Gut health and probiotics -

Did you know that all multicellular organisms, including every animal and plant, are covered in a vast array of microorganisms? Microorganisms, also known as microbes, are extremely small microscopic , living organisms, such as bacteria, viruses, yeast, parasites, and more.

They live on our skin, in our body fluids, and throughout our digestive tract in large quantities and varieties. The moment we are born, we encounter countless microorganisms. The number of single-celled organisms on and within you is greater than the number of cells that make up your own body.

This collection of microorganisms, which is unique to each individual, is their microbiota. The collection of the genetic information from all these microorganisms in a specific environment is referred to as the microbiome. Different parts of the body, for example the skin or the intestinal tract, have their own microbiomes and microbiota.

The gut microbiome is exceptionally diverse, with estimates of trillion microorganisms, from , different species! Despite these vast numbers and varied species there is a fine balance. We have co-evolved with these microorganisms — we give them a place to live and food to eat and they help support our overall health.

They produce certain vitamins and short chain fatty acids, interfere with the growth of harmful bacteria, modify the immune system, and improve our health in ways researchers are only beginning to study.

Microbiome: the aggregate of microorganisms, their genetic information, and the conditions of the environment they are in such as the intestinal tract. Microbiota: the microorganisms that inhabit a specific environment such as the intestinal tract. Microorganism: a very small microscopic organism, such as a bacterium, virus, or yeast.

Antimicrobial Antibiotic : a medicine that either inhibits growth of or destroys microorganisms. Probiotic: live microorganism usually bacteria administered with the purpose of improving health.

When we think about the bacteria that colonize, or live in, our intestinal tract, we typically sort them into two categories: beneficial strains of bacteria non-pathogenic , including those in the genera Bifidobacterium and Lactobacillus, and potential disease-causing strains of bacteria pathogenic , including enteropathogenic EPEC and enterohemorrhagic EHEC Escherichia coli, Shigella, and Clostridioides difficile.

Beneficial bacteria keep pathogens in check and offer many health benefits. Disease-causing bacteria release proteins and toxic by-products that can cause inflammation and harmful symptoms such as diarrhea. Some, such as Helicobacter pylori , can be both beneficial in certain quantities and harmful in other quantities.

The balance between beneficial and harmful bacteria is important for maintaining health. The diversity, or different types of microorganisms, of our gut microbiome is critical — greater diversity allows our gut to be resilient and bounce back from any disturbances to the balance.

Several factors can upset this balance, including diet, stress , hygiene, and medications, particularly antibiotics. Dysbiosis occurs when there are shifts in the balance of the microbiota. The beneficial bacteria that populate the digestive tract work in many possible ways, depending on the type of bacteria and other factors, including:.

There are many ways to treat and manage dysbiosis. In cases of bacterial infection, antibiotic treatment might eradicate the offending bacteria. When the problem is ongoing, probiotics and prebiotics can help return balance to the microbiome. In this section, we will explain how we can use these tools to affect the gut.

Canadian laws specify that a probiotic product must contain live microorganisms that research shows to be beneficial, in adequate amounts to confer a health benefit. You will most often find probiotics in the form of supplements, but some foods also contain probiotics not to be confused with fermented foods; see below.

Typically, an approved probiotic will contain a limited variety of beneficial bacteria, sometimes a few strains and sometimes just one. However, the strain s will be a type of bacteria or other microorganism that research studies show to be effective for treating a specific ailment.

The live bacteria populate the gut and help improve the balance in the microbiome, as well as exert specific effects. Bacteria from the Bifidobacterium and Lactobacillus genera can improve health in many ways, but different strains can exert different effects.

For example, research shows that Bifidobacterium infantis Align® can improve abdominal pain, bloating, and gas in those who have irritable bowel syndrome IBS. This probiotic is an effective option for individuals with these specific symptoms, but it might not be helpful for someone with a different set of symptoms or benefit someone with no digestive troubles.

In recent years, there have been many claims made about gut health — especially on social media platforms like TikTok. If you take even just a few minutes to scroll through the GutTok hashtag on the app, you'll see dozens and dozens of videos discussing the health issues a bad gut can cause like increased acne and inflammation, and even more of them touting the benefits of paying special attention to, and healing, your gut like a strong immune system and clear skin.

Probiotics are "beneficial bacteria that keep your gut microbiome healthy," according to Daryl Gioffre , a certified nutritionist and gut health expert. Studies show that probiotics produce substances that activate the immune system and "prevent pathogens from taking hold and creating major disease," according to Harvard Health Publishing.

