A naturally occurring chemical in turmeric, curcumin, has recently been found to lessen the neurotoxic effects of fluoride. In a laboratory study using mice, it was found to have a significant effect in preventing fluoride-induced neurodegeneration (brain damage). A study a few years ago also found that curcumin is effective in stimulating the growth of new brain cells, so it looks like turmeric is something quite beneficial to your brain.
