Prebiotics feed the “good” bacteria that live in your gut.
Prebiotic compounds are made up of non-digestible plant fibers found naturally in many foods.
Providence physicians say prebiotics to your diet can provide numerous health benefits, including reduced heart disease and cancer risk.
Who’s your favorite dynamic duo? Do you prefer a classic pairing like Batman and Robin, Fred and Ginger, or even Thelma and Louise? Or are Bert and Ernie or Wile E. Coyote and Road Runner more your speed? Whatever your answer, chances are good “prebiotics and probiotics” were not at the top of the list. But maybe they should be.
Prebiotics and probiotics are vital components of gut health. Although they sound similar, both play very different roles in keeping your gastrointestinal system happy.
- Probiotics are “good” bacteria that live in your gut.
- Prebiotics are a type of fiber that feeds the healthy bacteria.
We’ve put together a two-part series that looks at prebiotics and probiotics, outlines their health benefits and offers tips on adding them to your diet. This month we’ll focus on prebiotics.
What are prebiotics?
Prebiotics consist of non-digestible plant fibers that promote the growth of beneficial bacteria. Prebiotic compounds remain undigested as they pass through the upper portion of your gastrointestinal tract. They then travel through your small intestine and arrive at your colon, where they serve as food for your healthy bacteria.
Although prebiotics are available as dietary supplements, you can include them in your daily intake without adding any special pills, prescriptions or potions. Be sure to talk to your doctor before making any dietary changes.
Prebiotics and diet
Eating the right foods can help your beneficial gut bacteria flourish. The best source of prebiotics is whole foods that naturally contain prebiotics. Prebiotics are found in a variety of raw fruits and vegetables or whole grains. Sources include:
- Acacia gum or gum arabic
- Chicory root
- Dandelion greens
- Jerusalem artichokes
- Raw garlic
- Under-ripe bananas
- Whole wheat
Some products have been fortified with added prebiotics, including baby formula, bread, cookies or yogurt. The label doesn't typically include the word "prebiotic" when listing ingredients. Instead, look for the following words to determine if your food contains the nutrition you’re looking for:
- Chicory fiber
Health benefits of prebiotics
Research shows prebiotics can have a significant impact on your health. Studies from the National Institutes of Health show increasing your prebiotic intake can provide many health benefits, including:
- Reduced risk of heart disease
- Reduced risk of colorectal cancer
- Less inflammation throughout your body
- Improved immunity responses
- Improved neural activity for better brain function and memory
- Decreased likelihood and severity of allergic skin conditions such as dermatitis
- Better calcium absorption
- Balanced blood sugar levels
- Prevention of irritable bowel disease
Prebiotics release metabolic byproducts, some of which are thought to influence brain function, according to a study at the University of Colorado Boulder. Researchers found a prebiotic-rich diet lowered stress levels, improved both brain function and sleep quality. And the Academy of Nutrition and Dietetics says prebiotics “may improve gastrointestinal health as well as potentially enhance calcium absorption.”
Health risks of using prebiotics
If you’re adding prebiotics to your diet, start with a small amount and gradually increase your consumption a little at a time. Too much at once can lead to unpleasant side effects, including:
- Abdominal pain
A healthy gut with well-balanced bacteria is an essential aspect of maintaining an active, healthy lifestyle. Talk to your doctor about ways you can add prebiotics to your daily eating plan.
