Alkaline upper intestine

[Guest guest]

I got this link from another group:

http://www.naturalmedecine.org/italiano/cure_natur/distribuzione_flora.htm

It shows the various bacteria that live in the different levels of the

intestine.

Now, the thing is, it shows the upper intestine as alkaline, which I'm

told is for fat digestion. But lactobacilli are acid loving. And they

create acid.

So does this mean that the LB don't colonize the small intestine?

Or that they do and thereby make it more acidic? (in the picture

it shows lactobacillus as being in the small intestine, I think, it is

hard to read).

This picture also shows the LB being in the STOMACH, which

I'd never heard of. I guess until recently people thought the stomach

didn't really support a lot of bacteria.

Any comments?

*******Heidi, this is a great schemata - thanks for posting it! If you click

on the links at the bottom it launches a new window with a readable chart of

what bacteria are in each area of the digestive tract and it lists the

colony size. apparently, the colon has the highest concentration of LAB

(lactic acid bacteria), and the lower end of the small intestine has the

second highest concentration. according to this, LAB DO colonize the small

intestine and the concentrations vary from section to section.

the scale at the bottom shows that putrefication ocurrs toward the alkaline

end of pH, so perhaps the LAB in the colon prevent putrefication. also, in

one of the links i posted recently to beyondprice, it was explained how the

various colonies often work symbiotically in that the metabolites of one

type of bacteria feed another type which then produces metabolites that feed

another type. so maybe the lactic acid produced by LAB is then transformed

into something less acidic by another type of bacteria..?

as far as the stomach goes, the bacteria levels seem to be from 0 to low

levels of a handful of types. it's probably too acidic for most.

If you click on the link at the bottom of the page it takes you to a chart

titled:

SOME OF THE MAJOR LACTIC ACID BACTERIA USED IN FERMENTED MILK PRODUCTS

http://www.naturalmedecine.org/italiano/cure_natur/fermenti_latticini.htm

and then if you click on 'page 2' it takes you to a chart of various

bacteria and their influence on the host. not sure why lactobacilli aren't

in the most symbiotic column..?

recently, i read somewhere that it was found that humans had varying types

and concentrations of a variety of gut microbial colonies. which, of course

makes sense, since we have varying diets. but i wonder how much our gut

microflora profiles differ? do i have 50-100 of different types of bacteria

that someone else doesn't have? or vice versa? there must be SOME types that

are ubiqutous in the human GIT, such as some LAB species..?

Aha! I didn't click enough! Thanks!

That's what I'm wondering too. If you drink kefir every day, I'd think

you have a MUCH different profile.

Most food poisoning happens in the upper intestine, where it is more

alkaline (and most of the 'bad' bacteria are alkaline-loving). But taking

probiotics helps a LOT with food poisoning, so I'd think they must

colonize there more when you are eating more probiotic foods.

And what happens to someone on antibiotics? How many of those

bacteria are killed? And what about all the food preservatives

we eat? They are designed to kill bacteria, and most of the modern

foods have tons of preservatives.
