10 Fascinating Facts about our Gut and Microbiome

I’ve recently read the book Gut by Giulia Enders and it was incredible. Such an informative and funny book, the illustrations were amazing and the whole book made a complex topic really easy to understand.

  1. We have 2 anal sphincters – 1 internal which works involuntary, 1 external of which we have voluntary control.
  2. Saliva is basically filtered blood – salivary glands sieve blood keeping back red blood cells. Calcium, hormones and some other products of our immune system enter the saliva.
  3. Anything absorbed in the final part of the large intestine does not go to the liver for detoxifying because not much is absorbed at this point. This does mean suppositories are able to contain less medication and take effect quicker.
  4. Tooth enamel is the hardest substance produced by the human body.
  5. Unborn babies swallow up to half a litre of amniotic fluid a day.
  6. P6 acupuncture point stimulation can help reduce nausea – this point is 2-3 finger breadths below the wrist between the two tendons.
  7. Of our entire microbiome, 99% of microbes are found in the gut.
  8. When we’re born 100% of our cells are human; this reduces to 10% with the other 90% being microbes.
  9. Female threadworms lay their eggs around the outside of the anus when we’re asleep because we are relaxed and unconscious so we scratch and, inevitably, they end up in our mouths making their way through our digestive system in time for the eggs to hatch.
  10. Most probiotics are currently isolated species of bacteria grown in labs that disappear from the gut when we stop taking them.

It’s a great read and I highly recommend it. If you can access a copy at your local library check it out. In case you want to buy it for yourself or as a gift for someone you can get it here*.
