Human Cells vs Bacteria: Microbiota in Your Body
Your body is 90% bacteria. So that means by 10 to 1, colonies of bacteria outnumber your human cells. Put it another way: we are borderline bacteria.
But there shouldn’t be negative connotation to this. Bacteria are instrumental in breaking down sugars, digesting food and protect against infections.
And the reason is because your body functions best by evolving with both human cells and bacteria. You wouldn’t be who are you today if it wasn’t for the underappreciated bacteria.
But lately we’ve recounted only to find that it’s more like a ratio of 6 to 4. Instead 57% of your body is bacteria, fungi, archaea and viruses. And the remainder is about 43% human cells.
A healthy microbiome
100 trillion microbes reside in your body. They live inside your bodies such as in your colon, gastrointestinal tract and lungs). And they live on the exterior of your body such as on your skin, mouth, naval and under arms.
For example, bacteria interact with cells in your intestinal tract. They live in a delicate balance helping cells absorb energy, strengthen immune system and protect against infections.
If one bacteria type gets out of balance, it begins to outnumber others. In this case, doctors provide antibacterial medicine because you feel ill from the imbalance. Antibacterial medication like amoxicillin reduces the problematic bacteria and has an overall regulating effect to the number of bacteria.
But anti-bacteria medicine can have a disturbing effect in the microbiome and cause more serious problems. This is why treating imbalances with probiotics has become a major field research. These beneficial microbes assist in treating disease.
