17 High-Fiber Foods You Must Include In Your Diet

You probably already know this: A healthy diet always includes high-fiber foods in it.

Most people are familiar with fiber in terms of its constipation relieving effects. But, the superpower of fiber doesn’t end here.

It can reduce the risk of various diseases, such as heart disease, type 2 diabetes, and a few cancers. Fiber can also help you maintain a healthy weight.

Fiber foods are mostly tasty. You do not necessarily have to gulp your food to consume more fiber.

This article will take you through the benefits of fiber and a list of 20 high-fiber foods you should eat.

Dietary Fiber

Dietary fiber is the non-digestible component in your plant-based food. It is also known as bulk or roughage. Unlike carbohydrates, fats, and proteins, fiber remains intact throughout the digestive tract and is excreted from the body as such.

17 High-fiber foods you must include in your diet

Dietary Fiber Classification

1. Soluble Fiber:

It can dissolve in water. The important role of soluble fiber includes:

•    Blood glucose regulation

•    Delayed gastric emptying

•    Reduce serum cholesterol

All these roles are secondary to colonic fermentation (metabolization of fiber by bacteria in the gut) and increased viscosity of gut content due to soluble dietary fiber.

Rich sources of soluble fiber include apples, beans, carrots, oranges, peas, barley, oats, and psyllium.

2. Insoluble Fiber: 

It is insoluble in water. It supports the growth of probiotics species of bacteria, shortens the bowel transit time and improves the bulk of fecal matter, thereby inducting laxative effect.

Individuals who struggle with irregular stools and constipation are more likely to benefit from insoluble fiber.

Rich sources of inorganic fiber include nuts, wheat bran, green beans, potatoes, and cauliflower.

Most plant-based foods contain both types of fiber, but in varying amounts. Eat a wide variety of fiber-foods to gain more significant benefits.

Benefits of a High-fiber Diet

In the past two decades, research has discovered many benefits of eating fiber diet. From preventing chronic conditions to improving gut functions, fiber has important roles to play.

1. High fiber intake can reduce weight.

As discussed earlier, fiber soaks up water and aids in slow digestion and absorption of food. The resulting fullness keeps calorie intake low.

Low appetite and a reduced intake of calories are great for your weight loss goals. Soluble fiber is more likely to produce this effect.

2. Dietary fiber reduces sugar spikes in the blood.

Unlike refined carbohydrates, high-fiber foods – especially those with soluble fiber – have a low glycemic index, which means fiber food does not cause sugar spikes in blood after meals. This property of fiber is especially useful for individuals with diabetes.

3. High fiber intake reduces constipation.

Fiber is famous for its laxative properties. It increases the bulk and water content of stool. A bulky and soft stool is more comfortable to pass through the rectum. Fiber also reduces the risk of hemorrhoids and diverticular disease.

A research study conducted on individuals with chronic constipation showed that switching to low-fiber diet improved constipation in study subjects, whereas those who remained on high-fiber diet achieved no greater benefit. However, other studies showed that fiber improves bowel movements.

It seems like not all fiber is created equal. The fiber that increases the water content of your stool is generally more helpful in relieving or preventing constipation as compared to insoluble fiber. A good example of fiber with laxative effect is psyllium and sorbitol.

4. Fiber foods lower bad cholesterol levels.

Soluble fiber may help lower your cholesterol levels by reducing low-density lipoproteins (LDL) levels. There isn’t much evidence to support this statement, especially in terms of long-term effects. However, a few controlled studies show that consuming 2-10 grams of soluble fiber daily is associated with up to 2 mg of LDL reduction.

Observational studies also show that people who take high-fiber diets have a better lipid profile as compared to those who eat refined carbs and fatty foods.

5. Fiber is good for gut flora.

The fact may surprise you, but we have 10 times more bacteria than cells in our body. Don’t be scared. These are good bacteria, or at least they cause no harm unless an opportunity arises, like low immunity.

Although these bacteria are found in every region of the body, the large intestine is particularly a high-bacterial region.

The gut bacteria – also known as gut flora – consist of about 100 trillion cells from 500 different species of bacteria. While we provide food and shelter to these microorganisms, they return the favor by doing a few things humans are incapable of.

The question is: what does gut flora have to do with dietary fiber?

Well, the indigestible fiber is actually digestible for good bacteria found in our large intestine. Since fats, carbs, and proteins are usually absorbed into the bloodstream before reaching the large intestine, dietary fiber – which reaches large intestine in its intact form – feeds the gut flora. It promotes good bacteria in the gut and creates a win-win situation for both humans and the bacterial colonies residing in our intestines.

6. Dietary fiber reduces the risk of type 2 diabetes.

There have been many observational studies on the association between type 2 diabetes risk and fiber intake. In a meta-analysis constituting studies from 1974 to 2013, it was seen that 19,033 cases out of 488,293 participants reduced their risk of type 2 diabetes through fiber intake.

Moreover, a few cohort studies have also shown a positive association between fiber intake and reduced risk for type 2 diabetes.

Daily Fiber Requirements

The Institute of Medicine recommends 38 and 25 grams of fiber for daily intake in men and women aged 50 or younger, respectively.

For older men and women, it is 30 and 21 grams, respectively.
