Probably the first thing you should know about your gut, is that it’s not about a pot belly. That’s more of a slang usage for belly-fat.
And there’s a heck of a lot going on inside that 5-foot (or so) long tube.
But first comes the 20-foot (or so) long small intestine.
It does most of the heavy lifting regarding absorbing nutrients and water.
But the colon is the really magical (if I can use that term, without sounding like a kook) organ.
Not magical in the arcane sense, but more in the miraculous sense.
At least it is to me. Stick with me and see if you agree…
Fact Bundle 1 – We Have Two Brains
- The colon is often referred to as the “second brain” by scientists
- This is because it contains millions of neurons that generate neurotransmitters like serotonin
- In fact, the gut sends more information to the brain, than the brain sends to the gut
Fact Bundle 2 – We Are Really “Us”
- An adult human is said to have approximately 10 trillion cells in their body
- The colon of an adult human contains approximately 100 trillion microorganisms
- The combined weight of these bacteria and fungi averages about five pounds
- So, the average person (of any age beyond infancy) has 10 times more microorganisms than cells in their body
- These microorganisms include a wide range of species – more than 1,000 known so far
- Thus, their DNA outnumbers the human “host’s” DNA by 10 times
- And their genes outnumber human genes by 150 times
