Yesterday, the Belgium Health Ministry confirmed it was banning fluoride tablets and fluoride chewing gum.(1) This fluoride ban comes after a new health study “found excessive use of fluoride products increased the risk not only of osteoporosis, but of damage to the nervous system too”. Osteoporosis causes weakening of bones and can lead to fractures.
