It is not advisable to work immediately after a meal It is not advisable to work immediately after a meal without resting, as this will affect your health. Because after a meal, the blood vessels of the gastrointestinal tract expand, the blood flow to the gastrointestinal organs increases, which is conducive to the digestion and absorption of food. If you work immediately after the meal, it will force the blood to meet the needs of the moving organs, resulting in insufficient blood supply to the gastrointestinal tract and reduced secretion of digestive juices. In the long run, it will also cause indigestion and chronic gastroenteritis and other diseases. Moreover, after the meal, the stomach is full of food, work is easy to vibration, pulling the mesentery, can cause abdominal discomfort, abdominal pain, gastroptosis. Therefore, it is not appropriate to work immediately after a meal, it is best to rest for an hour and then dry. Not a cup of tea after a meal Many people have set aside the rice bowl to drink tea habit, in fact, this is not desirable. Because just eaten a meal, the stomach full of food, gastric juice is secreting, a lot of tea into the stomach, will dilute gastric juice, affecting digestion. At the same time, but also increased the burden on the stomach, so that the abdominal pressure increases, the heart is also unfavorable. The United States Medical College of Georgia experts pointed out that drinking strong tea after meals is more unfavorable. Tea contains caffeine and tannin, the former will excite the nerves, can cause insomnia; the latter and the combination of protein in the food in the stomach, the formation of indigestible solidified material, affecting the digestion and absorption of protein. After meals should not relax pants belt After meals, such as pants belt loosening, will make the postprandial intra-abdominal pressure drop, the activity of the digestive organs and ligaments of the load increased, this time easy to intestinal torsion, causing intestinal obstruction, but also easy to cause gastric ptosis, epigastric discomfort and other digestive system diseases. Therefore, it is not appropriate to loosen the belt after meals. Do not eat training children A lot of parents, in the learning of children learning or fighting outside trouble, often in the meal reprimanded or scolded the child, this is harmful to the child. First of all, the child cries while eating, rice particles, crumbs and water can easily run into the windpipe when sobbing, causing undue pain to the child. Secondly, before the child is reprimanded, he or she has a strong appetite, but when he or she is suddenly reprimanded by an adult, due to the strong external stimulus, the appetite may disappear, and the secretion of saliva decreases abruptly or even stops. At this time, the child to eat the rice can not be fully mixed with saliva, the food mass is not lubricated, especially when eating hard and rough food, it is easy to cut the esophagus, destroy the mucous layer of the gastrointestinal wall, causing serious inflammation. In addition, food into the stomach, the digestive juices need to be broken down into very fine "particles" to be absorbed by the intestinal wall. Due to the brain's command, the digestive system starts to secrete digestive juices every time before a meal. If a child is reprimanded or scolded by an adult, the food that goes into the stomach will not be fully digested. This not only reduces its absorption rate, but also undigested food, but also increase the corruption of intestinal food, produce toxic substances, light cause loss of appetite, heavy can lead to disease. Therefore, do not scold and reprimand the child at mealtime.

