if you have no candida problem, then it doesn't apply to you.
It is true for some people, (and for some kind of fruit.)
Diferent people have different tolerance to different fruit.
Also, as most fruit today is treated with pesticides and with Antibiotics , it can be a serious health threat for people who already have candida problem.
Most vegetable is OK for people suffering from candida problem, but some people may have problem with carrot juice.
Wheat grass juice helps make carrot juice less candida supporting.
