Class meeting on the theme of "snacks and health"
Activity background:
Snacks refer to all kinds of food or drinks (excluding water) eaten during non-dinner time. Almost all children in the world have the habit of eating snacks. In China, in recent years, the proportion of children eating snacks has gradually increased due to the influence of western dietary patterns and the increase of food types and advertisements. Many students in the class like to eat snacks. Although the school has repeatedly banned students from eating snacks on campus, some students still bring snacks in secretly, and more often they buy those worrying three-no products in front of the small shop at the campus gate. Even after showing them a lot of junk snacks and dirty production processes, they still can't resist the temptation of snacks. It is better to dredge than to block it. Love to eat is a child's nature, so we will guide children to eat moderately and selectively.
Activity purpose:
1, let students improve their ability to distinguish junk snacks from healthy snacks through practical activities.
2. Know the hazards of junk snacks and learn how to choose healthy snacks.
Learn to control pocket money reasonably and eat less snacks to keep healthy.
4. Through the investigation of snack packaging in shops, pay attention to the pollution of plastic waste caused by overeating snacks, improve environmental awareness and develop good hygiene habits.
Activity preparation:
1. Identify several research topics. Each group is free to choose the tasks they are interested in, investigate and study separately, and then summarize the data to complete the content connection of the whole theme class meeting.
2. Make PPT according to the topics and contents reported by each group.
Activity flow:
First of all, the monitor spoke:
Today, the theme of our class meeting is snacks and health. What is a snack? Snacks refer to all kinds of food or drinks (excluding water) eaten during non-dinner time. Almost all children in the world have the habit of eating snacks. In China, in recent years, the proportion of children eating snacks has gradually increased due to the influence of western dietary patterns and the increase of food types and advertisements. Some students eat snacks for a long time, leading to anorexia and malnutrition; Others eat too much and are overnourished. Some people eat too much, causing physical harm; Others cause excessive consumption and environmental pollution.
In this class meeting, we will focus on the topic of snacks and health, improve the correct understanding of snacks through the practical activities of each group in the previous stage, help everyone learn to choose healthy snacks scientifically, identify junk snacks, consume rationally, and pay attention to the environmental pollution caused by eating snacks.
Second, each group reports the results of their own practical activities:
(a) Our questionnaire
Chairman of * * * * Group: We interviewed customers randomly in the supermarket in the early stage and found that adults also eat snacks, but they pay more attention to choosing nutritious and healthy snacks than we do, and eat less, unlike us, they can't control it once they eat. You see, according to the statistics of scientists, a child eats a mountain of snacks every year. They vividly said that those manufacturers and vendors simply regarded children as trash cans. Because of their ignorance, they dare to put all kinds of additives in snacks, regardless of how much harm it will cause to children!
Let's take a look at the questionnaire survey on snacks made by * * * Group.
Our group's questionnaire1* * has seven questions, and the survey results are as follows:
1. In our class, 60% students like snacks and 22% students don't like snacks.
2. Parents' attitude towards our snacks is 0.0 1% for it,1%for it, and 59% for it.
3. The hazards of eating too many snacks account for 22% clearly and 78% unclear.
4.43% can distinguish healthy snacks from junk snacks, while 29% can't.
5. 18% know how to eat snacks to be healthy, while 79% don't.
6. The cost of eating snacks every day is 0/-45% in 4 yuan and 52% in 5 yuan, 5 yuan.
7.6% people are aware of the harm of snacks to the environment and pay attention to this problem, and 9 1% people are not aware of it.
8. After eating snacks, 43% of the bags can be thrown into the trash can and 56% can be thrown away.
According to our survey results, we think it is very necessary to hold such a theme class meeting. People really know too little about snacks. If nothing else is said, the consumption of snacks is calculated at one yuan per day for 30 days. If you eat it every other day instead of every day, you can save 15 yuan in one month and 180 yuan in one year. If you calculate by five yuan a day, you can save 75 yuan a month and 900 yuan a year. Think about how much we can do with this money.
(2) Confessions of junk snacks
* * * * Group presided over the speech:
Many of our classmates like to eat snacks, and they eat many kinds. For example, colorful candy, pepper strips and so on are placed in the booth in front of the campus. As we all know, snacks are also divided into junk snacks and healthy snacks. Junk food refers to food with less nutrients, more additives (or harmful ingredients) and no special health care effect. Eating junk food for a long time may damage your health. Therefore, you should try to eat less or not. If you look at the packaging carefully, you will find that many street snacks are typical three-no products. When you eat these snacks, some harmful substances also sneak into your body. However, we often linger in front of junk snacks.
