FOR THE FIRST TIME, GUT BACTERIA HAS BEEN SPOTTED EATING CHEMICALS IN THE BRAIN

Standaard

Scientists are finally starting to understand the gut and brain connection, and this understanding can lead to huge breakthroughs in regard to various mental disorders, and how what’s going on in the gut could actually be a culprit for many of these illnesses. Many are surprised to learn that an estimated 90% of the serotonin produced by the body actually comes from the gut! This may lead us to believe that proper nutrition, gut microbiome, and digestion might be a key component to a healthy mind.

 Recently, bacteria have been discovered in the gut that depends solely on one of the chemicals in our brains for survival. These bacteria consume a molecule known as GABA; this molecule is crucial for calming the brain. This shows directly how gut bacteria can affect our mood.

Philip Strandawitz and his colleagues from Northeastern University in Boston have recently discovered that a species of recently discovered gut bacteria, called KLE1738 could only be grown if it was provided with GABA molecules. While announcing his findings at the annual meeting of the American Society of Microbiology in Boston last month, Strandawitz said, “Nothing made is grown, except GABA.”

GABA acts by inhibiting signals from nerve cells, which calms down the activity of the brain. This is why it’s so surprising that a bacteria in the gut needs it in order to grow and reproduce. Interestingly enough, low levels of GABA are directly linked to depression and other mood disorders. The findings of this study just provide further evidence that the bacteria in our gut are directly affecting the function of our brains.

What Does This Mean For Treatment Of Depression?

An experiment performed in 2011 showed how a type of gut bacteria called Lactobacillus rhamnosus can actually alter the GABA activity in the brains of mice, as well as directly influencing how the mice are responding from stress. Researchers involved in this study found that this effect disappeared when they surgically removed the vagus nerve, linking the gut to the brain, in the mice. This suggests that it plays a role in the influence that gut bacteria have on the brain.

Now, Strandawitz is looking for other gut bacteria that consume, or alternatively produce GABA. This way he can test their effects on the brains and behavior of animals. This research may eventually lead to alternative treatments for various mood disorders including depression and anxiety.

Is It Really As Simple As Diet?

Perhaps. We can’t really say for sure, but having a healthy gut can relate to having a healthy mind. There are more and more instances being documented from people who have completely changed their diets, and the impact it has had on their mood, symptoms of depression and, believe it or not, on autism as well.

There are many different contributing factors leading to an imbalance of gut flora, which in turn can lead to various mental and physical issues. Overuse of antibiotics without taking probiotics can cause this, not being breastfed as a baby could lead to gut issues down the road, also, being born from a C-section can also cause issues later on, as the beneficial bacteria that would normally be passed to the baby during birth is bypassed. These factors and more can lead to many different ailments and allergies.

After all our guts go through, it is no surprise that many of us are struggling with so many health disorders and allergies, but having this awareness – that so much is dependent on an optimal functioning gut and digestive system – is the first step towards taking back our health!

I highly suggest the book, Medical Medium by Anthony William, where these topics are explored on a much deeper level.

Have you changed your life by changing your diet and bringing balance to your gut flora? Let us know your story!

Much Love

Gut bacteria found to trigger gene that protects against type 1 diabetes

Standaard

Researchers have discovered that a powerful guardian gene known to protect against a variety of autoimmune diseases, including type 1 diabetes, is triggered by the bacteria in our gut. This finding offers a clue to the complex interaction between our genes, immune system and gut microbiota.

Scientists at the Harvard Medical School set out to investigate what factors influence the activity of a powerful gene complex known as the human leukocyte antigen (HLA). It has been known for some time that specific variants of HLA genes in humans and major histocompatibility complexes (MHC) in mice can protect against diseases such as type 1 diabetes, but how that influence is exerted has been a mystery.

The team focused on gut bacteria as being a potential catalyst for modulating the genes’ activity. In a series of experiments, non-obese diabetic (NOD) mice engineered to carry a guardian gene were treated with gut bacteria killing antibiotics at various times in their development.

