Years ago I’d heard that most nutritionists, if forced to pick a single supplement to take, would choose probiotics. I’ve been an advocate of this supplement for years, and have seen things from clearing up skin issues, to increased immune system function (judged by the lesser sickness seen). I even think they helped someone’s seasonal allergies
What are Probiotics?
The World Health Organization’s 2001 definition of probiotics is
“live micro-organisms which, when administered in adequate amounts, confer a health benefit on the host”.
Oh. Thanks for clarifying.
Our intestines are full of good, and bad, bacteria that help with all kinds of chemical bodily functions. Your gut assists in the digestion and absorption of nutrients. Your gut is the heart of your immune system. Your gut speaks directly to your brain. There’s suggestion that how healthy your gut is might be a huge factor in how happy you are.
Unfortunately, it seems too easy to ruin this incredible system. High acidic diets (lots of protein and sugar) kill off this good bacteria, as do high volumes of antibiotic doses. Trust me, I know how hard it is to change eating habits, but every bit can go a long way.
Reason Behind Increasing Food Allergies Discovered
Thanks to my sister for pointing out this article on how gut bacteria could be the answer for food allergies:

Try to remember grade school. (This may take either a few seconds or hours, depending on how far into the vault those memories are located.) Remember when it came time for lunch. Now, try to remember how many times you heard the phrase “food allergy.”
If you’re in your mid-20s or older, odds are the answer is “rarely, if ever.” But, man, times have changed.
If you have children of your own, or have walked within 100 feet of a school recently, you know that’s not the case anymore. We’re bombarded with warnings about food allergies almost on a daily basis, and that’s because they’re a big problem. They’ve risen a whopping 50% between 1997 and 2007, and no one’s quite sure why. But a new study from the University of Chicago not only offers a possible cure, but a possible cause.
A very quick summary of the study: Scientists took a group of mice with peanut allergies andgave them the gut bacteria Clostridia, a bacteria found commonly in humans. After administering it, they found that the mice no longer had food allergies. Hooray!
To understand more about this study, I called up the lead researcher, immunologist Dr. Cathryn Nagler. She’s spent the past decade studying how our bodies develop food allergies, including trying to analyze why we’re able to eat anything at all.
“All the food that comes into your body is a potentially foreign material,” says Nagler. “I’ve been looking at why we’re not allergic to all of the foods we eat.”
In an attempt to further probe that question, Nagler and her colleagues authored a 2004 study that concluded the removal of gut bacteria in mice led to the development of food allergies. (They removed the bacteria by administering antibiotics, something to keep in mind for later.) With that conclusion out of the way, they began working on reversing the process by re-introducing bacteria. After a few tries, they found one that worked: Clostridia.
“When I say Clostridia, I’m talking about a big class of bacteria,” says Nadler. “It may include hundreds, maybe thousands of members. There’s so much we don’t know about the gut. It’s not like I can say I’d like to test X-Y-Z. You only test what you can isolate. We were lucky because we were able to isolate the Clostridia’s unique property of forming spores.”
Once introduced to the mice, the Clostridia acts as a barrier to keep the allergens in peanut proteins from entering their bloodstream. The allergens are still there, but they’re not able to produce the allergic reaction. Hence: No more food allergies. So, how long until this result provides benefits for humans?
“There’s much, much, much more work to be done,” says Nagler. “Next, we want to look at children with food allergies. And then it has to be developed in a safe drug format, and that’s going to take some time.”
But one thing we don’t have to wait for is what this study suggests about the possible culprit behind food allergies: Our antibiotics-happy culture.
“We don’t want to say this is a cause and effect relationship, but we do want to raise the concern,” says Nagler. “An infectious disease specialist made the point that most kids in the U.S. receive two or three courses of antibiotics in infancy. Most of the treatments they receive are for viral infections, meaning, they’re getting a treatment that serves no purpose.”
What they’re getting instead is the alteration and elimination of the bacteria that may keep allergens at bay. And that’s just one of the problems that are associated with the overuse of antibiotics.
“There’s a lot of reasons to cut back,” says Nagler. “Not only food allergies, but so-called Diseases of Western Lifestyle seem to be increasing with the increasing use of antibiotics. There’s also antibiotic resistance. It’s not controversial to say that we need to be more judicious in our use of antibiotics.”
What results have you seen from taking probiotics?
