Welcome to the discussion of US Politics!

Rules:

  1. Post only links to articles, Title must fairly describe link contents. If your title differs from the site’s, it should only be to add context or be more descriptive. Do not post entire articles in the body or in the comments.

Links must be to the original source, not an aggregator like Google Amp, MSN, or Yahoo.

Example:

  1. Articles must be relevant to politics. Links must be to quality and original content. Articles should be worth reading. Clickbait, stub articles, and rehosted or stolen content are not allowed. Check your source for Reliability and Bias here.
  2. Be civil, No violations of TOS. It’s OK to say the subject of an article is behaving like a (pejorative, pejorative). It’s NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
  3. No memes, trolling, or low-effort comments. Reposts, misinformation, off-topic, trolling, or offensive. Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
  4. Vote based on comment quality, not agreement. This community aims to foster discussion; please reward people for putting effort into articulating their viewpoint, even if you disagree with it.
  5. No hate speech, slurs, celebrating death, advocating violence, or abusive language. This will result in a ban. Usernames containing racist, or inappropriate slurs will be banned without warning

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

That's all the rules!

Some 'murican cities are unironically trying to get rid of fluoride from water. You know, the thing that also goes in toothpaste and is overall good for keeping teeth healthy

Unfortunately RFK isn't all wrong on this one. Recent evidence is showing it is indeed linked to neurological issues... Furthermore the effects are kind of negated by fluoride in the toothpaste.

The long-awaited report released Wednesday comes from the National Toxicology Program, part of the Department of Health and Human Services. It summarizes [...] that drinking water containing more than 1.5 milligrams of fluoride per liter is consistently associated with lower IQs in kids.

[...]

Since 2015, federal health officials have recommended a fluoridation level of 0.7 milligrams per liter of water, and for five decades before the recommended upper range was 1.2. The World Health Organization has set a safe limit for fluoride in drinking water of 1.5.

These margins are razor thin.

The researchers analyzed 229 mother-child pairs, calculating fluoride exposure from urine samples collected during the third trimester of pregnancy. Most urine samples were collected from fasting women, which improves the accuracy of chemical testing. Children were then assessed at age three using the Preschool Child Behavior Checklist, which uses parent reports to measure a child’s social and emotional functioning.

Children exposed to an additional 0.68 milligrams per liter of fluoride in the womb were 1.83 times more likely to show behavioral problems considered to be clinically significant or borderline clinically significant. Specifically, children exposed to more fluoride had more problems with emotional reactivity, somatic complaints (such as headaches and stomachaches), anxiety and symptoms linked to autism.

No association was found with several other neurobehavioral symptoms, including “externalizing behaviors” such as aggression and attention problems.

Hmm, they are using a statistic as their study and parental reporting… what with PFOAs, pthalates, microplastics and parabens already present in water linked as endocrine disrupters I wonder how that plays over top of all of this fluoride as well.

Meta analysis are not uncommon.

No association was found with several other neurobehavioral symptoms
