The current upper limit consider safe to consume with regularity, is "4 milligrams of fluoride per liter of water" The CDC sets the recommend fluorination levels are 0.7 mg/L, more than 4x lower than the amount considered safe to consume. So you would need to consume over 20L of water (think 10 2L soda bottle worth). I couldn't personally physically do that. |
