Prebiotic vs probiotic ?

shutterstock_583825927You are taking a probiotic and you think you understand what that does. Now people are talking about prebiotics and you’re not sure whether you should be taking that as well ?

A prebiotic is a food that feeds the  gut bacteria whereas a probiotic is a  combination of strains of various gut bacteria. Different types of prebiotics can feed different strains of bacteria so the prebiotic can be used therapeutically to promote beneficial strains at the expense of more problematic strains.

Lots of different foods are prebiotics as well as various supplements. For an appropriate  list  of foods look at my most recent blog Feed your Good Gut Bacteria . In terms of prebiotic supplements there are a number of interesting options to consider.

  1. Hydrolysed Guar Gum is a partially broken down soluble fiber which is extracted from the Indian Cluster bean.
  2. Galacto-oligodisaccharidases (GOS) are made from either a milk product source or from chicory roots.  It is helpful if someone is also constipated and may increase bifidobacteria as well.
  3. Larch is the bark of a tree. It supports the production of a key fuel to support the integrity of the gut lining known as butyrate. It also has been shown to support the growth of good gut bacteria such as Bifidobacteria and Lactobacillus which reducing the growth of E Coli and Clostridia. It is thought that the larch stimulates the immune system and therefore keeps opportunistic bugs in check.
  4. Lactulose is made of up of two sugars galactose and fructose and is used to treat constipation. It is not digested like other sugars and therefore when it moves through to the colon the bacteria can feed on it and it draws water into the stool making it easier to pass.

Once you know the composition of your gut flora you can really assist in building better diversity by supporting the growth of beneficial strains or by crowding out problem bacteria. Ideally using testing such as a Comprehensive Digestive Stool Analysis or directly through a group like Ubiome you can improve your knowledge of your gut bacteria.

Do you have the right bugs in your gut?

Bacteria

Does everyone you know seem to have a food intolerance, allergy or asthma?  Why is this so much more common than  20 years ago? I remember at school only one child having an asthma puffer but now it seems that schools need to keep a spare in the first aid kit as so many children have asthma.

One of the reasons there are so many allergies is that our “microbiome” or the bacteria in our intestine has changed a lot due to the food we are eating. Candida for example thrives on sugar and the highly refined diet that many people eat feeds it beautifully. Not only does it feed it but candida is smart and basically causes you to crave sugar as well making it harder to treat.

Some recent research on rats found that a common bacteria, E. coli , increased inflammation to gluten (the protein in wheat, barley and rye) , prompting what’s sometimes called a “leaky gut”. However a beneficial bacteria called bifidobacteria protected the intestinal barrier.  Your gut bacteria may influence the immune response to gluten.  How many other intolerances to food are being created by the balance of “good” and “bad” bacteria ? Certainly significant research is being directed at understanding the roles of these bacteria and how they can support your health or undermine it.

An easy way to support good gut health is to include small amounts of fermented food or drinks in your diet. Ideally you need a range of good bacteria as they all seem to have different functions.

Traditional diets always included a form of fermented food to support good gut health as well as ensuring you could extract the maximum in nutrients from your food.  Have a look at keffir, kombucha and other forms of ferments with vegetables such as sauerkraut and kim chi.  Sites such as Pinkfarm and Kitsa’s kitchen on facebook have lots of information about how you can easily incorporate these foods into your diet.
