不吃主食會減壽?研究稱可能少活4年,花捲饅頭你們好呀

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.
醫學雜誌《柳葉刀公共衛生》的一項同行評議的研究表明，低碳水化合物和高碳水化合物的飲食會縮短壽命，含有碳水化合物的飲食則可以延長健康的壽命。

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.
該研究分析了參與社區動脈粥樣硬化風險研究的1.54萬名美國中年人的自我報告數據。研究人員將發現的飲食模式與來自20多個國家的43.2萬人的研究進行了比較。

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.
研究人員得出結論，吃適量碳水化合物的人比食用低碳水化合物的人長壽四年，比吃大量碳水化合物的人長壽一年。

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.
低碳水化合物飲食定義爲碳水化合物含量少於食物整體熱量的40%，高碳水化合物飲食則是超過70%。

"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."
“我們的數據表明，在北美和歐洲流行的以動物性蛋白質及脂肪爲基礎的低碳水化合物的飲食，可能與較短的總壽命有關，不應當大肆提倡。”

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.
研究人員發現，食用動物性蛋白質和脂肪來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減壽的風險更高。

"These findings bring together several strands that have been controversial. Too much and too little carbohydrate can be harmful but what counts most is the type of fat, protein, and carbohydrate."
“這些發現把一些有爭議的觀點統一到了一起。過多和過少的碳水化合物都是有害的，但最重要的是脂肪、蛋白質和碳水化合物的種類。”

Self-reported data can be flawed, because it relies on the subject's memory. Another limitation of the study: Diets were measured only twice during the 25-year study period, at the start of the study and again six years later.
自我報告的數據可能存在缺陷，因爲它依賴於受試者的記憶。該研究的另一個侷限性是：在25年的研究期間，飲食只測量了兩次，分別是在研究開始和6年後測量的。
