Consume More Fiber. You’ve probably heard about it. But do you know why fiber is beneficial to your health?

Dietary fiber is found mainly in vegetables, fruits, whole grains, and legumes. It’s desirable because it can alleviate or prevent constipation. However, fiber-rich foods can also bring many other health benefits, such as helping maintain a healthy weight and lowering your risk of developing heart disease, diabetes, and certain types of cancer.

Finding delicious foods that serve fiber is acceptable. Learn what fiber, it’s different types, what health benefits it offers, and how to add it to your diet in this article.

What Is Fiber?

Fiber is found in plant food. It’s also known as “bulk” or “roughage.” Fiber is obtained by eating:

What Is Fiber

  1. Fruits
  2. Veggies
  3. Whole grains
  4. Beans
  5. Lentils
  6. Nuts
  7. Seeds

Macronutrients are essential nutrients that your body requires (and utilizes) a large amount daily. Other macronutrients include:

  • Proteins
  • Cholesterol and fats
  • Water

Most fibers do not contain many calories and aren’t a source of nutrition by themselves. However, fiber can play vital functions within your body (more about this later).

How Much Fiber Do You Need To Take In Per Day?

As mentioned in the previous paragraph, fiber plays an important role in our body. But how much should you try to eat every day?

The National Academy of Medicine recommends consuming this amount of fiber every day:

  • Women aged 50 and less: 25 grams
  • Aged 51 and over: 21 grams
  • Men aged 50 and younger: 38 grams
  • Men aged 51 and over: 30 grams

There are no guidelines for grams of fiber per meal, but it is recommended that fiber-rich food be served with every meal.

Regarding the practical aspects of eating more during each meal, it’s helpful to identify foods rich in fiber and find some suggestions for incorporating these items into your daily diet.

Different Types Of Fiber

Fiber comprises non-starch polysaccharides like dextrins, cellulose, inulin, and lignin. They also include chitin, beta-glucans, pectin waxes, and oligosaccharides. 

Different Types Of Fiber

Insoluble and soluble can be described as two main fiber types in the diet.

Many high-fiber food items contain both insoluble and soluble fibers, so people are not required to consider the distinction. Instead, they can concentrate on their overall fiber intake.

  • Soluble Fiber

When dissolved, insoluble fiber creates an emulsion-like substance inside the stomach. The gel is then broken into pieces within the large intestine. Soluble fiber is a person’s source of calories.

Soluble Fiber

Soluble fiber offers the following advantages:

  • Lowering LDL cholesterol levels in the blood by affecting how the body absorbs fats from dietary sources and cholesterol
  • Slowing the absorption of additional sugars through digestion. This can benefit from regulating blood sugar levels.

Good sources of soluble fiber include:

  • Beans
  • Fruits
  • Oats
  • Nuts
  • Vegetables
  • Insoluble Fiber

Insoluble fiber doesn’t dissolve in water, and it passes through the digestive tract in a complete state of completeness. It doesn’t prepare calories.

Insoluble Fiber

Insoluble fiber can help build the bulk of stool, which helps a person get rid of stool faster. It may also help prevent constipation.

Insoluble fiber is a good source of nutrition Include:

  • Fruits
  • Nuts
  • Vegetables
  • Whole-Grain Food Items

Food Feeds  “Good” Gut Bacteria

The bacteria that reside in our bodies outnumber the body’s cells by 10 to 1. Bacteria are found in the mouth, on the skin inside the mouth, and in the nose; however, the vast majority are found within the gut, specifically the large intestinal tract.

Between 500 and 1,000 species of bacteria reside in the intestines, totaling 38 trillion cell count. These bacteria in the gut are called”gut flora.

This isn’t a negative thing. There’s a mutually beneficial connection between you and some of the bacteria in your digestive tract.

The bacteria give the bacteria food, shelter, and a safe place to live. In exchange, they benefit from certain aspects that a human body cannot handle alone.

The various kinds of bacteria are vital to multiple areas of health, such as blood sugar control, weight, immune function, and even brain functioning.

It is possible to wonder what this has to do with fiber. Like all living things, bacteria require food to fuel their bodies and function. The issue is that the majority of carbohydrates, proteins, and fats are absorbed into the bloodstream before reaching the large intestinal tract, leaving little room for the gut’s flora.

