發表在本月2日在線內科醫學年鑒(Annals of Internal Medicine)的一項小型臨床研究顯示: 對於那些希望降低體重和改善心血管健康的人，減少碳水化合物攝入的效果優勝於低脂飲食。
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，來自美國杜蘭大學公共衛生學院的的博士後Dr. Tian Hu說：“平均來說，低碳飲食的平均體重下降幅度多出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.
“低碳水化合物飲食曆來被看作是潛在的風險，”巴紮諾，在杜蘭的一位搞營養學研究的教授這樣說。
"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認為，大眾的確攝入過多的碳水化合物了。吃少一點的碳水化合物，增加高質量的蔬菜水果、豆類和全穀物的攝入量可能是更好的選擇。
"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?
