Next, let's talk about the bad influence of high technology on our human beings. The development of high technology has brought unprecedented benefits to our lives, but it has also brought us great sadness. Chemical products, chemicals and chemical wastes are all endangering our health. Harmful gases such as sulfide and carbide after automobile fuel combustion are constantly enriching our air. Due to various industrial pollutants and people's improper disposal of garbage, it is also polluting the land and drinking water on which we human beings depend. However, the outbreak of war, the arms race between countries and the development of nuclear weapons have also caused us great potential nuclear radiation hazards. Air pollution, food pollution, water and soil pollution and other unfavorable factors are restricting our human physical and mental health. Although modern medical technology has made great progress, it can not completely solve the influence of many unfavorable factors brought by the development of human high technology.
Contemporary people have been obsessed with many of their own diseases, such as cardiovascular disease, cancer, unexplained, autoimmune decline. Doesn't it mean that the human body is suffering from a great impact of various toxic pollutants? Moreover, all kinds of skin diseases, early-onset cardiovascular diseases and cancer caused by harmful pollutants are not all like this? Appear in our bodies at a high growth rate? Nowadays, modern medical technology is also developing vigorously, and the life span of human beings is also extending constantly, but this extension of life is bought with our sick bodies. If you don't believe me, you can do an investigation. As early as the 1980s, people's healthy life expectancy was longer than that of our modern people. At that time, people's serious illness mostly occurred in human heredity and the erosion of human body by bacteria or viruses, and there were few causes caused by environmental pollution. Nowadays, cardiovascular diseases, cancers caused by environmental pollution, unexplained diseases, skin diseases and premature decline in health are all serious consequences brought about by the rapid development of modern science and technology.
Now, even if your medicine is developed and your technology is perfect, you can't solve the chronic diseases caused by toxic substances formed in various modern industries. If we want to continue the normal reproduction of human beings, we must maintain the continuation of our own lives through modern medical means and drugs. I don't think this is what we humans want. You can analyze how our human mind can be so ignorant. Who is digging graves for mankind? Air pollution, soil and water pollution and food pollution, coupled with the frequent occurrence of various natural disasters and man-made secondary disasters, have seriously damaged the natural biological chain. I don't need to say, can we still live a normal life in the face of the present situation of our human living space? I wonder what modern people are thinking. Strictly speaking, the unlimited exploitation and destruction of natural resources by human beings, the harmful substance rays of modern scientific and technological products, the cosmic hadron radiation caused by the hole in the ozone layer, the destruction of the ionosphere, the greenhouse effect and other natural ecological factors are not all the reasons for many problems brought about by the rapid development of human science. The more advanced the technology, the greater the damage to nature. How to return human beings to nature, protect the earth space on which human beings depend, maintain people's healthy physique, prolong people's healthy life and reduce the morbid period, we should ask ourselves, and time waits for no one! Longevity maintained by drugs is a morbid and unhealthy state, which brings too much psychological pressure to the elderly and often produces unbearable suicidal thoughts. It is better for human beings to return to nature and seek health and longevity, which will not drag down children and cause trouble. What a wonderful thing! My life is full. But this society is crazy! Crazy! I still want to advise you to stay away from genetically modified food and food contaminated by pesticides, and stay away from the heavily polluted metropolis. We can eat more green food produced and sold by farmers every day, so that people can have a healthy, happy and happy old age, and don't let sick and annoying old people interfere with their children's normal life. In addition, the elderly can also do some unfinished work and ideals when they were young. Moreover, people living in big cities should often go for a walk in the countryside, breathe more fresh air without any pollution, eat more farmhouse meals, and stay away from the sub-health and morbid health caused by pollution. Only in this way can we become the ultimate goal of human choice.
In view of the above, if we slow down the exploitation of natural resources, speed up the development of bioenergy, light energy, wind energy and tidal energy, slow down the pace of transportation, and restrict production of chemical industrial products and other related industries harmful to human beings, then our human society will be even better. However, this is only a suggestion, and the main decisive factors should be irresponsible politicians all over the world and laws and regulations of human society, and only they are the masters of prolonging our human health. First, low-sodium diet, I said "low sodium" instead of "low salt", because sodium-containing food is far more than salt (sodium chloride). On the one hand, in addition to taking less salt from salt cans, we should also pay attention to the salt contained in soy sauce, pickles, preserved eggs and dried noodles. In addition, monosodium glutamate and sodium glutamate contained in soy sauce are another kind of "sodium salt", which also has the effect of raising blood pressure. The World Health Organization recently suggested that the daily salt intake of healthy adults is 5 grams, while for patients with hypertension, our recommended intake is 3 grams.
