Hi and welcome back!
Yams are neutral for O nonnies.
I was recently put (back
) on a candida diet for a month by my naturopath. I was told to cut out all processed food, which to my surprise included rice flour and rice pasta/noodles. I was put on oregano supplements and 1 tablespoon of coconut oil per day, even though coconut oil is an avoid. Obviously all refined sugars, molasses, agave etc were also out for the month.
I was allowed dried or fresh fruit like bananas, and starchy food like pumpkin and carrot in moderation, like twice a week only. I guess yams would fall into that category. There was no restriction on allowed citrus fruits.
It worked for me. At my next appointment I was candida-free.
Good luck to you!
