I seem to remember hearing somewhere that the recommended daily allowance for sodium was a completely made up number. Just an arbitrary figure since no one could say for sure how much or how little sodium may or may not alledgedly cause high blood pressure.
A friend 'who knows' something said that the only people who have a bad effect from salt are those who have a particular sensitivity to salt which can be determined by a 'particular' test.
Few people have the test; most Doctors are not aware of the distinctions. . .
People told to avoid salt because of high blood pressure. But the only ones who need to are those that have the 'particular'. . .somethingorother.
But then 'what do I know'. . .
p.s. I eat lots of salt; and my blood pressure is low; low. . .low. So; figure I do not have at least, that particular whatever. . .
