1. Eat less salt. The World Health Organization suggested that the appropriate daily intake of salt was 6 grams, while the actual daily intake per capita in China was more than 13 grams, which exceeded the standard amount 1 times.

2. What do you eat in your heart? Vitamin C has the function of balancing psychological stress. When under strong psychological pressure, the body will consume 8 times more vitamin C than usual, so try to eat more foods rich in vitamin C. Such as stir-fried flowers, Chinese cabbage, spinach, sesame seeds, fruits and the like. People with high work pressure will have unexpected effects if they take vitamin C tablets.

What do you eat when you are exhausted? Can you eat some peanuts, nuts, nuts? Cashew nuts, walnuts and other dried fruits. This snack has a magical effect on restoring physical fitness. Because they are rich in protein, vitamin B and vitamin E, calcium, iron and vegetable fat, but they do not contain cholesterol.

In addition, germ can also make people rejuvenate. Clam soup, shredded green peppers, cold dishes, sesame seeds, strawberries and other foods are rich in protein, with moderate calories, which can protect and strengthen the liver. You might as well eat more.

Bad temper. What? If calcium is added to the food of unhealthy teenagers, it can change their aggressiveness and destructiveness. Calcium has a sedative effect. Dairy products such as milk, lactic acid and cheese, as well as dried fish, are rich in calcium.

What can I eat if I can't drink well? 1 Eating more high-protein foods such as fish, meat, eggs, tofu and cheese can prevent drunkenness, and there are supply camps? The effect of raising. In addition, cows will form a jealous film on the stomach wall, so drinking a cup before drinking can not only protect the stomach, but also reduce the degree of alcohol fermentation.

What to eat after continuous overtime? The ideal midnight snack should be digestible.

Foods rich in vitamins and protein without too many calories. But it also depends. If you eat supper after work, you should choose foods that are easy to digest and will not increase the burden on your stomach, such as vegetable porridge, egg drop soup, and blunt rolls.

Never eat a big bowl of noodles before going to bed and fall asleep.

What's the hurry for breakfast? If you don't eat breakfast, your blood sugar will inevitably drop, and you can't concentrate all morning, so you are sleepy and your work efficiency is extremely poor.

So, if you want to sleep for a while and have no time to eat breakfast, you should at least drink some milk, eat some biscuits and take some multivitamins.

3, how to eat dinner, eat dinner early.

Eating dinner early is a good health care policy recommended by medical experts. Studies have shown that eating early at dinner can greatly reduce the incidence of urinary calculi. The peak of calcium excretion is usually 4-5 hours after meals. If you eat dinner too late, when the peak of calcium excretion comes, people have gone to bed and fallen asleep, and urine will remain in the urinary tract such as ureter, bladder and urethra, which can not be excreted in time, resulting in an increase in calcium in urine and easy deposition to form small crystals. Over time, it will gradually expand and form stones. So it is more appropriate to have dinner around 6 pm.

Eat vegetarian food for dinner.

Dinner must be vegetarian, with carbohydrate-rich food as the main food, while in protein, the less fat you eat, the better. However, in real life, because most families have enough time to prepare dinner and eat a lot, it is not good for their health. According to related research reports, eating a large number of high-protein foods such as meat, eggs and milk at dinner will increase the calcium content in urine. On the one hand, it will reduce the storage of calcium in the body and induce childhood diseases, myopia and osteoporosis in middle-aged and elderly people. On the other hand, high calcium concentration in urine will greatly increase the possibility of urinary calculi. In addition, if protein is ingested too much, it will stay in the intestine and deteriorate, producing toxic substances such as ammonia and hydrogen sulfide, stimulating the intestinal wall and inducing cancer.

If you eat too much fat, your blood lipids will increase. According to research data, people who often eat meat for dinner have 2-3 times higher blood lipids than vegetarians.

Carbohydrate can produce more serotonin in the human body, which plays a role in calming the nerves and is especially beneficial to insomnia.

Eat less dinner than breakfast and Chinese food. Eating too much dinner will lead to an increase in cholesterol, stimulate the liver to produce more low-density and very low-density lipoproteins, and induce arteriosclerosis; Long-term overeating at dinner and repeated stimulation of insulin secretion often lead to premature failure of insulin B cells, thus laying the bane of diabetes.

