Okay, I took a look at the article. I am not getting all excited over this for a number of reasons.
1) it's not research on humans in actual clinical situations
2) they are referring to isolated resveratrol, which Buhner does not recommend. He recommends Japanese knotweed, whole herb
3) they are making the same observations about multiple antioxidants that we commonly take - glutathione, Vit C, curcumin, and food with antioxidants
"glutathione, and vitamin C reduce the lethal activity of fluoroquinolones by orders of magnitude"
"Curcumin, which is a common food ingredient in Southeast Asia and is often used medicinally, reduces the lethal activity of ciprofloxacin with cultured bacteria, in macrophage-like cells infected with bacteria, and in a mouse infection model."
"Thus, a cautionary note has been raised concerning antibiotic therapy and consumption of foods having antioxidant activity."
This reminds me of the controversial medical advice that some doctors were following at one time about telling patients not to supplement minerals, even if they were deficient, because it would "feed" the bacteria. Basically, keeping patients in a state of depletion.
Common sense has to be used when evaluating these kinds of studies. Are you going to stop taking glutathione, Vit C, curcumin, and refuse to eat any foods high in antioxidants for fear that the abx won't work?
