1, precautions for eating grapes
First, rinse thoroughly.
Essential fruit reminds you that when you buy grapes in a fruit shop, you must clean them thoroughly from beginning to end. Many grapes were sprayed with pesticides during their growth. Therefore, there may be residual dirt on the grape skin, and in the process of eating grapes, sometimes it is inevitable that your mouth will touch the grape skin, which is not conducive to your health. Tell everyone a good way, soak the grapes in salt water for 10 minute, and the dirt left on the surface will be cleaned very clean.
Second, you can't eat it with milk.
As we all know, grapes are rich in vitamin C, and some ingredients in milk will react with vitamin C contained in grapes, causing harm to the stomach. At the same time, taking it can also cause diarrhea and vomiting in severe cases. So, honey, don't mix milk with grapes.
Third, rinse your mouth and protect your teeth
Fermented sugar contains ingredients that are harmful to teeth, while some grapes contain a variety of fermented sugar substances, which are very corrosive to teeth. Therefore, if you don't rinse your mouth after eating grapes, grape residues in your mouth are likely to cause dental caries.
Fourth, after eating the grapes, bring the seafood.
People in coastal areas have the habit of eating seafood, but fruits such as grapes, hawthorn, pomegranate and persimmon can't be mixed with seafood. Once eaten together, symptoms such as vomiting, abdominal distension, abdominal pain and diarrhea will occur. This is because these fruits contain tannic acid, and tannic acid will solidify and precipitate when it meets protein in seafood, forming indigestible substances, so this is worthy of our attention.
5. Don't drink water after eating grapes
If you drink water immediately after eating grapes, it is easy to cause diarrhea immediately. This is because grapes themselves have the effect of relaxing bowels and moistening intestines. Drink water immediately after eating grapes. The stomach will dilute the gastric acid before digesting and absorbing water. Grapes, water and gastric acid are rapidly oxidized and fermented, which accelerates intestinal peristalsis and produces diarrhea, so remember, remember.

3. Grape purchasing skills
1. Variety selection: There are many kinds of grapes, and the selection is dazzling. How to choose different varieties? The key is to see when you buy grapes. Now, in July and August, a large number of grapes are off the shelves. When you pick Kyoho, Hongti and Rose fragrance, you can choose these kinds. Although qingti is also on the market in large quantities now, it has poor taste and low sweetness, so buy as little as possible; Seedless dew tastes very sweet, and it is also a variety that is listed more now. Some people like to eat manna, which can be bought. When there are few giant roses on the market and the taste is not the best, try to buy them. The following pictures are in order: red rose, seedless dew, rose fragrance and giant peak.
2. Choose grapes that suit your taste: The taste of grapes is mainly related to its variety and maturity. For generally ripe grapes, Kyoho is sweet and sour, and some people accidentally buy Kyoho, which will be sour before it is ripe. Red raisins are also sweet and sour. Compared with Kyoho, red raisins are sweeter, and people who like sweets may buy more red raisins. Rose fragrance has thick skin and many seeds, and it always vomits when eaten. It tastes sweet and sour, and it is my favorite. The sweetness and sweetness of green extracts are relatively low, which people don't like; They are all sweet, and they are characterized by no fruit, so they are happier to eat. Personally, I just don't like him. He's not sour at all.
3. Choose fresh grapes: All varieties of grapes have a common feature, that is, the fresher the better. How to choose fresh grapes? Fresh grapes have some characteristics: ① There is a layer of frost on the surface of fresh grapes, which will fall off when touched by hand, so grapes without frost may be picked and kept, and all the frost will fall off. What's more, green-skinned grapes can't see hoarfrost, so this method is not applicable. (2) The stems of fresh grapes are tough, the fruit stalks and fruit grains are firm, and the common fruit stalks and fruit grains that have been stored for a long time are crumbling;
4. Identify rotten grapes: Many times the grapes sold in supermarkets are packaged, such as plastic wrap. It is difficult to tell whether the grapes are bad at this time. But we can also pull the fruit through the plastic wrap to see if it is firm between the fruit stalk and the fruit grain. If it is broken, it may be that the fruit stalk begins to rot; Besides, you can smell it. Grapes that start to rot will produce the smell of alcohol.
5. Choose full fruit: Of course, it doesn't mean that the bigger the fruit, the more delicious it is, because personally, small-sized rose fragrance is much more delicious than large-sized ping-pong grapes. However, of course, the bigger the grapes on the same bunch, the more delicious they are, so when choosing grapes, you should pick grapes with much bigger fruits on the same bunch.
6. Choose the compactness of the fruit: Generally, the denser the fruit, the richer the nutrition, and the undernutrition will grow loose. But red grapes are much looser than other varieties of grapes, so when you compare the fruit compactness, you should pay attention to comparing the same kind, and don't compare the fragrance of red grapes with that of roses.
7. Weigh the ear: This is also a common method for selecting grapes. The heavier the two bunches of grapes, the better. But there is no comparison between different varieties.
