Step3 Close Reading
①There is much debate nowadays as to what makes up a healthy diet. ②For example, scientists have insisted for years that a big enemy of health is fatty food. ③ However, there is increasing evidence that the real driver of poor health is not so much fatty food, as it is sugar. ④ Heart disease is the number one killer of Americans. ⑤ 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). ⑥ This is true regardless of how healthy the rest of their diet might be. ⑦ Put more simply, while people continue to argue over whether or not fatty food is dangerous, we already know that sugar is a killer.

Para. 2
① sources of sugar
② American sugar intake
Main idea: reducing sweets is key.
①Much of this extra sugar comes from sweets and sweet drinks. ②The average American gets 1/3 of his or her sugar through sweet drinks alone. ③The 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. ④In other words, if you want to be healthy, you have to cut down on desserts, and cut out sweet drinks altogether.

Para. 3
① fresh

② processed

contrast
Main idea: keep it fresh and balanced.
①Beyond 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. ②Processed foods often contain less nutrition, and have higher quantities of sugar, salt, and fat than fresh ingredients. ③Besides 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. ④As with everything in life, moderation is key. ⑤The ideal diet is a balanced one, without too much or too little of any one thing.

Para.4
① slow eating
Main idea: slow eating is good.
①Finally, a fundamental key to healthy eating is to eat slowly. ②It takes about twenty minutes from the time you start eating for your brain to tell your body that you are full. ③What this means is that people who chew too quickly end up eating too much food because they still feel hungry.④ Eating slowly also allows your body to digest your food better, and will allow you to enjoy your food more. ⑤In 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. ⑥It is also better to eat a modest amount of each time, rather than to eat a lot in one meal, and then a little in the next.

Para.5
① ②attitude
Main idea: the way you look at food is most important.
①There is no one trick to healthy eating. ②Rather, healthy eating starts with having a healthy attitude towards food. ③One question you can ask yourself is, “Do I eat to live, or live to eat ”④If you are using food mostly for nutrition, then you are on the right track with your diet. ⑤However, if food has become the centre of your life, you might be on the road to bad health. ⑥It is up to you to decide how you want to live, and to make the right decisions about your diet.

One possible version
Dear Smith,
I am sorry to hear about your health issues. I understand how you feel and I am writing to give you some advice.
As the saying goes,“You are what you eat.” Healthy eating
is important in our daily life. To begin with, I recommend
that you start your day with a nutritious breakfast as it provides essential energy to start a new day. In addition, you can keep healthy by choosing whole grains and fruits instead of fried foods since they offer more sustained energy and vital nutrition. Finally, it is also important to drink water rather than sugary drinks because it hydrates you effectively without the empty calories.
I hope you will be better soon.
Yours,
Li Hua
Thanks!
