April 19, 2021

DALLAS — In his newest book, Dr. Colbert’s Healthy Gut Zone” (DrColbertBooks), Dr. Don Colbert explains to his readers that prebiotics are incredibly beneficial to the gut’s microbiome and their entire GI tract. “While probiotics are living organisms, prebiotics are more like insoluble fiber—undigestible and existing solely to serve your gut bacteria.”

Prebiotic fiber is a non-digestible part of foods that travels through the small intestine undigested and is fermented when it reaches the large colon. “The fermenting action feeds the good bacteria in your colon,” writes Dr. Colbert. “Though prebiotics can be in supplement form, the most common way to get prebiotics is through the foods we eat.”

According to Dr. Colbert, there are many prebiotics available. A few on his list include:

  • Apples
  • Asparagus
  • Bananas
  • Flaxseed
  • Garlic
  • Onions
  • Wheat bran

In Dr. Colbert’s Healthy Gut Zone,” Dr. Colbert writes, “To have a healthy gut, you must eventually feed your gut what it needs once the bloating and gas have been contained. That means feeding the good bacteria with prebiotics. The good bacteria then can multiply and benefit your whole body.”

Dr. Colbert also addresses additional benefits of prebiotics: Prebiotics provide energy, help with weight loss, increase mineral (i.e., magnesium, calcium) absorption, reverse common adverse effects of stomach acid blockers, strengthen the probiotics already in the gut and suppress hunger.

“With my patients, I tell them to eventually aim for 12 grams of prebiotics per day once gas and bloating have resolved,” states Dr. Colbert. “How much is that? If you are getting the fiber and probiotics your body needs, then adding about a handful of prebiotic foods to your daily diet should be sufficient. Use as many naturally prebiotic-rich vegetables in your salads or cooked meals as you want. The more it becomes a habit, the better.”

Dr. Colbert’s newest book is available through Amazon, Barnes and Noble, BAM, ChristianBook, Indiebound and Walmart.
