Stress and anxiety can be reduced over time in one key way, study suggests

Natural probiotics, which are beneficial bacteria, can be found in fermented foods like sauerkraut, cheese, and kimchi, as well as in beverages such as kombucha. They are also available in supplement form as tablets and pills, as per information from the Cleveland Clinic. These probiotic supplements contribute to the friendly bacteria already present in your body, helping to combat harmful bacteria and strengthen your immune system against infections, the clinic’s website explains.

A new research study, published in the journal npj Mental Health Research, aimed to explore how probiotics may enhance mental well-being. Katerina Johnson, a research associate at the University of Oxford and one of the study’s co-authors, highlighted the gut-brain connection as one way gut bacteria can impact emotions and behaviors through mechanisms like the vagus nerve, immune system, and hormones.

Lindsay Allen, a registered dietitian nutritionist from Back in Balance Nutrition in Florida, emphasized the importance of maintaining a healthy gut with a diverse population of microorganisms. She noted that the number of these beneficial bacteria cells in our bodies surpasses that of human cells, indicating the potential of probiotics to positively influence our well-being.

During the study, one group of young adults took probiotics daily for a month, while another group received a placebo. Participants were required to submit a daily mood report, which revealed that after around two weeks of consistent probiotic intake, negative feelings such as stress and anxiety decreased. The study, which utilized daily mood tracking as a unique approach, detected the mood-enhancing effects of probiotics in participants.

The researchers found a correlation between regular probiotic consumption and improved mood through the analysis of daily mood reports, psychological questionnaires, and emotional processing tasks. Laura Steenberg, a study co-author and assistant professor at Leiden University, remarked on the study’s ability to identify the positive impact of probiotics on mood by monitoring participants’ daily feelings.

The study results indicated that probiotics could alleviate negative emotions like stress, anxiety, and fatigue within two weeks of consistent intake, compared to the placebo group. While previous research mainly focused on the effects of probiotics on depression, stress, and anxiety, limited information exists on their influence on positive emotions. The study suggested that probiotics might reduce negative moods without affecting positive feelings, potentially offering a significant advantage.

Despite the promising findings, the researchers cautioned that probiotics should not replace antidepressants or psychiatric medications. They recommended thorough testing to determine individual needs and advised consulting a healthcare provider before incorporating probiotics into one’s diet, especially for individuals with underlying health conditions. Additionally, incorporating foods rich in polyphenols, such as berries, apples, spinach, and kale, can promote a diverse microbiome and support the growth of beneficial bacteria. Live probiotic foods like coconut milk kefir, pickles, and yogurt can also contribute to a healthy gut.

In conclusion, while probiotics hold potential for improving mental health and overall well-being, they are not a substitute for professional medical advice and treatment. It is essential to consult with a healthcare provider before making any significant changes to your diet or supplement regimen to ensure safety and efficacy.
