Mercury is very toxic to most bacteria, and if its in your intestines (it will come out naturally in your bile and get into your intestines) it will alter the bacteria that can live there. There are few organisms that can thrive in the presence of high concentrations of mercury, and most of them are yeast, candida albicans being one of them.

So what I believe is the trick to getting rid of mercury is reducing what yeast feed on which is sugars, and getting extra amounts of good bacteria so hopefully some of them survive the onslaught of mercury. I do this by eating plenty of homemade sauerkraut and kim-chi, which contain a lot of natural beneficial bacteria and I also make yogurt and kefir out of fresh raw milk. Kefir is great because it has beneficial yeast which can help overtake bad yeasts. I keep my carbs low but I have to eat some or I will get liquid stools very very easily.
