Do you experience stress or anxiety? As many as 33% of people will have stress affect them in their lifetime. A review of studies published in the General Psychiatry journal suggests that taking probiotics, non-probiotic foods and supplements can help aid in symptoms of anxiety.
Probiotics function to aid in the immune system and metabolism through the gut-brain axis. Recent studies are suggesting by regulating gut bacteria could treat mental disorders that are related to stress. Other health benefits of probiotics include stronger immune system defense, better digestion, weight loss, leaky gut repair, elevated energy and alleviating inflammatory bowel disease.
Some foods have good, natural living probiotics that combat bad gut bacteria and prevent them from colonizing with our intestinal microbiota. Foods with probiotics include kefir, natto, yogurt, apple cider vinegar, miso, traditional buttermilk, tempeh, pickles and kimchi.
About half the studies (11 out of 21) showed to be effective on anxiety symptoms simply by regulating gut bacteria. The studies also suggested that introducing too many different types of probiotics could have negative effects. These bacteria may have cancelled each other out for them to work effectively.
Since these were peer-reviewed observational studies we can't establish cause and effect. My personal recommendations on stress and anxiety reduction are: controlled breathing such as meditation, active lifestyle, probiotics and Full Spectrum CBD (cannabidiol).
