Everyone eats every day, but not everyone will eat scientifically. For this reason, many experts summarize the “gold standard” of healthy eating. People eat when the body is in a relaxed state, it is easy to chest hunching. Do not know, this will make the esophagus and stomach pressure, affecting digestion. In addition, eating in front of a short table, sitting on the sofa and squatting to eat, will cause abdominal pressure, affecting the blood circulation of the digestive tract, which over time can lead to gastric problems, affecting cardiopulmonary function. The correct eating posture is to straighten the back, so that the stomach is not subject to any pressure. People in extreme hunger when the appetite is particularly strong, see what all want to eat. In fact, at this moment the gastrointestinal digestive function has been impaired, if you eat and drink is easy to cause food stagnation. Particularly hungry, should be a small amount into some semi-fluid food, and then slowly return to normal diet. Especially note, especially hungry do not eat milk, soy milk, yogurt and white potatoes, may cause digestive problems. Too long or too short an interval between meals will have an impact on the human body, too long will cause a high degree of hunger, affecting labor and work efficiency; too short an interval, the digestive organs do not get proper rest, will affect appetite and digestion. General mixed food in the stomach stays about 4 to 5 hours, therefore, two meals between 4 to 6 hours is more appropriate. After meals, the body’s blood will be concentrated flow to the digestive organs, the brain is relatively ischemic. Using the brain at this time will cause mental tension, memory loss and other problems, and may also increase the incidence of cardiovascular and cerebrovascular diseases. Therefore, it is necessary to rest for more than half an hour after meals before starting work. Listening to music and taking a walk after meals are good choices. Early in the morning, the nerves and blood vessels in the body are still in a state of contraction, at this time if you eat cold food, may make the digestive system spasm. Chinese medicine believes that breakfast should eat hot food, to protect the stomach qi. It is recommended to choose hot porridge, hot cereal, hot soybean milk, etc. for breakfast, together with buns, bread and other staple foods. Tea should not be consumed immediately after meals, otherwise it will dilute gastric juices and affect food digestion. At the same time, the tannins in the tea and the protein in the food will be mixed to produce indigestible solidified substances, to the stomach to increase the burden. Half an hour after the meal and then drink tea, can promote digestion and absorption, play the role of sterilization and dental care. After 7:00 p.m., the human body fluid metabolism decline, this time to eat cold food, especially cold drinks, not easy to eliminate fatigue will also affect sleep. Dark-colored vegetables are dark green, red, purple-red vegetables. The Chinese Nutrition Society recommends that you should eat a pound of vegetables every day, of which dark-colored vegetables should account for more than half, and its vitamin C content is twice as high as that of light-colored ones. For example, dark purple eggplants versus light green eggplants, purple onions versus white onions, purple kale versus cabbage, purple potatoes versus sweet potatoes and white potatoes, the former are significantly more nutritious than the latter. Eat vegetable oil will promote the increase of peroxide in the body, accelerate the aging of people, but also affect the body’s absorption of vitamins, increase the incidence of breast cancer, colon cancer. Animal oil contains beneficial cardiovascular polyenoic acid, lipoproteins and so on. Experts remind, with 1 part of animal oil, 2 parts of vegetable oil made of mixed oil, you can take the long and make up for the shortcomings. The absorption and utilization of calcium in the human body is restricted by many factors. Calcium-rich foods include milk, eggs, bone broth, fish, shrimp and soybeans. Insufficient acidity in the gastrointestinal tract will affect the absorption of calcium. Therefore, cooking food with some vinegar can convert calcium in food into easily absorbed calcium acetate. The body ingests excess fat and protein, and the role of E. coli bacteria, will become harmful spoilage. Fiber can surround them and excrete them. Therefore, it is best to eat a little bit of crude fiber food every day, such as oats, brown rice, barley, sweet potatoes and corn. Depending on your age, supplement with hard foods such as fruits, sugar cane, and raw cucumbers. This is because harder foods to chew hard, when chewing more often or faster, the brain’s blood flow increased significantly, activating the cerebral cortex, can play a role in preventing brain aging and preventing Alzheimer’s disease. Chewing slowly helps digestion, experts suggest that every bite of rice put down the chopsticks, focus on chewing in the mouth, each bite should be chewed carefully more than 30 times. The new U.S. Dietary Guidelines recommend that the amount of salt consumed per person per day should be reduced to less than 2,300 milligrams (about one teaspoon). Those over the age of 51 and those with chronic diseases such as high blood pressure and diabetes should reduce their daily salt intake to less than 1,500 milligrams.
