20 Ultimate High-Fiber Foods

High Fiber Foods Title

Are you getting enough fiber?

Fiber, we know we need it, but even with all the fiber-added foods out there, most people are still deficient.

The modern western diet has left Americans with a serious nutrient deficiency, fiber. It is estimated that less than 5 percent of Americans get the recommended amount of dietary fiber each day. High fiber foods help to guard against cancer, heart disease, diverticulosis, kidney stones, PMS, obesity, and help to support a healthy digestive tract. Fiber is much more than just a regulator.

Benefits of High-Fiber Foods

*The following fiber content is based on Harvard: Fiber Content of Foods in Common Portions, except where otherwise noted.

Many processed foods including cereals and breads, have added fiber. These sources of fiber used in for this supplementation are not the healthiest. In fact, just as with popular fiber supplements, many ingredients may be harmful to your health. So, as it is with all nutrients, it is much better to eat fresh foods, rich in the nutrients you need.

There are many lists out there of high fiber foods; this list is focused on perhaps lesser-known fiber stars. All of the foods listed below are not just high in fiber, but essential nutrients that help our bodies thrive.

Cook on high for 3.5 – 4.5 hours or on low for 8 – 10 hours, until they reach desired doneness. This process creates a creamy bean, without being mushy.

What is Fiber?

After the discussion of the ultimate high fiber foods, let’s take a look at just what fiber is. First, it is important to note that fiber only occurs in fruits, vegetables, and grains. It is part of the cellular wall of these foods. Diets high in fiber may reduce the risk of obesity, heart disease, and diabetes. (3)

Along with fiber and adequate fluid intakes, fiber is responsible for quickly moving foods through the digestive tract, helping it function optimally. Fiber works by drawing fluids from the body to add bulk to the stool. When increasing dietary fiber in your diet it is essential to start slowly, and increase gradually.

Recommended Daily Fiber:

Women 25 grams

Men 35-40 grams

The vast majority of Americans get less than half of the daily recommended fiber. Without fiber, our digestive tract suffers, we develop high cholesterol that may lead to heart disease, and inflammation may increase in the body.

High fiber diets help to lower the risk of some cancers, diverticulosis, heart disease, irritable bowel syndrome, kidney stones, and obesity. Some studies show that women with PMS or those that are menopausal can experience some relief from symptoms with high-fiber diets.

For individuals with digestive tract conditions, dietary fiber may help to relieve symptoms. High fiber helps to shift the balance of bacteria, increasing healthy bacteria, while decreasing the unhealthy bacteria that can be the root of some digestive problems.

The Difference Between Soluble Fiber & Insoluble Fiber

Insoluble fiber’s job is to provide bulk in the intestines, while helping to balance the pH levels in the intestines. It promotes regular bowel movements, and helps to prevent constipation. Insoluble fiber doesn’t dissolve in water, and doesn’t ferment with bacteria in the colon. It is believed to help prevent diverticulosis and hemorrhoids, while sweeping out carcinogens and toxins from the system. Nuts, seeds, potatoes, fruit with skin, and green vegetables are excellent sources, as mentioned above.

The job of soluble fiber is much the same, however it creates a gel in the system binding with fatty acids. Studies show that it prolongs stomach emptying to allow for better absorption of nutrients. Soluble fiber helps to lower cholesterol and helps to regulate blood sugar levels for individuals with diabetes. It is present in beans, legumes, oats, barley, berries, and some vegetables. It does ferment in the stomach, which can lead to bloating and gas. Increase these foods gradually, and drink plenty of water.

Both soluble fiber and insoluble fiber has recently been show to be important in helping to control and manage hypertension. (4)

What Fiber Does for Your Body

Fiber helps to regulate bowel functions, reduce cholesterol and triglycerides, and strengthens the colon walls. In addition, it helps in weight loss, management of blood sugar levels, and may prevent insulin resistance and associated diseases. Dietary fiber intake may prevent insulin resistance and disease. (5In addition, a recent study found that women who eat a high fiber diet (38-77 grams per day) had a greater than 20% reduction in risk for developing ovarian cancer. (6)

Benefits of Getting Fiber From Foods, Instead of Supplements

The supermarket and drug store shelves are packed with fiber supplements, so the natural question is why not just take those supplements instead. I hope in this article we have sold you on the benefits of eating high fiber foods mentioned above, because of their health benefits.

As another consideration, fiber supplements typically only contain a small fraction of necessary fiber. And, the sources of the fiber are often suspect. Beware of any supplements that contain methylcellulose (synthetic cellulose), calcium polycarbophil, or wheat dextrin as they provide no food value and nutrients, and are synthetic.

In addition, according to a study from the University of Maryland Medical Center, people taking some medications including for diabetes, cholesterol-lowering drugs, seizure medications, and some antidepressants are advised not to take fiber supplements as it may interfere with the absorption of these medications and some minerals.

The 20 ultimate high fiber foods on this list are the best way to get the fiber you need; incorporate fiber slowly, and drink plenty of water and non-caffeinated beverages to help the fiber do its job.