The mice treated with antibiotics during the first six weeks of life were found to subsequently develop symptoms of early stage type 1 diabetes despite holding the protective guardian gene. On the other hand, when treated with antibiotics at between six and 10 weeks of age, the mice still displayed signs of genetic diabetic resistance.

These results imply that early-life formation of gut microbiota has a significant effect on gene modulation influencing immune system behavior. The experiment also delivered antibiotics to mother mice in the 10 days before giving birth and discovered this also disrupted their offspring’s genetic protections. This particularly highlights the influence of a mother’s microbiota on her offspring.

Exactly how the bacteria in the gut affects gene activity is still unknown, but the researchers suggest that this offers clear evidence of how disrupting the early development of an individual’s gut microbiome can usurp any genetic predisposition and alter proper immune function.

“Our findings need to be borne out in further experiments,” says co-lead of the study Diane Mathis. “However, our results powerfully illustrate the notion that early antibiotic exposure can modulate disease risk and that avoiding or at least minimizing antibiotic treatment in infants and pregnant women during critical periods of development may be a good idea.”

The last experiment the team conducted involved fecal transplants from mice with the guardian gene to mice without that genetic protection. The mice receiving the fecal transplant displayed a reduction in pancreatic cell inflammation, the general marker signaling the onset of type 1 diabetes. This solidifies the role gut bacteria plays in regulating our immune system and suggests future treatments for autoimmune diseases could be targeted at the gut microbiome.

The new research was published in the journal Proceedings of the National Academy of Sciences.

Your Gut Can Help Fight Depression and High Blood Pressure

Standaard

By Dr. Mercola

Trillions of bacteria live in your gut, influencing your body’s homeostasis daily. Far from being restricted to the confines of your intestinal tract, your gut microbiota is intricately tied to other body systems via a number of complex pathways, including the gut-brain axis and a recently revealed gut-brain-bone marrow axis, the latter of which may influence your blood pressure, mood and more.

It’s becoming increasingly clear that your brain, your immune system and your gut microbes are intricately linked, so it’s not a stretch to add bone marrow to the list of connections. Immune cells stem from bone marrow, and bone marrow inflammation, which may result from high blood pressure, is known to be caused by a signal from the brain. In a study published in the journal Frontiers in Physiology, researchers further revealed that immune cells in bone marrow play an important role in signaling between the brain and gut.1,2

Gut-Brain-Bone Marrow Connection Revealed

In an animal study, researchers replaced natural bone marrow in mice with bone marrow cells from genetically engineered (GE) mice. The marrow had been modified to be deficient in adrenergic receptor beta, making it less responsive to messages from the brain.

“In this way,” researchers wrote in The Conversation, “we could investigate how the host brain-immune communication will modify gut microbiota. Indeed, by studying this new mouse model, we determined that our nervous system — directed by our brain — can modify the composition of gut microbiota by communicating directly with the bone marrow immune cells. The brain, therefore, can change our gut microbiota indirectly by talking to the bone.”3

In short, when bone marrow was less able to communicate with the brain, a “muted inflammatory response” was observed in the gut, which in turn led to a more diverse (i.e., healthier) microbiome. The study shed light on one of the complex ways your gut health may be implicated in that of your heart and brain, with researchers noting:4

“In the context of cardiovascular disease, this muted inflammatory response appears to be beneficial, as it leads to beneficial lowering of blood pressure in our experimental mice.

Most interestingly, a link between gut microbiota and our mental health has recently become clearer. In particular, some have suggested that gut microbiota influence the stress and anxiety pathways in the brain in a way that can alter mood and behavior both positively and negatively, giving a whole new meaning to the term ‘gut feeling.'”

