文章是对前几天新闻报道的三篇关于盐的研究(可以加大食盐的摄入量到3--5 g a day)的一些质疑. 感兴趣者可以点击以上链接读全文.
但我在这里只节选他最后面加的这段Bonus question: What kind of salt should we use? (我们应该选用哪种盐?)
健康坛里也讨论过各种盐的好坏. 推荐某些品牌的盐比普通的table salt好, 至少是口味, 还含有其它微量矿物质等等......我们来读一读这位作者的说法:
Bonus question: What kind of salt should we use?
A related question is whether some kinds of salt are healthier than others. Sea salt, table salt, kosher salt, flavored salt, fleur de sel, Hiwa Kai, Black Hawaiian Sea Salt, Kala Namak, “organic salt,” and Pink Himalayan Sea Salt are all basically the same chemical, sodium chloride. Only the trace amounts of other substances vary. Table salt is fortified with iodine and is a highly effective way to prevent iodine deficiency and goiter. Gourmet cooks swear by the taste differences of different salt varieties. Pink Himalayan sea salt was introduced to me by an e-mail correspondent who questioned the claim that it contained “84 trace minerals that promote health and well being.” I questioned it too, so I did a little research.
Mike Adams, the infamous Health Ranger, explains that Himalayan Pink Crystal Salt contains the full complement of minerals and trace elements “just like Mother Earth intended.” It is an unrefined, unprocessed raw salt mined by hand from salt caves that formed 250 million years ago as ocean salt settled into geologic pockets. It is stone-ground, which apparently doesn’t count as “processing.” Table salt is bad stuff, you see, since it was processed to remove all the good stuff and then they had to replace the iodine because people who ate it started to get goiters. Oh, and incidentally he sells the good stuff on his website and even offers a discount.
I found a website that reports the results of a spectral analysis. I think this is where the claim comes from. Even if this analysis is accurate, it is meaningless for health and if anything is worrisome. The amount of minerals in it is too minuscule to make any difference, and we already get plenty of the same trace minerals from other elements of the diet. They claim that two double-blind studies were done, but no such studies are listed in PubMed. There is NO evidence published in peer-reviewed journals that replacing white salt with pink salt makes a shred of difference or leads to any improvement in health.
If you read down the list of minerals, you will notice that it includes a number of radioactive substances like radium, uranium, and polonium. It also includes substances that act as poisons, like thallium. I wouldn’t be worried, since the amounts are so small; but if anyone believes the trace amounts of “good” minerals in Himalayan sea salt are good for you, why would they not believe the trace amounts of poisons and radioactive substances are bad for you?
The claim that pink Himalayan salt contains 84 trace minerals may be true, but the claim that it “promotes health and wellness” is false until proven otherwise by legitimate clinical studies. While waiting for evidence, I’d just as soon my salt didn’t contain uranium.
也有许多美国人关心的几个分类的讨论:
Acupuncture
Chiropractic
Herbs & Supplements
(这个show里提到Supplements只有出事了时FDA才出来亡羊补牢)
