So I was reading Cracked article about health risk myths. The first entry was interesting:
[Myth #5] Salt Causes High Blood Pressure
[...] Countless more recent studies have utterly failed to back up the relationship between salt intake and high blood pressure. [...] The truth is that science is still trying to figure out what causes high blood pressure -- maybe it is salt for some people, or just certain types of salt.
I followed the other links there:
- New York Times: We only think we know the truth about salt
- Scientific American: It's Time to End the War on Salt
The links indicate that there isn't a real long-term relationship between salt and high blood pressure. They do support a short-term blood pressure/salt relationship (salt increases blood pressure), but then so does, in the short term, exercise and caffeine.
Is there a reason why salt is labelled as having a long-term negative impact on blood pressure?