Imbalanced Gut Microbes Play a Role in High Blood Pressure

Imbalanced gut microbes, known as gut dysbiosis, have been previously linked to heart disease and high blood pressure, but a recent animal study shed further light on the unique connection.5 Researchers gave rats antibiotics for 10 days to wipe out their natural microbiota, then transplanted hypertensive microbiota into rats with normal blood pressure. Rats with high blood pressure, in turn, were transplanted with normal microbiota.6

The results were surprising in that the rats treated with hypertensive microbiota developed high blood pressure, while the transplantation of normal microbiota led to only a slight reduction in blood pressure among the hypertensive rats. “We conclude that gut dysbiosis can directly affect SBP [systolic blood pressure],” the researchers wrote, adding that manipulating gut microbiota, such as via the use of probiotics or eating fermented foods, may be an “innovative treatment for hypertension.”7

However, it’s not the first time such a link has been revealed. A systematic review and meta-analysis of nine randomized, controlled studies found significant benefits among people with high blood pressure who consumed probiotics in products like yogurt and milk.8 On average, compared to a placebo, the probiotic consumption lowered systolic blood pressure (the top number) by 3.56 mm Hg and diastolic blood pressure (the bottom number) by 2.38 mm Hg.

It appeared that at least 100 billion colony-forming units of probiotics a day were necessary to trigger such improvements, and the benefit was only seen in those who consumed probiotics for eight weeks or more. In 2015, meanwhile, certain gut microbes, namely firmicutes and bacteroidetes, were associated with increased blood pressure in rats.

“Products of the fermentation of nutrients by gut microbiota can influence blood pressure by regulating expenditure of energy, intestinal metabolism of catecholamines, and gastrointestinal and renal ion transport, and thus, salt sensitivity,” according to research published in the journal Current Opinion in Nephrology and Hypertension.9

Probiotics Found to Benefit Gut Diseases, Mental Health

The addition of beneficial microbes has been found to benefit people struggling with serious gut diseases, including necrotizing enterocolitis (NEC), which often occurs in premature infants and can be fatal. An Australian study revealed that probiotic supplementation significantly reduced NEC risk and mortality in preterm neonates, lowering the incidence of NEC in premature babies by at least 30 percent.10

Probiotics have also been found to benefit irritable bowel syndrome (IBS), of which disturbances in the gut microbiota are often seen.11Compared to placebo, probiotic therapy was found to reduce pain and symptom severity among people with IBS,12 and probiotics are also known to prevent antibiotic-associated diarrhea in children.13

On the mental front, a small study involving adults diagnosed with IBS and depression found the probiotic Bifidobacterium longum provided depression relief. At six weeks, 64 percent of the treatment group had reduced depression scores compared to 32 percent of the control group that received a placebo.14

Those receiving the probiotic also reported fewer symptoms of IBS and improved overall quality of life. At the end of 10 weeks, approximately twice as many in the treatment group were still reporting lower levels of depression.

Interestingly, functional MRI scans revealed a link between reductions in depression score and actual changes in brain activity, specifically in areas involved in mood regulation, such as the amygdala. As noted by Dr. Roger McIntyre, professor of psychiatry and pharmacology at the University of Toronto, who was not involved in the study:15

“We know that one part of the brain, the amygdala, tends to be red-hot in people with depression, and it seemed to cool down with this intervention. It provides more scientific believability that something in the brain, at a very biological level, seems to be affected by this probiotic.”

Are Personalized Probiotics the Answer?

As for which strains of probiotic are best, the answer may be harder to come by. Emma Allen-Vercoe, a microbiologist at the University of Guelph in Ontario, told Scientific American, “Bacterial strains are so genetically different from one another, and everybody has a different gut microbiota … There will probably never be a one-size-fits-all probiotic.”16

Studies suggest, for instance, that some people may benefit more from probiotics than others if they’re “low” in a certain variety that is then added to their diet. As Scientific American reported:17

“In other words, their gut ecosystems had a vacancy that the probiotic filled. That is exactly the kind of insight that clinicians need to create and recommend more effective probiotics. If a doctor knows that an individual with severe diarrhea has an undersized population of a particular beneficial microbe, for example, then prescribing the missing strain should increase the chance of a successful treatment.”

