Fiber Supplements

Fiber is very important to get in our daily diet and unfortunately, most Americans fall short.  Turning to fiber supplements is one of the easiest ways to get it in.   Simple additions of either a pill or powder allows us to get in our recommended daily amount. 

Fiber Factoid:

  • Fiber plays an essential role in your digestive, heart, and skin health, and may improve blood sugar control, weight management, and more
  • Whole grains are not the best source of fiber, as they contain anti-nutrients and glutinous, “binding” proteins; vegetables, nuts, and seeds are the most healthful sources of fiber
  • If your gut health is compromised, fiber may feed pathogenic bacteria; healing your gut with probiotic-rich fermented vegetables is recommended before eating a high-fiber diet
  • Most people need upwards of 50 grams of fiber per 1,000 calories consumed; most Americans get nowhere near this amount

Benefits of Supplementing with Fiber

Why is something completely insoluble to the body so important to ingest?  The FDA recommends that Americans eat between 20-30 grams of fiber a day; however, most adults don’t get even close. Vegetables, fruits, nuts and seeds are among the healthiest forms. Fiber refers to the indigestible portion of these plant foods. Unfortunately, the American diet is so processed that the beneficial healthy fibers are refined out. Fiber is classified as soluble (like cucumbers, beans and nuts) and insoluble (found in dark leafy greens, celery and carrots). Both are important to get in our diet. Soluble fiber benefits by dissolving into a gel which helps slow down digestion.  Insoluble fiber does not dissolve and adds bulk. The benefit being food is moved through more quickly to help in elimination; taking out bad things with it.

9 Health Benefits of Fiber

There’s no shortage of research showing how fiber may boost your health. Some of its top potential benefits include:

Blood sugar control: Soluble fiber may help to slow your body’s breakdown of carbohydrates and the absorption of sugar, helping with blood sugar control.

Heart health: An inverse association has been found between fiber intake and heart attack, and research shows that those eating a high-fiber diet have a 40 percent lower risk of heart disease.

Stroke: Researchers have found that for every seven-grams more fiber you consume on a daily basis, your stroke risk is decreased by 7 %.

Weight loss and management: Fiber supplements have been shown to enhance weight loss among obese people, likely because fiber increases feelings of fullness.

Skin health: Fiber, particularly psyllium husk, may help move yeast and fungus out of your body, preventing them from being excreted through your skin where they could trigger acne or rashes.

Diverticulitis: Dietary fiber (especially insoluble) may reduce your risk of diverticulitis – an inflammation of polyps in your intestine – by 40 percent.

Hemorrhoids: A high-fiber diet may lower your risk of hemorrhoids.

Irritable bowel syndrome (IBS): Fiber may provide some relief from IBS.

Gallstones and kidney stones: A high-fiber diet may reduce the risk of gallstones and kidney stones, likely because of its ability to help regulate blood sugar.

Healthiest Sources of Fiber

If your diet could use more fiber, resist the urge to fortify it with whole grains. Instead, focus on eating more vegetables, nuts, and seeds. The following whole foods, for example, contain high levels of soluble and insoluble fiber.

Chia seeds, Berries, Vegetables such as broccoli and Brussels sprouts, Root vegetables and tubers, including onions and sweet potatoes, Almonds, Psyllium seed husk, flax, chia seeds, Green beans, Cauliflower, Beans, and Green Peas
