AI Thread Summary
Sodium fluoride is recognized for its dental benefits, particularly in cavity prevention, but it also poses health risks. In large doses, it can lead to serious health issues, including stomach ulcers and potential lethality at 5-10 grams for an average adult. The discussion highlights the dual nature of many substances, emphasizing the principle that toxicity often depends on dosage rather than the substance itself. This concept is illustrated by the fact that even water can be toxic in excessive amounts. The conversation invites opinions on the use of sodium fluoride, balancing its advantages against its risks.

So I just finished my chemistry homework and was going through my answers and googling them to learn more about them. I got to sodium fluoride and I already knew it was that stuff dentists put on your teeth and that it wasn't to good for you. I read that it has some advantages like preventing cavities, but is also used as a stomach poison for insects. I also read that in large doses it can cause stomach ulcers and is lethal at around 5-10 grams for a 150-ish pound human(toxic to inhale too).

So I want to know what your opinions are on the subject, do you agree with the use of sodium fluoride?

This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...

Thread 'Fermentation using mixed legume and grain feedstock'

I use ethanol for cleaning glassware and resin 3D prints. The glassware is sometimes used for food. If possible, I'd prefer to only keep one grade of ethanol on hand. I've made sugar mash, but that is hardly the least expensive feedstock for ethanol. I had given some thought to using wheat flour, and for this I would need a source for amylase enzyme (relevant data, but not the core question). I am now considering animal feed that I have access to for 20 cents per pound. This is a...
