“Many yoghurts are loaded with live bacteria, and labelled with claims that consuming these microorganisms can be good for your health. But a study published today shows that such yoghurts have only subtle effects on the bacteria already in the gut and do not replace them.”
Yes, but the paper goes to point out that both in humans and mice, there was an upregulation of polysaccharide metabolism genes in the existing gut microbes. Hm, there are some serious implications there.
We tend to think when we hear the word” bacteria” that it is always dangerous or bad, when in actuality our intestinal tracts contain a complex and diverse culture of disease causing (bad) and “friendly”or good bacteria. We must have the “friendly” bacteria to survive.
