This piece explores how closely our gut microbiome is connected to our overall health. Surprisingly, the number of bacterial cells in our body actually outnumbers our own cells, mostly in the gut. But these bacteria do way more than just help with digestion. They also affect our mood and mental health because gut bacteria help produce serotonin, a key chemical for regulating emotions. When the balance of these bacteria is off, it can lead to various health problems like autoimmune diseases and mood disorders. That is why keeping our gut healthy is so important. We will also look at how what we eat, especially probiotics and prebiotics, can build a strong and diverse microbiome, boosting both our body and mind.
