Gut - The Inside Story of Our Body’s Most Underrated Organ

How much do I want to read more? 7/10

I already started reading this book like 3 years ago, but didn't take note, so I have to read it from begining again.
It's good and complementary with other readings I have in progress, telling the importance of the gut on our health and our brain.


I WAS BORN BY cesarean section and could not be breast-fed.
When I was seventeen, I developed a small sore on my right leg. Three weeks later, my entire leg was covered in sores. Soon they spread to my other leg, my arms, and my back.
No doctor was able to help me.

I stopped eating dairy products, cut out gluten almost entirely, swallowed various bacterial cultures, and generally improved my diet.
With a few tricks, I finally managed to get my condition under control. This success gave me a lift, and I experienced with my own body that knowledge is power.

I was at a party where I ended up sitting next to a guy who had the smelliest breath I have ever smelled.
not the sugary, fetid funk from the mouth of an elderly aunt with too sweet a tooth.
After a while, I moved away and sat somewhere else. The next day, he was dead. He had killed himself.
I wondered if it could have been a diseased gut creating that smell, and if so, could a diseased gut also have affected that man’s psychological state?

I discovered there was an entire branch of medical research investigating the links between the gut and the brain.
The influence of the gut on our health and well-being is one of the new lines of research in modern medicine.
what an extraordinary organ the gut is. It accounts for two-thirds of our immune system, extracts energy from sandwiches and vegetarian sausages, and produces more than twenty unique hormones.

It is now generally accepted in scientific circles that people with certain digestive problems often suffer from nervous disorders of the gut.
Their gut then sends signals to the part of the brain that processes negative feelings, although they have done nothing bad. Such patients feel uneasy but have no idea why.


THE WORLD IS a much more interesting place if we look beyond what is visible to the naked eye.
The brain gets most of its input from our eye. we overlook all sorts of wonderful things.

There is a constant buzz of activity beneath our skin. We are perpetually flowing, pumping, sucking, squeezing, bursting, repairing, and rebuilding. A whole crew of ingenious organs works so perfectly and efficiently together that, in an adult human being, they require no more energy than a 100-watt light bulb. Each second, our kidneys meticulously filter our blood—much more efficiently than a coffee filter—and in most cases they carry on doing so for our entire lives.
Our lungs are so cleverly designed that we use energy only when we breathe in. Breathing out happens without any expenditure of energy at all. If we were transparent, we would be able to see the beauty of this mechanism: like a wind-up toy car, only bigger, softer, and more lung‑y. While some of us might be sitting around thinking “Nobody cares about me!”, our heart is currently working its seventeen-thousandth twenty-four-hour shift—and would have every right to feel a little forgotten when its owner thinks such thoughts.

we could watch as a clump of cells grows into a human being in a woman’s belly. We would suddenly see how we develop, roughly speaking, from three tubes.
