Probiotics



Probiotics.  I think we have all heard of them.  And many mainstream yogurts have live active cultures, which are probiotics.  For years the mainstream pediatric medical community has accepted them as helpful, especially with antibiotic treatment or diarrhea illness.  But what does live active cultures mean?  And which bacteria are in yogurt?  What bacteria are prescribed? And are these the same as the over-the-counter supplements?  Should you take supplements or eat foods with live active cultures in them? And how young can you start feeding kids probiotics?  What are other people doing and trying?  And does this ever cause people to get sick?  Is acidophilus enough or should you be taking more than one kind? How often?  Why?  How long have people been using probiotics?
As I previously mentioned, when I started writing the probiotic post I thought it would be fast and easy.  Now it is going to take more than one post and more research than I have already completed.  In fact, I discovered a textbook called Probiotics: A Clinical Guide that I seriously want to get my hands on.  But, the general idea is that probiotics can be helpful for certain conditions.  And this is what I have found so far on specific types of illnesses and which probiotics are helpful.  If you are looking for supplements you should be able to check the label to see if it contains the ones you are looking for.  Next week I’ll talk more about foods that include these helpful organisms.  My lacto-fermented salsa is not ready yet, so no news on that front.   Although, my dear husband did ask why we were waiting to eat it and I told him about lacto-fermentation. 
Diarrhea
 I believe that to date probiotic treatment of diarrhea is the area of probiotics that has been most studied and used.  The most effective probiotic treatment for antibiotic associated diarrhea (AAD) is Saccharomyces boulardii in combination with Lactobacillus rhamnosus and Bifidobacterium.  For AAD, the recommendation is that probiotics should be started with the antibiotic and continued for 30 days. 
Atopic Disease (allergies)
Probiotics have also been shown effective for atopic diseases such as allergic runny nose, eczema, and asthma in adults and children. For allergic problems like these a combination of  L. bulgaricus, L. paracasei, Streptococcus thermophiles and  L. rhamnosus have been shown in the research to be helpful.  It is also recommended that GOS/beta-1,3-glucan prebiotics be given with the probiotic.  We talked about GOS prebiotics when we talked about fiber.  Beta-1,3-glucan is also food for good bacteria.  It is found naturally in the cell wall of yeast, the bran of grains like oats, barley, and certain mushrooms like shitake and reishi. Just in case you were wondering, it is the beta glucan in oats that is thought to reduce cholesterol.
More
Some other conditions that research has shown probiotics to be helpful with are irritable bowel syndrome, inflammatory bowel disease, vaginal yeast infections.  Scientists have only just begun to study synbiotics (probiotics and prebiotics) and different diseases, so expect more information to come out all the time.  For instance, they are studying synbiotics and other immune system caused illnesses such as multiple sclerosis and diabetes.

There is so much more to tell you about probiotics, so look for another post next week.

More on fiber and oligosaccharides



Our bodies are very complicated.  The more I study it, the more I am completely convinced that only God could have created as marvelous a thing as the human body.  But, I am also realizing that we should treat our body as an ecosystem.  When we think about having more good bacteria than bad bacteria in our colons in order to have a healthy GI system and immune system and feeding these bacteria fiber so they can thrive like we did yesterday in the fiber post, it become clear how much our body is more like an ecosystem than a single organism. 

But, if your family is like my family, increasing fiber can be a complicated task.   The short list of fiber foods are things you may already know: whole grains, beans, vegetables, fruits, seeds and nuts.  So where do you start?  I’ll tell you where I am NOT going to start, and that is whole grains.  I haven’t quite figured out what I think about grains, whole or otherwise, soaking or not soaking, etc etc.  That doesn’t mean that I am not eating grains.  It just means that for now I am not really going to worry about increasing my intake or my kids intake.  I will say that most of the sandwich bread that I buy is whole wheat because it is much easier to find without high fructose corn syrup.  But, so far, what I am making at home is with plain old all purpose white flour. Gasp. I know, I told you I have to think more about all the issues related to flour and grains in general.

Here are the things that my kids eat that are especially high in fiber:
Corn ½ Cup = 5 g fiber
Popcorn ½ Cup = 1.7g fiber
Apples 1 med = 4.4g fiber
Berries (especially raspberries) ½ Cup raspberries = 4g fiber; 1 C cup strawberries= 3.3g fiber
Kiwis 1 large = 2.3g fiber
Peanuts and Cashews 1/4cup 1-3g fiber
Broccoli 1Cup = 5g
Cabbage (if its cole slaw) 1/2Cup slaw = 1g fiber
Brussels Sprouts (only if they are cooked the right way) 10 sprouts have 7g of fiber
Avocado 1= 9g of fiber
Oatmeal ¼ Cup= 4-5g fiber
Raisins ½ Cup – 4g fiber
Carrots 1 = 2g fiber
Here are the high fiber foods that I want to get them to eat, eat more, or try:
Beans and Lentils black beans and kidney beans 1/2Cup= 9.7g fiber lentils = 7.5g fiber
Chia Seeds 1 tablespoon = 5.5g fiber

Basically, the older my kid, the more variety of fiber foods she eats.  So I am going to make sure that we have these foods around a lot and gradually increase the amounts and varieties that we all eat.  My little ones always want to eat what the rest of us are eating.  And yes, I mean the baby too.  Baby loves his broccoli and carrots.   Of course, we aren’t trying berries and nuts just yet. 

But, we learned yesterday that fiber is really necessary to keep the bacteria fed and the bile clean.  So did baby only just now get fiber?  I mean, milk doesn’t have fiber, does it?

Now, I’m going to get a little heavy.  There is this thing, called oligosaccharides.  They are carbohydrates that consist of a relatively small number of monosaccharides, or simple sugars.  So, they are sort of between sugars (monosaccharides) and staches (polysaccharides) and lately we have heard them called prebiotics.  They are made by plants and are not digestible by humans, which makes them technically a fiber.  And they are food for the good bacteria in your large intestine.  There are several types of oligosaccharides: fructo-oligosaccharides (FOS), galactooligosaccharides (GOS), mannan oligosaccharides (MOS), and HMOs.  You can take GOS supplements.  They are quite popular in Japan.  And a study has shown them to decrease influenza infection.  You can get them naturally by eating chicory root, Jerusalem artichokes, onions, leeks, garlic, legumes, wheat, and asparagus.  My understanding right now, is that when you soak or ferment foods before eating them some of the oligosaccharide is used up.  I’m not sure if that decreases the beneficial effects in the intestines or not.

So, back to whether or not baby got any fiber in breastmilk.  The answer is an amazing “YES”.  In fact, breastmilk has Human Milk Oligosaccharides (HMOs).  These are the HMOs listed above.  According to Engfer,Stahl, and Finke et al “ a majority of HMOs reach the large intestine, where they serve as substrates for bacterial metabolism. Therefore, HMOs might be considered the soluble fiber fraction of human milk.”
I think that is enough for today.