Probiotics may also lower the number of colds you have in a year, the health hub notes. While probiotics can be found in several foods, Gioffre believes that "supplementation of probiotics has become necessary" because we aren't getting as many probiotics through our diets as our ancestors have in the past.

Here are the most important facts you should know about probiotics and how to get more of them in your system. Harvard Health Publishing also recommends some dairy products like yogurt, especially Greek yogurt, and kefir. When it comes to probiotic supplements, Gioffre suggests taking different types of probiotics and ideally changing the type every three months.

There are two main types of probiotic supplements that Gioffre recommends: spore-based and terrain-based. And the reason is that the digestive system is a harsh terrain.

When you take this probiotic supplement, it's got to go down through the acid in your stomach," he says. Once a spore-based probiotic reaches your gut, its shell opens up and attaches to the gut wall to strengthen the microbiome.

Some probiotic products have been reported to contain microorganisms other than those listed on the label. In some instances, these contaminants may pose serious health risks.

NCCIH-Funded Research NCCIH sponsors a variety of research projects related to probiotics or the microbiome. In addition to the previously mentioned studies on diet-microbiome interactions in the digestive tract, recent topics include: The mechanisms by which probiotics may help to reduce postmenopausal bone loss Engineering probiotics to synthesize natural substances for microbiome-brain research The mechanisms by which certain probiotics may relieve chronic pelvic pain The effects of a specific Bifidobacterium strain on changes in short-chain fatty acid production in the gut that may play a role in antibiotic-associated diarrhea.

This is especially important if you have health problems. Anyone with a serious underlying health condition should be monitored closely while taking probiotics.

: Gut health and probiotics

Probiotics: What You Need To Know	However, there is some research that can help you find a product that meets your needs. Before taking a probiotic, speak with your healthcare team and make sure that there is evidence that the specific strain you wish to take may be beneficial for you. Also, a trusted group of experts has created an evidence-based guide on probiotic products available in Canada that can support you in your care. The Alliance for Education on Probiotics AEProbio is an international collaboration of doctors, researchers, and scientists working together to promote the clinical use of probiotics for better health outcomes. Each year, they conduct an unbiased review of the available scientific evidence on probiotics to update the Clinical Guide to Probiotic Products Available in Canada. Probiotics are products that contain specific strains of bacteria in adequate quantities for which there is evidence showing its efficacy at treating a specific condition. While the most obvious way to increase the number of beneficial bacteria in your gut is to take a probiotic, you can also feed the good bacteria already in your gut so that they reproduce and populate a higher proportion of your microbiota. There are certain carbohydrates in our food that we cannot digest, which we call fibre. There are many types of fibre in our food, and helpful bacteria love to chow down on some of them. These special fibres are prebiotics. The most well known and extensively studied prebiotic is inulin, a type of fructo-oligosaccharides FOS found in plants such as chicory, whole grains, onion, garlic, asparagus, banana, tomatoes, and Jerusalem artichokes, among many others. Chicory is sold commercially as Benefibre® inulin , although there are other types as well. Galacto-oligosaccharides GOS are plant sugars linked in chains found in breast milk and fermented dairy products, beans, and certain root vegetables. When you eat these foods, the prebiotics stay intact through the stomach and small intestine, then bacteria in the large intestine break the fibres down fermentation and use them as fuel. This allows the bacteria to reproduce, leading to larger colonies of good bacteria. Make sure to increase your prebiotic intake gradually, since sudden changes in the quantity of fibrous foods you eat can cause bloating, abdominal pain, and other digestive symptoms. Many people mistakenly claim that fermented foods, such as yogurt and sauerkraut, contain probiotics. As we discussed earlier, probiotics are products that must contain a certain amount and type of live bacteria, based on scientific evidence for certain conditions. Fermented foods contain the microorganisms that initiated the fermentation. However, the strains of bacteria that these products contain can be variable, and they may or may not still be active by the time they reach your intestinal tract. For these reasons, eating fermented foods is a less reliable way of increasing the populations of beneficial bacteria in the gut than taking probiotic supplements. If it works with your dietary routine, adding in foods such as yogurt, kefir, sauerkraut, kimchi, and kombucha can be a nice accompaniment to any probiotics you might take to treat digestive diseases and disorders. There are just as many, if not more, microorganisms living in your digestive tract and on your skin as there are cells in your body! When bacteria eat, they produce waste, and while it might sound gross, these waste products can help us. For example, when bifidobacteria eat fibre, they produce short-chain fatty acids, which our bodies use to improve immune function and strengthen the intestinal barrier. Some researchers have been looking at these end-point products and considering the possibilities of delivering them directly to the gut. This might offer a way to bypass the complication of getting living organisms into the gut unharmed, and instead provide the benefits directly. In addition, this could be a way for individuals who are immunocompromised to obtain the benefits of probiotics. The human microbiome has incredible genomic diversity with almost one hundred fold more genes than in human cells. You are probably very familiar with antibiotics. While antibiotics kill the bacteria that are causing you to be sick, they also kill helpful bacteria. For instance, yeast infections and Clostridioides difficile C. difficile , formerly known as Clostridium difficile , infection often occur after taking antibiotics. In some cases, C. difficile infection recurs, and may continue to recur, because the microbiome is imbalanced to the point that it is unable to restore itself. Occasionally, taking probiotics after a course of antibiotics might prevent further damage to the microbiome by repopulating it in a beneficial manner. However, in many cases it is unnecessary and might make it take longer for the microbiome to recover. Not all antibiotics are created the same, there are types available now and in development that target specific bacteria rather than the entire microbiome. Remember that probiotics are regulated like food, not drugs. Probiotic manufacturers are not obligated to prove any health benefits of their products. Probably not. No studies have ever shown that probiotics reduce abdominal pain. In the office, I encourage people to think about a healthy fiber-rich diet instead of probiotics. Dietary fiber is a prebiotic—it changes which bacteria are present in the gut. Fiber is inexpensive and natural, and by changing your dietary fiber intake you are changing your gut bacteria.

