Hello, and welcome to the forum.
I’ve eaten til I was full with the added brown rice, meat
Candida albicans are extremely adaptive; yours appears to have adapted to an environment of “less of everything” as far as the foods that they live on, other than basically rice, which is going a long way in keeping the infestation thriving. Since you don’t have access to a proper probiotic or kefir at the moment, unfortunately, it’ll be necessary to avoid anything at all that will supply the Candida with a food supply; otherwise, they’ll do just what they seem to have done.
The meat is also contributing to a beneficial environment with the production of ammonia when it is broken down in the body. Ammonia is needed by the Candida for existence, in fact, they’re capable of producing it themselves. Adding more than they normally exist on by eating meat products will only make it easier for their continued existence and virulence.
