What Is The Role Of Fiber In The Diet – Katherine Marengo LDN, R.D. Medically reviewed by, Nutrition – By Kris Gunnars, BSc – Updated April 21, 2023
Certain types of fiber may benefit health, including the gut microbiota, blood sugar, and colon walls.
What Is The Role Of Fiber In The Diet
Growing evidence shows that eating enough fiber can improve digestion and reduce the risk of chronic disease.
The Importance Of Fiber In One’s Diet
Many of these benefits are mediated by the gut microbiome, the millions of bacteria that live in your digestive system.
Perhaps a more useful way to classify fiber is whether it is fermentable or non-fermentable, meaning whether or not friendly gut bacteria can use it.
It is important to remember that there are different types of fibers. Some of them have important health benefits, while others are mostly useless.
There is also an overlap between soluble and insoluble fiber. Some insoluble fiber can be digested by good bacteria in the gut, and most foods contain both soluble and insoluble fiber.
The Role Of Fiber In Weight Loss
Bacteria living in the human body outnumber the body’s cells by a ratio of 10 to 1. Bacteria live on the skin, mouth, and nose, but the vast majority live in the gut, primarily the large intestine (
Five hundred to a thousand different types of bacteria live in the gut, totaling about 38 trillion cells. These intestinal bacteria are also known as intestinal flora.
This is not a bad thing, in fact, there is a mutually beneficial relationship between you and certain bacteria that live in your digestive system.
Provide food, shelter and a safe habitat for the bacteria. Instead, they take care of some things that the human body cannot do on its own.

Among the different types of bacteria, some are critical to various aspects of health, including weight, blood sugar control, immune function, and brain function (
You may wonder what this has to do with fiber. Like any other organism, bacteria must eat for energy to survive and function.
The problem is that most carbohydrates, proteins and fats are absorbed into the bloodstream before reaching the large intestine, leaving little for the intestinal flora.
This is where fiber comes into play. Because human cells lack the enzymes to digest fiber, it reaches the large intestine relatively intact.
The Role Of Fiber In A Healthy Diet
This is the most important reason why (some) dietary fiber is essential for health. They act as prebiotics, feeding the “good” bacteria in the gut (
In this way they promote the growth of “good” intestinal bacteria, which can have various positive effects on health (
Friendly bacteria produce nutrients the body needs, including short-chain fatty acids such as acetate, propionate, and butyrate, butyrate appears to be the most important (
These short-chain fatty acids can nourish gut cells, leading to reduced gut inflammation and improvement in digestive disorders such as irritable bowel syndrome, Crohn’s disease, and ulcerative colitis.

As the bacteria ferment the fibers, they also produce gas. This is why fiber-rich foods can cause gas and colic in some people. These side effects usually disappear over time as the body adapts.
Summary Consuming adequate amounts of soluble and fermentable fiber is critical to optimal health because it optimizes the activity of friendly bacteria in the gut.
In fact, some studies show that increasing dietary fiber can automatically lead to weight loss by reducing calorie intake (
Fiber absorbs water in the gut, slows nutrient absorption and increases feelings of satiety (
Importance Of Protein & Fiber In Diet
However, this depends on the type of fiber. Some types have no effect on weight, while some soluble fiber can have a significant effect (
Summary Some types of fiber can help you lose weight by increasing feelings of satiety and reducing calorie intake.
High-fiber foods have a lower glycemic index than refined carbohydrate sources that have been stripped of most of the fiber.
This is especially important if you follow a high-carb diet. In this case, fiber and carbohydrates can reduce the likelihood of raising blood sugar to harmful levels.
Debunking The Myth:
That said, if you have blood sugar problems, you should consider reducing your carbohydrate intake, especially eating refined, low-fiber carbohydrates like white flour and added sugar.
Summary Foods high in viscous fiber have a lower glycemic index and cause smaller blood sugar spikes than low-fiber foods.
A review of 67 controlled studies found that consuming 2-10 grams of soluble fiber per day lowered total cholesterol by 1.7 mg/dL and LDL (bad) cholesterol by 2.2 mg/dL on average.
But this also depends on the viscosity of the fiber. Some studies have found significant reductions in cholesterol with increased fiber intake (
Should Someone With Ibd Include Or Avoid Fiber In Their Diet?
Although many observational studies show that people who eat more fiber have a lower risk of heart disease, it is not known whether this has significant long-term effects (
Summary Certain types of fiber can lower cholesterol levels. However, many studies show that, in general, the effect is not very large.
Fiber is believed to help absorb water, bulk up the stool, and speed up the movement of stool through the intestines. However, the evidence is quite mixed (28,
Some studies show that increasing fiber can improve constipation symptoms, but other studies show that eliminating fiber improves constipation. Effects depend on fiber type.

In a study of 63 people with chronic constipation, following a low-fiber diet solved the problem. People who ate a high-fiber diet saw no improvement (
In general, fiber that increases the water content of the stool has a laxative effect, while fiber that adds to the dry mass of the stool without increasing the water content has a constipating effect.
Soluble fiber forms a gel in the digestive tract and is not fermented by intestinal bacteria. A good example of gelling fiber is psyllium (
Other fibers, such as sorbitol, have a laxative effect by drawing water from the colon. Plums are a good source of sorbitol (

Choosing the right type of fiber can fight constipation, but taking the wrong supplements can have the opposite effect.
Summary The laxative effects of fiber vary. Some fibers reduce constipation, while others increase it. This seems to depend on the individual and the fiber type.
Many studies have linked high fiber intake to a reduced risk of colon cancer (
However, fiber-rich foods such as fruits, vegetables, and whole grains contain other healthy nutrients and antioxidants that may influence cancer risk.
The Role Of Fiber In Fatty Liver Disease
Therefore, it is difficult to isolate the effect of fiber from other factors in a healthy, whole foods diet. To date, there is no clear evidence that fiber has anticancer effects (
However, since fiber can keep the colon wall healthy, many scientists believe it plays an important role (
Summary Studies show that a high-fiber diet reduces the risk of colon cancer. However, correlation is not the same as causation. To date, no studies have confirmed that fiber has direct cancer prevention benefits.
Not only does it feed gut bacteria, fermentable fiber also makes short-chain fatty acids that nourish the gut wall.

In addition, viscous and soluble fiber can suppress appetite, lower cholesterol levels, and reduce blood sugar spikes after high-carbohydrate meals.
If you’re aiming for a healthy lifestyle, try to get a variety of fiber from whole fruits, vegetables, and whole grains.
