HEALTHY EATING

There is much debate nowadays as to<1> ①what makes up<2> a healthy diet.For example, scientists have insisted<3> for years that a big enemy of health is fatty food.However, ②there is increasing evidence that the real driver<4> of poor health is not so much fatty food, as it is sugar.Heart disease is the number one killer<5> of Americans.And in America, people ③who receive 25% of their daily calories<6> or more through sugar are twice as likely to<7> die from<8> heart disease than people ③who receive less than 10% a day (Journal of the American Medical Association<9>， 2014).This is true regardless of<10> how healthy the rest of their diet might be.④Put more simply, while people continue to argue over whether or not fatty food is dangerous, we already know that sugar is a killer.

①本句是what引导的宾语从句，同时what在从句中作主语。

②that引导同位语从句，解释说明evidence的具体内容；as it is是一种语言衔接结构，意为“事实上，实际情况是”，多用来陈述一种原因或状况，尤其是该原因或状况与你的预期或期待存在不同时。

③who引导定语从句，分别修饰前面的先行词people。

④此处主句为we already know…，主句中that引导宾语从句；while引导状语从句，从句中whether引导宾语从句。

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<11>．⑤The American Heart Association recommends<12> that we limit ourselves to<13> 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<14>， if you want to be healthy, you have to cut down on<15> desserts, and cut out<16> sweet drinks altogether.

⑤recommend后引导宾语从句，从句用虚拟语气(should＋do，should可省略)；which引导非限制性定语从句，修饰先行词100～150 calories。在定语从句中又包含what引导的宾语从句。

Beyond this, you can keep healthy by consuming different categories<17> of fresh foods, especially fruit and vegetables, ⑥which are full of vitamins<18> and fibre<19>， rather than<20> processed foods.Processed foods often contain less nutrition, and have higher quantities<21> of sugar, salt, and fat than fresh ingredients.Besides<22> this, it is also important to have some meat, beans, or dairy<23> products in your diet, ⑦as they provide the necessary protein for strong bones and muscle growth.As with<24> everything in life, moderation<25> is key.The ideal<26> diet is a balanced one, without too much or too little of any one thing.

⑥本句是非限制性定语从句，修饰fresh foods。

⑦本句是as引导的原因状语从句。

Finally, a fundamental<27> key to<28> healthy eating is ⑧to eat slowly.It takes about twenty minutes from the time you start eating for your brain to tell your body that you are full.⑨What this means is that people who chew<29> too quickly end up<30> eating too much food because they still feel hungry.Eating slowly also allows your body to<31> digest your food better, and will allow you to enjoy your food more.In addition<32>， studies show that consistent<33> eating habits, for example<34>， ⑩taking three meals a day at the same time each day, are better for our health.It is also better to eat a modest<35> amount of food each time, rather than to eat a lot in one meal, and then a little in the next.

⑧不定式短语to eat slowly在句中作表语。

⑨此处为主从复合句。what引导主语从句，that引导表语从句，从句中who引导定语从句，because引导原因状语从句。

⑩此处是动名词短语作例子说明前面的主语eating habits。

There is no one trick<36> to healthy eating.Rather<37>， healthy eating starts with<38> having a healthy attitude towards<39> food.One question you can ask yourself is, “Do I eat to live, or live to eat？” If you are using food mostly<40> for nutrition, then you are on the right track<41> with your diet.However, if food has become the centre of your life, you might be on the road to bad health.⑪It is up to you to decide how you want to live, and to make the right decisions about your diet.

 ⑪It is up to you to decide…是固定句式“It is up to sb to do sth(由某人决定做某事)”。and连接两个不定式短语to decide…和to make…。

<1>as to至于，关于(＝as for)

<2>make up组成，构成

<3>insist坚持说(后跟的宾语从句用陈述语气)；坚决要求(后跟的宾语从句用虚拟语气)

<4>driver n．驱动因素

<5>killer n．杀手，导致死亡的人(或动物、事物)

<6>calorie/ˈkæləri/

n．卡路里(热量单位)

<7>be likely to do sth 很可能做某事

<8>die from 死于

<9>association/əˌsəʊʃi

ˈeIʃn/n.协会；关联

<10>regardless/rIˈgɑːdləs/