Other research has looked into the benefits of certain strains of bacteria, such as Bifidobacteria, which tend to be abundant in babies’ intestines but typically make up less than 10 percent of the gut microbiome bacteria in adults.18 Low levels of Bifidobacteria, in turn, are linked to chronic diseases like celiac disease, diabetes, allergic asthma and even obesity, while supplementing with them has been found to benefit IBS, inflammatory bowel disease, chronic fatigue syndrome, psoriasis, depression and more.19

Another type of bacteria, lactobacillus, has been shown to reduce anxiety in animal studies,20 while taking a probiotic with eight different bacterial strains reduced aggressive and ruminative thoughts in a study of adult volunteers.21,22

The Lectin Connection and How Leaky Gut Can Destroy Your Health

It’s important to be aware that gut dysbiosis, also known as leaky gut, is not only a major gut disrupter linked to digestive disorders, but may also contribute to other chronic diseases like Alzheimer’s and possibly cancer. If your gut is leaky, your blood-brain barrier is also leaky, which means toxins can go right into your brain, affecting your cognitive and mental health.

Further, leaky gut can be triggered by a number of factors, including imbalanced gut microbiota that result from dietary factors, such as the consumption of sugar as well as lectins. This latter component is very important. Lectins are plant proteins, sometimes called sticky proteins or glycan-binding proteins, because they seek out and bind to certain sugar molecules on the surface of cells. There are many types of lectins, and the main difference between them is the type of sugar each prefers and binds to.

Some — including wheat germ agglutinin (WGA), found in wheat and other grass-family seeds — bind to specific receptor sites on your intestinal mucosal cells and interfere with the absorption of nutrients across your intestinal wall.

As such, they act as “antinutrients,” and can have a detrimental effect on your gut microbiome by shifting the balance of your bacterial flora — a common precursor to leaky gut. Dr. Steven Gundry, author of “The Plant Paradox: The Hidden Dangers in ‘Healthy’ Foods That Cause Disease and Weight Gain,” makes a strong case for a lectin-free diet, stating:

“Our microbiome is, I think, our early warning system, because about 99 percent of all the genes that make up [the human body] are actually nonhuman, they’re bacterial, viral and fungal … [from which] we’ve uploaded most of the information about interacting with our environment … because the microbiome is capable of almost instantaneous changing and information processing that we actually don’t have the ability to do.

We’re beginning to realize … that the microbiome is not only how we interact with plant materials … like lectins, but probably more importantly, our microbiome teaches our immune system whether a particular plant compound is a friend or foe [based on] how long we’ve known that plant compound. There are lectins in everything.

But the longer we’ve interacted with lectins and the longer our microbiome has interacted with them, the more our microbiome kind of tells our immune system, ‘Hey, guys, it’s cool. We’ve known these guys for 40 million years. Chill out. They’re a pain, but we can handle them.’

From an evolutionary perspective, if you look at modern foods — say the grains and the beans, which we started interacting with 10,000 years ago, which is a blink of time — our microbiome [regards them as] foreign substances … [T]here’s no lectin speed dating in evolution.”

Lectins are strongly associated with autoimmune disorders of all kinds, primarily by triggering leaky gut. They’re found in many of our most cherished foods, such as:

Potatoes Eggplants Tomatoes Peppers Goji berries Lima beans
Cashews Peanuts Sunflower seeds Chia seeds Pumpkin seeds Kidney beans
Squash Corn Quinoa Soybeans Wheat Lentils

In addition, according to Gundry, glyphosate, which is not only sprayed on GE crops via Roundup but also is used to desiccate wheat in the U.S., is also highly problematic, decimating your microbiome and increasing leaky gut. It’s yet another reason to eat organic as much as possible.

To learn more, I highly recommend picking up a copy of “The Plant Paradox,” especially if you’ve already cleaned up your diet and still struggle with excess weight and/or health problems. Certainly, anyone with an autoimmune disorder would also be wise to take a closer look at lectins.

