Probiotics research published

Research to find out whether bacteria from probiotic products survive in

people's digestive systems has been published today by the Agency.

The study was designed to find out if and where these bacteria break down as

they pass through the digestive system. The study did not look at whether

probiotic products have an effect on health.

Findings suggests that not all strains of bacteria used in probiotic

products survive through the entire digestive system, although at least one

strain in each of the products tested survived beyond the stomach. The

research does not show if or where probiotics might have an effect.

Scientists at the University of Reading used laboratory models of the human

gut to imitate the conditions of the stomach, upper intestine and lower

intestine.

Probiotic bacteria found in 11 different probiotic products were tested.

Products included dairy and fruit juice containing live bacteria and dry

preparations in the form of tablets, capsules and powder. All bacteria used

were grown and their numbers standardised before each experiment began.

The researchers used a model to simulate the effect adding probiotic

bacteria would have on the total number of bacteria in a typical human

digestive system. Overall, adding bacteria from probiotics did not change

the total number of bacteria in the gut.

I can't speak to the validity of this experiment, but Gray (The Colon

Health Handbook) had a number of unusual (at least not commonly held) views

of colon health, and one was that probiotics, while helping symptoms during

use, did absolutely nothing to foster long-term growth of gut colonies. He

did have a receipe for rejuvelac, but advised taking it short term only, and

only when freshly made (before the lactic acid wastes built up.)

Actually Nestle did some good research on this at one point, and it turns

out that most probiotic bacteria do not, in fact, live very long in the gut.

This jibes with my experience: I have to do probiotics daily or the

effect wears off. Which is also why it's important to have probiotic FOODS

you eat with the meal .. like kimchi and kefir beer. Kimchi also has a mess

of other cool stuff in it, like antibiotic proteins that kill salmonella and

likely

anti-viral substances that are just now being studied.

Good point Heidi Jean. I take them daily too. I have gone a week

or two without them, without seeing any major changes, but I would

imagine it would happen eventually.

Do you make kimchi? I made my first batch lst week. It's gone!

Mmmm..... Am making more tomorrow.

Yeah, I make it! I can't afford the amounts I eat, to buy it. Anyway,

mine is better, if I do say so myself.
