Studies show that fluoride has a negative effect on Ca²⁺ATPase in the brain and kidneys. It is even used in laboratory studies as a Ca²⁺ATPase inhibitor.
Find out if the water in your area is fluorinated.
If it is, consider a reverse osmosis water filter installed in the kitchen — charcoal filters do not remove fluoride.
Practice responsible use of dental products.
Dentists now recommend children only use a pea size amount of toothpaste.
Keep toothpaste out of reach of children.
Avoid candy-flavored or inappropriately marketed toothpaste.
Be cautious about using fluoridated toothpaste in children younger than age six.
Avoid fluoride mouthwashes entirely for children.
Avoid processed beverages and foods.
In the U.S., studies have shown that sodas, juices, sports drinks, beers, and many other processed foods, including infant foods, now have elevated fluoride levels which have come from the water used to process the foods and drinks.
Due to its toxicity, fluoride is used in some pesticides to kill insects and other pests. As a result, some food products—particularly grape products, dried fruit, dried beans, cocoa powder, and walnuts—have high levels of fluoride.
Reduce intake of foods made with mechanically separated meat (chicken fingers, nuggets, etc.), especially for young children.
These products contain elevated levels of fluoride due to the contamination from bone particles that occurs during the mechanical deboning process.
For adults a non-fluoride toothpaste is an option.
Check out the Environmental Working Group’s toothpaste database for numerous chemical-free options.