How to Support a Healthy Microbiota

Supporting your microbiome isn’t very complicated, but you do need to take proactive steps to encourage its health while avoiding factors known to cause harm. In addition to the lectin information above, consider the following recommendations to optimize your microbiome:

Do Avoid
Eat plenty of fermented foods. Healthy choices include lassi, fermented grass fed kefir, natto (fermented soy) and fermented vegetables. Antibiotics, unless absolutely necessary, and when you do, make sure to reseed your gut with fermented foods and/or a high-quality probiotic supplement.
Take a probiotic supplement. Although I’m not a major proponent of taking many supplements (as I believe the majority of your nutrients need to come from food), probiotics are an exception if you don’t eat fermented foods on a regular basis Conventionally-raised meats and other animal products, as CAFO animals are routinely fed low-dose antibiotics plus GE grains loaded with glyphosate, which is widely known to kill many bacteria.
Boost your soluble and insoluble fiber intake, focusing on vegetables, nuts and seeds, including sprouted seeds. Chlorinated and/or fluoridated water. Especially in your bathing such as showers, which are worse than drinking it.
Get your hands dirty in the garden. Exposure to bacteria and viruses can help to strengthen your immune system and provide long-lasting immunity against disease.

Getting your hands dirty in the garden can help reacquaint your immune system with beneficial microorganisms on the plants and in the soil.

Processed foods. Excessive sugars, along with otherwise “dead” nutrients, feed pathogenic bacteria.

Food emulsifiers such as polysorbate 80, lecithin, carrageenan, polyglycerols and xanthan gum also appear to have an adverse effect on your gut flora.

Unless 100 percent organic, they may also contain GMOs that tend to be heavily contaminated with pesticides such as glyphosate. Artificial sweeteners have also been found to alter gut bacteria in adverse ways.23

Open your windows. For the vast majority of human history, the outside was always part of the inside, and at no moment during our day were we ever really separated from nature.

Today, we spend 90 percent of our lives indoors. And, although keeping the outside out does have its advantages it has also changed the microbiome of your home.

Research shows that opening a window and increasing natural airflow can improve the diversity and health of the microbes in your home, which in turn benefit you.24

Agricultural chemicals, glyphosate (Roundup) in particular is a known antibiotic and will actively kill many of your beneficial gut microbes if you eat foods contaminated with it.
Wash your dishes by hand instead of in the dishwasher. Research has shown that washing your dishes by hand leaves more bacteria on the dishes than dishwashers do, and eating off these less-than-sterile dishes may actually decrease your risk of allergies by stimulating your immune system. Antibacterial soap, as it too kills off both good and bad bacteria and contributes to the development of antibiotic resistance.

Probiotic cure for peanut allergies shows long-term success

Standaard

Sometimes the slow, measured pace of medical research is frustrating. On average it takes about 12 years for a new drug to move from discovery to general practice, but each step towards approval is important as it validates whether or not these new medicines actually work and are safe. A new four-year follow-up study on the efficacy of a probiotic-based peanut allergy cure has revealed the majority of the original participants are still displaying tolerance to peanuts, paving the way for the final phase of trials to bring the treatment to the public.

In 2013, a team at the Murdoch Children’s Research Institute in Melbourne, Australia, completed a study involving over 60 children suffering from peanut allergies. Over 18 months the children either received a placebo or a combination of the probiotic Lactobacillus rhamnosus with a peanut protein. At the end of the study 82 percent of the children receiving the probiotic treatment could safely eat peanuts.

“It appears that we have been able to modify the allergic response to peanut such that the immune system produces protective responses rather than a harmful response to the peanut protein,” said pioneer of the therapy Professor Mimi Tang, four years ago after the original study was published.

A big question that remained was whether this degree of peanut tolerance would hold over the long term. Now four years later the long-term data is in – and it’s extraordinarily positive. Eighty percent of those subjects that were tolerant of peanut by the end of the original study were still regularly eating peanuts years later with no problems.

