There is a risk if you have an extreme intake, but it's going to be pretty hard to do that by seasoning your food with lite salt unless you're doing something really extreme. Most people have a RDA of at least 2g of potassium, and I would hazard a guess that most people who are being told by their doctors to cut down on sodium intake probably aren't getting a ton of potassium from what they're eating.
Wikipedia quotes an LD50 of 2.6 g/kg in rats, so assuming (big assumption) that the figure is similar for humans, an average 80 kg human would need to consume 208 g of the stuff. Which is probably the whole container's worth.
I'm sure you'd die of other problems from eating that much salt before you die of KCl poisoning.
Also depends on how that LD50 was measured. Oral lethal dose is a lot higher than intravenous.
Fun fact: KCl is used in lethal injections to stop the heart.
Yes, the method of intake is oral. The intravenous lethal dose is irrelevant in this conversation. Nobody is injecting salt in their veins.
Speak for yourself
Some of us like our blood to be seasoned!
If you consider yourself a noodle, I respect that, but this ain't the way to season your pasta water, chief
For men the RDA is 3.4 g
