Last year, colleagues received a couple who had been diagnosed with liver cancer. Before the diagnosis, the couple first felt tired and weak for no reason, and then they had chest tightness cough and moderate and low-grade fever.
Even at this time, the husband and wife still did not pay enough attention, and even once thought that it was caused by the recent work being too tired to rest well. It wasn't until the two of them were visibly emaciated at the same time and there was pain in the liver area that they remembered to go to the hospital for examination.
In the hospital, the husband and wife were both diagnosed with liver cancer. Surprisingly, the trigger may be related to fruit.
Couples usually like to eat fruit, always buy a lot at once, and even deliberately buy those rotten fruits in order to be greedy. When I got home, I cut the rotten part and ate the rest.
As everyone knows, a seemingly frugal habit actually harms itself.
Some people may want to ask, is it really so serious to eat a moldy fruit?
Seriously, of course! If you don't believe me, read on!
The toxins in moldy fruits are more than you think!
The reason why fruits are easy to rot is because most fruits are juicy and multi-saccharide and nutritious, and this environment is very suitable for mold reproduction.
The most common toxins in fruits that require attention are:
Penicillin(PAT) ochratoxin A (Ochratoxin A, OTA) produced by Penicillium exhibition
Among them, PAT belongs to class 3 carcinogens and OTAs belong to class 2B carcinogens. Although not as highly carcinogenic as Class 1 carcinogens, the available evidence suggests that PAT can damage the gut, impair kidney function, and contaminate fresh fruits and juices.
OTA is also not a good stubble, not only nephrotoxic, but also liver toxicity.
If you have a fluke mentality and think that not all rotten fruits have these two toxins, then I advise you to dispel this idea.
Because, the vast majority of rotten fruits have penicillin and ochratoxin A!
Of course, the "power" of these two toxins is already very small, and the real "powerful" is in the back. For example, the toxin of Rhodobacterium nodosporum, which is often found in putrid sugarcane, is a strong carcinogen that has been identified.
There is also aflatoxin present in the dried fruit, which is not only a class 1 strong carcinogen, but also 68 times more toxic than arsenic!
Rotten fruit, cut off the broken part can eat the rest?
Not recommended! Why?
Because this is an extremely demanding technical task, no one can guarantee whether the toxin has spread, and even if it does not spread, it cannot guarantee that the toxin will be completely removed.
What's more, most of the decay occurs inside the fruit and is not visible to the naked eye. Moreover, the juice inside the fruit is often circulating, and the toxin may have spread along the juice.
For example, in the following peach, the number of fungi that have rotted parts is 82,500:
The number of fungi that appear to be intact on the surface without any decay is actually as high as 53,100:
Therefore, as long as the fruit has rotten places, it must be thrown away, don't gamble with your own health, no one can afford to gamble!
These two rotten fruits can be eaten!
Not all rotten fruits cannot be eaten, we still have to see what causes it. For example, the following two fruits, even if rotten, can be eaten.
Mechanical injuries (bruises)
Fruit is inevitably squeezed and bumped during picking, transporting and selling, which can lead to damage to the skin of the fruit.
This kind of fruit that is damaged due to external forces can be eaten with confidence, because this only affects the beauty of the fruit and does not produce microorganisms or toxins.
Many people are curious, can you still eat it after the damage has changed color?
It is also edible, in fact, this is the dissolution of the cytoplasm of the fruit, and the colorless phenolic substances become colored quinones in this process.
Low temperature injury (frostbite)
When the temperature is relatively low, the superoxide dismutase activity in the fruit will become low, and then the free radicals in the cells cannot be removed in time. When it accumulates to a certain extent, the permeability of the fruit cell membrane changes.
In addition, the lower temperature environment will also improve the pectin esterase activity in the fruit, pectin esterase will break down the insoluble pectin substances in the fruit, at this time the fruit will also appear soft or rotten and other symptoms.
To sum up, the frostbitten fruit has no microorganisms to multiply, but the cells are damaged and can be eaten, but it must be eaten as soon as possible.
But it must be reminded that everyone must distinguish clearly which fruits are due to external damage or frostbite, and which are spoiled and rotten fruits. Nowadays, many fruit shops will sell moldy fruits at low prices, deliberately concealing moldy decay. There are even some milk tea shops that also use rotten fruits to make fruit tea, and in August last year, the media exposed the news of the use of rotten fruits in "Nai Xue's tea", everyone must pay attention!
These moldy foods that are easy to cause poisoning should also be vigilant!
Moldy sugarcane
Moldy sugar cane produces neurotoxins and damages the central nervous system and digestive system. Within 2-8 hours of consumption, people will develop symptoms of poisoning.
When symptoms are severe, symptoms of nervous system toxicity occur, such as urinary and urinary incontinence, convulsions, etc. If it is not treated in time, it will develop into a vegetative person or even die.
Therefore, when you see that the skin is not shiny, the texture is relatively soft, the color of the part is darker, there are dark gray spots, or the sugarcane that smells of "lees" smells, you must not buy it or eat it!
Moldy eggs
The surface of the eggshell itself has a protective film, which is washed off if the egg gets wet or gets wet. At this point, bacteria can enter the egg and cause the egg to deteriorate.
Therefore, if black spots appear on the surface of the eggshell, you must not eat it.
Moldy peanuts and melon seeds
When we usually eat nuts such as peanuts and melon seeds, we suddenly eat a very bitter one, in fact, it is already moldy. And this bitter taste comes from the infamous aflatoxin.
Aflatoxin, as we have already said, is a proper first-class carcinogen that is ranked among the high risk factors for liver cancer for many years.
It is also very simple to distinguish, but where the nuts such as peanuts and pine nuts turn yellow or black, the taste is bitter; the surface of grains and corn grows yellow-green mold or is damaged, discolored, wrinkled, etc., do not eat or buy.
In addition, when buying watercress sauce and tofu milk, if you find that the packaging is damaged or the bottle cap is floating, do not buy it.
