海盐与食用盐营养价值相同 If you've been inside a grocery store in the past couple of years, you've probably noticed the trend in food manufacturers adding "Made with sea salt" to their product packaging. The claim shows up on a wide variety of foods - from organic whole grain pretzels, to mixed nuts, to "American deli cheese product." 在过去几年里，你也许会在杂货店中发现这样一种趋势，越来越多食品加工商在产品包装袋印上了“添加海盐”的标识。从有机全麦椒盐卷到什锦坚果，再到美国熟食奶酪产品。 Clearly the food industry has decided salt from the sea is a major selling point. But why? Is it better for us than plain old table salt? "Sea salt gets a health halo（光环）, and people are using a lot more of it," said Alissa Rumsey, a registered dietitian at NY-Presbyterian/Weill Cornell Medical Center. "The most significant difference is the texture." Sea salts are coarser（粗糙的） and grainier（粒状的） than table salt because the former undergo less processing than the latter, Rumsey said. Sea salts are made from evaporated sea water. Table salt, on the other hand, usually comes from underground salt mines and is processed into finer crystals. (Fun fact: If you're a sea salt fanatic and are confident your local seawaters aren't polluted, you can make your own.) The less-processed aspect of sea salt may be appealing, but both types of salt have the same basic nutritional value, Rumsey said. |
