Regarding the number of meals per day, there are different customs among different peoples, cultures and geographical conditions. In Islam, there is the month of Ramadan, during which you cannot eat when the sun comes out, and you can eat only at night. In Russia, there is a saying that “the third meal is for the enemy” and people eat only two meals a day when winter comes. At present, it is also popular to eat less and more meals, advocating eating a very small amount of each meal, five or six meals a day. So exactly how many meals per day is reasonable and healthy? Three meals a day is the most scientific. The human digestive tract is designed for three meals a day. During the long evolutionary process, the various organs in our digestive system have been working together and cooperating with each other to complete the task of digesting three meals a day in an efficient and high-quality manner. The digestive tract has been well prepared before meals; once a meal begins, a series of cascade reactions such as secretion and peristalsis of the stomach, secretion of the pancreas, release of bile, and secretion of intestinal fluid begin in an orderly manner, and digestion, absorption, and excretion of food begin. This series of processes takes varying amounts of time, some lasting until several hours after eating. Three meals a day is a balance between providing us with enough energy and providing enough rest time for each organ. Meals too many times, digestive organs and some endocrine organs do not get enough time to rest, long-term, inevitably “overworked wear and tear” or early “aging retirement”. Is not the number of meals the less the better? Many people have the habit of not eating breakfast, this phenomenon is particularly common in college students and white-collar workers, lazy life or the accelerated pace of life and the increase in life pressure is the cause of this phenomenon. Such a lifestyle is extremely unhealthy. There are about 18 hours between dinner and lunch the next day, during which no meal is eaten, bile is stored in the gallbladder and there is no opportunity to excrete it. The gallbladder wall continuously absorbs water from bile and bile is continuously concentrated and crystals are formed, resulting in a high incidence of bile stones in this group of people. In addition, Japanese scholars have done such an experiment, the same high-calorie diet randomly divided into two different groups of normal weight people, one group of two meals to give, the other group of three meals to give, after a period of time, divided into two meals to give people more likely to suffer from obesity. It can be seen that three meals a day can also prevent obesity to some extent. Understand the three meals a day is scientific, so how should we eat each meal to make us energetic every day? There is a common saying: eat a good breakfast, eat a full lunch, eat less dinner. This statement is very scientific. Breakfast most of us have to go to work at eight in the morning, most of the important work to be dealt with in the morning, whether it is mental or physical labor to consume a lot of energy, so breakfast should be eaten well. What should we eat for breakfast? The brain consumes glucose, wheat, cereals and other carbohydrate-based foods are broken down into glucose, which is absorbed and used by the body, so 60%-70% of breakfast should be carbohydrates. Carbohydrates are easier to digest and absorb, and can directly provide energy for the human brain. In addition to carbohydrates, but also with a small amount of protein-based foods and fruits, Westerners are mostly this kind of food with breakfast, practice has proved to be more scientific. Breakfast is mainly bread, with fried eggs or a small glass of milk. Such a breakfast best meets the physiological needs of the human body. Let’s take a look at our traditional breakfast. Old Beijing loves soy milk, doughnuts, coke rings, soy juice, bean curd brains and fried liver, which is very unhealthy. Doughnuts are a typical “junk food”, high temperature cooking and repeated use of oil will produce many carcinogenic substances; high fat content after frying, high calorie food, often eaten easily cause obesity; doughnuts in the production process will add alum, alum contains aluminum, excessive consumption of aluminum on the brain, kidney have chronic toxicity, it is recommended that We try to eat less of this type of food, can occasionally relieve cravings. Some people breakfast is one or two eggs and milk, such breakfast is almost no carbohydrate food, are protein, fat, protein and fat into the body needs to be converted into sugar for the body to use, increase the burden on the body after breakfast, a large amount of blood supply digestive system, supply other parts of the body blood relatively reduced, the brain and other parts of the body energy supply is insufficient, will inevitably lead to work efficiency decreases. So it is recommended that we eat a breakfast based on carbohydrates, eat some bread or rolls, add an egg or half a pound of milk, and after the meal you can eat half an apple or other fruit to supplement vitamins. There is nothing special about lunch, eat enough, master the principle of light-based, coarse and fine collocation. Dinner many people get up too late breakfast rush, from home to bring some lunch to make up and, dinner time is relatively abundant, back home to do more fancy or get together with friends, dinner is very hearty. It is this sumptuous dinner, but there are a large number of health risks. Should eat less in the evening, after dinner activity is very little, sleep state consumption of energy is only 1/2 of the day, and the amount of food eaten at dinner once more than the amount consumed, will all become fat storage. If the fat content of dinner is very high, blood lipids will rise significantly in a short period of time, blood discharge from the heart decreases during sleep, blood flow slows down, blood viscosity increases, and cardiovascular events (stroke, myocardial infarction, etc.) are particularly likely to occur under such circumstances. There are many facts as lessons here, many patients who were fine before going to bed, found in the morning that their mouths were crooked, their faces were paralyzed, they were hemiplegic, and some had even stopped breathing. Therefore, middle-aged and elderly friends, especially those with high blood pressure, hypertension, coronary heart disease and atherosclerosis must eat less and lighter dinners. There are also some friends, after dinner to watch TV pastime eat peanuts, melon seeds and other snacks, in fact, the calorie content of such food is very high, 18 sunflower seeds calories equivalent to a 500 grams of cabbage calories, such snacks are very easy to cause obesity. If you want to eat snacks, it is recommended that you snack on fruits and vegetables, which contain very low calories, not only to meet the desire to eat snacks without gaining weight, but also to supplement the body’s essential vitamins and trace elements, which is very beneficial to health. Science three meals, vitality multiplied. Diet is the cornerstone of health, a healthy diet, is the guarantee of daily energy, physical well-being.