Scientists have found that due to the long-term requirements of their own less food or even do not eat meat, many people have unconsciously become vegetarians. However, long-term non-meat will make the human body needs some nutrients can not be timely replenishment, so that some parts of the human body is damaged. Recently, American scientists have put forward some suggestions for vegetarians to enhance the nutritional structure of their diets. With the strengthening of people's health consciousness and changes in aesthetic concepts, eating more vegetables and fruits has become a very important element in today's disease prevention and health. These gradual vegetarians, together with those who have never touched meat and vegetables for various reasons, constitute a not inconsiderable group. Years of scientific research has shown that although the vegetarian habit for the fight against cardiovascular disease and prevent obesity and other diseases have irrefutable benefits, but because people are currently living in a high-speed modern social environment, so vegetarians in those who need to consume a lot of physical energy in the face of the work is often "sweat". Therefore, vegetarians need to pay more attention to nutrition. Although these foods are more varied, they can be consumed with discretion and in combination. ■ Don't forget calcium supplements Calcium is a key element needed to keep the body working properly. Not only are vegetarians unable to get calcium supplements from meat, they are also unable to get the necessary calcium supplements from it since they basically do not consume dairy products. That's why scientists recommend that, when possible, vegetarians should not exclude dairy products like milk and should consume them in moderation. In addition, regular consumption of soymilk, soybeans, cauliflower, calcium-fortified juices and cereals can play an important role in calcium supplementation. Vegetarians should note that while greens like kale and mustard greens are considered to be high in calcium, not all calcium within dark green vegetables is absorbed by the body. Spinach and beets, for example, are high in oxalates, which can prevent the body from absorbing calcium. Scientists also pointed out that although vegetables can also be a source of calcium, but its effect is far less than dairy products. Vegetarians who do not consume dairy products, eggs, fortified soymilk, etc., should take vitamin B12 every day, and should also take vitamin D to enhance the absorption of calcium. Vegetarians still need fat Scientists have pointed out that vegetarians are more tired of greasy food, but nevertheless, a moderate intake of beneficial fats is not only good for health, but also can play a role in preventing cancer. However, vegetarians are often unable to obtain these fats because they do not eat fish, eggs or seafood. As an alternative, vegetarians can consume foods like flaxseed oil, soybean oil and pecans. Scientists also point out that, in general, a healthy diet should include all the elements and nutrients that the body needs, so when the emphasis is on eating more vegetables and fruits, it should not exclude non-vegetable and fruit foods that provide other important nutrients that the body needs. For those vegetarians who have reached the point where it is difficult to accept meat and fish foods, they need to carefully analyze their current dietary structure, or at least make up for certain nutrient gaps by adopting alternative foods or adding vitamins, so that they can maintain the dietary structure to which they have already become accustomed without affecting the normal functioning of the various parts of the body. For example, take a packet of Bolero Nutritional Punch every day, as Bolero contains biologically active omega3 polyunsaturated fatty acids and egg yolk lecithin, as well as biologically active trivalent chromium, which is one of the most potent insulin enhancers, and vitamin E, which are essential nutrients for the human body. This prevents nutrient imbalances in vegetarians and ensures good health.

How to be considered the most healthy diet with it? Today, we will summarize some more of the most classic combinations of healthy and nourishing diets for you! The common diet of nutritional matching Balanced diet is a day's diet in the appropriate equivalent of grain and cereals, beans, meat, eggs and dairy, vegetables and fruits and fats, and several categories of food to match the right kind of diet. Summarized, the following 10 kinds of matching should be done. 1.

Matching staple food and side dishes: daily diet should be unified with the staple food and side dishes. 3. dry and sparse matching: winter tonic ideal food: angelica ginger mutton soup; water seepage and dampness good: red beans stewed carp soup; lactation good: wild rice loach tofu soup; puzzle good: black sesame paste and the Dream of the Red Chamber of the record of the six kinds of congee (red rice congee, Bie terrier congee, congee, jujube congee, duck congee, congee and bird's nest congee), and also Dunhuang art treasury found in the "Immortal Congee" (made of Gorgonzola berries). "(composed of Gorgon fruit, yam and rice) are typical representatives of dry and thin. 4. Color matching: food is generally divided into 5 colors: white, red, green, black and yellow. A day's diet should take into account the above five colors of food. 5. Nutrient matching: easy to excess fat, carbohydrates and sodium; easy to lack of protein, vitamins, some inorganic salts, water and dietary fiber; high protein and low-fat foods such as fish and shrimp, rabbit, silkworm chrysalis, lotus seeds, etc.; rich in vitamins, inorganic salts, dietary fiber foods such as vegetables and fruits, and roughage, etc.; water is an important nutrient, you should drink more than 4 cups of water a day. 6. Acid-base matching: food is divided into acidic and alkaline food. It is mainly based on whether the food is acidic or alkaline after being ingested by the human body, which ultimately makes the human body's blood acidic or alkaline. In recent years, due to excessive intake of meat food, resulting in blood acidification, triggering rich people's disease, should be taken seriously. 7. Raw heat matching: eat raw eat live has now become a fashion. Eat raw vegetables and fruits, fresh shrimp, silverfish, etc. can intake of more nutrients. Eat raw food live must pay attention to food hygiene. 8. Matching skin and meat: even with the skin and meat to eat together has become fashionable.

According to the principle of "according to the time", different seasons should be used in different food flavors, such as winter should be used in warm food: mutton, venison, cattle prod, ginger, etc., as little as possible to eat cold food. The five flavors should also be matched up, not just eat sweet and not bitter.
