(Mercola)—Fermented foods stand out as a potent intervention when it comes to influencing your mental health by impacting a symbiotic relationship inside the body, which is called the gut-brain axis. Here, the influx of probiotics influences your mental health, and your current mood subsequently influences your microbiome. While the symbiosis looks simple on paper, it’s a complex communication network, underscoring the importance of eating fermented foods regularly.
Understanding the Link Between Fermented Foods and Mental Health
Fermented foods are rich in beneficial probiotics and metabolites, which influence your gut microbiota composition and diversity. These foods have been well-studied, and researchers eventually discovered that the human body has a communication pathway between your gut and brain — the gut-brain axis.1
When you eat fermented foods, the probiotics and other bioactive compounds begin to influence the communication between your gut and brain. In particular, a fascinating aspects about them, is their ability to influence mood, and researchers attempted to quantify their benefits in one study.
Fermented Foods — A Practical Path to Attaining Mental Wellness
The paper, published in Neuroscience & Biobehavioral Reviews, found that fermented foods offer an affordable dietary intervention strategy to enhance your mental health by targeting the gut-brain axis.2 But before diving in further, the researchers established the definition of the gut-brain axis in their research:
“The microbiota-gut-brain axis facilitates a constant bidirectional relay of information from the intestine via the enteric nervous system (ENS) and from the intestinal milieu consisting of microbial communities, microbial metabolites, gut associated lymphoid tissue (GALT), peripheral immune cells and cytokines to the brain and vice versa via the sympathetic/parasympathetic nervous system, neurotransmitters and the circulatory immune system.”
Using this definition as the foundation, the researchers noted that incorporating fermented foods into your diet introduces a diverse array of beneficial microorganisms, resulting in a balanced gut microbiome. Moreover, this approach is convenient and cost-effective compared to taking a supplement, especially for families coming from different socioeconomic backgrounds around the world, as it offers them a way to stay healthy without resorting to adding another layer of expense.3
The neuroactivity of fermented foods is achieved through the introduction of probiotics into the digestive tract during consumption, which interact with the gut-brain axis. Enhanced microbiota diversity ensures a more resilient and efficient gut environment, which directly impacts brain health and function.4
Research also shows probiotics modulate immune and nervous system pathways, as well as impact the hypothalamic-pituitary-adrenal (HPA) axis, which is crucial for stress regulation. Probiotics also influence hormone levels, such as the gut hormones GLP-1, which plays important roles in glucose homeostasis and satiety.5
Going back to the gut-brain axis, fermented foods influence pathways that relay information from the gut to the brain by altering neurotransmitters, neuroactive substances and neuromodulators. These compounds play vital roles in regulating mood, stress response and overall cognitive function. In turn, this helps maintain the human body a balanced state of mental health, reducing the risk of disorders such as anxiety and depression.6
Moreover, fermented foods contain metabolites that reduce the permeability of both the intestinal barrier and the blood-brain barrier.7 A strong barrier prevents harmful substances from entering the bloodstream and reaching the brain, thereby protecting it from inflammation. This is a key factor in preventing neuroinflammation and promoting cognitive resilience.8
Other Effects of Fermented Food on Human Physiology
Fermented foods exert immunomodulatory effects by influencing the levels of circulating cytokines and other immune markers. These benefits help reduce systemic inflammation, which is often linked to various mental health issues. By supporting the immune system, fermented foods create a healthier body and mind.9
The study also points out that probiotics influence the production of hormones such as serotonin, neuropeptide-Y, GLP-1, ghrelin, peptide YY, motilin and somatostatin, which play significant roles in regulating appetite, mood and energy. This promotes metabolic health, which is closely linked to mental health.
That’s because a well-regulated metabolic system aids in maintaining stable energy levels and mood, thus preventing the onset of mood swings and symptoms of depression. Certain probiotic strains also lower stress levels, which is another benefit that promotes better mood and overall health.10
The study underscores that fermented foods influence neurotransmitter levels, including serotonin, which is a key player in mood regulation.11 The slight boost in serotonin levels help enhance feelings of well-being and happiness, reducing the prevalence of mood disorders.
However, note that serotonin levels shouldn’t be always elevated. As noted in my article “Media Twists Findings of Study Linking High Serotonin to Dementia,” elevated serotonin levels will contribute to health issues such as:
- Fibrosis, including cardiac and pulmonary fibrosis
- Impaired thyroid function
- Reduced metabolism due to excessive glycolysis and high lactic acid production
- Reductive and then secondary oxidative stress
- Bizarre, recurring nightmares and post-traumatic stress disorder (PTSD)
Strategies to Nourishing Your Gut Microbiome
Are you eating enough fermented foods? If you’ve been feeling down lately, adding them into your diet will give your mood a nice boost. This strategy subsequently affects the microbiota-gut-brain axis that results in better overall mental health. To help you achieve this goal, here are some practical steps:
- •Make your own fermented foods at home — Creating fermented foods at home ensures you receive fresh, potent probiotics. Homemade options like yogurt, kefir and sauerkraut contain a diverse array of beneficial bacteria essential for a healthy gut microbiome.
