Their is no way in the world candida overgrowth can do anything or is clinically relevant to anything.

Candidiasis occurs in those who are immunocompromised such as AIDS or cancer patients. Then it is clinically relevant.

It would only be relevant ( to the person not a doctor) if their diet consisted of nothing but soft drinks, donuts and crap food day in day out then yes you've made your own problems right their, but the diet itself would be causing you more harm than any "overgrowth" of yeasts could ever have.

Parasites can be pathogenic and invasive, yeasts are cannot.
