hey guys dr. Berg here in this video I want to  discuss probably one of the most important body  

systems that you have it’s the digestive system  ok so you have 33 feet of intestines and that’s a  

like you can mention a water hose in your backyard  it’s a very long hose and it’s all wrapped around  

and there’s a lot of things that happen from start  to finish so let’s just time to take from the top  

you’ve got the stomach here which normally what’s  interesting about the stomach is that people don’t  

realize how acid the stomach should be if you  understand pH neutral is 7 and it goes down to  

be more acid and higher to be more alkaline for  every number let’s say we go from 7 to 6 going  

down that’s 10 times more acid so it it compounds  so you can imagine a pH of 1 to 3 that is super  

super acidic okay that’s what the stomach should  be normally and the stomach actually helps you  

release the stomach releases the acid triggers  enzymes that then help you break down protein so  

they have very powerful proto lytic enzymes so  if there’s a problem with the valve on the top  

of the stomach then that enzyme gets up into  the esophagus they can literally digest your  

tissues up into your throat so it’s that powerful  it helps you absorb minerals so if you don’t have  

the right acid in your stomach you can’t absorb  like iron you become anemic like even b12 will  

not be absorbing either and that’s another type  of anemia it also kills microbes because microbes  

have a hard time living in that acid and either  even h pylori which is a very nasty bacteria that  

causes ulcers and other issues if your stomach is  very acidic that thing will stay in a mission or  

not invade your tissues but if the stomach is not  asked enough it will not release these to other  

organs called the pancreas and the gallbladder so  what controls a pancreas in and the gallbladder  

is really the pH of the stomach pH of that stomach  also controls the valve of the top of the stomach  

so without that stomach being acidic you you  can get GERD acid reflux and then people take  

any acids which is the exact opposite but what  happens if you you can’t release the pancreas  

now we don’t we don’t get the release of enzymes  so the pancreas has all these different enzymes  

for carbohydrates proteins fats collagen you name  it and it’s constantly released depending on which  

you eat so signals from your mouth are telling  the pancreas what to release and what to create  

when you start eating so so we have this enzyme  breakdown and then we have the gallbladder release  

bile bile helps you break down fats break down fat  so you can absorb fat side with vitamins vitamin  

A D and K and then also help you it helps you  detoxify certain chemicals in the liver so without  

the gallbladder we can’t get that full detox  let these two work together and then the bile is  

alkalyn so it helps to neutralize this incredibly  strong acid coming into the small intestine so if  

we didn’t have the bile we couldn’t neutralize  that and you would get an ulcer in your small  

intestine and then we have the pancreas that also  makes this other alkaline fluid called bicarbonate  

that helps neutralize the acid at this point too  so we go from a strong acid to a very alkaline  

fluid inside the small intestine so the small  intestine is alkaline okay and it’s so funny  

when people say well you need to be alkaline well  what part of the body you’re talking about because  

your stomach better not the alkaline definitely  the small intestine should be alkaline but the  

large intestine should be acidic so you have  different PHS so now in the small intestine this  

is where 90% of the digestion occurs and you have  helped though you have microbes you have a lot of  

microbes in fact in your body you have a thousand  trillion bacteria or microbes in your body outside  

and inside that’s a thousand trillion that’s a lot  you only have a hundred trillion cells so these  

bacteria or these microbes have are ten times  more than your own self so if you take a body  

it’s mostly microbes so but they’re very small  so you don’t there’s like probably about three  

or four maybe five pounds of microbes per body  weight but the microbes basically help you break  

down your food and help so you can absorb the food  there’s thousands tens of thousands of different  

strains of microbes in your gut you have good  bacteria and then you have bad bacteria they’re  

called pathogenic now antibiotics destroy both  good and bad bacteria what’s happening now is  

the bad bacteria is adapting to the antibiotics  and they’re becoming more resistant so now the  

antibiotics don’t work but the good news is  this that the good bacteria also adapts to the  

antibiotics if it didn’t you’d be probably be dead  by now so your microbes are very intelligent and  

they have developed new strategies of surviving  so if you take a let’s say someone comes in your  

house and they try to steal something and then you  take a bat and you whack them right well the next  

time they come in their house they’re they wear a  helmet so these microbes basically have different  

ways of adapting to survive one of the interesting  strategies some of these microbes pulled off is  

they basically can mimic and adapt to your vitamin  D receptors they mimic the vitamin D receptor so  

when your vitamin D goes into the wrong receptor  it doesn’t work anymore so it’s just as fascinated  

