HEALTH EATING
1. 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. However, there is increasing evidence that the real driver of poor health is not so much fatty food, as it is sugar.
当下，何为健康饮食仍众说纷纭。例如，多年来科学家一直认为健康的大敌是高脂肪食物。然而，越来越多的证据表明，导致不良健康的真正因素并非高脂肪食物，而是糖分。
1. 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).
心脏病是美国人的头号杀手。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)。
1. 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.
无论他们饮食的其他方面多么健康，都确实如此。简单地说当人们还在为高脂肪食物是否有害而争论不休时，我们已经知晓糖分是健康杀手。
2. Much of this extra sugar comes from sweets and sweet drinks. The average American gets 1/3 of his or her sugar through sweet drinks alone. The American Heart Association recommends that we limit ourselves to less than 100-150 calories a day from sugar, which is less than what is usually contained in one can of sweet drink or in a single candy bar. In other words, if you want to be healthy, you have to cut down on desserts, and cut out sweet drinks altogether.
多余的糖分大多来自甜食和甜饮料。一个普通的美国人单从甜饮料中摄取的糖分就占三分之一。美国心脏协会建议我们将每日糖摄入量限制在100至150卡路里以下，少于一听甜饮料或一块糖果通常所含的糖分。换言之，要想身体健康，就必须少吃甜点，完全禁饮甜饮料。
3. Beyond this, you can keep healthy by consuming different categories of fresh foods, especially fruit and vegetables, which are full of vitamins and fibre, rather than processed foods. Processed foods often contain less nutrition, and have higher quantities of sugar, salt, and fat than fresh ingredients.
除此以外，为了保持身体健康，你还可以食用不同种类的新鲜食物，尤其是富含维生素和纤维素的水果和蔬菜，而不是加工食品。相比新鲜食材，加工食品通常营养成分较低，糖分、盐分和脂肪含量更高。
