True. There are some dead giveaways. What's been really enightening to me has been the sodium numbers.
yes. But one of the weirdnesses of medicine is the caution about salt intake. Its everywhere 'bad for the heart' (and I do avoid too much, it makes me pee) but I have no idea what science its based upon. After all our blood is 300 mM salt - thats a lot of salt. Indeed, we are basically bags of primordial ocean. Why is it bad for us?
