Detailed Reading
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.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.

Detailed Reading
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.

Detailed Reading
Beyong this, you can keep healthy by consuming different categories
of fresh foods, especially fruit and vegetables, which are full of vitamins and fiber, 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 diets, 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.

Para.4
What is the key detail that support the point
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.
What other suggestions does the author give
consistent eating habits
a modest amount of food
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.

Possible version:
Only after writing down what I have eaten over the last three days, do I realize how healthy/ unhealthy my eating habit is.
There are some foods that I shouldn't eat too much. For example, I like eating processed food rather than fresh food because of its convenience. However, as we all know, processed food often contain less nutrition, and have higher quantities of sugar, salt, and fat than fresh ingredients, which is certainly not good for health.
Therefore, I should improve my bad eating habits by cutting down eating processed food. As long as I follow a balanced diet, I am convinced that I will be much healthier and happier.

Useful words
and expressions
Dear Mike,
Learning that you don’t like eating fresh vegetables, eggs, coarse grains and even dislike drinking milk, I feel concerned about your health and would like to share some suggestions with you.
To be honest, you'd better attach great importance to keeping a balanced diet, which is of great importance to your body and study. It is widely believed that fresh vegetables and milk contain plenty of minerals as well as vitamins we need. Besides, proteins, which we mainly get from eggs and beans, play a vital important role in building up a strong body.
Wish you good health and great progress in your lessons! Yours, Li Hua
