Probiotics, prebiotics and gut flora

Taking a probiotic or fermented food can be helpful to our gut flora but only to an extent. They really don’t survive long if they aren’t being fed and the quantity of microbes in the tablets or fermented food compared to the the population in the gut itself…. well, think of it as being a bit like asking one doctor to service an entire hospital. A mere drop in the ocean so to speak!

Probiotics and fermented foods can add new strains (species) but they don’t do a lot to really boost numbers. What really makes a difference is your diet. Within days of changing what you eat, your gut flora changes too, because it’s your diet that boosts or starves each strain. And the healthiest bacterial populations in our gut feed on plant foods (indigestible fibre) so this is what we need in order to nurture and build a thriving healthy gut environment. Animal products don’t contribute to this healthy population because they don’t contain fibre. In fact, by having too much animal foods in your diet, you risk starving your healthy gut flora, and as I’ve pointed out previously, this can lead to inflammation both in the gut and the body as a whole.