In addition, overeating at dinner will swell the stomach and oppress the surrounding organs. After meals, the intense work of the stomach, intestine, liver, gallbladder, pancreas and other organs will send information to the brain, which will make the brain active and spread to other parts of the cerebral cortex, causing insomnia.

4, be careful, don't put yourself? Eat? In our daily life when we are old, some people especially like to eat cured meat, vegetables or pickled fish products. Some people, especially some men, often indulge in wine in hotels. Don't you know that these bad habits will eat you up? Old? Yes 3 Alcohol and alcoholic beverages Drinking a lot or often in life will make the liver inflamed and swollen due to alcoholism, leading to male sperm malformation, sexual dysfunction and impotence. Women who often drink alcohol or alcoholic beverages will have symptoms such as irregular menstruation, ovulation cessation and decreased sexual desire, which will lead to signs of premature aging.

Mildew food Generally speaking, middle-aged women are good housekeepers, and rice noodles, soybean oil, peanuts and frozen meat at home are still reluctant to throw away after deterioration. You don't know that moldy food will produce a lot of bacteria and aflatoxin when it is moldy, and aflatoxin is a carcinogen. People who eat moldy food may have diarrhea, vomiting and dizziness, and may also cause cancer, teratogenesis and premature aging.

Pickled food Pickled food belongs to high-salt food. People who eat too much can easily induce cardiovascular and cerebrovascular diseases and make the body enter a premature aging state.

Scale in daily life, some people do not pay attention to cleaning tea sets or utensils, which makes scale deposit after long-term use. Scale contains mercury, arsenic, aluminum and other harmful metal elements. If it remains in the human body for a long time, it will damage human organs. Regular use of calibrated vessels to drink water will cause systemic diseases such as digestion, nerves, urine and hematopoiesis, leading to aging.

Expired instant noodles, biscuits, fried foods, cooking oil left after frying, dried fish and bacon exposed to the sun for a long time, biscuits, instant noodles and oils stored for a long time, especially spicy foods, all contain lipid peroxide. Lipid peroxides are peroxides of unsaturated fatty acids. Studies have found that lipid peroxide, after entering the human body, has a destructive effect on the acidic system and vitamins in the body, prompting people to age ahead of time.

Although there are many reasons for premature aging, due to bad living habits, intake of four substances promoting premature aging is one of the important reasons that cannot be underestimated.

5. How to eat lightly, lightly, and then lightly? Nutritionists suggest that efforts should be made to change? Salty is fresh? The concept of diet, and strive to achieve a family of three with no more than 500 grams of salt per month.

It is best to drink a bottle of milk every day. Milk is rich in nutrition and calcium, and fresh milk (227 g) contains about 250 mg of calcium.

An egg a day. Eggs are a kind of natural food with high nutritional value. Egg protein can provide extremely rich essential amino acids, and its composition ratio is very suitable for human needs. Most of the fat in eggs is in the yolk, which is dispersed into fine particles and easily absorbed.

There is at least one meal of fish meal on the dining table every week. Researchers have found that fish are rich in N-3 series unsaturated fatty acids, in which DHA and other diluted fatty acids can take cholesterol away from blood vessels after combining with cholesterol in blood.

Chicken and duck instead of pork. Scientific analysis shows that every 100g of chicken contains protein 16.6g and fat 14. 1g, while every 100g of pork only contains protein 1.6g, and the fat content is 89.5g.

Increase the intake of soy products. Soybean is rich in nutrition and can be called a flower in nutritious food. It is particularly worth mentioning that the content of protein in soybean is 2-3 times that of pork, 5.2 times that of eggs and 12 times that of milk. According to Japanese scholars, soy protein inhibitors can prevent gastric cancer.

Everyone had better eat 500 grams of vegetables every day. Some people think that vegetables are low-grade food, but they are not.

Take garlic as an example, it can inhibit or kill many kinds of bacteria, and also has the functions of anti-cancer, lipid-lowering, detoxification and hemostasis, so it can be eaten and used medicinally.

