I don't know of one alternative doctor who recommend eating fruits under a candidiasis treatment.Pretending the opposite maybe appropriate for a case of very mild candidiasis, but is definitly a quackery when we are talking about of a serious case of chronic candidiasis like mine. Eating one apple would make me feel sick for 2-3 days.
There nothing such one single way to cure the gut and digestive illness. While fruits may help to cure certain types of ailments, they are not appropriate when it comes to a serious case of chronic candidiasis.
