Health Behavior News Service - A scientific, evidence-based Cochrane review has concluded that low glycemic index diets have an edge over other diets for weight loss.健康行为畅言-科学循证Cochrane评价得出结论说,低血糖指数的膳食有优势比其他饲料体重减轻. So forget about the bleached white flour products, and start shopping for foods less likely to spike blood sugar levels if you are a looking for healthy, optimum weight loss.如此忘却漂白白面粉制品,开始选购食品不易穗血糖水平,如果你是一个寻找健康,最佳体重减轻.

“Losing weight is very difficult and many people are unable to sustain a weight-loss diet."减肥是很困难的,很多人都无法维持减重饮食习惯. The low glycemic index diet is satisfying and has proven benefits,” said review co-author Elizabeth Elliott, Ph.D., professor at the University of Sydney, The Children’s Hospital at Westmead, Australia.低血糖指数的饮食是满意的,而且已经证明是有益的,说:"检讨合著伊丽莎白埃利奥特,博士大学教授悉尼儿童医院的电泳,澳大利亚.

The glycemic index (GI) ranks carbohydrate-rich foods based on their effect on blood sugar levels.血糖指数(GI)级碳水化合物丰富的食品基于它们对血糖水平. Compared to high GI foods such as white rice and French fries, low GI foods, such as lentils, sweet potatoes and apples produce more consistent blood glucose levels.相对于高血糖指数的食物,例如白米饭和薯条,是GI低的食物,如扁豆,蕃薯和苹果产生较为一致的血糖水平. Previous studies have indicated that keeping blood sugar levels steady throughout the day may stimulate more weight loss in obese people.以前的研究表明,保持血糖稳定整个一天可以刺激更多的体重肥胖人.

Researchers evaluated randomized controlled trials that compared weight loss in people eating foods low on the glycemic index to weight loss in people on higher GI diets or other types of weight loss plans.研究者评价随机对照试验比较,体重减轻人们食用低血糖指数的重量损人更高不洁饮食或其他类型的减肥计划.

Six trials, involving 202 adults from Australia, France, South Africa, Denmark and the United States were included in the review.六审理中,涉及202名来自澳大利亚,法国,南非,丹麦和美国均在审查之列. The diets lasted from five weeks to six months.日粮历时五个星期至六个月.

The review appears in the latest issue of The Cochrane Library , a publication of The Cochrane Collaboration, an international organization that evaluates medical research .审查出现在最新一期的Cochrane图书馆,发表了Cochrane协作网,一个国际组织,评价医学研究. Systematic reviews draw evidence-based conclusions about medical practice after considering both the content and quality of existing medical trials on a topic.系统审查证据得出的结论,但对于医疗实践后,考虑到双方的内容和质量,现有的医疗测试一个课题.

The review found that participants in weight loss diet plans that focused on eating low GI foods dropped significantly more weight - about 2.2 pounds more - than participants on other diets.审查发现,参加减肥饮食计划,重点放在低进食不洁食物下降更明显体重约220磅,超过与会者对其他饵料. Low GI dieters also experienced greater decreases in body fat measurements and body mass index.低胃肠节食也出现较大跌幅,体脂肪测量及身体质量指数.

“Compared to other diets, the low GI diet is more satisfying - people are less inclined to feel hungry."比起其他营养,低GI饮食更是满足人们都比较倾向于不觉得饿. One advantage of this type of diet is that it is more likely to be maintained than other strict diets on which people feel hungry,” Elliott said.有一个好处,这种饮食习惯是,它更可能是维持比其他严格的饮食对其中的人感到饿了,"埃利奥特说. None of the studies reported adverse effects associated with consuming a low glycemic index diet.轰轰烈烈的研究报道伴有不良反应,进食低血糖指数的饮食习惯.

Low glycemic diets appear to be effective even in obese people who need to lose considerable amounts of weight, the authors said.低血糖饮食似乎都能有效甚至肥胖的人要失去相当数量的重量,作者说. In the two studies that evaluated only obese participants, low GI dieters lost about 9.2 pounds, compared with about 2.2 pounds shed by other dieters.在两项研究仅仅评价肥胖参与者,是GI低节食损失约9.2磅,相比约2.2磅棚等减肥.

Low glycemic index diets might also benefit heart health.低血糖指数的膳食可能也有利于心脏健康.

In the three studies that measured cardiovascular risk factors, people eating low GI foods experienced greater improvements in total blood cholesterol and low-density lipoprotein (LDL) - sometimes called “bad” cholesterol.在这三项研究,测心血管病危险因素,人们食用低不洁食物出现较大改善血总胆固醇和低密度脂蛋白(LDL)-有时被称为"坏"胆固醇. High levels of total cholesterol and LDL cholesterol increase the risks for heart disease.高血清总胆固醇及低密度脂蛋白胆固醇的风险增加心脏病.

After reviewing the findings, Lawrence Cheskin, M.D. said, “There’s surprisingly little in the way of studies to draw any hard and fast conclusions.” Cheskin is director of the Johns Hopkins Weight Management Center and associate professor at Johns Hopkins Bloomberg School of Public Health in Baltimore.经检讨结果,劳伦斯cheskin,医学博士说,"真是出奇的少的方式进行研究,得出任何硬性结论."cheskin主任的霍普金斯体重管理中心副教授约翰霍普金斯彭博公共卫生学院的巴尔的摩. He was not involved with the review.他没有参与审查.

Low glycemic index diets can be effective for weight management, Cheskin said, but the success of low glycemic diets lies with an individual’s willingness to comply with its nutritional principles.低血糖指数的膳食,可以有效控制体重,cheskin说,但成功的低血糖饮食在于个人的意愿,以符合营养原则.

“There aren’t many people who need to lose weight who are willing to eat lots of vegetables and whole grains."不会有太多的人需要减肥的人都愿意吃大量的蔬菜和全谷物. If they did, they wouldn’t have a weight problem in the first place,” Cheskin said.如果这么做,他们不会有体重问题摆在首位,"cheskin说.

Nevertheless, he said, choosing foods low on the glycemic index does have value for overweight or obese people who want to lose weight.不过,他说:选购食品低血糖指数是否具有价值,为超重或肥胖的人要减肥.

“It uses a lot of the generally healthful principles, such as eating lots of vegetables and high fiber and avoiding very energy-dense foods that are high in simple sugars and simple carbohydrates,” Cheskin said.",它是用大量的一般保健原则如吃大量的蔬菜和高纤维和避免能源非常丰富的食物,高糖简单而简单的碳水化合物,"cheskin说.
