Secretly buy a few bottles of yogurt and put them in the refrigerator to deal with your girlfriend's emotional disorder!
A recent study revealed the relationship between lactic acid bacteria, the star bacteria of the gut microbiota, and mood changes under environmental stress (e.g., anxiety, depression, etc.).
When you think of probiotics, you always think of a variety of advertisements for probiotic-rich products. In the scientific research community, the intestinal flora, including probiotics, has been "hot" for more than ten years, and it is a top research hotspot every yearmechanism innovation, intestinal flora". Research on probiotics and gut microbiota emerges every yearIn our previous tweets, we have also introduced the intestinal flora in fermented foods to reduce the incidence of cardiovascular disease, and yogurt can modulate the intestinal flora to be anti-inflammatory**. And the benefits of probiotics don't stop there!
Alban Gaultier's group in the Department of Neuroscience at the University of Virginia published a paper titled "Lactobacillus from the altered schaedler flora maintain ifn homeostasis to promotebeh**ioral stress" in the medical journal Brain Beh**ior and Immunity resilience. In the study, the researchers found that the main motivator for resistance to environmental stress and anxiety in mice was the IFN levels maintained by the lactobacilli themselves by colonizing specific lactobacilli in germ-free mice, and this new finding provides new ideas for the future development of probiotic supplements** for depression and anxiety.
To study the relationship between probiotics and anxiety, the researchers used the UCRS method to model stress stress in mice for 3 weeks. Increased silence and repetitive behavior in the tail suspension test and the Nestlet shredding test confirmed the success of the modeling. The 16S sequencing showed that the intestinal flora was dysbiosis and the content of lactic acid bacteria was reduced. To further investigate the relationship between dysbiosis and anxious or depressive behavior in mice, the researchers transplanted the gut microbiota of stressed mice into germ-free mice. After 2 weeks, the maze test found that the transplanted mice showed more anxious behaviors. This suggests that the gut microbiota can alter environmental stress-induced mood disorders and directly modulate behavior.
To investigate how the gut microbiota of stressed mice triggers anxiety and depression-like behaviors in germ-free mice, the researchers performed untargeted metabolomics testing and found a significant reduction in IFN. IFNs play a key role in stress-induced anxiety and depression. The researchers also found that the absence of lactic acid bacteria led to changes in depression and anxiety-like behaviors, and that the reduction of IFN was strongly correlated with the strength of the mice's resistance to environmental stressors. Circulating IFN can modulate behavioral responses, a process regulated by the gut microbiota.
This study found that lactic acid bacteria themselves have the miraculous effect of regulating mood and resisting environmental stress and anxiety!Just like a superhero, through the secret of IFN**, lactic acid bacteria escort our mental health.
In fact, we often come into contact with lactic acid bacteria in our daily life. It is found in yogurt and all kinds of fermented foods. This is consistent with the results of a study we heard earlier about the effects of fermented foods on reducing stress.
So, if you're feeling a little stressed or even a little anxious, try drinking more yogurt. One glass is not enough, so let's have two!In this way, your mood may be as sweet as eating sugar!