2. Dieting: For every weight gain 1%, blood pressure will increase by about 5-8 mm Hg. Controlling the intake of rice, flour, sugar and other calories, regular exercise and controlling the weight at an ideal level are the basis for controlling hypertension. In addition, dieting also refers to limiting the intake of saturated fatty acids and cholesterol, eating less animal fat and limiting the amount of red meat. Coarse grains such as sorghum, sweet potato and corn can help the excretion of cholesterol in the body, which is also a good choice. Dieting is not only to reduce food, but also to eat more plant protein and fish, which is effective in preventing and treating vascular complications.
Third, eat more foods containing potassium. Potassium and sodium are like sitting on a seesaw. When the potassium content is high, it can promote the elimination of sodium, thus reducing the content of sodium in the body, which also reduces the absorption of excessive water by sodium into blood vessels and plays a role in lowering blood pressure. Oranges, oranges, bananas, potatoes, celery, mushrooms and bean products are rich in potassium. Everyone knows that eating well is good, but there are many things in life that will hurt you inadvertently. Let's take a look at the following 2 1 most harmful eating habits.
1. Eat more fiber and reduce calcium! Excessive dietary fiber increases the speed of food passing through the intestine and reduces the absorption rate of calcium; The research shows that when the diet of two adults changes from refined bread with low fiber content to coarse bread with high fiber content, calcium (magnesium, zinc and phosphorus) is negatively balanced.
2. Overeating meat and eggs leads to iron "out"! Now most children like to eat all kinds of meat, but they don't like vegetables and fruits. Parents also think that eating more meat, fish and eggs rich in iron and zinc doesn't matter. As a result, the child not only "jumped" in weight, but also suffered from iron deficiency anemia as soon as he was examined.
Because most of the iron in lean meat, animal viscera and egg yolk is trivalent iron, it is not easy to be absorbed by the human body. Only in the presence of vitamin C and sour substances (rich in organic acids such as malic acid, tartaric acid and citric acid) can it be fully absorbed and utilized by the human body. Vegetables and fruits (such as kiwi fruit, lemon, fresh jujube, wild jujube, orange, raspberry and apple) are the most abundant in vitamin C and sour substances. If you only eat lean meat, animal offal, egg yolk and other foods, but don't eat or eat less vegetables and fruits, the iron in these foods can't be absorbed and utilized by the human body, resulting in extremely high nutritional cost and iron deficiency anemia.
3. calcium and phosphorus imbalance "drives away" calcium! The imbalance between calcium and phosphorus is the chief culprit leading to calcium deficiency. Under normal circumstances, the ratio of calcium and phosphorus in human body is 2∶ 1. However, in real life, people eat too much phosphorus-containing food, such as carbonated drinks, cola, coffee, hamburgers, pizza, wheat germ, animal liver, French fries and so on. However, the intake of phosphorus often exceeds 10 times of calcium, making the ratio of calcium to phosphorus as high as 1:.
4. Drugs lead to nutrient loss! Most female friends who use birth control pills may not know that birth control pills will hinder the effects of vitamin B6, B 12, folic acid and vitamin C, and lutein in birth control pills will hinder the effects of vitamin B6 and the absorption of folic acid. Aspirin will triple the amount of vitamin C excreted from the body. A large amount of vitamin C supplementation will "drive away" folic acid in the body. Antiepileptic drugs can also hinder the absorption of folic acid.
5. Smoking, drinking and nutrition slip away! Long-term smoking and drinking destroy the vitamins necessary to maintain good health. Smoking destroys vitamin C, a nutrient that can prevent cancer and heart disease. Smoking half a pack of cigarettes a day will destroy 25 ~ 100 mg of vitamin c in the body; Drink more than one cocktail every day, and enjoy the spirits at the cost of consuming vitamins B 1, B6 and folic acid. It is also quite common for alcoholics to lack vitamin B 1.
6.VitC effervescent, can I use it? Miss Li, who works in the company, pays great attention to nutrition. After every meal, she pours a large glass of vitamin C-rich drinks (such as Jane or vitamin C effervescent tablets) with boiling water. But in recent days, she was afraid to brush her teeth and came to consult. It stands to reason that Guozhen or vitamin C effervescent tablets are rich in vitamin C, why are there symptoms of gingival bleeding?
