Low-carb diet linked to early death
    2019-01-03  08:53    Shenzhen Daily

不吃主食会减寿?

Cutting carbohydrates might also cut lifespan by up to four years, according to a medical study published in August.

The peer-reviewed research published in the medical journal The Lancet Public Health suggests low and high-carb diets could shorten life, and diets including some carbs could promote a healthy lifespan.

Scott Solomon, senior author on the study, called the research “the most comprehensive study of carbohydrate intake” ever.

The study analyzed self-reported data from more than 15,400 middle-aged Americans who participated in the Atherosclerosis Risk in Communities Study. The dietary patterns researchers found were compared against additional studies that included 432,000 people in more than 20 countries.

Researchers concluded that people who ate a moderate amount of carbohydrates lived four years longer than those with low-carbohydrate consumption and one year longer than those who ate a lot of carbohydrates.

Low-carb diets were defined as less than 40 percent of calories from carbohydrates and high-carb diets were more than 70 percent of calories.

“Our data suggests that animal-based low carbohydrate diets, which are prevalent in North America and Europe, might be associated with shorter overall life span and should be discouraged,” lead author Sara Seidelmann, fellow at Brigham and Women’s Hospital in Boston, said in a statement.

Researchers observed that people who replaced carbohydrates with protein and fat from animals had a higher risk of early death compared to those who replaced carbohydrates with plant-based foods.

“These findings bring together several strands that have been controversial,” co-author Walter Willett at Harvard T. H. Chan School of Public Health said in a statement. “Too much and too little carbohydrate can be harmful but what counts most is the type of fat, protein, and carbohydrate.”

It’s important to note that this study observes a correlation between low-carb diets and death risks but not a cause-and-effect relationship. Self-reported data can be flawed as well, because it relies on the subject’s memory.

八月发表的一项医学研究称,低碳水化合物饮食会缩短预期寿命,长达4年。

医学杂志《柳叶刀公共卫生》的一项同行评议的研究表明,低碳水化合物和高碳水化合物的饮食会缩短寿命,含有适量碳水化合物的饮食则可以延长健康寿命。

这项研究的资深作者司各特•所罗门称这项研究是“有史以来对碳水化合物摄入量最全面的研究”。

该研究分析了参与社区动脉粥样硬化风险研究的1.54万名美国中年人的自我报告数据。研究人员将发现的饮食模式与来自20多个国家的43.2万人的其它研究进行了比较。

研究称,吃适量碳水化合物的人比食用低碳水化合物的人长寿四年,比吃大量碳水化合物的人长寿一年。

低碳水化合物饮食定义为碳水化合物含量少于食物整体热量的40%,高碳水化合物饮食则是超过70%。

这项研究的主要作者、波士顿的布里格姆妇女医院的研究员莎拉•赛德曼在声明中称:“我们的数据表明,在北美和欧洲流行的以动物性蛋白质及脂肪为基础的低碳水化合物的饮食,可能与较短的寿命有关,不应大肆提倡。”

研究人员发现,食用动物性蛋白质和脂肪来代替碳水化合物的人,比那些用植物性食物代替碳水化合物的人减寿的风险更高。

该研究的合著者、来自哈佛陈曾熙公共卫生学院的华特•威利说:“这些发现把一些有争议的观点统一到了一起。过多和过少的碳水化合物都是有害的,但最重要的是脂肪、蛋白质和碳水化合物的种类。”

必须注意的是调查结果只是显示观察性关联而不是因果关联。同时自我报告的数据可能存在缺陷,因为它依赖于受试者的记忆。
