Can ripe bananas and waxed apples be eaten?
1. Is it true that these 3 fruits have been included in the "carcinogenic list"?
In life, we often hear the news that certain foods can cause cancer, which makes many people have a sense of fear of these foods, and even directly pull them into the blacklist and never dare to eat them again, but do these foods really cause cancer?
1.Ripe bananas.
Some people say that bananas are unripe when they are first picked, but when they reach the hands of consumers, they are already ripe, which is caused by a lot of harmful substances added in the middle, so eating bananas can cause cancer.
But there is no scientific basis for this claim, and bananas do need to be picked before they are fully ripe, which helps with transportation and preservation.
Later, to make the bananas edible, ethephon is used to ripen them. However, ethephon is a very safe and commonly used plant growth regulator, which is used to promote fruit ripening, and is very commonly used in ripening fruits such as bananas and mangoes.
Bananas produce a lot of ethylene in the natural ripening process, and the purpose of using ethephon on unripe bananas is to let the ethylene gas emitted by them ripen the bananas, and at the same time let the bananas produce endogenous ethylene by themselves. During the whole process, no harmful chemicals are produced, and naturally there is no carcinogenic.
2.Waxed apples.
There was once a widely circulated ** on the Internet, where netizens scraped off a large layer of wax from the surface of apples, and used this to warn people that eating apples is tantamount to eating wax, which will threaten health.
In fact, apples themselves secrete a layer of wax to protect themselves, but this layer of wax is relatively thin and difficult to distinguish.
After the apple is picked from the fruit tree, it needs to be sorted, cleaned, etc., so that the wax secreted by the apple is easily destroyed, in order to prevent the apple from being invaded by microorganisms and lose water, and at the same time, in order to extend the shelf life of the apple, another layer of wax will be applied to the apple.
This operation is in line with national standards, China's "Food Additives Use Standards" clearly stipulates that fruit wax and carnauba wax are edible. However, some people are more reluctant to eat this taste, so it is completely possible to peel it and eat it again, which will not affect health.
3.Frozen fruits.
It is rumored that the nitrite content in frozen fruits will greatly exceed the standard, which is very bad for people's health after ingestion, and can even cause cancer, is this true?
The claim that fruits are prone to nitrite after freezing is not credible. The nitrate content in the fruit is very low, and even when converted into nitrite, the content is not high, and there is no risk of cancer.
Xie Lingli, deputy chief physician of the Department of Gastroenterology of the Yangtze River Shipping General Hospital, pointed out that the nutritional value of most frozen fruits is not as good as that of fresh fruits, because the cells will be destroyed by ice crystals during the freezing process, and the water in the cells will also run into the gap, making the fruits dehydrated.
Although it is not carcinogenic, there are certain safety hazards, and the environment in the refrigerator cannot be guaranteed to be completely safe when freezing fruits, and it is easy to cause diarrhea, nausea and other symptoms after ingesting fruits contaminated with bacteria.
It is not recommended to consume a large amount of frozen fruits on a daily basis, and those who really like to eat them are recommended to store them in separate packages each time they are frozen to avoid contamination of the fruits.
Second, the real risk of carcinogenic is this fruit.
Many people see a small piece of fruit moldy or rotten in their daily life, and they will feel a pity to throw it away, and they will remove the moldy part and continue to eat it. As everyone knows, this behavior is very dangerous.
Because after the fruit is moldy, there will be a lot of mold growth inside, even if the moldy part is removed, other places that are not visible to the naked eye are likely to have been contaminated.
The rotten fruit is likely to contain aflatoxin, which is a very toxic and carcinogenic substance, which can cause poisoning after ingesting a small amount, induce nausea, vomiting, diarrhea and other uncomfortable symptoms, and even induce cancer in severe cases.
If you encounter moldy fruits in your daily life, you must discard them in time, and don't lose a big one because of a small one!
3. Is it better to eat fruit before or after a meal?
In fact, there are a lot of debates about the food of fruits, some people say that it is good before meals, some people say that it is good after meals, which time is better to eat?
Under normal circumstances, we don't need to deliberately worry about eating fruit before or after meals, as long as there are no uncomfortable symptoms after eating.
However, for some people with poor digestive function, it is still recommended to eat fruits after meals, 1 to 2 hours after meals. For some people who need to control their weight, they can eat some fruit before meals, which can make the body feel full and reduce the amount of food intake.
4. How to eat fruits correctly? Keep 4 points in mind.
Although the fruit is good, there are also a lot of precautions when eating, and these four things must be paid attention to.
1.Eat 1 or 2 fruits a day.
The dietary guidelines recommend that the daily intake of fruits should be kept at 200 350g, and if this amount is calculated, the daily intake of 1 2 fruits can be achieved.
2.Don't eat too many high-calorie fruits.
Most fruits are not very high in calories, but there are some special circumstances, such as durian and avocado are very high-calorie fruits, and the amount of these two fruits should be controlled daily.
3.Special groups of people should pay attention to eating fruits.
For people who are prone to diarrhea, they should pay attention to eating less kiwifruit, dragon fruit, strawberries and other fruits with fine seeds, otherwise it is easy to aggravate diarrhea, and these fruits are very suitable for constipated people;
People with excessive gastric acid secretion should pay attention to avoid acidic fruits such as hawthorn, bayberry, and lemon; Diabetic patients should pay attention to staying away from fruits with high glycemic index, such as watermelon, jujube, etc.
4.You can't eat fruit alone for a meal.
Many ** people will take fruits as a meal, but this practice is not scientific, the nutrients contained in fruits are relatively limited, and eating only fruits for a long time can easily lead to unbalanced nutrient intake in the body, which is not good for health. And the sugar content in many fruits is not low, and eating a lot of fruits will make the body fat.
As fruit is one of the foods we often eat every day, we must learn to screen rumors about it, and don't affect our lives because of some unfounded rumors.
