On the way to the bus station in the city, there is a big fruit store, Ding Xuecheng took his grandmother to the fruit store, and popularized fruit knowledge to his grandmother while walking.

"Grandma, it's good to eat more fruits usually, and the immortals in "Journey to the West" don't seem to eat, they all eat fruits."

"Hehe, the myths and legends on TV are all lies. Is it possible that the immortals don't eat at all, but they can live forever? ”

"Whatever, since the gods like to eat, it is better for us mortals to eat it. Fruits are not only rich in vitamins, water and minerals, but also the content of fructose and pectin is significantly better than other foods, and these nutrients are undoubtedly beneficial to human health, especially for the elderly. ”

"Xiaobao knows so much! I heard that eating fruits regularly can delay aging and beauty, is it true? ”

"Grandma, we learned it in science class, and the teacher also asked us to look up information about the role of fruits, and I will tell you about it."

"Food has the attribute of 'four qi', which means that when food enters the human body, it will produce the effect of 'cold, heat, warmth and cold'. If it is neither warm nor hot, nor cold nor cold, it belongs to the 'flat' nature. Some elderly people have a weak constitution, people with a weak and cold constitution have a low basal metabolic rate, less heat production in the body, and their limbs are cold even in summer, so their faces are pale, they are rarely thirsty, and they do not like to touch cold things, including entering the air-conditioned room. Traditional Chinese medicine has always paid attention to balance, yin and yang harmony, so people with a cold constitution should naturally choose warm fruits when eating fruits, such as lychee, longan, guava, cherry, coconut water, durian, and apricot. Chestnuts, walnut meat, etc. On the contrary, some elderly people have a damp and hot constitution, strong metabolism, more heat production, easy to heat, often red face, thirsty tongue, like to eat cold drinks, easy to irritability, often constipation. Such people should eat more cold foods, such as melon, watermelon, pear, banana, kiwifruit, mango, lotus root, tomato, persimmon, water chestnut, melon, cucumber, grapefruit, etc. There is also a category of 'peaceful' fruits, such as grapes, pineapples, papayas, apples, coconut, pears, oranges, watermelon skins, mangoes, olives, ginkgo seeds, plums, etc., which can be eaten by people of different physiques. ”

"How much more do you know about eating fruit?"

"Well, fruit is also a kind of food, and there are sayings of dietary therapy and medicinal diet in Chinese medicine, which are all scientific! Grandpa has been bedridden all these years, on the one hand, there is not enough money for treatment, and on the other hand, I suspect that grandpa has cerebrovascular problems! And some fruits are very helpful for older people who have cerebral infarction. ”

"Oh, tell me about it!"

"Papaya contains more than 17 kinds of amino acids and a variety of nutrients, which can soften blood vessels; Strawberries are rich in vitamins and pectins, which have high clinical value in the prevention and treatment of atherosclerosis, coronary heart disease, and cerebral hemorrhage, and have certain effects on hypertension; Kiwifruit contains more than 17 kinds of amino acids, pectin, tannic acid, citric acid, flavonoids, contains a variety of trace elements, vitamins, especially Vc and selenium are rich in content, long-term consumption, can lower blood pressure, blood lipids and other diseases.

"Papaya, strawberries, kiwi, grandma remembered!"

"Don't worry, there's more! Among fruits, citrus has the highest antioxidant content and prevents blood clots. Regular consumption may prevent cardiovascular disease. Eating walnuts raw, longan meat, and mountain residue can improve heart function. Eating one large apple a day can reduce blood cholesterol levels and prevent blood vessels from hardening. ”

"Walnuts and the three types mentioned above are quite expensive, and citrus and apples are cheaper. Xiaobao, what kind of fruit do you think is good to buy? ”

"Let's buy a little bit of everything, see which one grandpa likes to eat, and buy more in the future." In addition, some fruits do have the effect of delaying aging and beauty, in addition to the above fruits, oranges, pears, grapes, mangosteen, yacon, are also good choices. ”

"Hehe, Xiaobao will tell grandma in detail!"

"The abundance of vitamin C in oranges helps reverse skin damage caused by sunlight and pollution, reduces wrinkles, and improves the overall texture of the skin; Pears are seasonal fruits in autumn and winter, because the dietary fiber in pears is much more than other fruits, so eating it helps to excrete carcinogens in our colon, thereby reducing our chance of developing colon cancer; The antioxidant quercetin contained in apples can improve the overall health of the nervous system, and modern studies have found that apples help protect nerve cells from oxidative stress and reduce the risk of developing dementia; The dietary fiber, potassium, vitamin C and vitamin B6 contained in bananas work together to ensure that the heart is in optimal working condition. Resveratrol, which is abundant in grapes, burns fat particularly well. Researchers at the University of Georgia in the United States found that resveratrol can cause fat cells to break down 2.46 times faster than normal. Mangosteen is a tropical fruit, its flesh is delicate, high nutritional value, can supplement a variety of vitamins and minerals for the human body, in addition to this fruit can also remove cholesterol in the human blood, can avoid them from accumulating on the blood vessel wall, usually the elderly eat more mangosteen, can effectively reduce the occurrence of arteriosclerosis and hyperlipidemia. Yacon is high in calcium, magnesium, iron, zinc, potassium, selenium and trace elements. It can regulate blood, reduce blood sugar, blood lipids and cholesterol, prevent and treat hypertension and diabetes, and has obvious health care effects on cardiovascular and cerebrovascular diseases in the elderly. Yacon also contains 20 kinds of amino acids and minerals and trace elements such as calcium, iron, potassium, and selenium, which can improve the body's immunity when consumed regularly. ”

"Grandma has seen it, Xiaobao knows so much, like an expert on TV!"

"Grandma, the fruit shop has arrived, let's go pick some fruit."

"Well, I bought fruit just in time for the last bus, don't delay too long!"

"Grandma, I'm familiar with fruits, I'll be fine in a while!"

Ding Xuecheng pulled his grandmother to the kiwi countertop first.

"Grandma, the origin of kiwifruit is Wuduhe Town, Yiling District, Yichang City, Hubei Province, where the kiwifruit produced is the most authentic. Hubei written on this brand, I don't know if it's from Duhe Town, so I bought this, choose 3, one for each of us! ”

"Hehe, it's kiwifruit, so I don't care where it's produced!"

Ding Xuecheng acted as a narrator for his grandmother, and every time he went to a fruit table, he said what kind of fruit it was, where it was originated, and where the fruit was authentic.

"Take one and a half of the papaya and eat it separately; Strawberries are out of season, either produced in greenhouses or preserved, just choose a catty; That is a sesame banana, it tastes good, come with a small bunch; Orange, citrus, mangosteen, pear, choose 3; Apples can be stored, buy 2 catties. ”

"Okay, okay, Xiaobao, that's enough~"

"Oh, well, that's all! I took it and weighed it to pay the bill. ”

"So much, I can't finish it!"

"Auntie, help me weigh it."

"Okay, wait a minute!"

……

"Children, a total of 101.6 yuan, I will charge you a whole hundred."

"Well, thank you, give you a hundred!"

"Congratulations to Bobo for completing the 'parent-child interaction' activity task, going to the fruit store with his family, learning about the origin of various fruits, and rewarding 500 points."

"Oh, Beibei, isn't there no mission?"

"Extracurricular tasks are hidden, need to be triggered, and there are still rewards. You should definitely pay attention to extracurricular activities in the future, and try to apply what you have learned in class to your daily life. ”

"I won't forget such a good thing!"