Plus, making your own fermented foods is cost-effective and allows you to control the ingredients, avoiding unnecessary additives, genetically modified ingredients and refined sugars found in mass-produced probiotic goods.
- •Avoid pasteurized commercial fermented foods — Commercially available fermented foods are often pasteurized to extend shelf life, which kills the live bacteria necessary for gut health. Instead, opt for traditionally fermented, unpasteurized products sourced from reputable businesses. But again, a better solution is preparing them yourself to maximize the health benefits.
- •Incorporate various fermented foods into your diet — Diversity is key when it comes to fermented foods. Different types offer unique strains of probiotics that work synergistically to enhance your gut microbiome’s resilience.
Include a range of options such as kimchi, natto, homemade yogurt and homemade fermented vegetables in your daily meals. Variety helps ensure a robust and balanced microbiome, which is crucial for optimal gut-brain communication.
- •Maintain consistent consumption — Regularly consuming fermented foods is essential for sustaining a healthy gut microbiome and reaping long-term mental health benefits. That’s because the modern Western diet is filled with ingredients that consistently destroy the beneficial bacteria.12 Therefore, reseeding your gut with probiotics is important.
Make it a habit to include fermented foods in your everyday diet, whether through meals or snacks. Consistency helps maintain gut microbiota diversity, reduces inflammation, and supports stable neurotransmitter levels, all of which contribute to improved mood and cognitive function.
Additional Strategies to Boost Your Mood
While fermented foods are certainly important, there are other strategies available to help boost your mood. One of my top recommendations is getting regular exercise. Not only is it free, it’s also easy to incorporate into your daily routine.
In a study13 published in the British Journal of Medicine, researchers noted that exercise is better than antidepressants when it comes to improving mental health. In fact, according to their calculations, it’s 1.5 times more effective. As noted by lead author Ben Singh, Ph.D.:14
“Physical activity is known to help improve mental health. Yet despite the evidence, it has not been widely adopted as a first-choice treatment … Higher-intensity exercise had greater improvements for depression and anxiety, while longer durations had smaller effects when compared to short and mid-duration bursts.
We also found that all types of physical activity and exercise were beneficial, including aerobic exercise such as walking, resistance training, Pilates, and yoga. Importantly, the research shows that it doesn’t take much for exercise to make a positive change to your mental health.”
Aside from exercise, eating a healthier diet (in addition to fermented foods) will help boost your mood. I recommend adding more vitamin B-rich foods into your diet, as this nutrient plays a role in cognitive function. For example, a B1 deficiency causes irritability and emotional disturbance. On the other hand, a B3 deficiency has been linked to anxiety, aggression and depression.15
Lastly, I recommend you try the Emotional Freedom Techniques (EFT). It’s a form of psychological acupressure that takes inspiration from the concept of energy meridians used in acupuncture. In EFT, you’re tapping certain meridians while voicing out positive affirmations to help uplift your mood. That said, people experiencing the symptoms of depression will benefit from EFT. In the video below, EFT practitioner Julie Schiffman shows you how.

Bypass Big Tech Censors
Two Storms, One Harvest
Every food crisis in living memory has been a one-shock event. The 2008 price spike was a commodity bubble. The 2020 shortages were a logistics failure. The 2022 grain scare was a war on one exporter’s ports. Each time, the system bent, adjusted, and recovered, and each time the experts assured us afterward that global markets are simply too big and too diversified to fail.
What nobody in Washington seems eager to discuss is that 2026 is shaping up to be something the modern food system has never actually faced. Two independent shocks, one climatic and one geopolitical, are converging on the same harvest cycle at the same time. Not sequentially. Simultaneously.
Start with the weather. The Pacific Ocean is currently building toward what forecasters now openly call a record event. NOAA’s Climate Prediction Center puts the odds of at least a strong El Niño near 88 percent, with roughly two in three odds it reaches “very strong” status, the tier reserved for perhaps three or four events in the entire satellite era. Every major global model now projects a median peak in Super El Niño territory, and most of them project it exceeding the 2015-16 event, which until now held the modern record. Sea surface anomalies were already brushing the super threshold in mid-July, months before these events normally peak. The atmosphere has already shifted into El Niño mode, and the event is forecast to crest in late fall and early winter.
