Could you bring some empirics to the table for normal people having a common problem with oxalates at normal doses without predisposing issues like kidney disease or the ones the woman had in the case study?

Does "going easy on oxalates" just mean you have fewer than six spinach smoothies per day?

I'm used to these dietary memes cashing out into either trivial claims or nothing burgers.

> Oxalic acid has an oral LDLo (lowest published lethal dose) of 600 mg/kg.[62] It has been reported that the lethal oral dose is 15 to 30 grams.

and

> Frozen commercially available spinach in New Zealand contains 736.6 ± 20.4 mg/100g wet matter (WM) soluble oxalate

while the USDA says about 900 mg per 100 g for American spinach on average.

So roughly 1% of the wet spinach by weight. 1 kilo of high-oxalate spinach probably has 10 - 20 grams of oxalic acid. That's a lot of spinach, but probably chuggable in one day in smoothie format. Far too close to the LD50 estimate for my comfort!

For one large salad, it's unlikely to exceed a couple grams. I'm unsure about the effects of chronic lower dose exposure.

This is what I mean, though. How many people regurgitating "Be sure to watch out for oxalates!" know that we're talking about thousands of grams of spinach?

Looking it up, people generally eat 50-200mg of oxalates per day with 1000mg being the outlier high end.

Eat your spinach. If you're worried, then cook it.

Well there's the dose that kills you, but there's also the dose that over time gives you kidney stones, if you're prone to that.