because you need vitamin D for the immune system  so there’s all these different types of strategies  

that use one type of micro adapted without a  cell wall so they can move into the joints and  

then they can travel and they can do this and they  can hide so your immune system can’t detect them  

very intelligent sneaky little guys but thank  goodness that our good bacteria also adapt so  

we have 90% of the nutrient nutrition absorption  occurs at this level with other another thing  

that’s interesting about this is that you  have something called the enteric nervous  

system so you have the sympathetic which is a  flight-or-fight that’s like the stress nervous  

system and then we have the parasympathetic which  is part of the rest and digest which controls a  

lot of this - that’s that’s kind of like the  opposite of the stress nervous system but then  

you have the enteric which controls like all this  intestines and the peristalsis the pumping action  

of the whole thing and if years someone cut your  spinal column for example you could this will  

still work because it’s an independent nervous  system it can work on its own that’s what I call  

the second brain but the challenge is that a  lot of the information that happens down here  

is transmitted up to the brain so whatever’s going  on your digestion can affect your mood you could  

it could have create depression anxiety and a  lot of tension in your neck and even a lot of  

headaches so it’s interesting how the digestion  can affect your mood and also your mood could  

affect your digestion both ways because it’s a  second brain the bacteria also makes a lot of B  

vitamins so what happens when I see people with  vitamin B deficiencies it’s not because they’re  

not consuming them is because they don’t have  the microbes or they they don’t have the good  

digestive system to absorb those vitamin B  over those B vitamins or they they make them  

but they can’t get absorbed because the surface  lining of the intestines is damaged so I’ll get  

to that in a little bit but what these microbes  eat or consume is fiber preferably when we want  

to feed them a vegetable fiber and they turn it  into something called butyrate which is a type of  

acid that then will feed the colon cells so it’s  it’s interesting these microbes actually exchange  

with us we help them they we provide a house and  they give us food as well so that’s what happens  

in the small intestine and the large intestine is  mainly responsible for reabsorption of water and  

minerals but this is where you have the highest  concentration of microbes so without the microbes  

here you’ll get diarrhea okay the little little  roots that occur in a small intestine are called  

little villi they’re upside down roots and that’s  where it absorbs and you have like a million  

bacteria per millimeter like a real small surface  area there’s a so many compacted microbes in there  

that are supposed to help you absorb and write  when it gets absorbed it goes right into the  

lymphatic system 80% of your lymphatic system is  surrounding your intestines so 85% of your immune  

system is really connected to your gut and it’s  there and it’s kind of like immigration to give  

these microbes a stamp of approval or not approval  to not let them through so there’s a barrier there  

that resists microbes that are unfriendly so  when you destroy these little so-called villi  

or little roots you get this small surface area  where you now you can’t you lose your immigration  

so now my unfriendly microbes can innervate and  start to go into the lymphatic system and create  

health for the immune system that’s where you get  autoimmune diseases that’s where the immune system  

you know starts giving the wrong information and  attacking it’s not creating antibodies for your  

own tissue it’s like self attack so you have a  lot of inflammatory conditions that originated  

from this lining that you lose the structure  okay so there’s a couple things that you can  

do number one you have to build up the flora and  I think the best way is to take something called  

effective microbes I’ll put a link down there  I’m not affiliated I don’t get any Commission’s  

or anything but I’ll put a link down there of  effective microbes and you can check it out but  

effective microbes is the symbiotic a group of  microbes that basically all live on each other  

so they kind of work together and you want to  take very very very small amounts starting out  

because if you have too many unfriendly strains  you can create a war so you want to take them  

right before you go to bed and then they’ll grow  in your system over a period of time so effective  

microbes are very important and then to retrain  your immune system your t-cells and start to put  

back that immune system I recommend something  called colostrum and again I’ll put a link down  

there below I’m not affiliated with any companies  but this is a really good thing too your immune  

system and it’s really really good for rheumatoid  arthritis it’s good for inflammation it’s good for  

autoimmune it’s good for allergies it’s really  good for sinus mucus it’s good for any type of  

inflammatory condition but I will say when you  take this start off taking very small amounts  

maybe 1/4 of a teaspoon before bed why because if  you don’t have a good immune system you’re going  

to stir up a hornet’s nest and you’re gonna get  more mucus that it’s gonna kick in there so you  

always want to start very small over a gradual  period of time to start introducing these 2  

things so and I also recommend al glutamine -  those three are really good to start building  

up the intestinal wall and then over time you’ll  start getting your immune system back ok so I  

hope that kind of gave you a summary of how this  digestive system works and put your comments below