Let's welcome ladies and gentlemen like jelly, potato chips and biscuits to talk about themselves. Let's clap!
(1) Jelly: Eating me will not only fail to supplement nutrition, but even hinder the absorption of some nutrients. My ingredient is carrageenan, a carbohydrate that the human body can't absorb. Basically no fruit juice, the sweetness comes from refined sugar, and the fragrance comes from artificial essence. You can't expect to use me to increase nutrition.
(2) Potato chips: I am a sweet potato chip, and many students can't resist my tasteless temptation! In fact, what you don't know is that my nutritional value is actually very low, and I also contain a lot of fat and energy. Eating too much will destroy my appetite and easily lead to obesity. I am also the enemy of skin bodybuilding!
(3) Spicy strips and shrimp strips: Do you know? Although I don't have any nutritional value at all, the spicy taste and shrimp taste in it are all synthetic flavoring agents, and the pigment spicy agent in it will poison the body, make the body unable to develop normally, and affect the height and vision. But my classmates just think I'm delicious, full of flavor and spicy enough. Even though I have no products, they still eat and eat badly. Can you blame me? !
(4) Fast food noodles: high fat content and low nutritional value. Eating too much is not conducive to a balanced diet. Moreover, the content of preservatives in my body is the highest, and excessive consumption leads to the decline of human immunity. But it's not my fault, it's all because they can't control their mouths.
(5) Cookies: I am a high-fat and high-energy food, but the content of vitamins and minerals is relatively small, so it is ok to eat less. Eating too much is not conducive to a balanced diet and can easily lead to obesity!
(6) Bubble gum and chewing gum: My nutritional value is almost zero. Some products contain a lot of preservatives and artificial sweeteners, especially some inferior products, which are very harmful to health! But students just like to chew us in their mouths and throw up everywhere at any time. There is nothing we can do!
(7) Popcorn: In order to make my taste more attractive, I added a lot of margarine and some essence; In order to make me more beautiful, I have to add some paint to it and put on a beautiful coat for me. However, the extra energy brought by this margarine will bring obesity closer to everyone, and too much artificial pigment intake may lead to ADHD in children.
(8) Ice cream, ice cream: My margarine content is very high, commonly known as hydrogenated oil, which is particularly prone to obesity; Because of the high sugar content, it will also reduce appetite; And it may stimulate the stomach because of the low temperature, but as the weather gets hotter and hotter, many students will still desperately want to eat. Hey, don't come to me if you gain weight and have a stomachache!
(9) Ham sausage: bright color, Q-bomb taste, full meat flavor and qualified protein content, all of which have nothing to do with pork! Colorants, preservatives, spices, skins, pig water, pig blood and soy protein isolate are all stuffed into various casings. I give you the feeling of meat, but I don't give you the nutrition of meat! Don't blame me for lying to you Who told you to lie?
(10) Milk tea: Although my name is milk tea, it has nothing to do with milk. Why do you ask me? Because ten cups of fresh milk are not as fragrant as a spoonful of cream. Save money! I can buy 10 yuan, which was only worth one yuan at that time! Eating too much cream is harmful to your health. Long-term consumption is more likely to induce arteriosclerosis and increase the chances of suffering from coronary heart disease, tumor, asthma and other diseases.
(C) the harm of excessive additives
* * * Group Chairman: (In this session, each group interspersed the instructions on the snack bag to observe and find the additives in the snacks)
After listening to their introduction, some snacks are really harmful to our health. Our group carefully analyzed the harm caused by the main additives in several snacks that students often eat. Please listen to our report:
(1) Excessive pigment. Some food producers often overuse synthetic pigments, such as puffed food and candy, in order to look good on snacks. However, the risk of synthetic pigments to human body is higher than that of natural pigments. If you eat a lot of food with excessive pigment content for a long time or at one time, it may cause symptoms such as diarrhea, decreased immunity and affect long-term people.
(2) There are preservatives exceeding the standard. Some foods are added with chemical synthetic substances, such as benzoic acid, potassium sorbate, nitrite, etc., to ensure the anti-corrosion needs of food during transportation and storage. Excessive intake will inhibit bone growth to a certain extent and endanger the health of kidneys and liver.
(3) I also said that some snacks may add excessive saccharin to candied fruit, ice cream, cakes, biscuits and other foods in order to improve sweetness, which will cause gastrointestinal discomfort and liver metabolism problems. Saccharin will also form cyclic ethylamine after hydrolysis, which poses a cancer threat.
(4) Some snacks, such as preserved plum and dried bean curd, contain a lot of salt or sugar, which will increase the burden on the kidneys and pose a threat to the cardiovascular system.
