Whole wheat flour has a lot of oxalate.

White flour has almost none.

So we think, well, how much could this matter?

Well, you're like, oh, beets have it.

Okay, pineapple has it.

And you realize most of the superfoods are high in oxalate.

And when you start eating these things, by the way, I was a vegan, then a raw vegan, so I've had more oxalate than I should have.

Like, oh, I'm totally fine.

And then you start seeing, oh, I have some stuff in my skin.

And then, oh, my joints hurt a little bit.

And for women in particular, you get a lot of urinary tract infections.

And you think, oh, it's a bacterial imbalance.

No, you have razor sharp calcium crystals scratching your urethra.

That's where the bacteria get in.

So you back off on the raspberry juice and the kale juice and the spinach juice and all that stuff.

And magically, you don't get UTIs anymore.

So we don't have to completely eliminate oxalates, but we want to go down to under 200 milligrams a day.

And one green smoothie can have five times the amount your body can process.

And there is at least one case report of a guy who died after 10 days of green smoothies because he was pounding giant spinach smoothies and he gave himself kidney stones and systemic oxalosis.

We knew everything about this before 1950.
