Six diets are appropriate. It should be early. After a night's sleep, the human stomach is empty, and we need some food to refresh ourselves in the morning, so we should have breakfast early. It should be delayed. Chewing slowly is good for digestion, and wolfing down will increase the burden on the stomach. It should be less. Although the nutrition needed by human body comes from diet, excessive eating can also damage digestive organs such as gastrointestinal tract. The right light Five flavors of diet should not be partial, and eating more light flavors is good for your health. It should be warm. The stomach likes warmth but hates cold. Diet should be warm but not cold, which is beneficial to the digestion and absorption of food by the stomach. It should be soft. Hard food is the most difficult to digest, while half-cooked meat will hurt the stomach, especially for people with bad stomach and old age, who are very prone to illness. Therefore, cooking, drinking and cooking must be cooked. Drink soup before meals. The dining habit of China people is to eat first, and then drink some vegetable soup. The western dining habit is to drink some soup (bread, etc.) before eating. ). Which of these two different dining habits is scientific and reasonable? From a scientific and healthy point of view, it is better to drink some soup before eating. Because people eat it immediately when they feel hungry, it is more irritating to the stomach and prone to stomach problems or indigestion for a long time. If you drink some soup before eating, just like doing preparatory activities before exercise, you can make the whole digestive organs active and make the digestive glands secrete enough digestive juice to get ready for eating. This will reduce the stimulation of fasting and help protect the stomach. Eat standing up. Medical scientists' research on the dining posture of different nationalities in the world shows that standing posture is the most scientific, sitting posture is the second, and squatting posture is the least scientific. This is because when squatting, the legs and abdomen are compressed, the blood is blocked, and the blood volume is reduced, thus affecting the blood supply to the stomach. When eating, it is precisely when the stomach needs fresh blood most, and some stomach diseases may be related to the squatting posture. When people eat, they mostly sit, mainly because they are tired from work, but they sit too much. Talk over dinner. Traditional habits believe that it is not appropriate to talk and laugh when eating, otherwise it is not conducive to digestion and absorption. Now, some health care experts think that about 30 minutes for lunch is appropriate. Chatting while eating during this time can let diners exchange feelings, relieve troubles and let the stomach digest food normally. The reason is that a happy mood can not only stimulate appetite, but also excite the central nervous system, thus promoting the secretion of digestive juice and making the gastrointestinal tract in the best digestive state. Love to eat hard food. Bitter food contains not only inorganic compounds, alkaloids and terpenoid hydrocarbons, but also some sugars and amino acids. Amino acids in bitter food are essential substances for human growth, health and longevity. Bitterness can also regulate the function of the nervous system, help people relax from the tense psychological state, and relieve the bad emotions caused by fatigue and boredom. Bitter foods such as bitter gourd, coffee, bitter herbs, arrowhead, tea, chocolate and beer contain vitamin B 17, which has a strong ability to kill cancer cells. Balanced nutrition. Not picky about food, not partial eclipse. Fruit should be eaten between meals; Drink soup before meals; Cucumber vegetables should be eaten alone. Three meals are different. Eat well early, at noon and at dinner. Hasty brunch and hearty dinner make people obese, accounting for 67%. Breakfast with low sugar, low fat and high protein is better. The same is true for lunch, because eating high protein such as chicken or fish at lunch can fill the blood with amino acids, including tyrosine, which can be transformed into chemicals that wake up the brain through the blood-brain barrier; Another key nutrient that can cross the blood-brain barrier is choline, which is found in fish, meat, egg yolk, bean products, oatmeal, rice, peanuts and peach kernels. Choline is the chemical precursor of brain neurotransmitter acetylcholine, which plays a major role in memory. High carbohydrate is more suitable for dinner. It feels good. Good mood when eating, increased appetite, good blood circulation, strong digestive function of gastrointestinal tract and enhanced immunity; If you feel depressed when eating, it will affect your appetite, affect the normal circulation of blood, reduce the function of the whole digestive system and reduce people's immunity. Pay attention to hygiene. Wash your hands before meals and don't eat rotten food. Chew slowly. Chewing can grind food into small pieces and mix with saliva to swallow. At the same time, chewing can also reflect the secretion of digestive juices such as saliva, gastric juice and pancreatic juice, which provides favorable conditions for further digestion of food. Time and quantity. Eating regularly and quantitatively can make the gastrointestinal tract peristalsis and rest regularly, thus increasing the digestion and absorption rate of food, keeping the function of the gastrointestinal tract in good condition and reducing the occurrence of gastrointestinal diseases. Eat less and eat more. Eat less, the concentration of sugar in the blood is low, the body secretes less insulin, the cholesterol level is reduced, and the body fat is also reduced; However, it should be noted that no matter how many meals you eat, the total calories should not exceed the sum of three meals a day. Diet. Food restriction can not only reduce the burden on the gastrointestinal tract, but also stimulate the autonomic nervous system, endocrine system and immune system in a semi-starvation state, thus mobilizing the regulatory function of the human body, stabilizing the circulation balance in the body, enhancing immunity, balancing the excitement and inhibition of the nervous system, and helping to improve people's disease resistance. Diet and daily life are indispensable to everyone's life. Food is the most important thing for people, and diet is the basic condition for human life. In addition to paying attention to nutrition and reasonable collocation, we should also pay attention to the right amount in diet. More than 2000 years ago, Kan Zi pointed out: "A frugal