Real quick let me put on my tin foil hat before we get into this study.
Okay, I'm good to go.
Here's what we're looking at:
This is a US government report from the National Toxicology Program, just so you don't think I'm some sort of conspiracy theorist or anything.
Let's dive right in. Here's what the study found.
The NTP monograph concluded that higher levels of fluoride exposure, such as drinking water containing more than 1.5 milligrams of fluoride per liter, are associated with lower IQ in children. The NTP review was designed to evaluate total fluoride exposure from all sources and was not designed to evaluate the health effects of fluoridated drinking water alone. It is important to note, however, that there were insufficient data to determine if the low fluoride level of 0.7 mg/L currently recommended for U.S. community water supplies has a negative effect on children's IQ.
Bro, you used to be called a conspiracy theorist for statements like that!!
The NTP uses 4 confidence levels - high, moderate, low, or very low - to characterize the strength of scientific evidence that associates a particular health outcome with an exposure. After evaluating studies published through October 2023, the NTP Monograph concluded there is moderate confidence in the scientific evidence that showed an association between higher levels of fluoride and lower IQ in children.
The determination about lower IQs in children was based primarily on epidemiology studies in non-U.S. countries such as Canada, China, India, Iran, Pakistan, and Mexico where some pregnant women, infants, and children received total fluoride exposure amounts higher than 1.5 mg fluoride/L of drinking water. The U.S. Public Health Service currently recommends 0.7 mg/L, and the World Health Organization has set a safe limit for fluoride in drinking water of 1.5 mg/L.
Boy, this tin foil hat is starting to make my brain hurt.
Since 1945, the use of fluoride has been a successful public health initiative for reducing dental cavities and improving general oral health of adults and children. There is a concern, however, that some pregnant women and children may be getting more fluoride than they need because they now get fluoride from many sources including treated public water, water-added foods and beverages, teas, toothpaste, floss, and mouthwash, and the combined total intake of fluoride may exceed safe amounts.
And even without those extra forms of fluoride:
The report said that about 0.6% of the U.S. population — about 1.9 million people — are on water systems with naturally occurring fluoride levels of 1.5 milligrams or higher.
Essentially, we've gone and added fluoride to our drinking water so we get fewer cavities (Grand Rapids, MI, was the first to do this in 1945). Our government endorsed this idea in 1950, just before fluoride started being added to toothpaste.
And now, here we are in 2024 and we're being told that too much fluoride can lower IQ in children, and that nearly 2 million Americans are on water systems which carry too much fluoride.
Okay, then.
