Answer 1

The indigestible polysaccharides in human diets are known as dietary fiber or roughage, with cellulose being a common example. Dietary fiber aids in the digestive process, despite our inability to break it down into nutrient forms.

Step-by-step explanation:

Polysaccharides that cannot be digested by human digestive enzymes and therefore cannot be absorbed are known as dietary fiber, which is also referred to as roughage. These are primarily plant-based components such as cellulose, which humans cannot break down because the necessary enzyme, cellulase, is not produced by our bodies. Despite our inability to digest fiber, it plays an essential role in maintaining good digestive health by increasing the bulk of food and aiding in its passage through the gastrointestinal tract. While fiber does not supply direct energy or building blocks for the body, it is crucial for proper bowel management and to prevent constipation.

Answer 2

Polysaccharides that cannot be digested by human digestive enzymes, and therefore cannot be absorbed, are called fiber. It is a type of a carbohydrate that the body could not process or metabolize. It passes in the body as it is or undigested. Although, the presence of fiber is not really dangerous rather it is very helpful in regulating the use of the body of the sugars present and aid in keeping hunger and blood sugar at normal level. Daily recommended intake of fiber for both adults and children would be 20 to 30 grams to keep a good health. Sources of this are vegetable and whole fruits, grains and beans.
