Thx for posting the article. I had someone write me not too long ago about the same thing (who was selling sea salt though). However, the argument in this article seem very overstated to me for reasons I will explain below. First of all, there are more issues with salt than just blood pressure:http://www.peaktestosterone.com/Salt_Deadly
But what I find really strange is that some experts are saying that there are no studies that show blood pressure is not strongly impacted by salt intake. I just think that is crazy advice and all I can say is that I, non-researcher, can find many studies that show such a relationship.
Now I guess you could argue that perhaps salt intake does not impact cardiovascular health as much as anticipated and that athletes may need salt and that some individuals are more salt sensitive than others. Furthermore, salt is one of the electrolytes, so you don't want to go too low.
But, all of that said, many middle-aged and older men battle with high blood pressure and I can't imagine an expert recommending that pounding down all the excess salt in processed and packaged food is going to be good for them! But that seems to be where this guy is headed - or am I missing something?
If you want to lower your high blood pressure, then why not experiment with some reduction in excess salt intake? I don't get it...http://www.biomedcentral.com/1471-2458/6/13/
"There was a significant positive relationship between salt intake and both systolic (2.17 mmHg [95% CI 0.44 to 3.91] per 50 mmol of UNa per day, p < 0.001) and diastolic BP (1.10 mmHg [0.08 to 1.94], p < 0.001) at baseline...In West Africa the lower the salt intake, the lower the BP."
And here is a study on chimps:http://www.nature.com/nm/journal/v1/n10/abs/nm1095-1009.html
"This addition of salt within the human dietetic range caused a highly significant rise in systolic, mean and diastolic blood pressure...The hedonic liking for salt and avid ingestion was apt during human prehistory involving hunter–gatherer–scavenger existence in the interior of continents with a scarcity of salt, but is maladaptive in urban technological life with salt cheap and freely available
"In people aged 50-59 years a reduction in daily sodium intake of 50 mmol (about 3 g of salt), attainable by moderate dietary salt reduction would, after a few weeks, lower systolic blood pressure by an average of 5 mm Hg, and by 7 mm Hg in those with high blood pressure (170 mm Hg); diastolic blood pressure would be lowered by about half as much. It is estimated that such a reduction in salt intake by a whole Western population would reduce the incidence of stroke by 22% and of ischaemic heart disease by 16% [corrected]. "
And I remember a study of the Ornish Diet. His Low Fat Diet reduced blood pressure, but when participants reduced their salt intake, their blood pressure dropped even further.
