【medical-news】吃全谷，黑人女性少患糖尿病
Thu Oct 12, 2006 3:39 PM BST
NEW YORK (Reuters Health) - Black women who eat plenty of magnesium-rich foods, especially whole grains, may lower their risk of developing type 2 diabetes, new research shows.
African Americans are more likely to develop type 2 diabetes than whites, Dr. Rob M. van Dam of the Harvard School of Public Health in Boston and colleagues note in their report in Diabetes Care. Some studies suggest, they add, that calcium and magnesium may help lower type 2 diabetes risk, but this research has been done in predominantly white populations.
To investigate whether intake of these minerals might be tied to diabetes risk among black individuals as well, the researchers looked at 41,186 women participating in the Black Women's Health Study. None of them had diabetes at the study's outset, but 1,964 developed type 2 diabetes during eight years of follow-up.
High intakes of magnesium and calcium went hand in hand with healthier habits, such as a more active lifestyle and a lower intake of red meat and saturated fat, the researchers found.
After adjusting for these factors, women who consumed the most magnesium had a 31% lower risk of developing diabetes compared to those with the least amount of magnesium in their diet, the researchers found. However, there was no independent link between calcium intake and diabetes risk.
Eating more whole grains and low-fat dairy foods also reduced the likelihood of developing type 2 diabetes, the researchers found.
Given that the benefits of magnesium may be related to other substances contained in magnesium-rich foods like whole grains, vegetables, cereals, and milk, van Dam and his team add, it's not clear whether taking magnesium supplements would have the same benefits.

全谷物饮食降低黑人妇女得糖尿病的风险
10月12日 星期四 英国夏令时 下午3:39 BST
纽约（路透社健康）最新的研究表明：食用大量富含镁的食物，特别是全谷物，可以降低发生Ⅱ型糖尿病的风险。
波士顿公众健康哈佛大学的Rob M. van Dam博士及其同事在糖尿病护理期刊中报道了：非洲美国人比白种美国人更容易发生Ⅱ型糖尿病。他们补充到：一些研究表明，钙和镁可以帮助降低Ⅱ型糖尿病的发病风险，但该研究主要是在白种人群中完成的。
为了研究黑种人个体食用这些矿物质是否也一样限制得糖尿病的风险，研究人员对41,186名参加黑人妇女健康研究项目的妇女进行了研究。研究开始时没有人患糖尿病，但在8年的随访期间，有1,964人发展为Ⅱ型糖尿病。
研究人员发现：钙和镁的摄入量高与健康的生活习惯紧密相关，如更积极的生活方式和减少红肉、饱和脂肪的摄入量。
调整这些因素后，食用最大量镁的妇女比食用最少量镁的妇女相比，降低了31%发生糖尿病的风险。然而，在钙的摄入和糖尿病的发病风险之间没有独立的联系。
研究人员还发现：吃较多的全谷食物和低脂奶制品也降低了可能发展为Ⅱ型糖尿病的风险。
van Dam和其研究小组还补充说：假定摄入镁的益处可能与富含镁的食物中其它成分有关，象全谷物、蔬菜、谷类食物和牛奶，还不清楚服用镁补充剂是否能起到同样的益处。