“These children had been eating peanut freely in their diet without having to follow any particular program of peanut intake in the years after treatment was completed,” says Professor Tang of the recent follow-up work.

The research also suggests that a tolerance-based treatment for food allergies could be a realistic and effective target for addressing other food allergies.

The next step for the researchers is to move into Phase III clinical trials, which are often considered the most expensive and time-consuming part of the development process as they involve large patient groups across multiple locations. In the US the FDA can sometime approve treatments to market while they are still undergoing Phase III trials.

The team at the Murdoch Children’s Research Institute has already jointly set up a company called Prota Therapeutics with a goal of moving this treatment through to public use as quickly as possible. No specific timeframe has been outlined, but the treatment should be available in the near future and could dramatically change the lives of many people suffering from this dangerous allergy.

The new follow-up study was published in the journal The Lancet Child & Adolescent Health.

De darmflora en hoe je bent wat je eet

Standaard

Voor een goede gezondheid hebben we bacteriën nodig. Pas sinds een paar decennia wordt telkens weer duidelijk hoe de invloed van de darmflora een stuk verder reikt dan de darmen. Een juiste samenstelling van het darm microbioom helpt lichaam én geest. In dit artikel: de laatste probiotica-onderzoeken zodat je weer op de hoogte bent.

Probiotica en onze gezondheid

(meest recente onderzoeken)

Activatie killercellen

Probiotica kunnen de natuurlijke killercellen activeren (natural killercells, NK-cellen). Dit is belangrijk voor de gezondheid, omdat NK-cellen (witte bloedcellen) zieke cellen doden. Het gaat dan met name om de lactobacilli- en bifidobacteriastammen (L. acidopholus en B. breve). 1

Gunstige veranderingen in darmflora

Kefiranofaciens is te vinden in kefir. Deze bacteriesoort koloniseert (bij muizen) succesvol de darmflora en de darmwand, Toen de streng gedurende een week intensief werd toegediend, bleek het voor een toename van boterzuur-producerende bacteriën te hebben gezorgd. Ook de hoeveelheid Lactobacilli was toegenomen. 2

Preventief effect bij infectieuze ziekten kinderen

Lactobacillus paracasei voorkomt infectieuze ziekten bij jonge kinderen. Dit bleek toen kinderen de bacteriesoort nuttigden via koemelk. 3

Gunstig bij inflammatoire darmziekte

Onder inflammatoire darmziekten vallen colitis ulcerosa en Crohn’s. De samenstelling van de darmbacteriën is bij deze ziekten ernstig verstoord. De resultaten met probiotica kunnen wisselend zijn. VSL#3 bleek wel voordeel te bieden. Het voordeel van dit was gelijk aan dat van 5-ASA (mesalazine).4 VSL#3 is een product met de hoogst beschikbare concentratie bacteriën.

Bij diarree

Diarree bij oudere mensen, die veroorzaakt wordt door Clostridium difficile kan aangepakt worden door Lactobacillus casei, Lactobacillus bulgaricus en Streptococcus thermophiles. Deze zitten in Actimel. L. bulgaricus wordt gevonden in yoghurt. De resultaten bij ouderen met diarree bleken wel wat wisselend.

Bifidobacteria en de algehele gezondheid

Bifidobacteria hebben een positieve werking op de gezondheid in het algemeen. 5 Hetzelfde geldt voor Lactobacilli. 6 In gefermenteerde yoghurt of kefir zijn verschillende van deze soorten te vinden.

Voor neuroprotectie

Via de brein-darm as communiceert het gastro-intestinale systeem met het centrale zenuwstelsel. Om deze reden wordt gesuggereerd dat controle over de darmflora de symptomen van neurodegeneratieve ziekten kunnen verlichten. 7

Bij gastro-intestinale stoornissen

Suppletie van probiotica kan gastro-intestinale stoornissen en auto immuunziekten voorkomen. Vitamine D draagt samen met de vitamine D receptor bij aan het beschermende effect van probiotica. Zie tabel voor de verschillende probioticastammen en hun werking. 8

Koreaanse gefermenteerde voeding

In Koreaanse gefermenteerde voeding, zoals gefermenteerde groenten (kimchi), zit L. plantarum. Van L. plantarum is bekend dat het de immuunrespons verbetert, de groei van pathogenen remt en dat het toxines bestrijdt. 9 Kimchi is ook verkrijgbaar in poedervorm.

