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

Explanation:

• Fiber is a type of complex carbohydrate that adds bulk to feces, aiding in digestion.
• Humans lack the enzymes needed to break down most dietary fiber, so it passes through the gut undigested.
• Fiber is composed of linked sugar units (polysaccharides).
• Fats provide ~9 kcal per gram, while fiber provides little to no usable calories for humans.

Answer:

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