Gut bacteria play an essential role in maintaining overall physical and mental wellbeing; communicating with your brain through an intricate network called the gut-brain axis. Thankfully, supporting good gut bacteria with diet can be easy!

Choose whole food, fiber-rich fermented foods (kefir, yogurt and sauerkraut are rich sources of prebiotics and polyphenols) and get moving regularly to optimize stress reduction and mood improvements.

Boosts Your Immune System

As is widely acknowledged, your gut microbiome plays a critical role in digestion as well as other bodily processes. But its influence extends well beyond your digestive tract – gut bacteria also regulate immunity, metabolism and brain functioning via what’s known as “gut-brain axis,” with recent research suggesting probiotics could improve quality of life through this key link.

The gut microbiome contains trillions of bacteria that help our immune systems and protect us against illness. Unfortunately, its balance can shift due to certain diseases or lifestyle choices (diet, stress, heavy drinking, smoking and lack of exercise). Probiotics provide an easy solution for restoring that equilibrium; they are naturally found in some foods such as yoghurt or fermented vegetables such as sauerkraut as well as through supplements taken as medicine.

Probiotic bacteria ingested via food enter the digestive tract where they begin to colonise your healthy gut microbes, competing with pathogenic microbes for adhesion sites and nutrients while encouraging beneficial microbe growth. They produce complex carbohydrates such as exopolysaccharides (EPS), which serve as food sources for beneficial bacteria as well as improving gut barrier function and immunomodulatory properties.

Probiotics have also been found to activate immune signalling pathways that enhance both innate and adaptive immunity, including stimulating production of antimicrobial cytokines. Furthermore, probiotics may promote maturation of regulatory T cells while simultaneously encouraging B cells to produce antibodies against pathogenic microbes.

Probiotics have also been shown to ease inflammation in the digestive tract and bowels by helping treat ulcerative colitis, Crohn’s disease, chronic irritable bowel syndrome symptoms (such as bloating, abdominal pain and diarrhea) caused by H. pylori infections such as stomach ulcers or antibiotic-associated diarrhoea.

Be mindful that probiotic effects will differ for every individual; to get optimal results from taking probiotics, find your ideal type and dose by speaking to your healthcare provider first. Also, before adding new supplements to your diet, consult with them.

Supports Mental Health

Our digestive tract is home to trillions of microbes known as our gut microbiota, or “good” bacteria. These “good” bacteria aid digestion, boost your immunity system, help control blood sugar levels and have even been known to influence mood and mental wellbeing. Unfortunately, their balance may become disturbed due to factors like disease, poor diet and lifestyle behaviors, heavy drinking, stress or ageing – leaving us vulnerable.

Probiotics, live bacteria and yeast found naturally in some foods like yogurt and fermented vegetables like pickles and sauerkraut, can help restore your gut to health, but supplements are also an option.

Studies show that maintaining a healthy gut microbiota can aid with various conditions, from anxiety and depression to heart disease and cancer.

Probiotics have the ability to impact our mood in several ways. One is through increasing levels of monoamines like serotonin and dopamine in our brains by feeding our gut lining with food that increases its permeability, thus enabling these chemicals to enter. [21]

Research also suggests that probiotics can help alleviate inflammation in the GI tract, which could potentially contribute to depressive symptoms. They do this by decreasing lipopolysaccharides – which has been linked with depressive disorders – released during periods of stress [22].

Studies demonstrate the ability of specific probiotic strains to assist with anxiety and depression, with Lactobacillus casei and Bifidobacterium longum being proven to decrease depression and anxiety in randomized clinical trials conducted by Akkasheh et al. and Kato-Kataoka et al.

Probiotics have also been demonstrated to boost mood. Examples include Bifidobacterium infantis and Bifidobacterium longum as well as Saccharomyces boulardii.

Guts UK advocates eating a range of prebiotics – food that feeds your gut microbes – such as artichokes, bananas, asparagus, garlic, onions, cruciferous vegetables legumes and wholegrain cereals as sources. You may also find prebiotics available as dietary supplements such as oats barley or seaweed.

Reduces Stress

Your “butterflies in your stomach” before an important event are more than merely nerves; they’re a result of two-way communication between your gut and brain via something known as the gut-brain axis. Whatever goes on in your gut is transmitted directly into your brain, while vice versa. Furthermore, research suggests probiotics may be effective at improving mental health by means of this linkage.

Your gut microbes play an essential role in supporting your immunity, metabolism and even brain functioning. They help regulate blood pressure levels and manage cholesterol levels – so it should come as no surprise when gastrointestinal issues have an adverse impact on mental wellbeing.

Recent studies on probiotics as stress relievers have produced promising results, including one published in Psychosomatic Medicine 2021 which found a combination of probiotic bacteria improved depression symptoms among clinical patients by altering intestinal microbiota composition and controlling cortisol levels.

This was the first study to demonstrate how probiotics could effectively lower stress in humans by altering neurotransmitters, hormones, and bioactive substances like corticotropin-releasing factor. Another research review and meta-analysis concluded that probiotic supplements may significantly decrease subjective stress level among healthy volunteers as well as alleviate subthreshold anxiety/depression levels associated with stress. A wide variety of probiotic strains can be used to relieve stress; more research needs to be conducted into which are most beneficial in relieving specific individuals of stress relief.

While it is possible to consume probiotics via supplement pills, many prefer adding fermented foods into their meals as another way of getting probiotics into their systems. You could try substituting kombucha for soda or juice; adding sauerkraut or kimchi to salads; or trying your luck at making homemade kefir or yogurt from scratch – taking these steps toward your long-term healthy goals may take just minutes a day – Nutrition & Integrative Physiology graduate teaching assistant Maria Manuela Herrera shares her favorite recipes & tips for creating probiotic-rich swaps.

Improves Digestion

By including probiotics in your diet, you are adding beneficial bacteria that help support a healthy gut environment. Your digestive tract contains trillions of bacteria which keep things running smoothly but sometimes their balance becomes unbalanced due to diseases, medications or lifestyle behaviors such as eating processed foods, smoking cigarettes or failing to get enough exercise. Probiotics provide beneficial microbes which support this natural balance within the body.

The gut is more than just a digestive tract; it also forms an intimate partnership with your brain through something known as the gut-brain axis. Your brain receives information about your digestive system through this connection; probiotics may improve this communication further by strengthening digestive health while simultaneously supporting brain wellness.

Probiotics don’t always produce immediate effects for healthy people taking them, especially if their digestive symptoms are mild or moderate. Most probiotics need time to make their way through your stomach and intestines before beginning work on you – however if taken regularly over time you should eventually notice positive changes to your digestion symptoms.

As an example, when taking probiotics that contain lactobacillus species like L. reuteri, these microbes will help your gut digest dairy more effectively – possibly relieving symptoms of lactose intolerance or constipation. They also enhance bowel function and can reduce constipation. Enterococcus faecium strains support gut-brain axis function and may lower infection risk. Choosing scientifically researched probiotics with plenty of active ingredients ensure they’ll thrive within your digestive tract.

Probiotics are taken orally and travel down your throat before entering your stomach, where they’re then released into both small intestines (intestines) and large intestines (bowel). Finally, probiotics may take root elsewhere on your body such as your nose or genital region.

ISAPP (International Scientific Association for Probiotics and Prebiotics) recently convened an expert panel to investigate the benefits of probiotics once more. Experts from diverse fields, including gastroenterology, paediatrics, family medicine, nutrition, gut microbiome research, microbial genetics and food science were represented on this expert group.