(5) At present, most of the pastry, ice cream and biscuit ingredients on the market contain vegetable butter and vegetable butter, which contains a lot of trans fatty acids. Excessive intake will damage children's intelligence and heart.
(6) If you eat these foods containing excessive additives, pigments and preservatives for a long time, it is easy to cause symptoms such as depression, inattention, poor self-control, behavioral quirks and loss of appetite.
(7) According to media reports, Li, 12-year-old from Xiangtan City, suffered from chronic suppurative osteomyelitis because of his picky eaters and love of snacks. After illness, the right leg stopped growing, and the right leg was shorter than the left leg by nearly 10 cm. Others have purple spots on their legs because they are greedy for snacks, and some have tonsil inflammation because they eat too many snacks.
New Choice of Healthy Snacks
* * * group presided over the speech:
It's terrible. We must learn to protect ourselves and resolutely refuse junk snacks. Eat less snacks. However, according to the survey, snacks are not harmful. Protein, fat and carbohydrate provided by snacks account for a certain proportion of the nutritional intake in a day. At the same time, snacks can also provide a certain amount of trace elements for people to obtain certain nutritional supplements.
For healthy snacks, they are low in sugar, fat, calories and cholesterol, and do not contain chemical additives (such as artificial colors, preservatives and monosodium glutamate). ) are all prerequisites. Our group carefully selected some healthy snacks for everyone. Let's listen to their opinions!
1. Sunflower seeds contain protein, fat, vitamins and minerals, especially linoleic acid. Linoleic acid helps to keep skin soft and prevent skin dryness and pigmentation.
2. Vitamin B2, which is rich in peanuts, is one of the vitamins that China residents lack in their daily diet. Therefore, deliberately eating more peanuts can not only supplement the deficiency of vitamin B2 in daily diet, but also help to prevent and treat many diseases such as cleft lip, itchy eyes and seborrheic dermatitis.
3. Walnut is rich in auxin, which can make nails firm and not easy to crack. At the same time, walnuts are rich in plant protein, which can promote the growth of nails. Eating walnuts often helps to increase the toughness of nails and is not easy to crack.
4. Jujube is rich in vitamin C, which is called live vitamin C pill by nutritionists. Without vitamin C in the diet, people will feel tired and even get scurvy.
Cheese is rich in calcium, which can strengthen teeth. Nutritionists show that an adult who eats150g cheese every day will help to achieve the goal of never aging.
6. Figs contain a chemical similar to aspirin. Can dilute blood, increase blood flow, so that the brain can supply enough blood.
7. Sesame paste has the functions of blackening hair, moistening hair and nourishing blood. It can prevent white hair and alopecia, and make hair black and bright.
8. Pumpkin seeds and pistachios are rich in unsaturated fatty acids, carotene, peroxides and enzymes. Proper consumption can ensure cerebral blood flow and make people energetic and radiant.
9. Citrus, oranges, apples and other fruits are rich in vitamin C, which can slow down or block the synthesis of melanin, whiten the skin, and are alkaline foods, which can keep the blood neutral or weakly alkaline, thus having the effect of fitness and beauty.
10. Eating some chocolate in moderation can relieve mood, improve attention, memory and intelligence, prevent cardiovascular diseases, enhance immunity, prevent cancer, interfere with tumor blood supply, delay aging and make people feel happy, beauty beauty.
1 1. Raisins have the functions of benefiting qi, enriching blood and beautifying. But pay attention to hygiene.
12. Mint can moisten the throat, remove bad breath and dissipate internal heat, which makes people feel refreshed.
13. Beef jerky and grilled fish fillets are rich in protein, iron and zinc. Moderate consumption can make people's skin rosy.
(5) What should I pay attention to when choosing snacks?
* * * group presided over the speech:
Students, even healthy snacks can replace our dinner? Of course not. No matter how good snacks are, they can't supply all the nutrients our bodies need. Excessive consumption can also lead to obesity or weight loss. Look, this is the nutrition pyramid that our human body needs every day. There are seven main nutrients I take in food: protein, sugar, fat, vitamins, water, inorganic salts and crude fiber. Please look at the location of snacks in the pyramid. The spire, yes. This means that you must eat less snacks. Ok, so what should I pay attention to when choosing snacks? Our findings are as follows:
(1) Should I listen to advertisements when choosing snacks? Of course not. We should learn and understand the nutritional characteristics of different snacks. We should not blindly follow advertisements to choose snacks. To get into the habit of reading the snack ingredient list, choose regular products with few additives, rich nutrition, manufacturers and addresses, and green food safety labels.
