With people’s concern for health, the nutritional level of food has become more and more important, but most people are concerned about what kind of nutrition a single food, such as “bean kidney has a role in kidneyâ€, “more eat bitter gourd can drop Blood glucose, Lu Chunjing, chairman of the Nutrition Society Branch of the Chinese Medical Association, told reporters that from the perspective of modern nutrition science, two or more types of foods, if combined properly, will play a role in complementing each other and complement each other, playing their role in the human body. The greatest effect of health care, however, has long been overlooked by everyone.
Modern Nutrition: Pay attention to the complement of nutrients
“The “tomatoes and scrambled eggs†we often eat is actually one of the most successful examples of food collocation,†Wang Yi, director of dietary nutrition department of Guang’anmen Hospital of China Academy of Traditional Chinese Medicine told reporters. “Because eggs are rich in protein and Vitamins, such as B vitamins, niacin, lecithin, etc., but the only lack of vitamin C, tomato contains a lot of vitamin C, just to make up for its defects, so the two together to eat can play a complementary role in nutrition This is where modern nutrition emphasizes the emphasis on food."
Examples like this can be found everywhere in our lives. Wang Yi said that we advocate that we should eat grains, but also from the perspective of nutritional complementarity, the most typical is the beans. Beans are rich in protein content, but different types of beans have high or low amino acid content, so it's usually best not to eat only one, mixed eating can improve protein absorption and utilization and biological value.
There are also many examples of misconduct due to lack of understanding of the nutritional content of food. Lu Chunjing pointed out that some food combinations are only considered from the perspective of taste and are likely to cause damage to health. For example, people often eat tea eggs: In addition to alkaloids in tea, there are acidic substances, these compounds combined with the iron in eggs, have a stimulating effect on the stomach, is not conducive to digestion and absorption. It is best not to add cucumbers when eating the “big harvest†dish. This is particularly emphasized by Wang Yi because cucumbers contain an enzyme that can damage the body's absorption of vitamin C in other vegetables. "Unfortunately, the 'big harvest' in restaurants is now almost without cucumbers," Wang Yi felt particularly sorry for the nutritional losses caused by improper food collocation.
Traditional Medicine: Collaborate to Strengthen the Therapeutic Effect
The importance of food collocation has been discussed in Chinese medicine more than 2,000 years ago. Zhang Hude, a professor of health at the Beijing University of Traditional Chinese Medicine, told reporters that the main basis is the “gas†and “taste†of food. He said that Chinese medicine believes that food has “four gases†(cold, hot, warm, cool) and “five flavors†(single, sweet, sour, bitter and salty). The principle of food collocation is cold and heat, sympathy and sweetness. balance.
Specifically, Prof. Zhang pointed out that Chinese medicine has four kinds of situations in terms of food mix. The first two can enhance the therapeutic effect: First, the phase must be comparable, that is, the food with the same performance or similar performance in some aspects, can be different degrees. Enhances the original therapeutic effect. Such as "Dangguisheng ginger mutton soup", warm blood blood mutton and blood and pain relief of Angelica and cold and cold in the compatibility of ginger, can enhance the deficiency of cold pain and pain, but also can remove the smell of lamb. The second is to kill each other in a similar way. When two foods are used together, the toxicity or side effects of one food can be reduced or eliminated by another food. Such as garlic can prevent mushrooms, lentil poisoning, olive solution puffer fish, fish, crab caused by mild poisoning.
Professor Zhang said that there are two situations in food collocation that may weaken the effect of therapeutics. Therefore, it is necessary to avoid the following: First, evil, that is, after the two foods are used together, due to mutual restraint, the original function is reduced or even lost. Such as eating lamb, dog meat and the like warm blood food, try not to eat green beans, fresh radish, watermelon, etc., otherwise it will weaken the warming effect of the former. The second is the opposite. When the two foods are used together, they can produce significant side effects such as toxic reactions or diarrhea, such as honey onions, cucumber anti-peanuts, and goose anti-pear.
How to match in life
From the perspective of modern nutrition or traditional Chinese medicine theory, it takes a certain amount of expertise to understand the collocation of food. For the ordinary people, there is no easy way in life to make the food more scientific. What?
According to Li Ruifen, dietitian of the Beijing Military Region General Hospital and renowned nutritionist in China, the purpose of food collocation is to maximize the balance between diet and nutrition. Therefore, it is the basic principle of collocation to eat as much food as possible in life. . For example, nutritionists in China recommend that people eat 30 to 35 kinds of food every day in addition to water. This number seems to be more than it is actually not difficult to achieve, because the food seasonings such as pepper, aniseed, etc. are considered one of them. In addition to "more", we must also pay attention to "far" and "miscellaneous." "Far" means that the farther possible is the kind of food eaten in a day, such as chickens, fish, and pigs are better than chickens, ducks, geese or pigs, cattle, and sheep; "miscellaneous" is vegetables, meat, food, etc. Different types of food should be eaten so that nutrients work together.
In addition, there are several kinds of collocation is also essential, Li Ruifen said, first, we must pay attention to the balance between staple food and non-staple food. Millet, oats, sorghum, corn and other miscellaneous grains rich in nutrients in the minerals, the body can not be synthesized, can only rely on ingestion from the outside world, it can not just eat vegetables, meat, ignore the staple food. The second is the balance between acidic foods and alkaline foods. Acidic foods include foods containing more non-metallic elements such as sulfur, phosphorus, and chlorine, such as meat, eggs, poultry, fish and shrimp, and rice noodles; alkaline foods mainly contain metallic elements such as calcium, potassium, sodium, and magnesium. Food, including vegetables, fruits, beans, milk, tea, fungi, etc. Eating too much acidic food can make people feel tired, memory loss, inability to concentrate, backache, increased risk of illness, and need certain alkaline foods to neutralize. The third is the balance between dry and thin. Eating only dry foods will affect the absorption of the stomach and stomach, and it will easily lead to constipation. However, eating light food can easily lead to vitamin deficiency. Li Ruifen believes that as long as the diet has mastered the major principles of these food combinations, it can basically ensure balanced nutrition.
