How do the A-type PACs in cranberries primarily work to support urinary tract health against Escherichia coli (E. coli)?

Answer

By inhibiting the adherence of bacteria to the urinary tract walls

The critical mechanism by which cranberries aid in urinary tract defense centers on the activity of the A-type Proanthocyanidins (PACs). These compounds function by preventing specific types of bacteria, most notably Escherichia coli (E. coli), from adhering or sticking to the epithelial surfaces lining the urinary tract walls. When the bacteria cannot adhere, they are unable to successfully colonize the area. Consequently, the body is able to flush these unattached pathogens out naturally during the normal urination process, thereby preventing the initiation of a full-blown infection. This mechanism positions the cranberry's action as preventative rather than curative for established infections.
