Cranberry juice helps against UTI's by alkalinizing the urine. The most common bacteria in UTI's like acidic environments and will multiply more. I dont know how alkalinizing the urine will prevent the toxic effects of AS. If you drink alot of water, anything that is stored in the kidneys will be diluted and pass through faster. I dont see how cranberry juice will help this unless you drink alot of it, in which case it does the same thing as water. Maybe someone else has more info, but thats why cranberry juice is supposedly better for the kidneys and urinary tract infections.
