There is a fruit that is now in the right time, and it is also the "heart" of many children, that is, "oranges".
The smell of oranges is fragrant, sweet and sour, and rich in juice, which is impossible to refuse for children who love fruit.
Even in textbooks, their traces are indispensable: Bingxin's "Little Orange Lantern", Zhu Ziqing's "Back Shadow"...
Wait a minute! Do you remember whether it was "orange" or "orange"?
"Orange" or "Orange"?
"Orange" and "Tangerine" were originally two different plants. Tangerine, pronounced jú, is the name of the tree, that is, the orange tree, the fruit is reddish yellow, the flesh is juicy, sweet and sour, is a common fruit. Also called its fruit. Tangerine, pronounced jié, is a perennial herb whose roots can be used medicinally. Also known as bellflower. However, many parts of the country now use "orange" as the "common word" for "orange". In this sense, "orange" is also pronounced jú.
In ancient texts, the words "orange" and "orange" "well water does not violate river water", using "clear distinction", never mixed and matched.
According to scholars' research, the entanglement of the words "orange" and "orange" began around the end of the Ming Dynasty and the beginning of the Qing Dynasty. Other scholars say that writing "orange" as "orange" may also be related to folk customs. In modern classical literature, there are also use cases of replacing "orange" with "orange". The most famous example is Bingxin's "Little Orange Lantern", and in modern botany books, examples of "orange" instead of "orange" can also be found. However, in the national standard documents, it is still "orange" that is recognized.
In the historical national standard documents, the status of the word "orange" is "as stable as Mount Tai" and has never wavered. "Tangerine" was neither abolished nor simplified to "orange" as a variant of "orange". (In the Second Chinese Character Simplification Plan (Draft), promulgated in 1977 and abolished in 1986, "orange" was simplified to "orange") Various reference books have also regarded "orange" as the orthographic character and "orange" as its "common character".
Therefore, in official documents such as books, newspapers and periodicals, it is still recommended not to write "orange" as "orange".
Nutrition of oranges
Tangerines have been cultivated on the mainland and India since ancient times, with a history of more than 3,000 years. Its soluble sugars, organic acids, flavonoids and limonins combine to give the orange its unique flavor.
The nutrition of oranges is not bad, although the content of dietary fiber is not very rich, but the content of vitamin C and the mineral potassium is not bad.
The Chinese Food Composition Table lists the nutritional content of many oranges, and although there will be differences between different varieties, they are not very large.
As can be seen from the table, the lowest calorie of common orange varieties is small-leaf orange, the richest dietary fiber is honey orange and kumquat, the higher vitamin C content is orange mandarin and kumquat, and the most potassium supplement is Three Lakes red orange.
In addition, oranges are also rich in carotene and folate, of which the content of folic acid is 52.9 mcg/100 g, which is 8.4 times that of apples.
Eat 1 orange a day
Citrus, as the most common fruit eaten in autumn and winter, if the child eats one a day, what changes will the body have?
Supplement with adequate vitamin C
The vitamin C content of oranges is usually between 20~40mg/100g, basically a medium-sized orange can meet half of the child's daily vitamin C needs.
Adequate intake of vitamin C in the diet not only helps the body maintain normal immune function, but also helps maintain skin elasticity and prevent dry skin.
Protect your eyes
The carotene content in oranges is usually 370~5140 micrograms/100 grams, and in common orange varieties, the higher carotene content is small-leaf orange and early orange, with content of 2460 micrograms/100 grams and 5140 micrograms/100 grams, respectively. Eating more carotene-rich foods in the diet is good for eye health.
Maintain electrolyte balance
The potassium content in oranges is not bad, and the intake of fruits with high potassium content can better maintain electrolyte balance, control blood pressure, diuresis and reduce swelling.
Eliminate fatigue
The content of citric acid in oranges is very high, and citric acid not only has an appetizing effect, but also has the effect of eliminating fatigue.
Oranges are good, but don't be greedy
Although oranges are delicious, you can't let your child eat too much, otherwise it may -
Transform into a "Minion"
Oranges are rich in carotene, if you often eat a lot of oranges, the human body will ingest too much carotene, the human body can not be metabolized, the content in the blood is too high, it will lead to yellowing of the skin, this situation is called "hypercaroteneemia", also called "orange syndrome", the typical manifestation of this symptom is that the palms, soles of the feet are obviously yellow, severe and even the skin of the whole body will turn yellow.
However, it will only affect the appearance for a short time, and will not affect health. As long as you don't eat yellow oranges for a while, you can return to normal in a week or two, and you generally don't need special treatment.
In addition to citrus (oranges), carrots, pumpkins, papayas, mangoes and other fruits and vegetables are also rich in carotene, and if you eat a lot, you will also become a "minion".
"On fire"
In fact, if the physical condition is normal, then eating oranges themselves will not catch fire.
The reason for the symptoms similar to fire is actually because after excessive sugar intake, a mucus reaction occurs in the body, and if there are pathogenic bacteria in the body at this time, it is particularly easy to cause inflammation, but this is not really on fire.
Tangerines also contain acidic components (fruit acids), which are also irritating to the mucous membranes, and eating too much will also produce symptoms similar to fire. Whether it is sugar or fruit acid, once ingested in excess, it will cause inflammation similar to fire, so you must not be gluttonous.
Oranges are all over "treasure"?
Some parents believe that "eating more white bowls in oranges is beneficial", is this really the case?
The white filament on the orange is called orange thread, also known as orange silk and orange tendon. Orange is actually a kind of peel, mainly composed of water and dietary fiber, in addition to some plant polyphenols.
Although it is true that there is some nutrition, considering that the amount of white bowl per orange is too small, if the child does not accept it, there is no need to force the child to eat it in order to pursue nutrition.
If the child doesn't hate it, it's better to eat it with orange pulp.
In addition to orange peels, orange peels are often collected by many people to dry and make "tangerine peels" for soaking in water and drinking.
In fact, there is a misconception here:
More than three years is called tangerine peel, this stage of the skin contains less moisture, sugar and volatile oil, not easy to burn skin, moisture, mildew and moth, darker color, no fresh fruit smell.
No more than three years called citrus peel or fruit peel, orange peel at this stage contains more moisture, sugar and volatile oil, easy to burn skin, moisture, mildew and moth, light color, with fresh fruit smell.
Citrus has an aromatic smell that can be used to a certain extent. In autumn and winter, the indoor air conditioner is turned on, resulting in no air circulation, relatively many germs, if you put an orange in the bedroom, the fresh smell, can stimulate the excitement of the nervous system, make people refreshed, clear the dirty air, relatively beautify the indoor environment.
However, because the peel of orange fruits such as oranges and grapefruit contains aromatic hydrocarbon compounds, the substance has a strong solubility in rubber and can be dissolved instantly.
Therefore, when the child eats citrus fruits such as oranges, oranges, grapefruit, lemons, etc., do not let the child near the balloon. After the child eats the fruit, rinse the peeled hand with clean water and throw the peel into the trash before touching the balloon.