Human cells lack the enzymes required to process fiber, mainly unaltered and absorbed into the large intestine. But, the intestinal bacteria have enzymes that process a variety of fibers.

This is the primary reason why (some) food fibers are necessary for good well-being. They provide food for the “good” bacteria in the intestinal tract, acting as prebiotics. In this manner, they aid in developing “good” gut bacteria and can result in a myriad of positive effects on your health.

The beneficial bacteria provide nutrition for the body, including fatty acids with short chains like propionate, acetate, and butyrate, which is believed to be the most crucial.

These fatty acids with short chains nourish the cells of the colon, resulting in less gut inflammation and improvement in digestive conditions like IBS, Crohn’s disease, and ulcerative colitis.

If the bacteria ferment fiber, they release gasses. This is why high-fiber food intakes may cause stomach flatulence and stomach pain in certain individuals. These adverse effects generally fade after your body has adjusted.

Health Benefits of Fiber

Consuming sufficient fiber is an important element of a healthy diet. One study involving more than 4,600 people discovered that a fiber-rich diet reduced the risk of developing chronic illnesses by as much as 31%. Here are a few specific health benefits that fiber can bring to your body:

  • Regular Bowel Movements

Insoluble and soluble fibers both promote regular bowel movements and help prevent constipation. When soluble fiber dissolves in water, it creates gel-like substances. These aid in bulking and softening stool, making it easier to move. 

Additionally, they interact with the intestine’s inner lining, causing mucus and water to pass through the colon to facilitate colon movement.

Fiber can help maintain your regularity by providing your gut bacteria with food. When the bacteria in your digestive tract eat and digest the fiber, it is taken into your intestines, making your stool soft and more accessible.

A Lower Risk of Various Illnesses

Meeting the recommended daily fiber intake benefits several different areas of disease prevention. 

Incorporating satisfying fiber into your diet can decrease the chance of:

  • Heart Disease
  • Type 2 Diabetes
  • Colorectal Cancer

Heart disease is the No. 1 killer of Americans, so the cardiovascular benefits of fiber are one of the most important. Furthermore, 1 out of 10 Americans has Type 2 Diabetes, and the incidence of colorectal cancer is increasing.

  • Reducing The Risk of Diabetes

Adding more fiber to your diet could also benefit people with diabetes. Fiber can reduce the body’s sugar absorption and prevent blood sugar spikes following meals.

A 2018 review finds that those who consumed a diet high in fiber, including cereals, had a lower chance of developing the type 2 form of diabetes. The study also found that these individuals had a slight drop in blood sugar levels.

  • Reduced Risk of Certain Cancers

Although studies vary, the majority seem to suggest that consuming more fiber lowers the risk of developing cancer, including breast and colorectal cancers. 

For instance, in a review of 2020 published in the American Journal of Clinical Nutrition, researchers discovered that a higher intake of fiber specifically, particularly the fiber within whole grain products, is linked with a lower chance of getting colorectal cancer. 

Another review, published in Cancer in 2020, found that soluble fruit fibers have the strongest association with a lower chance of developing breast cancer. 

This aligns with the American Cancer Society’s guidelines for a diet rich in total fiber, which would include vegetables, fruits, and whole grains.

The Connection Between Cholesterol And Fiber

The apparent value of fiber is evident in its capability to reduce cholesterol levels. A study showed that diets high in fiber and plant-based decreased LDL cholesterol (“bad” cholesterol) by one-third. 

However, this quality could be more effective. 

A lot of substances known to cause harm can lower cholesterol. High cholesterol isn’t usually an issue — but when it’s a problem, it is typically a sign that something more fundamental is at play.

What Is The Relationship Between Fiber Consumption And Weight Loss?

The research into the connection between fiber consumption and weight loss could have been more impressive. Many studies have yielded mixed results, and the ones showing benefits are poorly designed.

Even the most prominent, pro-fiber researchers observe that “The limited number of clinical trials comparing high-fiber foods with low-fiber foods have not provided consistent data indicating that these diets are more efficacious for weight loss than low-fiber control diets.” 

Contrary to the belief that fiber benefits, some kinds of fibers can cause satisfying discomfort and bloating to hinder weight loss. 

A widely used food additive and fiber supplement known as guar glycerin has been linked to stomach pains, flatulence, stomach cramps, diarrhea, and many more.

