| | | | This past weekend, a friend and I got to talking about fluoride. As former hippie kids, we both grew up believing that fluoride was suspect. And to this, we have family members who (along with many people around the world) are convinced this naturally occurring chemical does more harm than good. So today, we take the fluoride fears head-on as we try to sort fact from fiction. | | Here's what else we've got in store: | | | | | Stay sharp,

| |  | | | You don't need to be afraid of fluoride | So what is fluoride, anyway? Fluoride is the negative ion of the element fluorine. It's a naturally occurring compound that's found in trace amounts across the natural world.
Why are people upset about fluoride? Ever since the United States started adding low concentrations of fluoride to its water supply in the 1940s, the chemical has been shrouded in controversy. Many people falsely believe that fluoride contributes to conditions including cancer, impaired brain development, and Alzheimer's disease. Some also think that dental health should be up to the individual to manage rather than the state.
Are any of these claims legit? In a word, no. There are decades of peer-reviewed research showing that when used and consumed in appropriate amounts, fluoride doesn't cause health effects. And at concentrations between 0.5–1.0 milligrams (mg) per liter, fluoride has proven benefits, including strengthening teeth and preventing cavities.
Is there anything else we should know? - Don't swallow toothpaste containing fluoride, as it contains a higher concentration than water.
- Prolonged exposure to fluoride can cause fluorosis of bones and teeth. Mild fluorosis is common and may appear as white spots on teeth.
- Fluoride has been found to be toxic at levels over 4 mg per liter, but water with a concentration this high is extremely rare.

| | | | | | | | | An expert weighs in | Q: Is Himalayan sea salt better for you than table salt?
A: It's got some nice flavor, pretty color, and using larger salt crystals like sea salt or Himalayan salt can help you cut down on the actual sodium you use; if you're measuring out a teaspoon, you use less (bigger crystals take up more space than finer salt particles), but it's not magical.

| |  | | | TikTok Takedown: No, you don't need to add salt to your drinking water | | What's the trend this time? People are adding a pinch of sea salt to their water bottles — just enough so that they can't taste it, according to one video. They claim this adds back in important nutrients that have been stripped from our water sources, ultimately helping them hydrate better (and pee less frequently). | | Is there any truth to it? Well, sort of. Sodium is an essential electrolyte and "key for balancing water in your body," according to Healthline's resident registered dietitian Lisa Valente, MS. | | But these TikTokers miss a crucial fact: "Most people are getting plenty of sodium in their diet, often more than what is recommended," says Valente. "So while a small pinch of salt in your water likely won't hurt, most people don't need it to hydrate." | | Will sea salt hydrate you quicker? Actually, no. "There's no difference for hydration between fancy salt and regular salt," says Valente. "There are trace amounts of other minerals and electrolytes in Himalayan sea salt, but not enough to be substantial." | | Remember that your diet can be an important source of water and electrolytes, too. Case in point: these 19 water-rich foods. | | More on hydration: | | | | | | | |
