3. What are the most basic health care knowledge in life?

First, the diet should be moderate and light.

"Huangdi Neijing" tells a truth: the amount of food is just to replenish qi, and eating too much hurts the body; Too strong a taste is harmful to health, and light a taste can refresh you. Laozi also said in Tao Te Ching: Eating too much delicious food hurts the stomach.

The second is to look at the nature of food and the needs of the body. Everything that can be eaten is sexual, and it is inseparable from the five attributes of cold, heat, warmth, coolness and flatness.

When the body is hot, it will be cold, and when it is cold, it will be hot. Such as: stomach heat, should eat cold bananas; Drink hot ginger soup when your stomach is cold.

If you eat backwards, you will get sick. For example, the climate between beginning of autumn and the autumnal equinox is hot and dry every year, so it is not suitable for spicy food, which may easily lead to fever in the stomach and large intestine, deafness and tinnitus.

Walking should also be dialectical. When you walk, you should put all your energy on your legs.

God can regulate his anger; Qi can mobilize the essence and inject it into the joints of the legs. The water flowing in the human body is called body fluid, which is relatively thin and runs through the skin. When the body temperature is hot, it passes through the sweat gland channel and when the body temperature is cold, it passes through the urethra.

This liquid is viscous and flows through human bones and muscles to lubricate joints. If people's walking energy is not on the legs, hip joints, knee joints and ankle joints, these "human bearings" will not get enough lubricating oil, and will wear the joints over time.

Walking also needs to grasp the strength. "Life lies in exercise."

This is a common saying. If you add the word "moderate", that is, "life lies in moderate exercise", this sentence will be scientific.

Walk lightly, and rest when your legs are tired. Because a tired leg is like a hot engine cylinder of a car, it will wear out the parts when it is restarted.

Walking time should be in the morning. Morning is spring, and spring takes the initiative; The liver is active, and it should be in the spring, governing the meridians and moving the meridians in the morning.

People eat fat not only because it can produce attractive fragrance, but also because it contains fatty acids needed by the human body and plays a nutritional role in the body. Its nutritional function mainly includes (1) providing energy; (2) Constitute human tissues (3) form components with physiological activity, and regulate physiological and biochemical reactions in vivo.

There are many kinds of fatty acids that form fat, which can be simply divided into saturated fatty acids and unsaturated fatty acids. It is generally believed that saturated fatty acids can promote the occurrence of atherosclerosis, while unsaturated fatty acids can prevent it.

In fact, there are dozens of food fatty acids, some of which participate in the formation of human tissue structure, some participate in the metabolic process, and some can regulate human physiological and biochemical reactions, all of which have certain effects on the human body. It is unscientific to evaluate them simply by "good" and "bad".

For example, we often regard cholesterol as a substance harmful to health, but cholesterol is an important substance for synthesizing bile, adrenocortical hormone, sex hormone and vitamin D, and only excessive cholesterol will cause harm to human body; However, we believe that DHA and EPA are beneficial to lowering blood lipids, but excessive amounts are also dangerous. Therefore, only a reasonable and balanced intake of various fatty acids is the guarantee of health.

Reasonable and balanced intake of fatty acids mainly means that the proportion of saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids in dietary fatty acids should be appropriate, and the proportion of n-6 and n-3 in polyunsaturated fatty acids should also be appropriate. The main way for people to ingest fatty acids is (1) to eat animal foods. Most of the fatty acids in animal foods are saturated fatty acids except fish. (2) Vegetable oil: The fatty acids in vegetable oil are mainly unsaturated fatty acids.

(3) complementary food: nuts such as walnuts, peanuts, melon seeds and fish containing EPA and DHA. In addition, other foods also contain a small amount of fatty acids.

In daily life, the intake of animal fat and other foods is generally fixed, while the types and consumption of plant fat are easily changed. Therefore, maintaining fatty acid balance can be achieved by adjusting vegetable oil. Vegetable oil is the main source of unsaturated fatty acids, but the fatty acid composition and proportion of each vegetable oil are different, and some of them are far from each other.

Consumers can alternately eat several kinds of vegetable oils for a period of time, so that the types and proportions of fatty acids ingested by human bodies are more in line with the needs of human health. However, alternating consumption can not accurately and quantitatively balance the intake of fatty acids.

According to the types and contents of fatty acids in China people's habitual diet, the producers of edible blended oil mix several kinds of vegetable oils, so that the fatty acids in vegetable oils and those in food tend to be more balanced after being matched, so as to meet the needs of human body.

5. What are the common sense of winter health care?

1, cold protection measures for general family rooms, the room temperature should be kept at 15QC-2oc.

In a low temperature environment, you should equip yourself with cold-proof clothes, hats, shoes, gloves, etc. Clothes, shoes, gloves, etc. Avoid dampness and keep it dry.

Fresh vegetables mixed with meat have better cold-proof effect.
