As the saying goes: "fruit is gold in the morning, silver in the noon and iron in the evening. Nutritionists point out that when you get up in the morning, the liver sugar stored in the day is exhausted. Especially during sleep, the brain will continue to consume sugar. At this time, the sugar in the fruit can be quickly converted into glucose, which is conducive to the formation of liver sugar.
Compared with meat, poultry, fish, eggs and grains, fruits and vegetables have their own characteristics in nutrition, which are rich in vitamins and dietary fiber. Vitamin is a kind of organic matter with small molecule. Although the human body needs less, it has many important physiological functions. The problem is that as an organic substance, its nature is not stable, and it is easy to denaturate and destroy in the process of processing and cooking. In particular, vitamin C is particularly sensitive to temperature and has a great loss when heated and boiled. The third national nutrition survey showed that the amount of vitamin C consumed per capita in China reached 180% of the recommended requirement. However, mild vitamin C deficiency is common in the population. The reason is that a large amount of vitamin C is lost when vegetables are cooked into dishes, and the actual intake of vitamin C is greatly reduced.
Raw fruit is not processed, and vitamin is rarely lost, which makes up for the shortage of vegetables. Therefore, it is better to take fruit as part of the dietary structure, and arrange a fruit for each meal to supplement vitamins, especially vitamin C, which is beneficial to improving the overall nutritional quality of each meal.
Many families are accustomed to eating fruit once a day, which is obviously better at breakfast, because breakfast is relatively simple, there are few dishes to accompany, and more need fruit to provide vitamins. In addition, after a night's sleep, the gastrointestinal tract has been emptied, and the dietary fiber in fruits can play a more "scavenger" role, removing harmful substances on the intestinal wall and eliminating the risk of intestinal cancer. Dietary fiber also has the function of regulating and improving blood glucose and blood lipid, and improving human immunity. Keep healthy, start in the morning.
Health and balanced diet experts suggest that you should eat two servings of fruit a day, so you can divide it into breakfast and lunch. According to the theory of traditional Chinese medicine, eating something cold at night will make the body temperature drop, and those with spleen and stomach deficiency are prone to flatulence. As for many people like to eat fruit after a meal, in fact, it is better to eat it on an empty stomach than after a meal. It is easy to have high blood sugar after eating after meals, and it is also easy to produce bloating after fruit fermentation.
