A while ago, on a whim, I bought a box of oranges for my parents online. After they received it, they immediately called me, I thought they would praise me for my filial piety, but who knew that there was a "lesson" on the other end of the phone.
"Xiao Zhang, how can you buy fruit on the Internet?" said Dad, "These oranges are all male, how can you pick them yourself!"
As soon as I heard it, I was happy, "Dad, are oranges still male and female?"
"Of course, the female orange is sweet. These male oranges are afraid that they are sour. Mom said.
I suddenly became curious, "Then how do you tell if the orange is male or female?"
Dad smiled, "Look at the bottom of this orange, there is a small circle, and that is the mother's." Male oranges do not have. ”
After hanging up the phone, I was still confused. Is there really a male and female fruit? Are female oranges really sweeter?
01
It is a popular saying that fruits are believed to be male and female, but in reality, there is no conclusive scientific evidence to support this claim.
Many people may have heard of this statement, just like the experience of the landlord buying oranges online, and the parents' perception of this statement may be derived from the oral tradition of the elders, however, when we dig deeper, we will find that this statement is actually a metaphor for the shape of the fruit.
When it comes to the male and female theory of fruits, one of the most common examples is oranges. When picking oranges, the elders often instruct us to look at the "umbilicus" at the top of the fruit, and distinguish the so-called male and female oranges accordingly.
However, the truth is that this "umbilicus" is actually a scar left by the flower organ that falls off when the fruit bears fruit.
Despite this claim, there is no scientific research to prove that the "male and female" of oranges are directly related to the sweetness or taste of the fruit.
The sweetness of oranges is related to factors such as fruit variety, tree age, and cultivation environment. Therefore, it is often inaccurate to judge the sweetness of a fruit simply by looking at its appearance.
Even for the same variety of oranges, different tree ages and different cultivation environments will affect their sweetness. Therefore, there is a lack of scientific support for the theory of male and female.
A similar statement exists for other fruits, such as apples, pears, etc. Some people think that the bottom of the fruit is depressed is the mother fruit, and the bottom of the fruit is raised.
However, this claim is not scientific and cannot be used as an accurate basis for judging the sweetness or taste of fruits.
02
First of all, it is necessary to choose fruits with a full appearance, bright color and no obvious scars on the surface.
Secondly, pay attention to the aroma of the fruit, fresh fruit usually gives off a strong natural aroma.
Finally, you can gently pinch the fruit with your hands, and if the surface of the fruit is slightly elastic, it means that the fruit is ripe. These methods may be more practical than judging the quality of the fruit based on the male and female opinions.

Oranges are a common fruit that is loved for its rich nutrients such as vitamin C and pectin.
However, some claims about the consumption of oranges have made people wonder, such as the claim that eating too much will cause the skin to turn yellow or cause the body to "catch fire". Let's explore the truth of these claims.
01 Will oranges turn yellow if you eat too much?
Oranges are rich in carotene, and when carotene accumulates in large quantities in the body, it may cause yellow pigmentation on the skin, whites of the eyes, and other parts, which can make people look yellow.
This condition is known as hypercarotenemia, but to cause this phenomenon, a long-term high intake of carotene-containing foods, mostly yellow or orange vegetables and fruits, is required.
In the case of oranges, it is precisely because they are rich in carotene that excessive consumption may lead to hypercarotenemia, but this condition usually does not have a significant effect on physical health, as long as you stop consuming foods containing high amounts of carotene, the yellow pigmentation will disappear naturally.
02 Will eating too many oranges "catch fire"?
The so-called "Shanghuo" is a concept in traditional Chinese medicine theory, which refers to a series of physical discomfort symptoms caused by the imbalance of yin and yang in the body, and the poor flow of qi and blood.
Although oranges are rich in nutrients such as vitamin C, there is no direct evidence that it causes "fire".
However, oranges contain a lot of fructose and glucose, and excessive intake of these simple carbohydrates can lead to an increase in blood sugar levels, which can worsen for people who already have diabetes or have poor blood sugar control.
In addition, for some people, excessive consumption of oranges may cause problems such as mouth sores, swollen and sore gums, but this is not the same as what Chinese medicine calls "getting on fire".
Therefore, in general, the claim that eating too many oranges will cause the skin to turn yellow is true to a certain extent, but it does not have a serious impact on physical health, as long as it is consumed in moderation, the yellow pigmentation will naturally subside.
The claim that oranges can cause the body to "get on fire" is not accurate, and although excessive consumption of oranges may cause some oral health problems, it does not lead to the so-called "fire" phenomenon in traditional Chinese medicine.
