It is a type of carbohydrate that can't be digested by our body. It is that portion of plant that can't be completely broken down by digestive enzymes.It is essential because it slow the rate of sugar that is absorbed in bloodstream which keep your blood glucose level from rising too fast. resistant to enzymatic digestion.

Dietary Fiber

2.  Dietary Fiber also known as roughage, is the indigestible
portion of food derived from plants, which our body cannot
digest or absorb.
 It is type of a carbohydrate that helps keep our digestive
systems healthy.
 Sources:- It is found in edible plant foods such as cereals,
fruits, vegetables, dried peas, nuts, lentils and grains.

3. Types of dietary Fiber
 Fiber is commonly classified as soluble, which dissolves in water, or
insoluble, which doesn't dissolve.
Soluble Fiber
 Soluble fiber tends to slow the movement of food through the
Digestive System.
 It can help lower blood cholesterol and glucose levels.
 Soluble fiber is found in oats, peas, beans, apples, citrus fruits, carrots,
barley.
Insoluble Fiber
 Insoluble fiber tends to accelerate the movement of food through the
Digestive System.
 Whole-wheat flour, wheat bran, nuts, beans and vegetables, such as
cauliflower, green beans and potatoes, are good sources of insoluble
fiber.

4. Resistant starch
 Resistant starch is important in bowel health.
 Bacteria in the large bowel ferment and change the resistant
starch into short-chain fatty acids, which are important to
bowel health and may protect against cancer. These fatty
acids are also absorbed into the bloodstream and may play
role in lowering blood cholesterol levels.
 It is found in many unprocessed cereals and grains, under
ripe bananas, potatoes and lentils.

5. Benefits of Dietary Fiber
Prevent Constipation
 Insoluble dietary Fiber acts as a broom to sweep out the
digestive tract. It accelerates the passage of food through the
digestive system, which facilitates regular defecation.
 Adds bulk to the stool, which is easier to pass, hence
decreases the chance of constipation.
Lowers the Risk of Digestive Conditions
 A high-fiber diet may lower your risk of specific disorders,
such as Heartburn, Gastritis (Acidity), Hemorrhoids (Piles)
and Irritable Bowel Syndrome, etc.

6. Lowers the Blood Cholesterol Levels
 Soluble fiber may helps in reducing total blood Cholesterol
levels by lowering Low-Density Lipoprotein (LDL).
Controls the Blood Sugar Levels
 Dietary fiber, particularly soluble fiber, can slow the
absorption of sugar from the intestine.
Prevents Colorectal (Colon) Cancer
Weight Reduction
 Fiber helps you feel full longer because it stays in your gut
for longer periods of time.
 This helps to prevent overeating. High fiber diet is lower in
calories and fat. Fiber makes you chew food more, so you
tend to eat slower.

7. Lowers your Risk for Developing Heart Diseases
 High intake of dietary fiber lowers the risk of heart diseases.
 In a Harvard University study, researchers found that a high
dietary fiber intake has reduced 40 % risk of Coronary Heart
Disease.