Als je je darmflora gezond wilt hebben en houden, kun je kunstmatige zoetstoffen beter vermijden. Acesulfaam-K verandert het gewicht, de stofwisseling en tevens de samenstelling van de darmflora bij muizen, meldt PLOS One. 10 Dit effect is ook bekend bij mensen en geldt ook voor andere kunstmatige zoetstoffen.

Zoals je ziet heeft elke bacteriestam weer een eigen specifieke werking. Dit kon je ook lezen in de vorige artikelen over probiotica. Toch hoef je je niet te beperken tot een stam. Met meer stammen oogst je meer voordelen. Dus varieer lekker met probioticarijke voeding. Je doet je immuunsysteem een plezier (75% van het immuunsysteem zit in de darmen). Diversiteit is belangrijk, want het ontbreken hiervan staat in verband met auto immuunziekten en ontstekingsaandoeningen. Probiotica helpen de stofwisseling en ondersteunen de opnamen van vitaminen en mineralen. Behalve deze rijke bronnen van probiotica, eet je ook veel vezels en yoghurt om de goede bacteriën de kans te geven te floreren. Volgens experts kun je de samenstelling van de micro-organismen in de darmen vrij snel veranderen; de een noemt een paar dagen, volgens de ander kan het binnen een maand. Wees consequent en geef niet op!

Small study shows probiotics can beat back depression

Standaard

In March of this year, researchers showed that a probiotic found in yogurt was able to reverse symptoms of anxiety and depression in mice. Now, in a small study involving 44 adults, investigators at McMaster University in Canada have shown a different probiotic can have the same effect in humans.

Increasingly, scientists are exploring the link between our guts and our brains, and finding that the two are very much linked. Earlier this year, researchers found that they could alter the gut microbiota by beaming people’s’ brains with magnetism, and last year, a study indicated that certain molecules in the gut can inhibit inflammation it the brain.

The McMaster research focussed on individuals with irritable bowel syndrome (IBS) which, the university says, is the most common gastrointestinal disorder in the world. The study split 44 adults into two groups. One group took the probiotic Bifidobacterium longum every day for ten weeks, while the other group took a placebo.

At six weeks, in the group taking the probiotic, 14 out of 22 participants (64 percent) had a lower depression score than the group taking the placebo. What’s more, the researchers saw changes in brain areas associated with depression in the probiotic group when they observed them using functional MRI (fMRI) scans.

“The fMRI study showed decreased activity in the amygdala and other fronto–limbic regions of the brain, which are known to be involved in the control of mood, in the patients taking with probiotics compared to those taking placebo,” Premysl Bercik told us. Bercik is an associate professor of medicine at McMaster and senior author on the study.

Of course, one theory is that the symptoms of depression went away in the study subjects taking the probiotic because their IBS symptoms also improved. So we asked Bercik about that, and he said that the effects of the probiotic treatment on mood lasted longer than the effects on the IBS symptoms – longer than the treatment was carried out, in fact.

“You are right,” he told us, “the patients on probiotics also reported improvement in their IBS symptoms (adequate relief of symptoms) at the end of the probiotic treatment, but not four weeks later when the beneficial effect on depression was still present. So one can argue that the primary effect of this probiotic is on depression. Also, the amygdala is one of the important centers in processing abdominal pain so if the probiotic altered the function of this brain region, it could also improve the gut symptoms of IBS (the pain is the hallmark symptom of IBS).”

The study, which was carried out in conjunction with scientists from food giant Nestlé, has been published in the journal Gastroenterology.
