Scientific American: It’s Time to End the War on Salt
This week a meta-analysis of seven studies involving a total of 6,250 subjects in the American Journal of Hypertension found no strong evidence that cutting salt intake reduces the risk for heart attacks, strokes or death in people with normal or high blood pressure. In May European researchers publishing in the Journal of the American Medical Association reported that the less sodium that study subjects excreted in their urine—an excellent measure of prior consumption—the greater their risk was of dying from heart disease. These findings call into question the common wisdom that excess salt is bad for you, but the evidence linking salt to heart disease has always been tenuous.
Well, sort of. ;) Researchers have found that tea companies have been over-touting the health benefits of their tea products (big surprise, I know). Turns out the antioxidants in bottled tea are no where near the amount available in old-fashioned brewed tea.
NPR: “Bottled Tea Comes Up Short In Antioxidant Tests”.
Reseachers [sic] tested bottled teas for antioxidants called polyphenols and found that most brands contain very little of them.
“Out of 49 samples, half of the bottle teas contain less then 10 milligrams of polyphenols,” says Shiming Li, a natural products chemist at WellGen, a company that’s working to develop foods for medical use.
A cup of home-brewed green or black tea has 50-150 milligrams of polyphenols. So you’d have to drink between 5 and 20 of those pint-size bottles of tea to get the same amount of antioxidants. That’s a lot of tea.
So, yeah — take a few minutes and brew your tea. Or let the sun do it, like my wife Denyse has been doing lately.

For some reason known only to the BBC News website gnomes, the story “Guinness good for you – official” is #1 in their lists of most popular stories today. Which wouldn’t be that interesting, except that it’s a story from 2003.
It momentarily confused me as I remembered what I thought was a similar BBC story from a few years ago, linked to here at Celsius1414 in the story “Guinness good for you. And the Pope is Catholic.”, wherein I said:
Since I always feel better after having a pint of Guinness, this seems to confirm my findings.
Indeed. So, turns out it isn’t a similar but the same story, popular again six and a half years later. The salient point being, of course, that Guinness is good for you. Still.
