HEALTHY EATING
Para1: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.
make up 组成；构成；编造;和解；和好 makeup 化妆品
insist 坚持；坚决要求 insist on/upon doing sth 坚持做某事
insist +that 从句 insist 表示“坚持主张”和“坚决要求”时 that 从句用虚拟语气；而表示“坚持说”和“坚持认为”时则用陈述语气。The doctor insisted that he ( should )be examined.
He insisted that he was right.

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。
推手
as it is事实上，实际情况是
Heart disease is the number one killer of Americans. And in America，people (who定从，主 receive 25% of their daily calories or more through sugar) are twice as likely to die from heart disease than people （who定从，主 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. Put more simply，while people continue to argue over whether or not fatty food is dangerous, we already know that sugar is a killer.
be likely to do sth 可能做某事 die from 死于 less than 少于
regardless of不管;不顾后可接 名词 、代词或 宾语从句
argue about=argue over 意为“就...争论”
argue with sb over/about sth 与某人争论某事
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）。无论他们饮食的其他方面多么健康，都确实如此。简单的说，当人们还在为高脂肪食物是否有害而争论不休时，我们已知晓糖分是健康杀手。

Para2 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.adv完全.
本句recommend意为“建议”，后面跟that引导的宾语从句，从句使用了省略should 的虚拟语气。

换句话说
把...限制在...范围内
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1/3。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。

3. How does the writer support his topic sentence
Para3 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.
quantities of / a quantity of“大量的”，1；后接可数名词复数作主语时，谓语动词用复数；2；后加不可数名词作主语时，谓语的单复数形式由quantity 的单复数决定。
Quantities of nuts are on the table.
A quantity of nuts are on the table.
定语从句
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。

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.

此外，饮食中摄取一些肉类、豆类或奶制品也十分重要，因为这些食物为强壮骨骼、肌肉生长提供必要的蛋白质。适量是关键，生活中万事均如此。理想的饮食是均衡饮食，避免过多或过少摄入任何一种成分。

Para4

What’s the fundamental key to healthy eating
Eat slowly, regularly and eat in moderation(适量).
How does the writer support his key point
Para4 Finally, a fundamental key to healthy eating is to eat slowly. It takes about twenty minutes from the time （定从，省略when）you start eating for your brain to tell your body that宾从 you are full.What this means is that people
（who chew too quickly） end up eating too much food because they still feel hungry.?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.
It takes some time to do sth 花费时间做某事

最后，健康饮食的基本要诀是细嚼慢咽。开始进食大约20分钟后，你的大脑才会告知你的身体，你吃饱了。这意味着咀嚼过快的人最终会吃太多食物，因为他们仍然感到饥饿。细嚼慢咽还能让你的身体更好的消化食物，更充分的享受美食。此外，研究表明，有规律的饮食习惯对我们的健康更有好处，例如每天固定时间食用三餐，而且最好每餐摄入适量的食物，而不是上一餐吃很多，下一餐吃的很少。
Para5
How do you understand it
Para5 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.
on the right track 做的事情或想法是好的、方向是正确的。
be up to sb.to do sth.由某人决定做某事
up to多达(后常接数字)；从事；忙于;直到；取决于
up to sth.胜任某事 up to now到目前为止
up to date最新的；新式的
健康饮食没有诀窍，相反，健康饮食始于健康的饮食态度。你可以问自己一个问题，我是为了活着而吃饭，还是为了吃饭而活着？如果你吃饭主要是为了汲取营养，那么你已经在饮食上走对了路子。然而，如果食物已成为你生活的核心，那么你可能已踏上不健康之路。你想如何生活，如何做出正确的饮食抉择，这完全取决于你自己。
