gram; fiber provides little to no caloric value to humans as it is not digested.

Answer:

• not digestible by human enzymes
• adds bulk to the feces
• made of many sugar units bound together
