Probiotics
In a report published in the journal Pediatrics on November 29, 2010, the American Academy of Pediatrics (AAP) reviewed the health benefits associated with the use of probiotics. Probiotics are food stuffs or supplements which contain living microorganisms (bacteria).
As many consumers know, producers of foods and supplements usually go to great lengths to insure that there is no contamination with bacteria in their products. One might ask… “Why would they intentionally add live bacteria to a product meant for consumers?” The answer to this question lies in the fact that not all bacteria are bad.
You might be interested to know that there is a whole host of microorganisms living symbiotically in the intestines of you and your loved ones. Think of them as an army of farmers, soldiers and townsfolk. They take up space and use the resources that you consider waste. They do you no harm. In some cases, they actually help you break down and absorb nutrients that you would not normally have access to. The important part of this analogy is coming up. When bad bacteria (pathogenic bacteria) try to take up residence in your intestines, they have to compete for food and space with these already well established colonies of beneficial bacteria (intestinal microflora). This limits the ability of the pathogenic bacteria to survive and thrive in your intestines. That is a good thing.
So we know that there are good and bad bacteria that like to live in our intestines. The whole point behind the use of probiotics is to maintain and/or repopulate the colonies of intestinal microflora that can become compromised by the use of antibiotics or because they are to some extent flushed out by diarrhea. Antibiotics, the medications prescribed for bacterial infections, can either; kill, weaken or slow the growth of bacteria. By using probiotics you are essentially sending in “fresh troops” to make sure that beneficial bacterial numbers stay high. This leaves less room and resources to be used by the “bad guys”.
As for what the AAP had to say in their review:
They mention that randomized controlled trials (RCTs) have shown that probiotics are modestly effective for the prevention of diarrhea that can be associated with antibiotic treatment.
RCT’s have also shown that giving probiotics to children with diarrhea from sudden onset inflammation of the stomach and intestines due to viral infection can reduce the duration of diarrhea by 1 day.
That there are positive early results from various RCTs showing that probiotics may have a place in the treatment of: inflammation of the stomach due to the bacteria H. pylori, irritable bowel syndrome, chronic ulcerative colitis and infantile colic.
They are not ready to recommend the daily use of probiotics though, and they do warn against their use in children who have long standing or serious diseases.
At this point… You are probably thinking that you might like to know where to get probiotics for the next time your stomach and intestines are troubling you or your child. Well…You can simply go to your local grocery store and get “Activia” the yogurt that Jaime Lee Curtis has been the spokesperson for. You can find many products like it in some dairy food isles. Just look for products that have “live cultures of bacteria”. You can also find probiotics at the local health food store in capsule form. Just ask the person behind the counter. As for the question about how much to take…follow the recommendation of the manufacturer. You can also check with your physician. The AAP doesn’t have the answers for the perfect dose for the perfect amount of time. It just hasn’t been established firmly enough in the scientific literature yet.
