When you think of healthy and delicious food, what comes to mind first? The answer that many people may give is fruit, but fruits are delicious and healthy. But it has long been a hit area for health rumors. Today Xiaobian will come to you to dispel these rumors about fruits. This content is recommended to be transferred directly to family and friends, after all, good things must be shared with family and friends.
Debunking rumors
The first thing to say is the grapes, I believe many people think that the white frost on the grape skin is a pesticide residue, so it must be washed or peeled before eating. In fact, the white frost on the grape skin is not a pesticide, but a substance secreted by the grape itself, and its main role is to reduce the evaporation of the grape's own water and effectively prevent the infection of germs. These white creams are not harmful to the human body, and if you buy grapes with this white frost, it means that it is very fresh.
Fresh grapes
If you are worried about pesticide residues on the epidermis of grapes, you can wash them according to this method: first cut the grapes into small bunches, then rinse the surface with water for 30 seconds, then soak them in a 2% baking soda solution for ten minutes, and finally take it out and rinse it with water to eat with confidence.
Someone asked the grape skin, is it true that grape seeds can antioxidant whitening? The answer is true, but only if you eat enough.
Grape seeds contain proanthocyanidins, which can play an antioxidant role. But at the same time, it can also reduce the activity of digestive enzymes in our body, which is very detrimental to the digestion of the human body.
Grape seed extract proanthocyanidins
Resveratrol in grape skins can indeed be whitened, but it contains 50 to 100 mg per kilogram in grape skins, and 1500 mg per day may be effective, equivalent to eating 15 to 30 kg of grapes. According to the amount of fruit we usually eat, it is completely insufficient, and the most important thing is that the grape seeds and grape skins are difficult to swallow.
banana
The second one we talk about is bananas. There is a question about it that everyone is very familiar with, that is, whether eating bananas can relieve constipation. Most people think that bananas are rich in dietary fiber and can relieve constipation very well, so people often call it "laxative little expert".
constipation
In fact, the dietary fiber of bananas is not very much, and fruits such as cantaloupe, guava, and avocado are rich in more dietary fiber than it, and the most abundant dietary fiber is green leafy vegetables. Here it is recommended that constipated netizens eat more fresh green leafy vegetables. Not only that, underripe bananas may also aggravate constipation, and everyone must pay attention when eating bananas.
Many friends ask whether the blackened banana can still be eaten? If there are black spots on the banana peel, it is because the banana epidermal cells are oxidized, and a large area of black will appear in the epidermis over time. If the pulp is not affected after tearing, the banana can still be eaten. If the flesh becomes black, and even the flesh sticks, it means that the banana has begun to rot, it is recommended that everyone do not eat, throw it away, do not feel pain. After all, the body is more important.
apple
The third we talk about apples, apples are also many people's favorite fruits, sometimes apples will have a layer of wax on the surface when they buy them, is this layer of wax harmful to the human body? In fact, the wax on the apple is generally divided into two kinds, one is the natural fruit wax secreted by the apple in order to defend against insect pests, and the other is to avoid apple rot, artificially marked with food-grade fruit wax, these two waxes have no harm to the human body. However, apples have more pesticide residues, so it is best to wash or peel the grapes before eating.
Apple wax
Some elders think that eating apples at night is equivalent to taking drugs, and they think that eating apples at night will remain in the stomach to produce toxins. Xiaobian is here to responsibly tell everyone that this rumor is false! As long as it is a normal person, whatever you eat will be digested, so it is impossible to produce toxins.
tangerine
Fourth, let's talk about oranges. Can the white silk on the orange be eaten? The white silk of an orange is called an orange drop, which is a vascular tube of an orange, just like a human blood vessel, responsible for transporting various nutrients such as water and sugar. Their main components are ductal cells and fibroblasts with thick cell walls, which can be eaten, but the taste is not good, and many people do not like it. However, in the view of Chinese medicine, the bureau has the effect of coughing up phlegm and communicating. If you can accept its taste, you can eat it together.
The size of the orange umbilicus
Are oranges divided into male and female oranges sweeter? In fact, there is no scientific basis for this statement. The so-called orange male and female is to see the size of the umbilicus at the bottom of the fruit, some people call the large umbilicus as the female, and the small umbilicus as the male. But in oranges, there is no obvious boundary between the size of the umbilicus, it is difficult to really divide the male and female, and there is no evidence that the size of the umbilicus can affect the taste of the fruit.
Kiwifruit and kiwifruit
Which would you choose between kiwi or kiwifruit? Is it true that kiwifruit has a higher nutrient content than kiwi fruit? In fact, there is no difference between kiwi fruit and kiwifruit, they are the same fruit, and the nutritional effect is almost the same. It's just that yellow heart kiwifruit contains more lutein, while green heart kiwi fruit contains more chlorophyll, so the color presented is different.
After some improvements, the sugar content of yellow heart kiwi fruit will be higher, and many people eat kiwi fruit for its name of "King of Vitamin C". In fact, this is also a rumor. The vitamin C content of kiwifruit is 62 mg per 100 grams. Fresh dates and guavas have a higher vitamin C content than it. Not only that, many vegetables also have a higher vitamin C content than kiwifruit, such as wild amaranth, peppers and so on. Therefore, although kiwi fruit has a high content of vitamin C, it is not the true king of vitamin C.
Everyone also knows which fruit rumors, you can leave a comment message to tell me.
