After the Han Dynasty, two meals a day gradually became three or four meals. Moreover, the three meals began to be divided into breakfast, lunch and dinner. Breakfast, called cold utensils in the Han Dynasty, refers to the snacks used after getting up in the morning and washing. To the Tang dynasty, cold tools began to have the name of heart. "A Random Record of NengGai Zhai" says: "The secular case takes morning snacks as snacks, which has been said since the Tang Dynasty." Up to now, breakfast is still called breakfast in many areas of our country. Lunch was once called "lunch" or "lunch" by the ancients.
When you have two meals a day, people think that "the sage and the people plow and eat, and they start with food" (Mencius Teng Wengong). If you eat food, it means the passage of a day. Today, people often use the term "three meals a day" to express different feelings about time, including those who cherish time.
Three meals a day is something we are used to, but why three meals instead of two or five? This also starts from an old legend.
100 years ago, men had a hard life and never got enough food. Sometimes, he eats every third day, and sometimes only every fifth or sixth day, so he is always hungry, even though he works all day and one night. He really wants pity.
The emperor's paradise, poor human beings, because they keep working hard and don't get enough food. He ordered his theme, Baolu, that is, Baolu star in the sky, went to the earth and said, "If you are a man full of energy, you can have a meal every three days".
The treasure road, however, misunderstood his orders. He quickly descended to the earth and announced to the people: "The emperor's paradise says you should eat three meals a day, not starve to death any more." When he returned to heaven and presented his report, he was punished for his mistake. He was sent down to the earth to help the officers and men in the plow. "I told you to tell them, saying," Emperor, "they should have a meal every three days, but now you give them three meals a day. Think about it; Officers and soldiers only have two hands and two feet-how can they prepare three meals a day? This is all your fault, you must answer, because you have to descend to the earth and help men plow so that they can get three meals a day.
Therefore, Baolu fell to the earth and helped the officers and men farm. These animals are now on the earth originally from heaven.
People have the most energy, the best memory and the most active digestive enzymes in the morning and evening. So breakfast is best arranged around seven o'clock in the morning. Dinner is best arranged around 5: 30 in the evening, when the digestibility is the highest. However, the residence time of food in the stomach is about five-quarters of an hour, and the transformation ability of the liver is limited. Therefore, you must have a meal at noon, and the time is best arranged at around twelve o'clock. At this time, it is also the stage with the strongest appetite. There is no need to add meals at other times.
In addition, there is a specific time for incidental+meals:
Experts say that three meals a day is unscientific and should be eaten every three hours.
"The most fashionable healthy eating habit is to care about the time of each meal, not just what food is on your plate as before." This was announced by a nutrition expert from Cambridge University in England.
Before, some nutrition experts thought that before 16 o'clock to 19 o'clock is the best time for us to eat main foods every day. However, through research, Philip, an expert from the British Dietetic Association, proved that this view is not correct, because the period before 16 is too long, which is not conducive to human health.
In life, we eat three meals a day, but this lifestyle is unscientific. Others said that it is also wrong to have a dinner every three hours every day. So what kind of eating time is scientific? Nutritionists at Cambridge University in England have worked out a scientific meal time according to the law of human metabolism.
Breakfast: 7: 00 to 8: 00
Nutrition expert: After proper morning exercise (such as running or yoga), 7 am to 8 am is the best time to have breakfast.
Extra meal: 10 o'clock
By this time, brain work has consumed 20% of the energy provided by the food you eat for breakfast, so you need to supplement some low-fat carbohydrates, such as bananas.
Lunch: 13 o'clock
This time is the lowest point of energy left in the human body, so you must eat in time and choose high-calorie foods.
Extra meals: 14 o'clock to 15 o'clock.
At this time, the amount of glucose in the human body dropped to the lowest point after lunch. So you can eat some nuts, popcorn, fresh and dried fruits and so on.
Dinner: 17 to 19.
At this time, you should have a formal dinner, so that your body can get enough energy during the next few hours of sleep. In addition, eating at this time can also make food fully digested before going to bed.
Extra meals: 19 to 2 1 point
Choose a small piece of cheese and banana, because they can help you improve the quality of sleep.
Eat well in the morning, eat less in the afternoon if you are full at noon, and then you'd better not eat at night. Dinner is generally not suitable after 8-9 o'clock. Eating during that time is equivalent to eating three meals during the day.
