If you’re health conscious in the least, you’ve likely heard that a healthy gut is important if you want to naturally encourage your healthiest days.
Many trends and diets in natural health come and go but thanks to science, we now know about the critical importance of the human gut—and supporting gut health is all about nurturing your good bacteria and having plenty of it to fill all the little niches in your system.
So, while your gut bacteria are hard at work keeping you healthy and thriving, the question you might be asking yourself (and one others have been pondering, too) is this:
What keeps your gut bacteria healthy and thriving?
The answer that’s creating waves in the natural health community is prebiotic fiber.
How Prebiotics Help Maintain Overall Health
Prebiotics are carbohydrates that pass through your digestive tract undigested, and then make their way into your colon where your good bacteria (aka probiotics) use them for fuel.
Nearly all prebiotics are fibers found in plant-based foods, and most fruits and vegetables contain at least a small amount of the indigestible fibers that your gut bugs just love to eat.
And, in order to grow and multiply (and keep you healthy), your beneficial bacteria need to consume a steady diet of prebiotics...provided, of course, by you.
Indeed, because prebiotics enable probiotics to fulfill their human life-supporting duties, the benefits of a diet rich in prebiotics to your health are extensive. That’s why we expect to see prebiotic foods and recipes just about everywhere in the natural health space.
Consider these incredible benefits of consuming plenty of prebiotic fiber:
• Glowing digestive health. Research indicates that by encouraging the growth of the good bacteria in your gut (which also crowds out the bad guys), prebiotics can help you avoid common digestive issues that can arise from a lack of healthy bacteria, like temporary irregularity, bloating, gas, and undesirable yeast growth.1
• Balanced moods and stress management. We know that our gut and brain are connected and that friendly flora can help to modulate our emotions by helping to regulate and produce important neurotransmitters. Now, studies suggest that consistent prebiotic fiber consumption can lower levels of cortisol—the stress hormone—and support balanced emotions.2 Who doesn’t want that?
• Strong, healthy bones. By supporting your body’s ability to absorb important minerals like calcium, foods rich in prebiotic fiber can help maintain bone density and health.3 Here’s how it works: prebiotics encourage growth of certain types of friendly flora that produce short-chain fatty acids, which decrease the pH in the colon. Lower pH supports mineral solubility and absorption!
• Healthy weight management. Prebiotics can both encourage levels of hormones that tell you when you’re full and discourage levels of hormones that tell you when you’re hungry. This makes it easier to manage your weight.4
• Robust immunity. Studies show that prebiotics can help your gut flora support your immune function. With 80% of the immune system living in your gut and depending on a healthy balance of bacteria to support it, prebiotics nourish your probiotics so they can help keep your immune system strong.5
• A strong gut barrier. Your gut barrier is a vital component of your immune system that—when intact—keeps invaders from entering your bloodstream. The good news is that your beneficial bacteria can ferment prebiotics into short-chain fatty acids like butyrate that nourish your intestinal cells and keep your gut barrier strong, which helps keep you healthy!6
And that’s just the tip of the iceberg when it comes to the benefits of prebiotics.
To paint an even clearer picture of why prebiotics are the next big thing in natural wellness, consider this: prebiotics are so important to your gut and overall health, that they are abundantly present in breast milk, as human milk oligosaccharides (HMOs) that nourish baby’s crucial first microbes.
So, if prebiotics are a crucial element of nature’s brilliant design to support the growth and development of a baby’s microbiome, surely we are meant to continue consuming them to support our own microbiome through all of our years!
Types of Prebiotics: Spotlight on Resistant Starch
Many prebiotics are indigestible fibers and sugars—such as inulin, oligofructose, fructooligosaccharides (FOS), and galacto-oligosaccharides (GOS)—that are naturally-occurring in a variety of fruits and vegetables.
But, another type of prebiotic is making its way into the gut health line-up for its amazing benefits—resistant starch.
True, you may have spent the last several years staying far away from starchy foods full of empty calories, but researchers are discovering that certain components of these former maligned ingredients are actually prebiotics that feed your good bacteria.
You see, some starchy foods—like potatoes, green bananas, and legumes—have components that are resistant to digestion (hence the name, resistant starch). This part of the starch gets fermented by your gut bacteria, often into butyrate and other short-chain fatty acids that nourish your intestinal lining and lower the pH of your large intestine to discourage inhospitable microbes.
So, what are the effects of resistant starch? In addition to all the well-known prebiotic benefits mentioned above, resistant starch seems to have a couple of its own tricks up its sleeve, such as:
1. Maintaining blood sugar levels already in a normal range. Research shows that resistant starch increases insulin sensitivity, which means you need less insulin to keep your blood sugar levels in a healthy range.7
2. Efficient fat burning. In one study, replacing just 5.4% of carbohydrate intake with resistant starch led to a 20-30% increase in fat burning after meals.8
It’s clear that prebiotics are like fertilizer for your microbial garden, and are imperative for a thriving microbiome.
Prebiotic Powder to Support a Healthy, Happy Gut
Fortunately, prebiotics are readily available in a variety of foods, like bananas, asparagus, leeks, garlic, onions, and Jerusalem artichokes. Unfortunately, it’s very difficult to consume enough of these foods to keep your microbiome healthy.
Why is this? First and foremost, archaeological research explains that our ancestral diet tens of thousands of years ago contained more than 100 grams of fiber every day—that’s a lot of fuel for mighty microbes!9 For example, Aborigines in Australia ate 300 different fruit species, 150 varieties of tubers and roots, and a countless number of vegetables, nuts, and seeds, ultimately consuming around 130 grams of fiber per day.
These cultures had healthier and more diverse microbiomes as a result of their diet, but the problem is that we just don’t have access to the variety of plants our foraging ancestors gathered. And when you consider that, in the United States, the average adult only eats about 15 grams of fiber/day, you can see that we are far behind ideal numbers when it comes to fiber and prebiotic consumption.
Secondly, so many things in our modern lifestyle deplete our beneficial bacteria and if we don’t have enough of the good guys (about 85% in a balanced microbiome) to stay in charge, the bad guys can take over—and a low prebiotic fiber intake just can’t make a dent in a microbiome overrun with undesirable bacteria.
Here’s how you can incorporate prebiotics, probiotics, and a healthy gut into your personal wellness maintenance plan:
1.Take a high-quality daily probiotic (like PRO-15), and steer clear of anything that can deplete your microbiome.
2. Choose a whole food diet rich in plant-based and prebiotic-rich foods, such as apples, bananas, whole oats, asparagus, and tomatoes (or countless others).
3. Add a daily scoop of our 100% organic and food-based Prebiotic Powder to transform any meal into a variable feast for both you and your good gut bacteria.
With Jerusalem artichoke (inulin), green banana (resistant starch), and acacia fiber (soluble fiber), our organic, food-based prebiotic formula gives you seven grams of fiber per tablespoon of powder that you can easily mix into smoothies and soft foods for a prebiotic punch that will have your microbes jumping for joy.
Research shows us that optimal gut health is about much more than just eating well. To truly enjoy vibrant and lasting wellness and vitality, we must nurture our gut bacteria with a variety of prebiotics that give them the fuel they need to support our health from the inside out. It’s truly a trend that’s here to stay.