Mushroom food is included in the diet. Mushroom foods such as Lentinus edodes, Lentinus edodes, Lentinus edodes and Auricularia auricula are not only delicious, but also contain more protein than ordinary vegetables, and have an appropriate proportion of essential amino acids and various trace elements, so they are recommended as nutritious foods.

Lentinus edodes contains 18 kinds of amino acids, more than 30 kinds of enzymes, vitamin B 1 and vitamins A and D, which can improve the body's inhibitory effect on malignant tumors. In addition, Lentinus edodes also contains mycelium fluid and lentinan, which not only has good anti-tumor effect, but also can induce the occurrence of interferon in human body, thus improving the immunity of the body and playing an antiviral role. In addition, the nucleic acid in Lentinus edodes can inhibit cholesterol in serum and liver, prevent and treat hyperlipidemia, and then play a role in preventing and treating coronary heart disease. Mushrooms and shiitake mushrooms have similar functions, and long-term consumption can play a good health care role. Auricularia auricula is also a kind of mushroom, which is called? Meat in a vegetarian diet? This is a good health food. Long-term consumption of auricularia auricula can prevent coronary heart disease and atherosclerosis.

Have a good meal. Foreign medical experts believe that the traditional diet in China is the best diet structure to prevent atherosclerosis. Domestic nutritionists have repeatedly called for maintaining the basic characteristics of China's diet, which is mainly plant food, supplemented by animal food, and the energy source is mainly grain, so as to avoid the disadvantages of poor quantity and quality of protein.

6. The diet should be reasonable. What is a dietary balance and how to achieve this standard? The so-called dietary balance refers to the complete variety, sufficient quantity and appropriate proportion of nutrients contained in the diet, namely:

Amino acid balance, heat and nutrition balance, acid-base balance and the intake of various nutrients should also be balanced, and only in this way can the absorption and utilization of nutrients be facilitated.

As we all know, people divide essential foods into five categories in their daily lives. The first category is food, which is the main source of heat. Generally, light manual workers consume 300-500 grams per day, and the rest of the calories are supplied by non-staple food. Therefore, grain accounts for 60%-70% of the heat supply and about 32% of the total diet.

The second category is foods rich in animal protein, including lean meat, eggs, poultry and fish. Adults should take 70- 100g protein every day. According to research, the absorption rate of animal protein is higher than that of plant protein. The reasonable intake of protein should be animal protein 1/4, bean protein 1/4, and the remaining 2/4 is food supply. Therefore, experts suggest that each person should consume 50- 100g of poultry meat, 50g of fish and shrimp and 25-50g of eggs every day. This kind of food should account for 13% of the total diet.

The third category is beans, milk and products. Because beans are rich in protein, unsaturated fatty acids and lecithin, their protein amino acid composition is close to human needs. Each person should supplement 50 grams of beans and 100 grams of milk every day, accounting for 9.5% of the total.

The fourth category is vegetables and fruits, which are the main sources of vitamins, inorganic salts and dietary fiber, but there are many varieties of vegetables and their nutritional components are also very different.

For example, green leafy vegetables contain a lot of carotene, antacids and inorganic salts such as calcium and phosphorus; Root vegetables are rich in starch, protein and carotene; The carbohydrate, iron and thiamine in fresh bean vegetables are incomparable with other vegetables, so each person should consume 400-500 grams per day, and the green leafy vegetables should be kept above 1/2. Fresh fruit is a good source of ascorbic acid, which can provide a lot of inorganic salts such as protein, phosphorus and iron, so everyone should take 100-200g of fresh fruit every day. This kind of food should account for 40% of the total.

The fifth category is oil, which can supply heat, promote the absorption of fat-soluble vitamins and supply unsaturated fatty acids.

Vegetable oil contains higher essential fatty acids than animal oil, while animal oil contains more saturated fatty acids, and the melting point of fat is higher, so it is not easy for human body to digest and absorb, so eat less animal fat and more vegetable oil. Therefore, nutritionists suggest that the proportion of oil intake is saturated fatty acid, dilute unsaturated fatty acid and monoethylenically unsaturated fatty acid, each accounting for 1/3. You should consume 1g of oil per kilogram of body weight every day, accounting for about 1.5% of the total diet.