This is not about “climate change.” It’s about the standard cycles of weather, and the cycle we’re currently in is one that has likely devastated societies in the past. We’re better prepared as a society today, but not all Americans are equally prepared.
Serious households have started doing the quiet math on their own. Grocery bills tell part of the story, and the forecast maps tell the rest, which is why long-term food storage has moved from fringe hobby to mainstream line item in the family budget, with established suppliers like Heaven’s Harvest seeing demand from people who five years ago would have rolled their eyes at the idea. That instinct is not paranoia. It is pattern recognition, and the pattern is worth walking through carefully.
Editor’s Note: Heaven’s Harvest IS a sponsor, but the warnings of this article are real and would be written even if we didn’t have a survival food sponsor. With that said, those who take advantage of what they offer can use promo code “Patriot” for 15% off.
The Fertilizer Clock Is Already Running
While the Pacific warms, the second shock has been unfolding in the Strait of Hormuz. The conflict with Iran turned the world’s most important energy chokepoint into a contested waterway, and the consequences reach far beyond the gas pump. Roughly a third of global fertilizer trade moves through Hormuz, and the disruption sent urea prices up 86 percent year over year by March, with a 53 percent jump in a single month.
The World Bank projects energy prices rising about 24 percent in 2026 and fertilizer about 31 percent. By its own accounting, fertilizer prices ran 35 percent higher in the first five months of this year than the same period last year.
Here is the mechanism the nightly news will not explain. Fertilizer is not a grocery item. It is a time-delayed input. The nitrogen a farmer in Iowa or Punjab could not afford to apply this spring does not show up as a problem this spring. It shows up as a thinner harvest six to twelve months later.
The World Bank’s own food security brief concedes that the effects of reduced applications earlier this season “are likely to become visible only later in harvest outcomes.” Translate that from institutional language into plain English and it means this. The damage is already done, it is already in the ground, and we are simply waiting for it to arrive on the shelf.
Now check the calendar. Six to twelve months from the spring planting season lands us squarely in late 2026 and early 2027. Which is precisely when the strongest El Niño in the instrumental record is forecast to peak, bringing its signature droughts to Southeast Asia, Australia, southern Africa, northern Brazil, and South Asia, the very regions that grow the world’s rice, sugar, and oilseeds.
The World Bank warns openly that a strong El Niño “could disrupt multiple crop belts simultaneously” on top of the conflict-driven input costs. Their baseline projection assumes the Middle East disruptions ease by autumn. What in the last two years of Middle East history suggests that assumption is safe?
The System Has No Slack Left
The comfortable answer is that global markets always adjust. But adjustment requires slack, and the slack is gone. Global cereal production is expected to decline from last year’s records even before El Niño does its work. The UN World Food Programme, hardly a den of right-wing preppers, is calling this the most significant disruption to its supply chains since Covid and the invasion of Ukraine, and its supply chain director put the stakes bluntly.
Today’s supply chain challenges are tomorrow’s hunger crisis.
There is also a political dimension that markets cannot price. When food gets scarce, governments do not behave like economists. They behave like politicians. Export bans, hoarding mandates, and panic buying at the national level turned the modest rice shortfall of 2008 into a global crisis, and analysts are already warning that import-dependent nations are the first dominoes.
The 2015-16 Super El Niño, a far weaker event than what is now forecast, threw tens of millions into food stress across Africa and Asia. This one is projected to be stronger, and it arrives with fertilizer already rationed by price and shipping lanes already contested by missiles.
What Joseph Knew
Scripture does not treat preparation for lean years as faithlessness. It treats it as wisdom delivered in advance to those willing to act on it.
Behold, there come seven years of great plenty throughout all the land of Egypt: And there shall arise after them seven years of famine; and all the plenty shall be forgotten in the land of Egypt.
Joseph did not respond to that warning with a hashtag or a committee. He stored grain during the years of abundance, and when the famine came, Egypt stood while its neighbors begged. The lesson is not that famine is certain. It is that the time to prepare is precisely when preparation still looks optional.
Nobody who filled a pantry in a year of plenty has ever regretted it, and nobody standing in an empty aisle has ever been glad he waited for certainty.
None of this calls for panic, and panic is the enemy of sound judgment anyway. It calls for the same unglamorous prudence our grandparents considered ordinary. Keep some cash margin, know your local growers, and put real food in deep storage while it is cheap and available, because the entire arc of this story is that cheap and available is a closing window.
Families looking for a straightforward place to start can visit Heaven’s Harvest and use promo code Patriot for 15 percent off long-term storable food. The forecasts may yet soften, the strait may yet reopen, and we should pray they do. But hope is a fine thing to hold and a foolish thing to eat.
