Healthy Eating
健康饮食
There is much debate nowadays as to what makes up a healthy diet. For example, scientists have insisted for years that a big enemy of health is fatty food.

adj. 脂肪的；多脂肪的
高脂肪食物
However, there is increasing evidence that the real driver of poor health is not so much fatty food, as it is sugar. Heart disease is the number one killer of Americans.

And in America, people who receive 25% of their daily calories or more through sugar are twice as likely to die from heart disease than people who receive less than 10% a day (Journal of the American Medical Association, 2014).
在美国，每天从糖分中摄取25％或更高卡路里的人死于心脏病的可能性是日摄取量少于10％的人的两倍（《美国医学会杂志》，2014年）。

This is true regardless of how healthy the rest of their diet might be. Put more simply, while people continue to argue over whether or not fatty food is dangerous, we already know that sugar is a killer.
无论他们饮食在其他方面多么健康，事实都如此。简单来说，人们还在为高脂肪食物是否有害而争论不休，而我们已经知晓糖分是健康杀手。
