Just getting your head around gut health<\/a>? Or sick to your stomach of hearing about it? Either way, we have news. Forget probiotics<\/a> \u2013 the new buzzword in microbiome science is postbiotics.<\/p>\n

Post-what? \u2018Postbiotics are beneficial compounds produced when the good bacteria in our gut break down the fibres and nutrients that feed them,\u2019 explains Rhian Stephenson, nutritional therapist and founder of the nutrition and supplement company ARTAH. Still lost? \u2018Essentially, prebiotics feed probiotics<\/a>, which then create postbiotics as byproducts.\u2019<\/p>\n

So are probiotics just microbiome middle-men \u2013 the halfway point in the process of good gut health, rather than the end goal itself? \u2018In part, yes,\u2019 says Simon Gaisford, professor of pharmaceutics at University College London. \u2018If we were to ask the question \u201cHow do probiotic bacteria have an effect on us?\u201d then there are several potential mechanisms. They could eat (metabolise) harmful or toxic compounds in our guts, they could out-compete or kill harmful bacteria and they could produce useful waste products. The latter are postbiotics \u2013 compounds produced as waste by bacteria living in our gut.\u2019<\/p>\n

Postbiotics, he explains, can include simple compounds, like vitamins or short-chain fatty acids (SCFAs), but also extracellular polysaccharides (EPS) \u2013 in essence, things that help bacteria stick to our gut wall. The term also covers things that might be released when bacteria die \u2013 so the contents of the bacteria themselves (called lysates) and even fragments of bacterial cell wall.<\/p>\n

None of this sounds exactly sexy, so why the hype? \u2018Postbiotics are gaining attention because emerging research links them to reduced risk of chronic diseases, improved gut health, immunity and anti-inflammatory effects, potentially making them even more influential than probiotics or prebiotics alone,\u2019 explains Rhian. <\/p>\n

Take lactic acid for example, says Simon: \u2018This seems to be key in maintaining good gut health (it helps to kill bad bacteria and is also a food source for good bacteria).\u2019 Butyrate – a type of SCFA – is also known to be very beneficial to human health. <\/p>\n

So are postbiotics better than probiotics and can we bypass the latter, justing eat these postbiotic compounds instead? Well, you wouldn\u2019t want to take lactic acid and butyrate off a spoon, says Simon. \u2018Butyrate smells awful and many attempts have been made to turn it into a supplement but without success. I think it\u2019s better to think of \u201ccultivating\u201d a good mix of bacteria in our guts through eating a healthy diet<\/a>, taking a properly formulated probiotic supplement and trying to reduce your stress levels. Then you\u2019ll get the benefits of postbiotics naturally.\u2019<\/p>\n

Rhian agrees, broadly: \u2018Eating prebiotic-rich foods (such as onions, garlic, leeks, asparagus, leafy greens etc) feeds your gut bacteria, which then produce postbiotics naturally during digestion, making prebiotic intake key for optimal postbiotic production. It\u2019s also important to try to avoid foods and habits that could potentially disrupt the microbiome. Excess sugar and alcohol consumption, ultra-processed foods, chemical sweeteners and deep-fried foods, for example, have all been shown to disrupt the microbiome.\u2019 <\/p>\n

There are, however, some potential shortcuts towards postbiotic plenitude, she suggests. \u2018Raw fermented foods, such as kefir, sauerkraut and kimchi, or liquids, such as apple cider vinegar, will likely have postbiotic compounds within them as their fermentation releases metabolites. And while fibre-rich foods don\u2019t have postbiotics in them, eating fibre will boost your postbiotic production.\u2019<\/p>\n
