No, it doesn't, because sodium ferrocyanide is poorly absorbed in the first place and not bioaccumulative in humans. I suppose you also don't each spinach or almonds either?
"spinach" nope and of almonds not too many either.
But my point is, sodium ferrocyanide intake is not beneficial, (unlike ordinary sodium). Even if it might do no harm, why should I risk even little harm?
And with adding up, well there is a whole libary of other toxic or potentially toxic additives in the normal food you can buy.
I prefer to minimize the potential bad intake, that's all.
If you ate enough salt to reach a toxic dose of sodium ferrocyanide, you’d already be dead from hypernatremia though?
The dose makes the poison.
