1. Get Adequate Iodine.
This is an important element for the normal metabolism of cells, especially thyroid hormones. It will push the fluoride from your body via urine. Some good sources of iodine: cranberries, organic yogurt, potatoes, organic strawberries, and organic navy beans.
2. Add Some Boron.
Boron is a natural element and will help to flush out the fluoride. Some boron-rich foods: most nuts, dates, prunes, honey, broccoli, bananas, avocado. You can also mix 1/32 of a teaspoon in a quart of distilled water and sip it throughout the day.
3. Eat Some Tamarind.
This African fruit and spice is used extensively in Ayurvedic medicine. It can be used in a tincture or tea to cleanse the body of fluoride.
4. Increase Magnesium/Calcium Intake.
You probably already know this, but magnesium is a very important mineral that many are lacking. Besides being so important in the metabolism and synthesis of nutrients within your cells, it also inhibits the absorption of fluoride into your cells. Along with magnesium, calcium seems to help attract fluorides away from bones and teeth, allowing the body to eliminate it.
