A highlight from What Are Postbiotics?
About nutrition digestion. Immunity metabolism is now being reevaluated. Through the lens of the microbiome who knew that these little critters were so important so first. Let's just sort out. Some of our terms probiotic refers to the bacteria that we might get from foods or supplements that are thought to have beneficial effects in the body the lactobacillus and bifida bacteria that we get from yogurt. For example are some of the more common types of probiotic bacteria pre refers to the food that we consume that provide fuel for the bacteria that inhabit our intestines. And this fuel is mostly in the form of plant fibers from vegetables grains legumes. We humans lack the enzymes to digest these fibers so they arrive more or less intact in the large intestine but unlike us the bacteria living large intestine do have the enzymes to digest these fibers. So eating more of those foods can bolster the health and the vitality of your intestinal population. Symbiotic is another term that you might come across. And this refers to a product that combines probiotic bacteria with pre biotic fibers. Sort of the way. You might buy a product for your lawn that includes both grass seed and plant food to help grow now. Post -biotics is a relatively new term. And it's been coined to the metabolic byproducts of those probiotic bacteria and metabolic byproducts is really sort of a cleaned up way of saying waste products. It just goes to show that one organisms trash is another organisms treasure. These bacteria produce excrete compounds into our digestive tracts. That seemed to be responsible for many of the beneficial effects of probiotics as they go about their cellular business. Bacteria produce among other things hydrogen peroxide. And this might protect us from salmonella and other pathogenic bacteria or yeasts that might just be hanging around the neighborhood for trouble short chain fatty acids are also byproducts bacterial metabolism one of these acidic acid is the substance that gives vinegar its distinctive tang and this may be one of the ways that a healthy microbiome can promote a healthy body weight when you have more beneficial bacteria they produce more acidic acid which helps to regulate your blood sugar and also gives your metabolism a modest boost acids another short chain fatty acid produced by those gut bacteria and it helps promote colon health by providing an energy source for colon cells other post by attic compounds include beta glue certain vitamins various enzymes and even fragments of cell walls that activate the host's immune system.