(2) Snacks should be an integral part of a reasonable diet. Don't just choose snacks from tastes and preferences, choose fresh, natural and digestible snacks, and choose more foods such as milk, fruits and vegetables and nuts.
(3) Don't eat snacks when you are too close to dinner. Generally, you should eat snacks no more than three times a day.
(4) Eat snacks in moderation every time, avoid eating snacks while playing, and eat less fried, too sweet and too salty snacks.
(5) Develop the habit of drinking more white water, drink less sugary drinks, pay attention to personal hygiene and oral hygiene, and eat less street food.
(6) We believe that snacks should be eaten in different grades:
For example, boiled peanuts, fried soybeans, red dates, walnuts, pumpkin seeds and other fruits and nuts can be eaten regularly (daily).
Beef jerky, grilled fish fillet, dark chocolate, etc. (weekly 12 times) can be eaten properly.
The consumption of cotton candy, puffed food, egg yolk pie and ice cream should be limited (not more than once a week).
The class teacher organizes group activities:
1. Learn to read the description of snack products by using the snack packaging bag that you like to eat before class. Look at the column of additives in your favorite snacks and count how many additives there are. Then signal to the teacher with your finger and say the name of this snack, which will attract the attention of the students. The more additives, the heavier the body's metabolic burden. Should we choose more additives or less additives when going to the supermarket?
2. Understand whether there is a QS mark with a production quality license on the snack bag. Even with QS, choose fewer additives and increase the frequency of eating less.
(6) Snacks and environment
* * * * Introduction by the Chairman of the Panel:
Look at the behavior of our classmates again! These are some photos we have taken and collected about the environmental pollution caused by snacks. (Slide) After school, students gather around the booth in front of the campus and enjoy the snacks they bought. When I come to school at noon, it is not uncommon for many students to eat small potato chips and chewing gum in front of crowded booths and leave garbage bags. Peels and scraps of paper are everywhere at the entrance of the campus, and the beautiful and clean environment is polluted.
According to our investigation, most of the snack packaging bags on the market are plastic packaging, and the only environmentally-friendly paper packaging snacks are-if buried, it will pollute groundwater, if burned, it will pollute the air and cause death.
Students, we are in the golden stage of physical development. For our own health and the cleanliness of the campus, we suggest:
He: refuse junk snacks, eat properly and clean the campus. Start with me!
(1) Choose fresh, natural and digestible snacks, such as milk, fruits, vegetables and nuts.
(2) Learn and understand the nutritional characteristics of different snacks, and don't blindly follow advertisements to choose snacks.
(3) It is recommended not to eat at school too early and not to eat snacks too close to dinner. Generally, don't eat snacks more than three times a day.
(4) Eat snacks in moderation every time, and never eat snacks while playing, watching TV or going to school.
(5) Eat less fried, too sweet and salty snacks.
(6) Promote healthy drinking water and develop the habit of drinking more white water and less sugary drinks.
(7) Pay attention to personal hygiene and oral hygiene, eat less street snacks and stay away from junk food completely.
(8) Learn to be thrifty, reasonably control pocket money, and don't buy snacks indiscriminately.
Let's take action together, bid farewell to mobile stalls and junk snacks, and make our campus more beautiful and clean; Let our bodies be healthier and stronger!
* * * * The group presided over the speech: In order to help the students to be more impressed by the theme class meeting, our group also adapted a "Snack Safety and Hygiene Song" and taught it in the whole class. Please watch our performance:

* * * * Moderator: Health comes from life, just as light comes from the sun. With health, life is endless and shining.
All women: let's cherish ourselves!
All men: Let's keep healthy!
The class teacher organizes group activities:
1. Have we learned a lot through the reports of various groups today? Then use the knowledge you have learned today to classify the snacks in your hands according to your favorite way, and then tell you the method and result of classification.
Discuss in groups and report their classification methods.
The teacher also brought his favorite snacks, grilled fish slices and milk tea. I used to like drinking milk tea. Today, after listening to the students' research report, I counted it carefully. This milk tea actually has 1 1 additives, which is terrible. There are also hydrogenated vegetable oil and non-dairy creamer mentioned by everyone just now. Just now, everyone said that eating too many additives would be harmful to health, and I also want to be healthy. So today, I will also drink junk snacks and say goodbye. This grilled fish fillet has only one additive and looks healthier. Shall we share it after the class meeting?
Let's read our health declaration together, read more books, read more newspapers, eat less snacks and sleep more!
Monitor: This is the end of the class meeting entitled "Health and Snacks" for Class Six, Grade Four. Students, let's work together to reject junk snacks, cultivate good eating habits, choose healthy food scientifically, cherish ourselves and keep fit, shall we? ! Thank you!