It turns out that vitamin C is water-soluble and unstable. Taking water above 80℃ will seriously destroy vitamin C, not to mention 100℃ boiled water. Use boiled water to make drinks rich in vitamin C, and there is little vitamin C left in the stomach. Therefore, warm water should be used instead of boiled water to make drinks rich in vitamin C.
7. Supplement calcium without magnesium, and regret after eating! When people supplement calcium, they only pay attention to vitamin D, but they often don't know how to supplement magnesium. Like twin brothers, calcium and magnesium always appear in pairs, and the ratio of calcium and magnesium is 2: 1, which is most beneficial to the absorption and utilization of calcium. Therefore, when supplementing calcium, remember not to forget to supplement magnesium. Foods rich in magnesium include nuts (such as almonds, cashews and peanuts), soybeans, melon seeds (sunflower seeds and pumpkin seeds), cereals (especially rye, millet and barley) and seafood (tuna, salmon, mackerel, shrimp and lobster).
8. Big fish and big meat "eat" calcium! A high protein diet is the cause of osteoporosis. Someone has done such an experiment: A: Taking 80 grams of protein every day will lead to 37 mg of calcium loss; B: Taking 240 grams of protein every day and supplementing 1400 mg of calcium will lead to the loss of 137 mg of calcium. This shows that extra calcium supplementation can not prevent calcium loss caused by high protein.
This is because excessive intake of acidic foods such as big fish and big meat can easily lead to acidic constitution. But the human body can't bear the drastic change of pH value in blood, so the body will neutralize it with two main alkaline substances-sodium and calcium. When the sodium in the body is used up, the calcium in the body will be activated, so excessive intake of big fish and meat without paying attention to the acid-base balance will lead to a large loss of calcium.
This is also the reason why those rich people who often eat banquets (the dietary characteristics are: more meat, more wine, more oil and less food) often feel tired, dizzy and exhausted! The second is to catch up with the fashionable diseases of metabolic syndrome (hypertension, hyperlipidemia, diabetes, obesity, fatty liver, gout, etc.). ).
9. carbonated drinks, don't drink too much! Nowadays, children like to drink drinks as water when eating, such as cola and juice drinks. The carbonic acid in these carbonated drinks will form insoluble calcium carbonate with calcium in the body, which will take away the calcium in the food you eat, leading to calcium loss and calcium deficiency symptoms.
10. Eggs are eaten in various ways and absorbed differently! In terms of nutrient absorption and digestibility, boiled eggs are 100%, scrambled eggs are 97%, tender fried eggs are 98%, old fried eggs are 8 1. 1%, boiled eggs with milk are 92.5%, and raw eggs are 30% ~ 50%. From this point of view, boiled eggs are the best way to eat, but pay attention to chewing slowly, otherwise it will affect absorption and digestion. But for children and the elderly, steamed egg soup and egg drop soup are the most suitable, because both methods can decompose protein and are easy to digest and absorb.
1 1. Turn disadvantages into advantages and improve efficiency! For example, vegetables containing more oxalic acid (spinach, amaranth, winter bamboo shoots, coriander and cauliflower) should be blanched with boiling water before frying to remove oxalic acid, avoid the combination of oxalic acid and calcium to form insoluble calcium oxalate, and improve the absorption and utilization rate of calcium; Phytic acid existing in soybean, wheat and grain hulls is easy to combine with calcium and zinc to form insoluble phytate. Germination, fermentation, soaking and other methods can be used to activate the activity of phytic acid decomposing enzyme to decompose phytic acid, thus improving the digestion and absorption rate of calcium and zinc in human body. In addition, because flour contains more phytic acid, it should be fermented as much as possible when making pasta. After flour fermentation, the activity of phytic acid decomposing enzyme is enhanced, which can decompose phytic acid in flour and promote the digestion and absorption of calcium and zinc in pasta.
12. There is a lot of knowledge about nutrition and catering! For example, the dish "Youganjian" is made of liver as the main ingredient, cucumber as the auxiliary material and persimmon pepper as the auxiliary material. In contrast, persimmon pepper is much more scientific than cucumber! Because the liver is rich in trace elements of iron and zinc, there is more vitamin C in persimmon pepper than in cucumber. Vitamin C can promote the transformation of trivalent iron in the liver into divalent iron, which is beneficial to the body to better absorb iron and zinc! Another example is stewed fish with tofu. Tofu contains vitamin D and tofu is rich in calcium. Vitamin D can promote the absorption of calcium and greatly improve the utilization rate of calcium in tofu. In addition, the staple food pays attention to the collocation of cereals and beans, which not only complements amino acids to the most reasonable level, but also promotes the absorption of calcium.
