And so plaque of cholesterol would deposit, it would heal, and then it would be reabsorbed, right? But no.
What I'm saying is that 99%, if not 100% of chronic diseases are either directly initiated by gut injury or related to gut injury. So what do we do? So what we do is we need to, first of all, when people come to me, the first thing I do when a chronic problem comes to me is I put them on a gut repair program. Even before I get the blood tests. Really?
If I send blood tests or whatever tests are needed. So I only send tests when they're really needed, in my opinion. Before the blood tests come, many times, already with a gut repair program, by the time the blood results are there and you have the second appointment, the problem is already even much better or completely gone in two or three weeks.
Yeah.
Well, sometimes I do blood work anyways. Okay, but what you're saying is... There's a lot of things to consider, but gut repair is... That's where the Achilles heel of human health exists. And I'm going to explain it to you. Oh, sorry, this is yours. Yeah, I brought a model of a part of the intestine. This is the intestinal wall. And these are the microvilli.
An anatomical model.
Okay, go ahead. So the gut is a tube, right? And the tube has a surface, right? And this surface in the gut is increased by foldings, which are called villi and microvilli. So... Why does the body, or why did the body evolve to do that? What we think is that it's to increase the contact surface of the intestines because there's a lot happening there that needs to happen, right? Okay.
digestion and absorption, right? And life depends on it in nature. Sustenance in food is very important. So the gut is, in all animals, is a really important organ and system, right? So what happens is this surface, if we now get an intestine and iron it out, and we flatten out all this villi and microvilli, the surface of your intestine would be
Between one and two tennis courts of size, one and a half. I mean, you're little, so probably one and a quarter. Oh, yeah. I'm a little bigger, so one and a half. Some people have two tennis courts, surface of an intestinal wall.
Between one and two tennis courts, depending on your size and size. You know, and age and sex. Wow. Yeah. And this is what happens. Each microvilli has a blood supply system and a nerve and muscle system. This yellow here is the nerves, this artery and vein, and this is the wall. So this is inside the body and here would be outside the body. Here's where the food would come.
right this is obviously a tube right and this is just a little part of the wall so here's where the food comes so this is where the bacteria would live right and once it passes see this there's a one layer of cells here this one layer of cell is like a brick wall each cell is like a brick and it's stuck to the next cell and it's sent right next to it by cement This is called the tight junction.
Now, why did the body design this wall so hermetic? It's because it doesn't want undigested food or even digested food to go directly into the blood. The cells are intelligently selecting The small, broken down, digestion breaks down proteins into amino acids, carbohydrates into simple sugars, and fats into fatty acids.
So those little components are the ones that these cells select, absorb, meaning they go through the cell, the nutrients, and they're dumped into the blood. But if the cement between the cells is broken down and there's a gap between the cells, this is what's called the leaky gut. So what happens is everything that's happening outside the body,
meaning inside the digestive tube, it's outside the body. Now, many things are just seeping in without the intelligent selection of the body. The body selects only the building blocks, amino acids, fatty acids, simple sugars. But when these gaps are broken and the gut is leaky or hyperpermeable, undigested food starts, peptides or proteins start passing through. And here...
In the gut is where we're most exposed to external stuff because your skin touches your clothes and the air, and if you're in the swimming pool, the water. Your lungs is only water. That's all the limits between the outside of the body and the inside of the body. Your skin, your eyes, your lungs, and your intestines. What's happening in your intestines? You're dumping...
thousands of kilos in your lifetime of stuff there that the body has to deal with. So the body is exposed to external stuff in the gut more than anywhere else. So that's why the body deposited or sent all its troops, like 70, 80% of our immune system is in the gut. See these cells here?
This is one cell, it's showing you one cell from the immune system. So the immune system is in the gut wall, but it's also in the blood.
Leaky gut and changes in the microbiome are the gut problems, the gut disease, I mean, the gut injuries or the gut problems that trigger most diseases. And I'm going to explain to you, for example, autoimmune diseases, right? What's happening is the immune system works by recognizing surfaces. It's called the HLA system. human lymphocytic antigen system, right?
Antigens are surfaces that your body, each immune system cells is like a computer and it has like a scanner. And it scans surfaces all the time, all day long. And then it compares it with its record. And if there's a certain, and genetically you have all the surfaces that are acceptable to you, like your proteins and your muscle.
that you have them, you have like a code, right? So the immune system scans the surface of what it sees, and if it doesn't recognize it, it attacks. So what happens is when you absorb amino acids into the blood, It doesn't have a surface. Amino acid is a building block, but a protein already has a surface. So we have many amino acids together.
