People who avoid carbohydrates and eat more fat, even saturated fat, lose more body fat and have fewer cardiovascular risks than people who follow the low-fat diet that health authorities have favored for decades, a major new study shows. 一项重大的新研究显示，比起那些遵循卫生部门数十年来一直推崇的低脂饮食的人，不吃碳水化合物但摄入较多脂肪、乃至饱和脂肪的人，消耗的体脂更多，并且罹患心血管疾病的风险更低。 The findings are unlikely to be the final salvo in what has been a long and often contentious debate about what foods are best to eat for weight loss and overall health. The notion that dietary fat is harmful, particularly saturated fat, arose decades ago from comparisons of disease rates among large national populations. 长期以来，关于哪种食物对减重和身体健康最有好处一直存在争议，上述结论不太可能成为定论。几十年前，通过比较全国大量人口的患病率，人们形成了膳食脂肪、尤其是饱和脂肪对人体有害的概念。 But more recent clinical studies in which individuals and their diets were assessed over time have produced a more complex picture. Some have provided strong evidence that people can sharply reduce their heart disease risk by eating fewer carbohydrates and more dietary fat, with the exception of trans fats. The new findings suggest that this strategy more effectively reduces body fat and also lowers overall weight. |
