My kids and I love smoothies and, whenever we want to promote gut health and regular bowel movements, we simply add in a scoop of Peak BioBoost to tap into the healing power of prebiotic benefits (even when we’re on the go). Note, I said “prebiotics,” not probiotics… Prebiotics are plant fibers that help with the growth of healthy intestinal bacteria (aka “probiotics”). They reach the terminal portion of the gastrointestinal tract and are fermented and consumed by the natural flora of the intestines. In other words, they are literally food for your healthy gut bacteria. They help promote the growth of healthy bacteria and keep the abnormal and harmful population in check. This then has dozens of health benefits throughout your entire body. (1) Here, we’ll review all the benefits of prebiotics and why they are essential for you so you can make an informed decision about your health.

Why Do We Need Probiotics?

Our body hosts all kinds of organisms in our intestines. Human gut microflora regulates critical activities in our body including healthy bowel habits, adequate immune response, and protection from the various cancer-causing mechanisms, among literally dozens of others. The population of probiotics is mainly regulated by the food you eat, but many other factors can also contribute. (2) Any imbalance in the bacterial population in the gut is directly responsible for significant metabolic abnormalities and illnesses. This is why it is crucial to regulate gut flora for a person’s well-being. A balanced population can be achieved by adequate intake of prebiotics in your diet.

5 Health Benefits of Prebiotics

Prebiotics are the main modulators of bacterial growth in the gut. Most people assume that their benefits remain limited to just regulation of bowel movements and gut flora. This can’t be further from the truth. As an emerging non-pharmacological means to regulate gut flora and promote well-being, prebiotic use is constantly being studied for its beneficial effects on the body. Studies have shown the therapeutic efficacy of prebiotics against constipation, obesity, colorectal cancer, and inflammatory bowel disease along with their role in the absorption of various essential minerals and vitamins.

Let’s dig into a few more specific benefits you’ll enjoy by regularly consuming prebiotics…

Effect On Immune System

One of the principal effects of prebiotics is the stimulation of the immune system. When digested, prebiotic fibers get fermented by bacteria in the colon to produce short-chain fatty acids (SFAC). These SFACs are small enough to cross the gut wall and enter the circulation to exert local and systemic effects. (4) According to studies, they have a protective effect against infectious diseases of the gut and antibiotics associated with diarrhea. Gut flora is responsible for the activation of innate and adaptive immunity. These microorganisms exert their effect directly by activating the mucosal immune cells which fight off infection or indirectly by increasing the population of useful lactobacillus. Not only that, they stimulate the antibody response toward viral vaccines making the body less susceptible to infections and providing increased resistance against the infection.

Effect on Gut Health

Prebiotics stimulate the growth of gut flora and help improve certain aspects of gut health. Gut microflora is the main component of gut health. They regulate the immune function, improve the mucosal barriers and maintain the pH to nourish the bowel wall. Stimulating the growth of these microorganisms may benefit those with intestinal health problems like constipation, inflammatory bowel disease or malabsorption. (5) Probiotics help in improving the symptoms of Inflammatory bowel disease by producing SCFAs and by decreasing the number of sulfate-reducing bacteria. This combination has an anti-inflammatory effect on the gut wall thus relieving the symptoms of IBS. A 2020 review stated that treatment with prebiotics showed significant improvement in patients having constipation dominant IBS. (6) Not only that, but it also plays a viable role in regulating bowel movement and relieving constipation. SCFAs production by these bacteria acts directly on the intestinal wall to enhance intestinal motility thus helping in improving the frequency and consistency of stool. (7)

Effect on Cardiovascular Health

There is a growing trend of cardiovascular diseases in the US population due to changing diet choices and lifestyle alterations. According to statistics, on average someone dies of CVD every 36 seconds in the US and someone has a stroke every 40 seconds. (8) Prebiotics can help with that. Research has found consistent evidence that prebiotic use lowers the risk of cardiovascular accidents by maintaining optimum cardiac health. (9) Cardiovascular health is mainly compromised by high cholesterol levels and increased blood pressure. Prebiotics helps maintain the cholesterol level in the body and increase the clearance of LDL from the body thus keeping a balanced lipid profile. (10) SCFAs produced by prebiotics are capable of crossing the mucosal barrier and exerting systemic effects. (11) They are metabolized in the liver causing vasodilation and lowering the blood pressure. The combined effect of lower LDL and blood pressure results in improved cardiac health and a lower risk of cardiac accidents.

Prevention of Obesity

Obesity is spreading like an epidemic in the US. Higher BMI is associated with various diseases like high blood pressure, diabetes, cardiovascular accidents, and organ failure. Obesity is associated with an unbalanced metabolism of fat in our body in response to alterations in the bacterial flora of the intestines. Probiotics promote satiety and regulate the absorption of glucose and fat. They increase the concentration of beneficial bacteria. They are also responsible for reducing intestinal inflammation and improving gut barrier integrity. It leads to balanced metabolism of fats and glucose, thus promoting weight loss. (12) Studies have also shown that there is an association between probiotics and secretion of satiety-promoting substances and delayed gastric emptying. (13) This means probiotics enhance the feeling of fullness to decrease food intake and maintain overall energy balance. These combined effects of probiotics can help in reducing weight and in preventing the epidemic of obesity.

Improve Absorption Of Several Minerals

Probiotics help in the absorption of essential minerals like calcium and magnesium and possibly iron. (14) They are necessary for maintaining bone integrity and structure. Probiotics help in maintaining the pH of the gut lumen to increase the solubility and absorption of these minerals. (13)

Why Peak BioBoost Creates Gut Healthy Food

Probiotics are essential for maintaining body health. There are dozens of other documented health benefits of prebiotics we haven’t even touched on today. To do so would require hundreds of pages of text. Unfortunately, we’re not getting enough of them in our diet. Prebiotics are generally found in the raw form of foods that most people don’t eat regularly, such as…

  • Raw chicory root
  • Raw Jerusalem artichoke
  • Raw dandelion greens
  • Raw garlic
  • Raw or cooked onions (to a lesser extent)
  • Raw jicama
  • Raw asparagus
  • Raw green bananas

That’s why we recommend adding prebiotics to your daily routine through supplement form. Luckily scientists have discovered how to isolate the health-boosting prebiotics from these foods so you can enjoy the benefits in a much more convenient way. Our favorite is a product called Peak BioBoost. It contains several types of prebiotic fibers in a flavorless, easily mixable powder you can add to your coffee or tea to enjoy regular bowel movements along with the dozens of health benefits we’ve described today. Whether you take a supplement or not, it’s important getting prebiotic fiber into your daily diet. Many people call them the “new multivitamin” and we wholeheartedly agree!

NLF “Group Buy”! Give your body the support it needs to maximize gut health by adding prebiotic benefits to your healthy lifestyle. Peak BioBoost will help you optimize your digestive system in powerful ways.