To sum up, long-term lack of any of the above five foods will affect your health. In order to maintain a balanced diet, people should not eat too much food every day, let alone overeat during festivals. If they really match the thickness, the meat will be good and the body will be more secure.

7. Misunderstanding of life Many people think that new tea leaves are bright in color, delicious in taste, refreshing, and drinking more is beneficial and harmless to the body. It's actually wrong. New tea leaves stored for less than a month contain more unoxidized phthalides, aldehydes and alcohols. Drinking more will stimulate the stomach, cause abdominal distension, abdominal pain and other symptoms, and aggravate the condition of patients with chronic gastritis.

Don't eat sauerkraut has been circulating? Is cancer related to sauerkraut? Therefore, people are afraid to eat sauerkraut. Sauerkraut is actually lactic acid crystal produced by lactic acid bacteria decomposing sugar in Chinese cabbage. Lactic acid is an organic acid, not a carcinogen. When absorbed by human body, it can stimulate appetite and promote digestion. At the same time, Chinese cabbage turns sour, and the nutrients are not easy to lose. Eating sauerkraut is beneficial to people. 8 Drinking milk on an empty stomach Many people drink milk in the morning, thinking that it can absorb all the nutrients. In fact, drinking milk on an empty stomach will soon be discharged into the large intestine through the stomach and small intestine, so that various nutrients will be excreted before digestion and absorption.

The correct way to drink milk is to eat something before drinking milk.

Boil milk for a long time. Some people boil milk for a long time, fearing that the bacteria in the milk will not die.

In fact, when milk encounters high temperature, it not only loses its fragrance, but also loses a lot of protein denaturation and vitamins. So boiling milk is limited to boiling.

After rice was exposed to insects, some people exposed it to the sun, thinking that it would kill Mi Chong or run away. In fact, not only the sun can't kill Mi Chong, but also the dried rice can produce insects and multiply faster.

Exercise on an empty stomach Many people are used to running on an empty stomach in the morning, thinking that this can not only absorb fresh air but also prevent obesity. But the energy source of fasting exercise mainly depends on fat dysplasia. At this time, the free fatty acids in the blood will increase. Fatty acids not only become the energy source of myocardial activity, but also become myocardial poisons in excess, which can cause various arrhythmia and even sudden death. Older people are at greater risk. It is reported that several joggers in the world are short-lived. Therefore, it is necessary to eat some food properly before running in the morning.

Many people think that spinach is rich in iron, and children are often given spinach to replenish blood. Some adults with anemia also regard spinach as a good blood tonic and often eat it. In fact, the iron content of spinach is not the highest, and it can't replenish blood. Because only 1% iron in spinach is absorbed by intestine, 90% iron is combined with oxalic acid, which is not only difficult to absorb, but also affects the absorption and utilization of iron by human body. 9 Fat people on an empty stomach are afraid that fat meat will induce hypertension, coronary heart disease, hyperlipidemia and arteriosclerosis, so they avoid it. In fact, fat meat is not only a traditional delicious food, but also a nutrient to promote growth and development, and can also prevent cancer. As long as it is cooked properly, it is beneficial to human health to stew with slow fire and eat some fat meat properly.

Vegetable oil is good. People think that eating animal oil can easily lead to coronary heart disease, obesity and other diseases, so vegetable oil is favored. In fact, this is very one-sided. Because pure vegetable oil can promote the increase of peroxide in the body, affect the absorption of vitamins and increase the incidence of breast cancer and colon cancer; Peroxides formed on blood vessel wall, liver and brain cells can cause arteriosclerosis, liver cirrhosis, cerebral thrombosis and other diseases.

It is correct to eat vegetable oil and animal oil together or alternately, and the ratio is 10:7.

Some parents give their children milk and chocolate at the same time in order to increase their nutrition. In fact, this will be counterproductive. Because milk is rich in protein and calcium, chocolate contains a lot of oxalic acid. Eating together, calcium in milk and oxalic acid in chocolate combine to form calcium oxalate, which is not easy to be absorbed, and can also cause diarrhea and affect development.
