If you've seen a news article going around linking a correlation between fluoridation in water and ADHD, you're not alone.
It was all over twitter today and I expect I will see it all over the rest of social media in the days and weeks to come.
But don't get all freaked out worrying about the water your kids are drinking. Most of us drink bottled spring water anyway these days.
My whole family has generations of ADHD and we all grew up on natural spring water and well water with no flouride.
Thought the numbers the scientists looked at over the 6 years showed an increase in amounts of fluoride in the water, and noted an increase in ADHD in the same areas over those 6 years-The scientists were quick to point out that this is just one study, and doesn’t prove that there is necessarily a causal link between fluoridation and ADHD.
They also stated a number of important limitations in the study, stating that individual fluoride exposures we NOT measured,and ADHD diagnoses of the people in those areas we not independently verified.
In other words, they looked at an area in the USA that had fluoride amounts increasingly added into the tap water over 6 years and then looked at the number of people in the same area of the same time period who said they were diagnosed with ADHD.
That would be like me doing a study to find a correlation between people who bought and use tablet computers ( that have only been out and mega popular for personal use for about the last 5 years) and then asking only those people how many of those people were diagnosed with ADHD in that time. And, then concluding that tablet use caused ADHD, somehow.
CORRELATION DOES NOT EQUAL CAUSATION
Diagnosis in the last 6 years of ADHD ANYWHERE has increased for the simple reason that ADHD is more understood among the general population AND among doctors in general recognizing it as a legitimate learning disability among children. Not to mention the fact that adults are now being properly diagnosed late in life because it was dismissed in them as children as bad behaviour and being lazy.
There can be a correlation between ANY two things if you look long enough.
Charles Poole, an epidemiologist at the University of North Carolina, said of this research, that fluoride should be more carefully studied, but doesn’t show much of anything by itself.
“I think the authors (of this study) were quite cautious in their interpretation… and [accurate] in their statement of the study’s limitations,” he says. “So it would be ludicrous to draw a strong conclusion based on this study alone.”
