How many taboos are known about oranges

Oranges are really popular in China, whether it is ugly oranges that are bigger than a fist or sugar oranges that are too small, from the three eastern provinces to The Yunnan Guangmin, there are loyal fans everywhere. However, there are many kinds of "gossip" about oranges.

Oranges are rich in vitamins, good for health to eat more? The content of vitamin C (VC) in citrus fruits is usually 20mg to 30mg/100g, which is much more than apples (1mg~5mg/100g) and pears (4mg~8mg/100g). For example, oranges are well hydrated, soft and tender flesh, sweet and sour, the price is close to the people, in the winter when fresh fruits and vegetables are not so rich, popularity is inevitable, basically a medium-sized orange can meet half of the child's daily vitamin C needs. Moreover, it is also rich in potassium, carotenoids, as well as hesperidin, naringin, etc., which are all health-beneficial ingredients. However, no matter how nutritious food is, there must be a quantity to eat. In the case of oranges, the problem is that there is a little too much sugar. The sugar content in oranges averages 11.9%, and if you encounter a sweeter variety, it will be higher. And oranges because they do not need to wash, peel to eat, soft taste of these reasons, it is easy to "eat more carelessly", these oranges down, energy intake can not be low. China's dietary guidelines recommend that the amount of fruit eaten by ordinary adults every day is about 200g to 350g, which is converted to citrus, which is almost 2 to 3 medium-sized oranges. If you really love to eat, eating one or two more is not a big problem, eat more oranges to eat less other staple foods, and be sure to pay attention to cleaning your teeth.

Eating more oranges will turn into "minions"? In fact, there is nothing to do with dyeing, eating orange skin will turn yellow, because citrus is rich in carotene, if you often eat a lot of oranges, the human body will ingest too much carotene, not metabolized in time, the content in the blood is too high, it will lead to skin yellowing, this situation is called "hypercaroteneemia", also known as "orange syndrome", the typical manifestation of this symptom is that the palms, soles of the feet are obviously yellowed, and the serious 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 temporarily stop eating oranges, your skin color will return to normal in a week or two, and you generally do not need special treatment. Moreover, in addition to citrus, carrots, pumpkins, papayas, mangoes and other fruits and vegetables are also rich in carotene, if you eat a lot, you will also become a "minion". If you find that your face has turned a little yellow recently, think about whether you have recently consumed too much of these fruits and vegetables.

Will oranges catch fire when they eat too much? In fact, for oranges, the "fire" is caused by the high sugar content in oranges. Eating too many oranges means that you will consume a lot of sugar. High sugar can dry and astringent throat; some sensitive people may also feel discomfort in their gums and stomach because of the fruit acid in oranges. If the mouth is not cleaned in time after eating, these food residues and sugars are easy to cause bacteria in the mouth to breed and cause inflammation, which may be manifested as inflammation of the gums in the early stages, and the main features are red and swollen gums, easy to bleed, and swelling and pain. These are not very similar to the fruit after feeling "on fire" performance, the solution is very simple, do not greedy, eat one or two a day can be, and after eating oranges in time with floss to clean the flesh residue between the teeth, and rinse the mouth with water in time, so that there will be no "fire" situation.

Is it beneficial to eat more whites in oranges? The white cotton flocculent and filamentous substance wrapped on the inside of the orange peel and the orange petal is called the orange network, which is actually a kind of peel, and its components are mainly water and dietary fiber, and there are also some plant polyphenols. However, the amount of white rice is too small, and the taste is not very good, after all, most of it is dietary fiber, if you feel that it is a pity to lose it, then eat it. If you really want to supplement dietary fiber, it is better to eat more grains.

Oranges are divided into male and female, and female oranges are sweeter? There is no scientific basis for this claim. The key to the so-called "male-female distinction" in this statement is the "umbilicus" located at the bottom of the fruit (opposite to the stalk), which is actually a scar left on the fruit by the flower organ that has fallen off. These scars are mainly remnants of vascular bundles that transport water and nutrients, and because the underlying peel tissue usually develops more slowly (or even not develop) than the rest of the fruit, forming a slightly sunken "umbilicus". The size of the umbilical cord is continuously distributed among the different fruits, there is no clear boundary to divide the male and female, and there is no evidence that the development of this small piece of the umbilical skin is related to the taste of the fruit. In fact, citrus, orange, orange, grapefruit are all citrus fruits, their taste of acid and sweetness, are directly related to the soil, fertilizer, sunshine, tree age, etc.; the origin, variety, shape of different, the taste of oranges is also different.
