It is globally recognized that super fruit can be eaten even in the skin, which is very difficult to grow and few people have ever eaten it.

With the development of modern society, people's living standard is much higher than before. Therefore, in the matter of "eating", modern people pursue not only having enough to eat, but also eating healthily. Take eating fruit as an example. In the past, people used to say, "an apple a day keeps the doctor away from me." they highly praised the health care effect of apples, but now, as a popular fruit, apples are far from meeting people's needs. This is not to say that the nutritional value of apples is not high, and its nutrition does not seem to be so comprehensive, so in recent years, people have been hoping to eat more nutritious fruits, which can supplement a lot of nutrients by eating a few fruits. This kind of fruit is not non-existent, it has a high reputation all over the world, and it is also recognized as a "super fruit".

This fruit is a blue berry called blueberry. It is native to North America and is the fruit of a low shrub. It was originally a very sour berry, but after artificial cultivation, the taste became very sweet and became a best-selling fruit on the market. Blueberry, as the name implies, is blue in appearance, which is very different from the color of the fruit we usually eat. Although it is not big, it is very nutritious. Its pericarp is wrapped in a layer of white fruit powder. Don't wash it off when you eat it. You'd better eat it with the skin.

Blueberry is recognized as a "super fruit", which is inseparable from its high nutrition and low calorie. Not to mention protein, vitamins and so on, what is most worth mentioning is its special application ingredients: anthocyanin, polyphenols, rosewood. The anthocyanin content in blueberry is extremely high, and the variety is rich. Anthocyanin is a kind of pure natural active substance, which is very good for eyesight. It can promote the regeneration of rhodopsin in the retina, prevent myopia and relieve eyeball fatigue. In addition, blueberry contains polyphenols, red sandalwood stilbene has a strong antioxidant effect, has an inhibitory effect on some diseases, it can be said that blueberry is a very comprehensive health fruit.

It is precisely because of these effects that blueberries have been identified by the United Nations Food and Agriculture Organization as "one of the five healthier foods for mankind". But although blueberries are delicious, they are extremely difficult to grow. First of all, they are picky about the environment. Blueberries should be planted in acidic soil with a PH value of 4.5-5.5, and the soil should be very moist because it is not resistant to drought. Then it is suitable for growing in places with low temperatures, but not in the tropics. Finally, its yield is relatively low, the first three years of planting output is very low, after entering the fifth year, the yield per mu will be relatively stable, the yield per plant is about 3-6 kg.

Blueberry is a kind of berry, which is destined to be undominant in transportation. It has a short shelf life and is not resistant to extrusion, so blueberries shipped to the market are very expensive. This also leads to its high price, a small box of 200 grams, can be sold for 30 yuan, taking the high-end route. This also causes few people to eat it, my friends, have you ever eaten it?
