现在关于健康饮食的构成有很多争论。然而，越来越多的证据表明，不健康的真正杀手是糖。因此，如果你想保持健康，你就必须少吃甜点，并完全戒掉甜饮料。除此之外，你还可以通过食用不同种类的新鲜食物来保持健康。最后，健康饮食的一个基本关键是吃得慢。细嚼慢咽不仅能让你更好地消化食物，还能让你更享受食物。最重要的是，健康饮食没有诀窍。健康饮食始于对食物有一个健康的态度。
Summarize and retell
There is much debate nowadays as to what makes up a healthy diet. However, there is increasing evidence that the real killer of poor health is sugar. Therefore, if you want to be healthy, you have to cut down on desserts, and cut out sweet drinks altogether. Beyond this, you can keep healthy by consuming different categories of fresh foods. Finally, a fundamental key to healthy eating is to eat slowly. Eating slowly not only allows you to digest your food better, but also allow you to enjoy your food more. Above all, there is no one trick to healthy eating. Healthy eating starts with having a healthy attitude towards food.
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. Heart disease is the number one killer of Americans.
Language points
Analyze and translate the difficult and long sentences.
如今对于（什么样的饮食才算健康）存在着诸多争论。
例如，科学家们多年来一直坚持认为（高脂肪食物是健康的大敌）。
然而，越来越多的证据表明，健康状况不佳的真正原因并不是高脂肪食物。
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).
This is true regardless of （how healthy the rest of their
diet might be）.
在美国，（每天从糖中摄取25%或更多卡路里的人）死于心脏病的可能性是（那些每天从糖中摄取不到10%热量的人）的两倍。
不管他们的其他饮食有多健康，这都是事实。
Put more simply, while people continue to argue over （whether or not fatty food is dangerous）, we already know （that sugar is a killer）.
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.
更简单地说，当人们继续争论（高脂肪食物是否危险）时，我们已经知道（糖是杀手）。
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.
美国心脏协会建议（我们每天从糖中摄取的热量不超过100-150卡路里），（这比通常一罐甜饮料或一块糖果所含的热量要少）。
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.
除此之外，你还可以通过食用不同种类的新鲜食物来保持健康，尤其是水果和蔬菜，（它们富含维生素和纤维，而不是加工食品）。
Besides this, it is also important to have some meat, beans, or dairy products in your diet, as they provide the necessary protein for strong bones and muscle growth.
As with everything in life, moderation is key. The ideal diet is a balanced one, without too much or too little of any one thing.
除此之外，在你的饮食中加入一些肉类、豆类或乳制品也很重要，因为它们为强壮的骨骼和肌肉的生长提供了必要的蛋白质。
Finally, a fundamental key to healthy eating is to eat slowly. It takes about twenty minutes from the time you start eating for your brain to tell your body (that you are full).
(What this means) is
that people (who chew too quickly ) end up eating too much food
because they still feel hungry.
从你开始吃东西到你的大脑告诉你的身体（你已经吃饱了）大约需要20分钟。
（这意味着）（咀嚼太快的人们）最终会吃太多食物， 因为他们仍然感到饥饿。
Eating slowly also allows your body to digest your food
better, and will allow you to enjoy your food more.
In addition, studies show (that consistent eating habits, for example, taking three meals a day at the same time each day, are better for our health).
It is also better to eat a modest amount of food each time, rather than to eat a lot in one meal, and then a little in the next.
此外，研究还表明（例如，保持规律的饮食习惯，比如每天在同一时间吃三餐，对我们的健康更有益）。
There is no one trick to healthy eating. Rather, healthy eating starts with having a healthy attitude towards food. One question (you can ask yourself) is,“Do I eat to live, or live to eat ”
If you are using food mostly for nutrition, then you are on the right track with
your diet. However, if food has become the centre of your life, you might be on the road to bad health. It is up to you to decide （how you want to live, and to make the right decisions about your diet.）
一个（你可以问自己的）问题是：“我是为了活着而吃饭，还是为了吃饭而活着？”
这取决于你，决定（你想要如何生活，并对你的饮食做出正确的决定。）
