One theory behind yeast infections is that when the organs are not functioning properly, the whole body is thrown out of wack and opportunistic things such as yeast take advantage of this and begin to migrate to the blood stream and rapidly colonize. Yeast is found in small amounts in the GI tract and when the body is in a balanced state, the good bacteria(acidipholis) keep the yeast in check. Your diet may be the best in the world, but use of Antibiotics , execessive life stress, etc., can throw your body out of whack. Keep in mind that once you get a yeast infection, you will only feed it and cause it to rapidly replicate by consuming any form of sugar, even Sugar from fruits.

The solution: Adopt a Anti-Candida Diet to starve the yeast http://pages.britishlibrary.net/lobster/candida/diet.html Ingest a lot of Sugar free yogurt or kefir(if you are allergic or sensitive to dairy). At the same time, focus on rebalancing the PH of your body as described by Moreorless.

Go on a assertive program of liver flushes, kidney flushes, and Colon Cleanses to bring your organs back to peak efficiency.

"Temporarily" consider taking proven anti-Candida supplements such as oil of oregano, carpylic acid, grapefruit seed extract, etc., to quickly kill of the yeast. By the way, if you don't want to spent a lot on supplements, at least consider ingesting Virgin Coconut Oil, which is know to kill the yeast due to its high carpylic acid content.

If you take an integrated approach to the problem of yeast, you will be more successful in eradicating the problem and preventing its recurrence. Also keep in mind that you may temporarily push your body to a more acidic state by consuming such things as Carpylic acid, so it is all the more important to focus on rebalancing you body back to a balanced PH state once you have eradicated the yeast.

Best Wishes.
