The days grow shorter and darker in autumn and winter. This can affect some people's moods, and many suffer from depression without realizing it. But it's not just the weather that can influence your mental state; your gut bacteria can too. This blog post will explain what your gut bacteria have to do with your mood, or even depression, and what you can do about it.

The Gut-Brain Axis – The Connection Between Gut and Brain
The gut communicates with your brain via the gut-brain axis, but the brain also "speaks" to your gut. The gut-brain axis consists of nerve pathways that run from the gut to the brain and vice versa. However, most nerve signals are sent from the gut to the brain.
Studies suggest that mental health can be negatively affected if certain bacterial strains are missing in the gut. This is closely linked to depression, anxiety, and increased stress.
These bacteria also have a strong influence on our eating behavior, as they subconsciously regulate our appetite. Important bacterial strains associated with the gut-brain axis include Lactobacillus acidophilus, Lactobacillus helveticus, Lactobacillus casei, Lactobacillus plantarum, Lactobacillus paracasei, and Bifidobacterium longum. They influence brain activity and can affect your mental state.
Gut bacteria affect the release of stress hormones and the production of our "happiness hormone" serotonin, which controls our moods and emotions. It can also have an antidepressant effect and even promote better sleep. Stress can also impair the protective gut barrier, allowing harmful substances to enter our body. Experts refer to this issue as leaky gut syndrome.
What You Can Do for a Healthy Gut Microbiome and Balanced Mental Health
Eat a varied and wholesome diet, ideally with plenty of organically grown vegetables, fruits, fiber-rich grains, as well as seeds, grains, and nuts. Healthy fats, such as those in olive oil, should not be missing.
Drink at least 2 liters per day, preferably still water or unsweetened tea. This amount of fluids is especially important when consuming fiber.
Avoid processed foods, fast food, and sweets, as they can promote inflammation in the body and feed the "bad" bacteria in the gut. Fermented products such as miso, pickled vegetables, or kimchi can also positively influence your gut microbiome.
The use of specially formulated biologically active supplements further supports gut health. By simultaneously taking prebiotics (fibers) such as acacia fibers or inulin, you can significantly enhance the effect of probiotics. Prebiotics serve as food for the "good" gut bacteria, further promoting gut health.
Conclusion
Depression, stress, and anxiety cannot always be avoided, but a balanced, fiber-rich diet, along with prebiotic and probiotic supplements, can strengthen the gut and positively influence the gut-brain axis.
