This year, I took the course of nutrition and really learned a lot. I learned the details of life nutrition that I didn't pay attention to before, and also accumulated some knowledge. What the teacher said is what we usually contact, even some basic common sense that we have always misunderstood. I think it is really necessary to study this course. It is of great help to our life and our health, so that we can have healthy eating habits. Teachers will also play videos in class for a correct understanding of nutritious food. For example, China on the Tip of the Tongue describes China's food culture, which is easy to read. I like this practical and relaxing classroom, and the teacher will also play some relaxing songs for us during recess. I really like it! Here are some of my experiences.
As the saying goes, health is the capital of revolution. With the continuous development of science and technology, health is really too important for us. Facing all kinds of delicious food in the present society, it is no longer a simple life. All kinds of delicious food are constantly emerging, and people are also very confused. A series of modern diseases such as obesity have also begun to appear. The course of food culture and nutrition and health care in China should be extended to be widely accepted by everyone. As contemporary college students, it is our unshirkable responsibility to learn and promote healthy eating. We should not only achieve a balanced diet, but also pay attention to developing good eating habits. When I was at school, I followed my feelings every time I went to the canteen to eat, and sometimes I was picky about food. To sum up, I find that I have only eaten a few monotonous dishes for several months. More than half of the dishes have not been eaten. After the nutrition class, I began to balance my diet. I want to balance all aspects of nutrition. I also began to eat an egg every day, eat more vegetarian dishes and fruits, try my best to diversify and make myself healthier. Before studying this course, I was not really interested in nutrition and health. I thought as long as I ate more, I could eat what I liked. But after listening to the teacher in class, I found that my previous eating method was too unscientific.
These premises are that we should know what nutrition is. Nutrition refers to the total process of digestion, absorption and utilization of nutrients in food in order to maintain growth and development, tissue renewal and health. The whole process of a person's life is inseparable from nutrition all the time. Therefore, people have the most common and basic requirements for food. And what state belongs to health? Health: According to the definition of the World Health Organization (WHO), health is a state of good physical, psychological and social adaptation, not just the absence of disease or weakness. The world-recognized health signs are 13: energetic, cheerful and energetic, normal height and weight, smooth and shiny hair, firm and reddish nails, pink tongue, strong appetite, normal body temperature, pulse and respiratory rate, healthy skin, normal urination and defecation, not easy to get sick, bright eyes, pink conjunctiva, healthy gums and oral mucosa. Some people sum up people's pursuit of food as four characteristics: eating omnivores, eating coarse grains, eating wild food and being vegetarian. From the point of view of nutrition, these four characteristics should be combined and reasonably matched, which may be more in line with people's needs for various nutrients. For middle-aged and elderly people, reasonable collocation is more important. Through the teacher's explanation in class and the expert's speech in the video, I know the reasonable way of diet collocation. Reasonable diet is to choose a variety of foods, so that the nutrients contained are complete and the proportion is appropriate to meet the needs of the human body.
1. Coarse grains should be matched with flour and rice: a reasonable combination of coarse and fine grains can improve the flavor of food, help supplement various nutritional components, and also improve the nutritional value and utilization rate of food.
2. The types of non-staple foods should be diversified, and meat and vegetables should be matched: meat, fish, milk, eggs and other foods are rich in high-quality protein, and various fresh vegetables and fruits are rich in vitamins and inorganic salts. The combination of the two can cook a variety of delicious dishes, which are not only nutritious, but also stimulate appetite, which is beneficial to digestion and absorption.
3. Matching of staple food and non-staple food: staple food refers to food crops mainly based on carbohydrates. The staple food can provide the main heat energy and protein, and the non-staple food can be supplemented with high-quality protein, inorganic salts and vitamins.
4. Lean diet: The staple food should be lean and lean according to the specific situation, which can increase satiety and help digestion and absorption.
5. Adapt to seasonal changes: the diet in summer should be light and refreshing, and hydrochloric acid food should be appropriately increased to increase appetite and supplement salt loss caused by sweating. Winter meals can increase oil content appropriately to increase heat energy.
6. Acid-base collocation: In the long-term struggle with nature, the working people in our country have left a rich diet culture, which needs to be explored and improved by modern scientific theory and technology. For example, some areas in the south pay attention to eating eel and lotus root together. It turns out that eel contains mucin and mucopolysaccharide, which can promote the absorption and utilization of protein, and is rich in completely protein, so it is an acidic food. Lotus root is rich in asparagine, tyrosine and other special amino acids, as well as vitamin B 12 and vitamin C, which belongs to alkaline food. This kind of acid-base and the supplementary nutrients contained in it have played a very good role in maintaining the acid-base balance of the body. Therefore, some western scientists strongly promote China's cuisine collocation and cooking methods.
After learning this course, I think the biggest gain is that it can help me live a healthy life in the future. I got not only this knowledge, but also my interest in nutrition, because she let me know about nutrition and benefited a lot in my future life and work. You can arrange a reasonable and healthy lifestyle for yourself. In life, pay attention to the reasonable arrangement of diet and daily life. As the saying goes, going to bed early is full of energy. A reasonable diet is not picky about food. Pay attention to a balanced diet. Through a comprehensive physical examination, specify the corresponding recipes for yourself. If you are weak, you should pay attention to the intake of protein, vitamins and minerals. Then there is proper physical exercise, which is also a key issue. Life lies in exercise, and proper exercise can definitely strengthen a person's system. The main thing is to have a regular life and a regular diet and daily exercise. It is better to eat and sleep regularly like a pig to keep fit on a whim. Then don't be partial to food, eat a little of everything, no matter what others say, as long as it is normal and healthy, we should eat a little. A healthy attitude is very important. We should have a positive attitude, learn to face failure and gloom and step on them. Although this course is over, I won't stop studying nutrition. I will pay close attention to every bit of nutrition in my future life!
