Nowadays, the standard of living has improved, people's "pursuit" of fruits is getting higher and higher, and the selectivity is also increasing, but many people have such doubts:
Some fruits look similar, or even almost no difference, but the price is ridiculously different, such as kiwi fruit a pound is only a few dollars, but a kiwi fruit is a few pieces or even a dozen pieces, what is the difference between these "fruits that look like"? Is it worth the "big money" purchase?
1. Kiwifruit and kiwifruit
The difference between domestic and imported
China is the birthplace of kiwifruit, which was later introduced to New Zealand, cultivated and improved, and then sold back to China, and got a "foreign name" - kiwifruit.
Generally speaking, ordinary kiwifruit is green-hearted, needs to be ripe, and soft to eat; while kiwifruit is a yellow-hearted kiwifruit, and hard can also be eaten, without ripening.
In addition to the difference in taste and price, there is actually not much difference in nutrition between the two. Therefore, relatively speaking, the cheaper kiwifruit is more cost-effective.
Nutritional advantages
(1) The king of vitamin C. Each 100g of kiwifruit contains vitamin C up to 100 to 200mg. In other words, eating a kiwi fruit can meet the body's need for vitamin C for a day.
(2) Aids digestion. A new study in New Zealand suggests that kiwi fruit can alleviate the situation of eating big fish and meat. Because the kiwi base unique to kiwifruit can speed up digestion and make protein more easily absorbed.
(3) It is good for cardiovascular disease. Kiwi peel and pulp contact part is rich in pectin, accounting for 1/3 of the fiber it contains, which can reduce the concentration of cholesterol in the blood; in addition, it is a high potassium and low sodium fruit, which is conducive to controlling blood pressure and is good for blood vessels.
Note: People with indigestion and easy diarrhea and allergies should eat kiwi fruit with caution.
2. Pineapple and pineapple, the same species
Pineapples and pineapples belong to the same category, both in flora and encyclopedia. Pineapple spread to Taiwan Province in China during the Qing Dynasty, and the people of Taiwan called it pineapple. That is to say, the names of different regions are different, equivalent to a big name and a small name.
Speaking of which, many people will refute it. The reason is roughly the following two points: when cutting pineapple, there are thorns (eyes) in the pineapple to dig out, leaving a pit, and when cutting pineapple, it is not needed; when the pineapple is eaten, it should be soaked in salt water, and the pineapple is not used.
In fact, this is the result of selective breeding. In order to make pineapples more delicious, agronomy researchers and fruit growers have developed many varieties with different characteristics, some without picking thorns, and some contain less bromelain and are sweeter. The growing environment will also affect its taste to a certain extent.
Tips: Bromelain and biosides in pineapple are easy to cause allergies, and the more effective and thorough way to prevent pineapple allergies is to soak the cut pineapple in boiling water for 2-3 minutes, and the bromelain will begin to degenerate at 45 ° C ~ 50 ° C, and most of them will be destroyed when it reaches 100 ° C.
(1) Anti-accumulation food: Pineapple contains a variety of organic acids and bromelain, eating a piece of pineapple after a big meal will help digestion and prevent accumulation of food.
(2) Improve immunity: On the one hand, pineapple contains a variety of vitamins, minerals, especially rich in vitamin C and manganese, which is good for strong fitness; on the other hand, pineapple is rich in flavonoids and phenolic acid antioxidants, which can resist free radicals, reduce inflammation, and strengthen the immune system.
3, the tip, in fact, is the grape
The skins are thick and easy to peel, soft and juicy, while the grapes are thinner and more difficult to peel, but the flesh is crisper. Although the taste is different, the two are actually a fruit.
The grape family is huge, there are more than 60 kinds of grape plants in the world, and the grape is only one variety of Eurasian grapes, containing basically the same nutrients. However, the cost of growing the grapes and the grafting technology are higher, so the price will be more expensive.
(1) Auxiliary anti-thrombosis. French scientists have found that grapes have a certain effect on preventing thrombosis, which can help reduce cholesterol levels and platelet cohesion.
(2) Auxiliary blood replenishment. Grapes are rich in iron, which is easily absorbed after being ingested by the human body, so for people who need blood replenishment, eating grapes can have a certain auxiliary effect.
(3) Improve fatigue. Grapes contain calcium, potassium, phosphorus, iron and a variety of vitamins, as well as a variety of amino acids needed by the human body, especially suitable for people with excessive fatigue.
(4) Anti-aging. Grapes contain antioxidant and anti-aging nutrients such as resveratrol, anthocyanins, and flavonoids, especially in grape skins that are more abundant than pulp.
The way the grapes are washed
Place the whole bunch of grapes in water, add baking soda + table salt, then add 2 tablespoons of flour or starch, pour it back and forth and wash it with water.
Flour and starch are sticky to water and carry down dirt from the grape skin. As for the white frost on it, it is a sugar alcohol secreted by the grapes themselves, which can be washed off without washing.
Note: Although the grapes are good, the sugar content is high, about 10% to 15%, and even as high as 20%, so do not eat too much at one time, especially for diabetics, it is even more important not to eat more.
Fourth, citrus fruits, two or two hybrids
However, nutrition has its own preferences
Among the major common fruit families, it is difficult to have a more complex species than the citrus family ~ often eaten kumquats, lemons, oranges, oranges, grapefruit, etc. are one of them, and some are obtained by "combining twos and twos". For example, grapefruit and oranges combine to form oranges; oranges and grapefruit combine to produce grapefruit; oranges and oranges produce oranges...
Although they belong to the same category, they still have their own emphasis on nutritional value:
(1) Orange, soothe fatigue. Among them, the potassium and manganese content is considered to be the best. Potassium can maintain the excitability of nerves and muscles; manganese participates in lactic acid metabolism and can help eliminate muscle soreness after exercise.
(2) Oranges, bright eyes and beautiful skin. Oranges are the citrus fruits with the highest carotene content. After carotene is absorbed by the body, it can be converted into vitamin A in the body, which helps maintain vision, antioxidants, skin protection, and enhances immunity.
(3) Grapefruit, low calories. Grapefruit is very suitable for people who need to lose weight, because its calorie and sugar content are low, and it is high in fiber.
(4) Kumquat, which helps regulate blood pressure. Kumquat contains kumquatine, which helps lower blood pressure, and vitamin P enhances the elasticity of the blood vessel wall, preventing blood vessels from narrowing and running poorly.
The kumquat peel also contains kidonyl and syringin, which can also help regulate blood pressure. Patients with high blood pressure can take 5-6 capsules a day.
Note: Citrus fruits contain a lot of organic acids, rinse or brush your teeth in time after eating to prevent damage to your teeth. In addition, do not eat before and after taking the drug, there may be a drug reaction.
