Match the subheadings with the paragraphs.
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. 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. Put more simply, while people continue to argue over whether or not fatty food is dangerous, we already know that sugar is a killer.

StepⅢ Read for the writing methods
Paragraph 1
Paragraph 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.

Paragraph 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. 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.(Make a comparison;use linking words)(expressions for giving advice)

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. 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 each time, rather than to eat a lot in one meal, and then a little in the next.

Paragraph5
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.

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
