We consume all sorts of things before really knowing how they’re going to affect us, including probiotics and dietary supplements. But given how preliminary our understanding of our gut bacteria is, it’s very likely that some supplements can work in direct opposition of others. For instance, vitamin A might kill a bacteria hypothesized to promote childhood growth.
Certain food additives may interfere with your gut bacteria, causing changes that boost inflammation in the intestines and potentially promote the development of some chronic diseases, a new study suggests.
Scientists now know that gut microbes almost certainly play a role in us getting fat, and poop transplants are sometimes touted as a potential route to weight loss. But if that’s a little too icky for you, Vanderbilt scientists have been experimenting with more refined microbiome tinkering in mice using genetically modified E. coli.
Many of us, particularly those who prefer to eat our cake and look like we have not done so, have a love-hate relationship with artificial sweeteners. These seemingly magical molecules deliver a dulcet taste without its customary caloric punch. We guzzle enormous quantities of these chemicals, mostly in the form of aspartame, sucralose and saccharin, which are used to enliven the flavor of everything from Diet Coke to toothpaste. Yet there are worries. Many suspect that all this sweetness comes at some hidden cost to our health, although science has only pointed at vague links to problems.
