I’d be curious to know how much salt you actually end up eating. It’s all fine to say no more than 5 grams, but how do you go about working out how much you actually had?
E.g. I cook pasta with heaps of salt in the water, salty like the sea, but the vast majority of the salt goes down the drain when the pasta is strained.
I find the more I eat of sugary or fatty food the more I can handle. My body seems to get used to it. So I’m guessing how people do it is they slowly increase over time without noticing.
Hell, maybe they do feel like shit all the time but don’t associate it with their diet.
