Fluoridated water too

I can get non-iodized salt, use a septic tank, not wear shoes, and skip vaccines (and home school) if I so choose to. I can't choose to get unfloridated water from the public system. It's a little odd that a public health intervention has been prescribed to everyone en masse.

Dig a well.

Burger King continued to use iodized salt consistently, while McDonalds, Wendys etc have switched to flakier salts for their fries which cuts total sodium overall by being flatter instead of grainy, but without any iodine added to it. The downward trend in fast food began in the 70s, once sodium was seen as bad, so more salty tasting thin crystals were preferred. [1] - https://pubmed.ncbi.nlm.nih.gov/20634172/ (on re…

> downward trend ... sodium was seen as bad Excess sodium intake is associated with cardiovascular disease and heart failure. Salt is also an opportunistic carrier for iodine supplementation. So to call it good or bad, you'd need to either come up with an epidemiological study of the two diseases relative to each other, or maybe propose an alternative carrier for the iodine supplementation.

The issue with sodium intake is not the quantity but rather the osmolality.

i wonder why when you can simply add potassium salt to make it taste saltier without sodium

> something our bodies can’t synthesize Iodine is an element! As such, it cannot be produced by a chemical reaction and so isn't synthesized in any living organism. It's produced in supernova explosions, by the rapid neutron capture process.

I'd argue that it's not completely unreasonable to claim that stars are living organisms in some sense of this expression

After studying atmospheric Chemistry I found it hard to not feel like our planet was alive in some sense of the word but "alive" has a very precise meaning and Earth doesn't fit the definition. Presumably because it doesn't reproduce

> Excess sodium intake is associated with cardiovascular disease and heart failure. The evidence for this is poor, and there is some evidence to the contrary.[0] Right now it is difficult to assert that there's anything more than a correlation, possibly because many popular high salt food choices could be bad for reasons other than sodium (e.g. fast food staples). In recent decades, widespread success of anti-salt me…

That study is focused on how much to restrict sodium intake in patients who have already experienced heart failure to avoid further clinical events (more heart attacks). The evidence for excess sodium intake causing cardiovascular problems (by way of either high blood pressure or tissue damage from sodium spikes) remains pretty robust. See for example https://pmc.ncbi.nlm.nih.gov/articles/PMC8470268/.

I think the closest thing to what you're saying that has been found is that very low sodium levels in the diet also lead to problems (the body is starved of electrolytes).

Sure. That makes sense physiologically, if you think about membrane potential and hormonal control and kidney capacity. Just like with glucose, it's the spikes that cause the damage. But it's a lot easier to explain to a non-professional that eating overly salty food is bad for them (which is what the advice reduces to in practice) than try to explain osmolality to them.

Why would that be a reason to ban iodized salt?

Even without iodized salt, Japan is one of the highest consumers of iodine worldwide. [1] But I agree. Even though iodized salt is pointless in Japan, so is the law banning it (assuming OP is correct, and it is in fact banned). [1]: https://anaturalhealingcenter.com/documents/Thorne/articles/...

IIUC it's not specifically banned by name in a law, more like not on the whitelist for food additives. Industrialized foodstuffs manufacturing in late 20th century Japan was wild, and additives are managed on approvals basis than bans as the result.

Saltier tasting salt is likely counterproductive, IMO. People aren't born knowing how much salt taste corresponds to how much salt consumption, so that gets tuned by persistent salt deficits causing upregulation of salty food desire. In other words, homeostatic feedback causes salt consumption to stay about the same by increased consumption of salty-tasting processed food.

> In other words, homeostatic feedback causes salt consumption to stay about the same by increased consumption of salty-tasting processed food.

I'd imagine that McDonalds/Wendys/etc don't view that as a bad thing...