13. Should we have a light meal before going to bed? Promote growth! A study shows that during sleep, the human body is constantly eliminating old bone tissue, and this process is the fastest at around 3 am. Therefore, adding a cup of yogurt before going to bed can supplement the calcium source in time to ensure that your calcium index is more stable at night.
14. The longer the bean sprouts, the better! Aunt Zhang, who lives next door, likes to buy long bean sprouts. She thinks long bean sprouts are the most nutritious! Actually, it is not! After soybean germination, the free amino acids, total free amino acids and reduced vitamin C, which promoted the absorption of calcium, zinc and iron, increased significantly. In addition, phytase activity is increasing and phytic acid is continuously hydrolyzed during soybean germination, which leads to a downward trend of phytic acid, which is the main inhibitor of calcium, zinc and iron absorption, and is 40% lower than that in soybean or tofu, thus greatly improving the bioavailability of calcium, zinc and iron in germinated soybean. Bean sprouts with 3-4 days (about 4-5 cm long) have the best nutrition.
15. It seems like a lot, but it is actually very few! Milk has high calcium content and good absorption and utilization rate, and is recognized as an excellent natural calcium-supplemented food source all over the world. But drinking milk is very particular! It seems that you eat a lot of milk, but you can't really absorb much! Many people will have some discomfort after drinking milk or dairy products, such as farting, flatulence, abdominal cramps, diarrhea and so on. Recently, I learned from the International Dairy Congress that 70% of Asians do not absorb lactose, and 75 ~ 100% of China people are lactose intolerant, such as 69.4% in Beijing, 75.8% in Shanghai and 68.9% in Harbin.
16. Drinking milk for the elderly is not worth the candle! Milk contains 5% lactose, which is decomposed into galactose under the action of lactase, which is easy to deposit on the lens of the elderly, resulting in decreased lens transparency and senile cataract. Old people can choose foods with high calcium content such as dried shrimps, dried shrimps, fish, shellfish, eggs, meat and bones, kelp and snails, celery, bean products, sesame seeds, red dates, black fungus, etc. Natural foods are the best.
17. Drinking milk on an empty stomach Some people like to drink a glass of milk on an empty stomach for breakfast in the morning, but I don't know that this is a bad practice. After a night of digestion and absorption, the gastrointestinal tract is almost empty. If you get up in the morning and drink milk on an empty stomach, the milk will be discharged along the empty gastrointestinal tract before it is fully absorbed by the body, resulting in a great waste of nutrition. Therefore, it is best to eat some biscuits, bread or bread rolls, steamed bread and other carbohydrates when drinking milk, and never drink milk on an empty stomach.
18. Eat milk and chocolate together! Some people like to add chocolate to milk to get rid of the strange smell in milk. Actually, this is unscientific. Milk is rich in calcium and protein, while chocolate contains oxalic acid. Milk and chocolate are eaten together, and calcium in milk can easily make oxalic acid in chocolate form water-insoluble precipitate-calcium oxalate. People can't absorb it, and after a long time, they will have dry hair, loose bowels, calcium deficiency and slow growth. So the time to drink milk and eat chocolate should be separated.
19. Raw carrots are not absorbed! It is often seen that some old women give their children some raw carrots. They say that this can not only grind teeth, but also supplement "vitamins", which is the most typical nutritional misunderstanding in our lives. It is unscientific to eat carrots raw. The digestibility of carotene was 10%, 30% and 90% when carrots were eaten raw, cooked with little oil and cooked with enough oil, respectively. It can be seen that the digestion and absorption rate of carotene in the body is directly proportional to the proportion of oil; Carrots cooked with edible oil have higher nutritional value than raw carrots.
20. "Skin" is very important. It is a pity to abandon it! Eggplant, blueberry and grape skin contain a lot of polyphenols. Polyphenols are an antioxidant, which can prevent free radical oxidation and delay aging. It's a pity to eat without skin! In addition, peeling tomatoes will make lycopene, a very important antioxidant in tomatoes, easily lose with the juice, which is not conducive to maintaining health.
2 1. The world's top ten junk foods announced by the World Health Organization: fried food, pickled food, processed meat food (ham sausage, dried meat, floss, etc. ), biscuits (excluding low-temperature baking and graham crackers), soft drinks and cola foods, instant noodles (mainly instant noodles and puffed foods), canned food, preserved fruits such as preserved plum, and frozen.
