摘要
Somdat Mahabir of the National Cancer Institute and his colleaguesinvestigated the role of alcohol on serum vitamin D values among post-menopausal women. Although alcoholics tend to have weak bones, some data had indicated that moderate alcohol consumption might improve bone mineral density. The question Mahabir's group sought to answer: Would a drink or two a day compromise bone health？ So they recruited 51 postmenopausal women to a long trial. For eight weeks, each got no alcohol （in orange juice）, the equivalent of one drink's worth, or two drink's worth of alcohol. Each woman went through each eight week cycle, although in a random order （with four weeks of fin between each cycle）. During the test phases, all meals were prepared for the women —— ensuring that each received all the nutrients needed to support health and maintain their current weight. Bottom line: This federal study found no link between alcohol and D. Only two things stuck out: Blacks tended to have about two-thirds as much vitamin D in their blood as did white women （a trend noted elsewhere）.And the more obese a woman was, the lower her vitamin D level. Some studies have indicated that anything under 80 nanomoles of vitamin Dper milliliter of blood should be deemed insufficient. In this new NCl trial,lean women tended to average about 60 nm/ml, overweight women had around 55 nm/ml, and those who were obese averaged only about half the desired level —— i.e. roughly 40 nm/ml. The good news: A year-long Jenny Craig-sponsored study of weight loss in roughly 400 women in their mid-40s found that as these ladies shed the pounds, their vitamin D values climbed. Which was a good thing since their starting （and, unfortunately, ending） vitamin D levels would qualify them as deficient. ……
