HUMAN NUTRITION

Detailed explanation-1: -Fiber is a type of carbohydrate that the body can’t digest. Though most carbohydrates are broken down into sugar molecules called glucose, fiber cannot be broken down into sugar molecules, and instead it passes through the body undigested.

Detailed explanation-2: -Fiber is the indigestible part of plant foods, including fruits, vegetables, whole grains, nuts and legumes. When you consume dietary fiber, most of it passes through the intestines and is not digested. For good health, adults need to try to eat 25 to 30 grams of fiber each day.

Detailed explanation-3: -Cellulose is the fibrous, indigestible form of plant carbohydrate. It is important because it provides bulk in the digestive tract and causes regular bowel movements.

Detailed explanation-4: -The more indigestible carbohydrates (oligosaccharides, dietary fibre and resistant starch) provide little energy but they still have important effects on our health.
