Please define appropriate levels and then cite some evidence that proves with high certainty that level is safe. For the sake of argument, assume that only 1% of the US has levels that harm IQ. Would it not be worth it to remove fluoride from the water to improve the intelligence of 1% of the population? Especially when you consider we can get fluoride from toothpaste? |
