(3) Biological factors: including heredity, growth and development, and aging. (4) Health service: It means that the society has a good medical service and health care system, a necessary supply of medicines, and a perfect vaccine supply and cold chain system.

Second, the basic knowledge of health (1) Reasonable diet and nutrition 6. What are nutrients? Nutrients refer to the nutrients contained in food, including protein, lipids, sugars, vitamins, inorganic salts, trace elements and water. Different nutrients have different functions in body metabolism.

After a series of complicated metabolic processes such as digestion and absorption, nutrients in food can be used by various tissues and organs of the body to maintain life activities, promote growth and development, regulate physiological functions and ensure human health. 7. What is reasonable nutrition? Reasonable nutrition means that the quality and quantity of diet can meet the nutritional needs of people's physiology, life and labor, and it is a balanced diet.

In other words, reasonable nutrition means that we can get all kinds of necessary nutrients through diet. The contents of these nutrients in different foods are different, so it does not mean that only chickens, ducks, fish, eggs, milk and fruits have nutrition, while coarse grains and vegetables have no nutrition.

In the usual diet, coarse grains should be matched with flour and rice, and animal foods should be matched with plant foods, which is a reasonable and nutritious diet. 8.

9. How to arrange three meals a day reasonably? Three meals a day is the eating habit of our people, and it is also a traditional eating habit that conforms to nutrition and hygiene. As the saying goes, "Good breakfast, full lunch and little dinner" is very scientific.

Medical research has proved that high-calorie diet should be eaten for breakfast and light meals should be eaten for dinner. Why is this? Because, under normal circumstances, people have a lot of work in a day, especially in the morning, the human body consumes more calories.

Generally, there is little activity after dinner, so the calorie intake is naturally very small. Therefore, breakfast should be full of protein-rich food and eat well; Lunch should provide enough carbohydrate-containing food, such as rice, steamed bread, porridge, etc., to eat; It is advisable to have a light and greasy diet for dinner, and eat less; 70% is appropriate.

The correct distribution of three meals a day should be that breakfast accounts for 30~40% of the total meal, lunch accounts for 40~50%, and dinner accounts for 20~30%. The calorie content of dinner food should not exceed 30% of the calories needed for the whole day. Just ask health 10, why is it not good to advocate vegetarianism blindly? Some people think that animal foods are high in cholesterol and fat, which can easily cause cardiovascular and cerebrovascular diseases such as atherosclerosis, so they are vegetarian for a long time and don't touch meat.

In fact, this is a prejudice. Because from the point of view of nutrition, animal food contains protein and essential amino acids needed by human growth, tissue renewal and metabolism.

The fat contained in animal food is also necessary for human body. For example, lipids are an important part of human cells, protoplasm and nerve tissue, and phospholipids contained in lipids can also promote the transport of cholesterol in the body.

Therefore, proper intake of some animal foods is very beneficial to the human body, not to mention that animal foods also contain a large number of inorganic salts, trace elements and vitamins, which are necessary for the human body. Therefore, it is absolutely unnecessary for normal healthy people to blindly advocate vegetarianism, and it is not suitable for patients and manual workers. It is only suitable for middle-aged and elderly people who are overweight, overnourished and have high calorie intake.

1 1. How much protein do adults need every day? The main sources of protein in food are seeds (grains) and fruits (soybeans and peanuts) of plants and meat, viscera, eggs and milk of animals. How much protein a person needs depends on age, sex, working conditions and health status, and varies with food sources.

For example, a healthy adult man weighing 65 kilograms needs about 75~ 100 grams of protein (1.5~2 Liang) every day, which depends on his physical labor intensity. Generally, there are slightly fewer adult women.

12. How much oil is appropriate to eat every day? People often say that "more oil doesn't rot vegetables", that is to say, the more oil you put in cooking, the more delicious the taste and the better the appearance. This is true. However, from a health point of view, eating too much oil will do harm to your health.

So how much oil is appropriate to eat every day? According to the requirements of reasonable nutrition, when a person's average daily intake of animal food (meat, fish, eggs, poultry) reaches 150g, it is oily.