Fiber may make you feel fuller for longer without additional calories.

If you’re overweight or obese, fiber could be a great choice to benefit from losing weight. 

The study of 240 adults eating 30 grams of fiber shed weight and maintained it for a year. In a meta-analysis of 12 studies, those who ate more fiber for between 2 and 17 weeks had a smaller weight loss and shed the most body fat than those who did not.

A 2001 study looking into guar gum as a weight loss aid concluded that “Guar gum isn’t effective in reducing body weight. 

Given the potential adverse reactions to its use, the dangers of consuming Guar gum far outweigh the advantages. Guar gum should not be considered a remedy for reducing one’s body mass.

 We also see the fiber myth dispelled.

Do You Have To Eat Foods High In Fiber or Take Supplements?

Getting minerals, vitamins, and other essential nutrients from your diet is important, and fiber is no different.

It’s important to get fiber from various fruits, vegetables, whole grains, beans, and legumes to have a healthy and balanced diet/

The following four food categories are rich in fiber:

  • Legumes: Beans, lentils, lima beans, dried peas, etc.
  • Whole grains: Whole wheat products, bran, steel-cut oats, barley, rolled oats, brown rice, quinoa, corn, rye.
  • Fruit: Apples, berries, oranges, pears, plums, bananas, etc.
  • Vegetables: Brussels sprouts, broccoli, cabbage, green beans, squash, potatoes, sweet potatoes, spinach, etc.

If you’re having difficulty finding a suitable one for the food you consume, your healthcare doctor may suggest a Moa supplement. 

Food is the perfect source of fiber, but supplements can be beneficial if you can’t get adequate amounts through diet.

Make sure you speak with a health professional before taking any supplements, including fiber.

Tips to Boost Your Fiber Intake

There are a lot of famous (and delicious!) food items that are high in fiber and many ways to include them in your diet. Here are a few suggestions to think about during your day:

  • For breakfast, try steel-cut oatmeal or rolled oats and whole wheat cereal, which have at least 5 grams of fiber. You can also top it off with fruits like blackberries or raspberries.
  • Lunch: Serve lentil or bean soup and sandwiches on a hearty whole-wheat loaf.
  • Dinner: Offer a nutritious portion of salad or vegetables and a whole-grain accompaniment such as brown rice, whole wheat bulgur, pasta, or quinoa.

You can also sprinkle bran, ground flaxseed, or chia seed into soups, cereals, spaghetti sauce, casseroles, or yogurt. They add a big hit of fiber without changing much in taste.


Fiber is a form of carbohydrate your body can’t process. Two types of fiber, insoluble and soluble, benefit your health.

Consuming sufficient fiber is beneficial to your health. Fiber can improve gut and heart health, control blood sugar levels, decrease cancer risk, and reduce weight.


What Is The Role of Fiber In The Body?

What Is Fiber’s Role In The Body? Fiber is primarily carbohydrates. Its primary function is to keep the digestive system in good health. Other terms that refer to dietary fiber include “bulk” and “roughage,” which can be confusing since certain types are water-soluble and aren’t rough or bulky in any way.

Is It Reasonable To Have Fiber Every Day?

The American Heart Association Eating Plan recommends eating a variety of food sources of fiber. The total amount of fiber consumed by a person should be between 25 and 30 grams per day, derived from food sources, not supplements. Adults in the United States consume about 15 grams of dietary fiber daily, less than half the recommended amount.

Why Do Doctors Recommend Fiber?

Why Do Doctors Recommend Fiber? Research suggests that incorporating more fiber into your diet can be a factor in treating conditions like gastrointestinal diseases, hemorrhoids, constipation, excessive cholesterol, heart disease, diabetes, stroke, and some types of cancer. Most Americans must get the recommended fiber (25 to 35 grams).

What Organs Does Fiber Help?

Fiber can cause changes in the gut chemistry and improve intestinal barrier function, which shields the kidney and liver from the transfer of proinflammatory bacteria and bacterial products.

What Is The Drawback Of Having Too Excessive Fiber?

What Is The Drawback Of Having Too Excessive Fiber? High-fiber foods are great for your overall health. However, consuming excessive fiber at once can cause intestinal gas, constipation, abdominal bloating, and cramping. Incorporate more fiber into your diet slowly over a couple of weeks. This will allow the bacterial community within your digestion system to adapt to the changes.
