It is one of the most important nutrients in the diet. It is also known as roughage.

Fiber is the non-digestible part of plant-based foods. Generally, it is mostly present in whole grains, lentils, fruits and veggies. It has several health benefits from the gut to the heart.

Fiber is a complex carbohydrate in nature and not digested by human gut cells. But it can be digested by the gut flora or microbiota present in the digestive tract and produces the benefits.

So, let’s explore the various health benefits and many more about dietary fiber.


Types of Fiber


Dietary fiber is generally two types: i) Water-soluble fiber and ii) Water-insoluble fiber.

1. Soluble fiber

This type of fiber can dissolve in water and form a gel-like substance in the gut. By the gut-friendly bacteria, this gel-like substance can be metabolized. It provides some amounts of calories to the individuals.

Soluble fiber provides some health benefits. It reduces the absorption of carbohydrates (or sugar) in the body and helps to regulate blood sugar levels.

On the other hand, it also reduces blood cholesterol levels by affecting dietary fat absorption.

The sources of soluble dietary fiber are oatmeal, fruits, nuts, seeds, veggies etc.


2. Insoluble fiber

It does not dissolve in water and mostly has intact in the gut. It passes through the digestive tract and remains unmetabolized. It does not provide any calories.

Insoluble fiber plays a supportive role in the digestion. It adds bulk to the stool and helps to pass it easily. That means, it can prevent constipation.

The sources of insoluble fiber are whole grains, peel of various fruits and veggies, nuts etc.

However, fiber can be categorized as fermentable vs. non-fermentable fiber. This category refers to whether gut-friendly bacteria can use or not.



  Recommended Daily Intake


The recommended daily intake amounts of dietary fiber are needed to know. According to the Academy of Nutrition and Dietetics, the recommended daily intake is 21-25 gm for men and 30-38 gm for women.

During pregnancy or breastfeeding, at least 28 gm of fiber must be needed on a daily basis for women.

But only 5% of the total population consumes the adequate recommended intake.

However, it has various health benefits, but eating too much fiber can cause some side effects also, such as gas, indigestion, bloating, constipation etc.

More than 70 gm fiber per day, consumption exerts the side effects.

A healthy gut is crucial to maintaining a healthy body. There are several benefits of dietary fiber present to keep a healthy gut.

About 100 trillion, 500 different species bacteria live in our digestive system, both good and bad. They are collectively known as the gut microbiota.

Good bacteria are essential, as they produce nutrients like acetate, butyrate, and propionate. Our body needs these short-chain fatty acids for optimal functioning.

Human cells cannot digest fiber, but good bacteria can. Fiber reaches your large intestine almost unchanged, where these bacteria feed upon them. In this way, fiber produces short-chain fatty acids and promotes the growth of good bacteria.

That means dietary fiber acts as a prebiotic and supports friendly gut bacteria.

So, the fiber in our diet keeps our gut healthy by increasing the population of good bacteria. This is the reason health experts tell you to follow a well-balanced high-fiber diet.

Generally, Insoluble fiber is believed to help transition the food into your digestive tract faster and responsible for relieving constipation.

But, according to some experts, soluble fibers are more effective in relieving constipation. This is because they are not fermented by gut bacteria and form a gel in the digestive tract.

Psyllium is one such soluble fiber that promotes bowel movement in the intestine and prevents constipation. Sorbitol also has a laxative effect, as it draws water into the colon.

The fiber in citrus fruits and legumes increases the growth of colonic flora. This in turn increases the stool weight, promoting healthy bowel movements.

Wheat bran’s high fiber content acts as a natural laxative and relieves constipation.

Besides constipation, dietary fiber has positive impacts on other gastrointestinal disorders, such as hemorrhoids, GERD, colon ulcers, Hiatal hernias etc.


iv. Fiber Reduces Blood Sugar Spike


Dietary fiber can stabilize blood sugar levels even after a high-carb meal. If a high carb diet has become your daily habit then try to add lots of fiber in your meal.

Simple carbohydrates affect blood sugar levels faster than fat or protein. If you eat a carb meal higher than what your insulin supply can handle, your blood sugar level rises.

Simple carbohydrates (or sugar) have a high glycemic index, whereas complex carbohydrates and high fiber foods have a lower glycemic index.

Fibers are also complex carb in nature, they slow down the absorption process of simple carbs or sugar in the intestine and lower the blood sugar spike. Additionally, it improves the body’s response to insulin. By increasing insulin sensitivity, high dietary fiber diets may also help prevent type-II diabetes.

If you’re having blood sugar issues, following a high fiber diet with complex carbs may help in the long run.
