Candida diets are low on bulk. AND, with low gut flora count, you pass food fast, sometimes rather undigested. So I doubt it's diluted much by the time it reaches your intestines...
ALSO, since the fungi you're gunning for LIVE in those same intestines, if it IS diluted to zero effect by the time it reaches that far, then garlic would pretty much be useless.
~~~ In any case, I've stopped garlic entirely and seem to be all the better for it! ~~~
