A. Peel, or peel it off
I don’t know when “eating with skin is nutritious enough” has become a guiding principle for eating fruits. Every time under the wife’s coercion, chewing apples mixed with green peel, so that the taste buds suffer from torture. At the same time, the family’s fruit knives and peelers are in danger of being laid off. Whenever this happens, I can’t help but wonder if the sacrificed taste can be replaced by adequate nutrition.
Except for fruits like kumquats, whose skin is the selling point, I am afraid that most of the peels will not be comfortable for our tongues. For the fruit, this layer of cells to prevent water loss, the second to defend against animal and microbial attack. Therefore, the cells here have to be close together, but also in the external “wax” to delay the loss of water – “taste like chewing wax” feeling naturally is not good to go. Not only that, as a defense system, it is necessary to stockpile some chemical weapons to fight those animals that steal mouth at the wrong time. Although these sour chemical weapons are removed in large quantities when the fruit is ripe, their content is still more or less higher than the inner flesh.
After checking many documents, there is no way to know where the reference to eating the skin of the fruit comes from. In fact, like apples, pears, such as the fruit on the “peel” and “pulp”, in plant anatomy, belong to the same peel structure. More interestingly, such as oranges are discarded peel, from the structure, equivalent to the apple “peel” plus “pulp”. The so-called peel is nutritious, more like a fortune teller out of the mouth of the smooth truth.
Of course, it would not be too much to say that the nutritional content of the peel is high, after all, this part of the cells are more closely arranged and less water. But don’t forget that even if the “content” is several times higher than the flesh, the contribution of the peel to the total amount of nutrients is minimal, considering the weight ratio between the two.
The only thing that the peels have to show for themselves is that they contain pigments such as anthocyanins, which are usually lacking in the flesh. However, these pigments are mostly useful for attracting animals to feed on them. As for the emerging health benefits, I’m afraid you’ll have to take a big bite out of the peeled fruit.
One thing to keep in mind is that even with normal pesticide use, the pesticide residues on the skin of apples are 20% higher than in the flesh. Although these residues, which carry normal residues, do not cause toxic reactions, who can guarantee that some farmers who are forced to produce big beautiful apples will not greet them with more pesticides of pesticides? Those organically grown apples can be chewed with confidence (provided they are really organically grown), but even if they are organically grown, the nutrition in the peel will not increase, and it is not a smart choice to use a lot of money for the legendary nutrition and poor taste.
Of course, the peel is not useless, and the pigments in it can indeed decorate our tables. Dry red wine owes its sizzling color to the pigments in the skins. Researchers are trying to extract natural pigments from different fruit skins (orange from apricot skins, purple from mangosteen, etc.) to add colorful and healthy pigments to our tables.
Second, sucking venom to save lives, is it really feasible?
Q: It’s a common story: someone is poisoned and a friend sucks out the venom for him. In this way, can the poisoned person get out of danger? Is there any danger to the person who sucks out the venom?
A: The first question: No way. Second question: There is danger.
In 2002, Professor Barry S. Gold of Johns Hopkins University and Professor Robert A. Barish of the University of Maryland wrote an article in the New England Journal of Medicine criticizing some of the traditionally wrong first aid measures for snake bites, including sucking out the venom.
For the poisoned person, first of all, the venom enters the body within a short time after the bite, so all efforts to suck out the venom will be largely futile. If the wound is cut large in order to suck out the venom, it will often cause unnecessary damage to the adjacent blood vessels and nerves, ultimately doing more harm than good.
In addition, the act of drug use can also contaminate the wound: we all have a large number of microorganisms growing in our mouths, and when we suck out the venom with our mouths, these microorganisms can also be transferred from the mouth to the wound, which may cause more complicated infections in the future.
Professor Gold advises that the best way to prevent the rapid spread of snake venom in the circulatory system for a poisoned person is to remain calm and keep the snake bite wound positioned at a level below the heart, while strictly avoiding running or any activity that will speed up the heart rate.
Then we look at the addict. Although snake venom has the word “poison” in it, it should not be confused with the effects of ordinary poisons. Unlike ordinary poisons, snake venom does not poison you. It only threatens you when it is injected into your soft tissues or bloodstream. But once there are open wounds in your mouth and digestive tract, the consequences of taking snake venom are not substantially different from if you were bitten by a snake.
Although the vast majority of people attacked by snakes end up safe, there are still a very few fatal cases. The question of how long after a snake bite is fatal involves many complex factors: the type of venom, the amount of toxin injected into your body, how the injured person’s immune system reacts to the venom, and how well the injured person responds to treatment. But one thing is certain: the faster you seek medical assistance, the better.
So the next time your partner is bitten by a snake, the best thing you can do for him is to pick up your cell phone and quickly call for help: “Please send an ambulance as soon as possible, or better yet, an ambulance helicopter!” Of course, if you have subdued the snake, then bring the snake to the hospital will also help the doctor’s treatment.
Third, can a kernel of corn be planted into a corn field?
Q: In the Korean movie “Kim’s Drift”, Kim drifts to an island and accidentally finds a grain of corn, which is later planted to produce a batch of corn – first, is it possible to produce many “offspring” from just one grain of corn? Secondly, even if it were possible, how long would it take to grow a crop in the climate and geography of Korea?
A: I have to say that Kim was lucky to harvest a batch of corn from one kernel.
A kernel of corn is a seed, and if it is a seed, it can germinate, it can draw ears, and it can bear seeds. However, people who can’t raise green plants or even cacti know that it’s not easy to grow a live plant, it may not germinate, germinate may grow insects, not grow insects may also be sick, may die of drought or flooding, may lack fertilizer, may be fertilizer “burned” to death, different periods of time to chase different fertilizers ……
Even if it is a variety that has been domesticated by humans and is not too picky about water and fertilizer, it is not an easy task to grow well, because the closer the variety is to humans, the weaker the resistance to natural disasters and diseases, the more dependent on pesticides and field management. In short, Kim can be a farmer when she takes off her suit, she must be talented. This is as likely to happen as getting a diploma from “Western Pacific University” and becoming the president of a Fortune 500 company in China.
In addition, the length of time between sowing and harvesting depends on many factors, climate and geography being only one factor, but more importantly, the variety of corn, which in theory can take anywhere from 2 months to 4 months. However, not as why, generally in the movie plot, you can only get about one season of corn a year.
