Good Bacteria vs. Bad Bacteria: Meet Your Gut Microbiome

Your gut is home to trillions of bacteria — more than all the cells in your body combined.
“Good” bacteria help digest food, make vitamins, and fight harmful microbes.
“Bad” bacteria can cause bloating, infection, or inflammation when they overgrow.
A balanced microbiome keeps digestion smooth and immunity strong.
Diet, stress, and antibiotics can shift this balance quickly.
Fermented foods like yogurt, kimchi, and kefir support healthy gut bacteria.
Good microbes produce short-chain fatty acids that nourish your intestinal cells.
Everyone’s gut microbiome is unique — like a bacterial fingerprint.
An unhealthy gut can affect mood, weight, and even skin health.
When your microbes thrive, your whole body feels the difference.