This story has played out before, most notably with vitamin supplements, which decades of research have revealed to be completely unnecessary for most adults and, in some cases, dangerous, correlating with higher rates of lung, breast and prostate cancers. But that has not stopped marketers from pushing another nutritional craze. According to a National Institutes of Health survey, the number of adults in the U. taking probiotics or their cousins, prebiotics typically nondigestible fibers that favor the development of gut bacteria , more than quadrupled between and , from , people to nearly four million. The popular frenzy surrounding probiotics is fueled in large part by surging scientific and public interest in the human microbiome: the overlapping ecosystems of bacteria and other microorganisms found throughout the body. The human gastrointestinal system contains about 39 trillion bacteria, according to the latest estimate, most of which reside in the large intestine. In the past 15 years researchers have established that many of these commensal microbes are essential for health. Collectively, they crowd out harmful microbial invaders, break down fibrous foods into more digestible components and produce vitamins such as K and B The idea that consuming probiotics can boost the ability of already well-functioning native bacteria to promote general health is dubious for a couple of reasons. Manufacturers of probiotics often select specific bacterial strains for their products because they know how to grow them in large numbers, not because they are adapted to the human gut or known to improve health. The particular strains of Bifidobacterium or Lactobacillus that are typically found in many yogurts and pills may not be the same kind that can survive the highly acidic environment of the human stomach and from there colonize the gut. Even if some of the bacteria in a probiotic managed to survive and propagate in the intestine, there would likely be far too few of them to dramatically alter the overall composition of one's internal ecosystem. Whereas the human gut contains tens of trillions of bacteria, there are only between million and a few hundred billion bacteria in a typical serving of yogurt or a microbe-filled pill. Last year a team of scientists at the University of Copenhagen published a review of seven randomized, placebo-controlled trials the most scientifically rigorous types of studies researchers know how to conduct investigating whether probiotic supplements—including biscuits, milk-based drinks and capsules—change the diversity of bacteria in fecal samples. Only one study—of 34 healthy volunteers—found a statistically significant change, and there was no indication that it provided a clinical benefit. Despite a growing sense that probiotics do not offer anything of substance to individuals who are already healthy, researchers have documented some benefits for people with certain conditions. While many small studies have been conducted, there has been no standardized way to study probiotics and their effects, making it difficult to compare the results of different studies. Probiotics are not regulated by the Food and Drug Administration, which means the companies that make probiotics do not need to prove the product contains the ingredients listed on the bottle. Talk to your health care provider before starting a probiotic. People with very weak immune systems, such as those undergoing chemotherapy, should not take probiotics due to risk of infection. Your provider or a nutritionist can help identify a probiotic containing the bacteria strain based on the condition you wish to address. Eat a varied diet of protein, grains, fruits and vegetables. Research has shown that a diet containing a variety of different foods is beneficial to our gut microbiome. Engage in regular physical activity. Studies have shown that a healthy diet and physical activity have separate, positive benefits on our overall wellness. Lisa Hayes, M. Skip to main content. Posted By.
