> those patients who were hypertensive consumed significantly more salt than those without hypertension

Doesn't that mean there is a causative effect, or are they saying it just a correlation? People with high blood pressure tend to eat more salt? Or if it is not statistically significant, why mention it at all?

The orignal study that caused the salt scare didn't claim that increased salt intake caused increased blood pressure. The claim was that a sodium intake on the high end of regular sodium intake was closely correlated with increased mortality rates in heart attack victims. There was no claim made about sodium intake and blood pressure, nor was there a claim about sodium intake and heart attack rates. This is why I hat…

The entire salt->CVD claim has rested for years upon the assumption that the causal pathway is salt->BP->CVD. The IOM and FDA both talk about this extensively in their recommendations.

The latest health scare is that sitting causes all kinds of trouble. Expect articles in 10 years saying it was all a lie.

Hmm, aren't those warnings about sitting talking about a sort of ridiculous extreme though, sitting in one position for most of the day? You maybe get that on long-distance airplane flights (and even then, you take bathroom trips etc), but even people with desk jobs almost never really sit all day like that....

[And in the of long-distance airplane flights, the whole deep-vein-thrombosis thing does actually seem to be a documented problem, if a pretty rare one...]

Unless causality is clearly articulated, it never should be assumed. Also, it never would be stated if there was not statistically significant data supporting it - keeping in mind this is a Time article and not the original source [0] so you're dependent on the writer knowing what they're talking about as well.

Does the headline square with "patients who were hypertensive consumed significantly more salt than those without hypertension"?

Yes, because correlations don't prove causation. One might want to argue that people who are hypertensive consume more salt as an effect, not a cause. Not to argue that that is proven either, only that it should be on the list of possibilities that merit investigation.

The state of nutrition science is pathetic. The science is conflicted over a simple question of fact -- whether or not a trivially measurable short-term effect occurs when you eat one of the most common food additives in the world. If we can't even answer THIS -- it seems like it should be incredibly easy to answer -- I don't see why people can claim anything at all about diets and macronutrients. Nutrition science n…

Keeping weight low is the primary metric that people currently track and associate with their health, but that doesn't mean weight is the primary problem, just that people think it is.

Fair enough, but the article isn't about weight loss and a lot of research is done on how X food affects the chances of getting Y chronic condition later in life or how to best feed your children so they grow up to their full potential. It's pretty uninteresting to reduce nutrition science to simple dieting.
