![]() ![]() The placebo effect applies to pro/prebiotics as well as medicines - if people think they’ll work, they’re more likely to report that they feel better.īecause probiotics and prebiotics aren’t subject to the control of drug agencies, they don’t need to go through the same rigorous tests as prescribed medicines. But people say the same about medicines, yet wouldn’t dream of taking them unless they’d gone through proper scientific studies to prove it. Sure, millions of people are convinced probiotics and prebiotics work. But really high-quality evidence is remarkably scarce, not least because the people in the studies are difficult to compare. The fact that worldwide the probiotic/prebiotic market is predicted to be anywhere from $28 billion to $42 billion in the next year tells you everything you need to know about how many people swear by their benefits. Likewise, several studies suggest that people with IBS have an overabundance of bad bacteria, which may not cause acute severe illness like salmonella, but which may bear the blame for their bloating and pain. And with resistant bacteria on the rise, complications from taking antibiotics is an ever-increasing risk. But most of us need antibiotics at some point, despite the average GP’s efforts to keep inappropriate prescribing to a minimum. Prebiotics are resistant to stomach acid and digestive enzymes, so reach the colon unchanged.įor most healthy people, simply increasing the amounts of prebiotic-rich foods, along with a generally balanced diet, should be enough to keep our good bacteria thriving. Foods such as onions, beans, leeks, Jerusalem artichoke and garlic are rich in these non-digestible carbohydrates called prebiotics. We’ve discovered that good bacteria, like Lactobacilli and Bifidobacteria, are more likely to gain the upper hand if they’re 'fed' certain foods. And that means the race is on to discover how we tame our bugs. diff infection? Giving antibiotics which kill off the good bacteria in the gut, allowing the pathogens to thrive.Īn imbalance of gut bacteria has now been placed firmly in the frame as a - if not the main - cause of irritable bowel syndrome, or IBS. diff, which caused 12,681 cases in hospitals in England alone last year. Some bacteria can clearly wreak havoc if they multiply in your gut. ![]()
