Bread and potatoes feed candida. Mercury does also cause cognitive problems. Magnesium deficiency is linked to cognitive problems, So make sure to take magnesium citrate(or other highly absorbable form) with at least 400 mg a day of magnesium. Calcium supplementation is also important.So are B vitamins. Vitamin D is also very important. Some experts are now suggesting that those who don't get plenty of sunlight should take 2,000 IU a day of vitamin D(or perhaps more depending on how their blood levels are). Since I am not having my levels checked, I will stick with 2,000 IU a day of supplements.

For those with candida overgrowth, the main problem is the acetylaldehyde that the candida produces. It is what alcohol is metabolized into in your body, so if you feel like you have a hangover all the time and never drink, you probably have a candida problem. This link discusses acetyladehyde. I listed it earlier in this thread, however you didn't comment on it.

Detoxifying your liver is also part of the solution. There are some commercially available detox teas, or you could use licorice root tea, dandelion, and milk thistle extract. are you overweight? I was very overweight for a long time and I believe my body was retaining plenty of water, and my thyroid and adrenals weren't functioning properly. Now I am close to ideal weight, but still am ill. At least I feel I am making some progress. With this illness, one often has to feel worse for a while before feeling better. This may involve killing candida, or releasing mercury stored deeply in the body, which can cause worse symptoms as the the mercury is brought into the bloodstream before being released.

I have been drinking Yogi Egyptian Licorice tea 2 or 3 times a day. I think this helps me feel better. It has licorice root, cinnamon, orange peel, ginger, cardamom, and black pepper. These are all antifungal. If you can't get this, then you might want to try some other licorice root tea. I am also drinking plenty of chamomile and peppermint teas.
