Introduction of the Chinese Food Guide Pagoda 2022
Before-reading
The Chinese Food Guide Pagoda is a graphic representation of the quantity and proportion of various foods intake for an adult according to the key recommendations from Dietary Guidelines for Chinese Residents (2022). It follows the principle of a balanced diet and shows the basic food composition in nutrition.
There are five levels on the Pagoda, each of a different size, showing the five categories of food and their amounts. The categories of food include cereals and tubers, fruits and vegetables, meat, poultry, dairy, soybeans, legumes and nuts, cooking oil and salt.
The food quantities are designed according to different energy demand levels. The notes beside the Pagoda indicate the recommended range of daily intake per adult at the energy demand level of 1600~2400 kcal.

Before-reading
Level 1: Cereals and tubers
Cereals and tubers are the main sources of dietary energy (carbohydrate provides 50%~65% of total energy), and they are also good sources of micronutrients and dietary fiber. It is recommended in the Dietary Guidelines that healthy people over two years old should eat diversified and balanced meals. A total daily intake of 200-300g of cereals, of which whole grains and legumes should make up 50-150g and tubers 50-100g, is recommended.
Level 2: Vegetables and fruits
People should eat enough vegetables and fruits, according to the Dietary Guidelines. The recommended daily intake of vegetables is 300g, half of which should be dark-colored, while the daily intake of fresh fruits should be 200-350g.

Level 3: Fish, poultry, meat, and eggs
Fish, poultry, meat, and eggs are recommended by the Dietary Guidelines for moderate consumption. Total intake should be targeted at 120-200g on a daily basis.
Level 4: Dairy, soybeans and nuts
Dairy, soybeans and nuts are good sources of protein and calcium with high nutrient density. A wide variety of dairy products should be consumed, and a daily intake equivalent to 300g of liquid milk is recommended.
Level 5: Cooking oil and table salt
Cooking oil and table salt are indispensable as cooking condiments, but it is better to use them as little as possible. The daily intake of salt and cooking oil for an adult should be less than 5g and 25-30g respectively. According to the recommendations of DRIs , the dietary fat energy supply ratio should account for 35% of the total dietary energy for people aged 1~3 years old; for people over four years old, it should be 20%~30%.
Before-reading
A food myth is a widely believed but misleading or false idea about food, nutrition, or eating habits. These myths can come from outdated advice, marketing hype, or just plain misunderstandings, leading people to make choices that don’t align with what’s actually healthy, beneficial, or based in science.
WHAT IS A FOOD MYTH?
While-reading
“Only fruit and vegetables are healthy foods.”
The human body needs to eat manydifferent types of food to stay healthy. The Chinese Food Guide Pagoda shows us what food we should eat. While fruit and vegetables are healthychoices, it is just as important to eatfoods from other food groups. Milk for example, contains many nutrients and is good for our bones. We shouid include milk or dairy products among thethingswe eat.
Food Myths
While-reading
“Eating fat makes you fat.”
Eating fat is important for keeping us healthy. It gives us energy and helps our body to take in nutrients. Not all fat makes us gain weight. Some fat can even encourageour body to lose weight. It is necessary to include some, but not too much fat in our food to help our body work well.
“It's OK to eat only what I like while I'm young.”
When we are young, it might feel like we can just eat whatever we want! For example, sweets and fried foods taste delicious. But wecannot eat those foods alone. Eating balanced meals is very important when we are young. It helps our body and brain to grow well. Bad eating habits may stay with us our whole life, so it is best to learn good eating habits early!

Milk is a great source of calcium, and calcium is necessary for strong bones and teeth, which helps your body maintain muscle movement, blood clotting and nerve signaling.
Milk is a good source of high-quality protein. Your body needs protein in order to build and repair cells in your muscles, bones and skin.

5. Do you agree with the ideas in the text? Is there anything you might change about your eating choices?

Read the text andanswer the questions.
Post-reading
Yes, I do. I think fruit and vegetables are healthy foods, but we should have a balanced diet to keep healthy. So we should include some fat in our meals. What’s more, we should keep a healthy diet as early as we can. If we do this when we have problems, it will be too late.
I have to change my eating choices too. Now, I have many vegetables and fruits every day, but I don’t have enough meat. I don’t think it’s a healthy diet, so I need to make a change. Also, I usually have some junk food and soft drinks. It’s time for me to stop or have little of them. I should drink more boiled water or juice and milk instead of soft drinks.

Brainstorm other beliefs about healthy food and eating habits. Which do you think are true? Discuss your ideas.

BROWN EGGS ARE HEALTHIER THAN WHITE EGGS
There is no nutritional difference between white and brown eggs. For some reason, many of us have grown up thinking that the darker shell means it’s a healthier food. It’s just not so. However, I’ll tell you all about the awesome of eggs in this post on the benefits of eggs.
The Mayo Clinic notes other types of alcohol can have positive effects on your health. Observational studies have determined that although red wine and the resveratrol contained in it are beneficial, beer, wine, and spirits all offer the same cardioprotective benefits. Keep in mind, this is for moderate consumption of alcohol.
RED WINE IS THE ONLY ALCOHOL THAT IS GOOD FOR YOU
The fact that vegetables are often taken from the field and flash-frozen or canned within a short period busts this myth. Li, et al studied the nutrient value of both fresh and frozen fruits and vegetables over a 2-year period, and determined there to be "no significant difference."

FRESH VEGGIES ARE BETTER THAN FROZEN OR CANNED
Gluten-free is not necessarily better for the general population, unless you have a gluten intolerance. Those who do lack the ability to digest gluten will have to avoid wheat, barley, and rye. The rest of us can benefit from the fiber and other nutrients in these foods. The reality is, only about 1% of the population has gluten-intolerance.
Additionally, I've found many highly processed ingredients in gluten-free pre-packaged foods, including canola oil, xantham gum, cane syrup, etc.
GLUTEN-FREE FOOD IS BETTER FOR YOU
The humble white potato gets short shrift, but it shouldn’t. “People demonize potatoes over sweet potatoes, but the nutrient composition is quite similar,” says Sharp. Sweet potatoes have more vitamin A and an additional gram of fiber, but white potatoes have more potassium (essential for helping regulate blood sugar), she says. Nutrition info from the U.S. Department of Agriculture on sweet and white potatoes backs up these details. The verdict: Include a combination of sweet and white taters in your diet.

Sweet Potatoes Are Healthier Than White Potatoes
While late-night snacking can lead to weight gain or prevent weight loss, it's not because of the time on the clock. Instead, it's about why you're eating. It's common to reach for food for reasons other than physical hunger in the evening, whether it be a habit, boredom or craving.
You shouldn't eat anything after 7 p.m. — not even a grape.

They can have different colors and shapes. They can be both red or green, round or sharp, big or small, and more importantly, they can be loved or hated by someone. What can they be? Right, the answer is chilies (辣椒).
Many of us in China enjoy adding chilies to our food, but do you know that this spicy (辣的) vegetable could also be very dangerous? A 34-year-old US man lost his life in hospital after eating a Carolina Reaper, the spiciest chili, reported by BBC News.
In fact, eating spicy food causes stomachache and headache. But if chilies are harmful, why do people eat this vegetable? What makes people love chilies so much? The human body is influenced (影响) by natural chemicals (化学物质) that produce “a sense of happiness”. That means chili makes them happy.
And chilies are good to people in another way. A study shows that the people who love eating chilies can live longer. This makes people eat more spicy food to make their health better. So don’t worry if you love spicy food. It seems that chilies are really good for us.