diet is good for health and life. If you don't eat frugally, you will lose your life. " Festivals are temperance, temperance. Three meals a day should be regularly quantified in time and quantity. Because breakfast, lunch and dinner have become people's eating habits, conditioned reflex will occur at this time, which will strengthen the secretion of digestive juice and digestive enzymes by digestive veins, delay the time of eating, or overeat when you are hungry, which will cause digestive system disorder, damage the stomach and spleen, and suffer from incurable gastrointestinal diseases. /kloc-in the middle of 0/7th century, Thomas Pell, an English farmer, lived 132 years. The king called him into the court and gave him a banquet. He died of overeating. At that time, Harvey, a famous medical scientist, dissected him and found that his body and internal organs were not aging. If he hadn't eaten too much, he would still be alive now. Now the fast-paced lifestyle, eating time will be more compact, but the timing and amount can be completely controlled by yourself. Sleep is a very important physiological phenomenon in life. Sleep is a protective inhibition of cerebral cortex cells, preventing brain cells from being overtired, and it is an inevitable content of life to eliminate mental and physical fatigue and regulate the body. Life is spent in sleep13 of the time. Waking and sleeping, day and night are the basic laws of biology and nature, forming the biological clock phenomenon of human body. Long-term lack of sleep will disrupt the biological laws of the human body, people's physiological functions will be chaotic, the nervous system will be disordered, and the ability to learn and work will decline. In severe cases, it will lead to systemic diseases, such as neurasthenia, weakened digestive function and other cardiovascular diseases. Professor Seto in Japan once published a document that students staying up late is closely related to illness: about 30% of students sleep at 0: 00, 75% sleep at 0: 00 to 2: 00, and 95% of students who don't sleep after 2: 00 feel unwell. "Sleeping and eating are two important tasks of health preservation" has long been recognized by the ancients. Sleep is better than prescription. Like nutrition, it is an important means to improve physical fitness and ensure health. The ancients said to teenagers that "people who can sleep can eat and grow", and said to people with weak constitution that "Huashan Chu Shi is like a guest, and you can find a prescription for sleeping without looking for a fairy". It can be seen that sleep plays a very important role in maintaining a strong body and recovering from diseases for teenagers or normal people in the growth and development stage. The length of sleep varies from person to person, usually around 8 hours. Teenagers are relatively longer than adults, older people are more than adults, and women are more than men. Everyone's study and work are not an old-fashioned model, which should be adjusted according to the specific conditions of study and work. For example, when students review for the exam or concentrate on thinking about a problem, the cerebral cortex will get excited and sleepy. After a stressful life, they should actively strive for rest, make up for lack of sleep, and readjust their body balance. Otherwise, the brain nerves will be in a state of excitement for a long time, affecting the overall function and damaging the body. Everything has a degree, and too little sleep hurts the spirit and physique; Too much sleep is also harmful to the body, which will make the sleep center in a state of fatigue inhibition, weaken the metabolic function of the body and the functions of various organs, and at the same time make people lazy, slow-thinking and weak. Traditional Chinese medicine has a saying that "long lying down hurts the qi" for normal people. Statistics show that the mortality rate of adults who sleep more than 10 hours every night is 80% higher than that of those who sleep for 7-8 hours, and the mortality rate of those who sleep less than 4 hours is 80% higher than that of those who sleep for 7-8 hours. It can be seen that only proper sleep can be beneficial to health and improve physical fitness. There are over 200 centenarians in Dalian. What is the way for centenarians to be healthy? One of the "Tao": homology and diversification of medicine and food. These centenarians never tire of eating. They have developed the habit of coarse grains, vegetables and vegetarianism since childhood. At the same time, many centenarians like to eat wild vegetables, small fish and shrimp, and eat "whole fish" (with a head and a tail). Many active substances are in the head and tail of small fish and shrimp, which makes them reduce or develop cardiovascular and cerebrovascular diseases in the later stage. The second is a reasonable diet. Many centenarians drink no less than 1000 ml of water every day. Tian Riying, 107 years old, eats a steamed carrot every day and never gets sick. The third is careful modulation. The nutrition of food has a lot to do with the preparation method. When they eat garlic, they must mash it and combine it with oxygen to produce allicin, so that garlic can become the king of cancer prevention. The second "Tao": daily life is regular. These centenarians arrange their daily life according to the biological clock, let them get up at dawn and rest at sunset; Eat on time and change clothes on time; Drink plenty of water and defecate regularly. Some centenarians also have a set of experience in preventing sudden cardiovascular and cerebrovascular diseases. One is to drink water in balance day and night to reduce blood viscosity; The second is to massage when getting up, that is, massage the abdomen before getting up; Massage the waist after sitting up; Put your legs in front of the bed and beat your back. This can reduce the incidence of cardiovascular and cerebrovascular diseases and is conducive to health and longevity. The third way: combine work and rest. These centenarians are generally hard-working and their livelihood is based on labor. Ganjingzi District/KLOC-Ma Yongyun, a 0/04-year-old man, has a clear head and steady steps, and is still engaged in some housework. The old man said, "I chased the sea for twenty years, planted vegetables for twenty years and sewed rags for thirty years." Su Lianhua, a 0/04-year-old woman from Wafangdian/KLOC, said that her longevity experience was "walking often". The doctor examined her body and thought that there was nothing wrong with her internal organs, and her heart beat was steady and strong, which was better than that of young people.
