1. A 200-word essay on the science of diet. When it comes to eating, everyone will definitely have a lot of experiences. Everyone has their own preferences, but how can we develop the habit of scientific eating?
Children must really like cold drinks!
Eating too much cold drinks can cause headaches and abdominal pain.
I remember one time: It was summer, the weather was very hot, when I got home from school, I drank a cold drink, wow!
It's so cool and you won't feel hot immediately after eating it.
When grandma wasn't paying attention, I secretly drank two more cups. It felt so comfortable.
But at night, I suddenly had a stomachache. My father looked at it and said, "I must have drank too much cold drinks!" After I got salt water from the hospital, my stomach pain stopped. I thought to myself: I will never drink cold drinks again.
Dad said boiled water is the best drink.
Eating too much chocolate can also cause abdominal pain.
I remember another time: Grandma bought some chocolate, because I like eating chocolate very much, and I was very happy.
I couldn't wait to say to my grandma: "Grandma, can you eat a few pieces of chocolate for me?" Grandma said: "Don't eat too much." I took out the chocolate, and as soon as I smelled the fragrance of the chocolate, I couldn't control it.
I ate many pieces of chocolate in my mouth at once.
After a while, I felt a severe stomach pain. I couldn't help it and went to have diarrhea.
Grandma said: "You glutton, I told you not to eat more, but you still eat so much. It's weird if you don't have diarrhea!" I will never dare to eat more chocolate in the future.
In addition to eating less drinks and chocolate, basically all foods cannot be eaten just because you love them.
Children, gluttony is a bad eating habit and we must correct it quickly.
2. An essay on reasonable diet requires 200 words. The significance of reasonable nutrition is to promote growth and development, prevent and treat diseases, enhance intelligence, promote eugenics and postnatal care, and enhance the body's immune function, so as to achieve the purpose of health and longevity.
Nutrients refer to substances in food that can provide energy, body components, tissue repair, and physiological regulatory functions to the human body.
At present, it is known that there are 40-45 kinds of essential nutrients for the human body, [2] among which the most important nutrients for the human body include protein, lipids, carbohydrates, vitamins, minerals, water and dietary fiber.
2. Health Overview With the development of economy and progress of society, human beings pay more attention to the quality of life and health.
The World Health Organization defines health as "health refers to a state of good physical, psychological and social adaptation, not just the absence of illness or a healthy body."
Based on this, ten standards of health were formulated: abundant energy, able to shoulder daily life and heavy work calmly without feeling overly nervous or tired; optimistic, positive attitude, willing to take responsibility, no matter how big or small, not picky; good at doing things.
Rest and sleep well; have strong adaptability and can adapt to various changes in the external environment; be able to resist common colds and infectious diseases; have an appropriate weight, a well-proportioned body, and coordinated head and shoulder positions when standing; bright eyes, quick reactions, and no eyelid inflammation
; Teeth are clean, no cavities, no pain, gum color is normal, no bleeding; hair is shiny, no dandruff; muscles are plump, skin is elastic.
It can be seen that people no longer equate health with the absence of disease. The concept of health care is increasingly widely accepted by people. People maintain a healthy body and a healthy mental state in various ways.
[3] 3. The relationship between nutrition and health Nutrition is the process in which a living body continuously absorbs the necessary substances from the outside world to maintain life activities.
Human beings maintain life, ensure growth and development, improve health and complete various activities through nutrition.
Human beings are inseparable from nutrition from fetus to death. The quality of human physique is closely related to nutritional status.
[4] Nutrition is a prerequisite for maintaining human life, the material basis for ensuring physical and mental health, and an important condition for human recovery.
In short, human life, old age, illness and death are closely related to nutrition.
Those substances needed to maintain normal growth, development and metabolism of the body are called "nutrients".
The functions of nutrients mainly include providing energy, promoting growth and tissue repair, and regulating physiological functions.
The basic unit of the human body is cells, cells constitute tissues, tissues constitute organs, and organs constitute human body systems.
The materials that make up cells come from nutrients in the food we eat, and they are used by the body to nourish the cells in our body.
Cell health undoubtedly determines human health.
There are currently more than forty known nutrients needed by the human body, and we can subdivide them into seven categories: first, carbohydrates, whose function is to maintain the activities of body cells, mainly derived from grains; second, lipids,
Its function is to maintain cell structure and function, mainly derived from oils (edible oils, fats, nuts); third, protein, its function is to maintain the activity of body cells, mainly derived from fish, meat, beans, eggs, milk
etc.; fourth is vitamins, whose function is to regulate physiological functions, mainly derived from vegetables and fruits; fifth is minerals, whose function is to build and repair body tissues and regulate physiological functions, mainly derived from vegetables and fruits; sixth is water, which
The function is to regulate physiological functions, and the main sources are beverages and soups; the seventh is dietary fiber, whose function is to prevent human gastrointestinal diseases and maintain gastrointestinal health, and comes from various plant foods.
