发表在本月2日在线内科医学年鉴(Annals of Internal Medicine)的一项小型临床研究显示: 对于那些希望降低体重和改善心血管健康的人，减少碳水化合物摄入的效果优胜于低脂饮食。
For people who want to lose weight and boost their heart health
, cutting down on carbohydrates may work better than trimming dietary fat, a new study suggests.

研究的主要作者，来自美国杜兰大学公共卫生学院的的博士后Dr. Tian Hu说：“平均来说，低碳饮食的平均体重下降幅度多出8磅。
"On average, they lost 8 pounds more, and lost more body fat mass," said researcher Dr. Tian Hu, a doctoral fellow at Tulane University School of Public Health in New Orleans.
And while some experts have raised concerns that low-carbohydrate diets could be less than heart-healthy, these findings suggest otherwise, said Dr. Lydia Bazzano, who also worked on the study.
“低碳水化合物饮食历来被看作是潜在的风险，”巴扎诺，在杜兰的一位搞营养学研究的教授这样说。
"Low-carb diets have traditionally been seen as potentially risky," said Bazzano, a professor of nutrition research at Tulane.
Yet in this study, people on the low-carb diet saw slightly greater improvements in their levels of "good" HDL cholesterol and triglycerides -- another type of blood fat. That could have been due to the bigger weight loss, Hu said, or to the greater amounts of "good" unsaturated fat in their diets.
But he also noted that the study ran for just one year, and it's not clear how people on either diet would fare in the long run.

Angelone认为，大众的确摄入过多的碳水化合物了。吃少一点的碳水化合物，增加高质量的蔬菜水果、豆类和全谷物的摄入量可能是更好的选择。
"I do think that most people eat too many carbohydrates," she said. So eating fewer carbohydrates, and choosing high-quality ones -- fruits, vegetables, beans and whole grains -- is a sound idea, according to Angelone.
But one of the concerns with a low-carbohydrate diet, she said, is that people will not get enough fiber. A high-fiber diet can help ward off heart disease, and studies suggest it can aid weight loss by making people feel more full.
So instead of lowering carbohydrates "too much," Angelone said, why not replace refined carbs -- like white bread and pasta -- with fiber-rich foods?
