i have to add my 2c... i just wanted to say that i've been reading some of the autism boards since getting interested in mercury... and i want to let everyone know how closely some of the problems those autistic kids have relate to things we discuss here.
alot of autistic kids have candida and difficulty in digesting things. many of them do better on a dairy free and Sugar free diet. they all usually have other parasites as well, clostridium, amoebas, you name it. their digestions are messed up. parents see the most remarkable progress in autistic kids when they use certain very high quality digestive enzymes and tons of high-end probiotics. and many give them antifungals as well.... its very interesting, because autism is thought now to be due to the mercury in childhood vaccines - although that's hotly disputed.
i think the "why is candida on the rise at this point in history" is the question. Antibiotics and mercury-laden vaccines came to be used heavily at roughly the same time (i think). and the soils are more depleted today than anytime before.
in the absence of other minerals - more heavy metals will be absorbed. not just mercury either, there's cadmium, lead, etc. these things are potent gland disruptors. could heavy metals be wrecking us?
