It is not difficult to find bananas in Japan as they are sold in any supermarket or convenience store. Photo: ABC. However, bananas are still a rare fruit in the land of the rising sun, because 99.98% of bananas in this country are imported. Only 0.02% of the bananas on the market are grown locally.

The type of banana grown in Hokkaido is called 946 and the price is not cheap. Photo: Soranews24 The price of a 946 banana is 1,080 Yen, equivalent to 230,000 VND, 20 times the price of an imported banana in Japanese grocery stores. Photo: Soranews24 Even a box of three bananas is more expensive than buying three individual fruits because there is also the cost of packaging as a gift. Photo: Soranews24 Accordingly, a box is 4,860 Yen (about more than one million dong). The price surprised many people. Photo: Soranews24 Japan’s 946 bananas are quite large in size, equivalent in length but “fatter” than bananas imported from other countries. Photo: Soranews24 Like most fruits in Japan, banana 946 is grown with a clean process, without the use of pesticides and chemical fertilizers. They have a sweet but not overpowering taste, with just the right amount of moisture and scent. Photo: Soranews24 In particular, banana peels are thinner than regular bananas and are described as “thin enough to be eaten”. Even 946 banana peels can be sautéed like the traditional Japanese vegetable kinpira gobo. Photo: Soranews24 Video: 9x boy is passionate about growing clean bananas Source: VTV24

Grape is a genus of berries, one of the oldest plants on earth, and one of the earliest fruit trees cultivated by mankind. As early as “Compendium of Materia Medica” and “Shen Nong’s Materia Medica”, there are descriptions and recognition of grapes, and modern people have also developed many nutrition and health products related to grapes. It can be seen that people pay more attention to the nutrition and health benefits of grapes. Increasingly.

1. Nutritional value

Each 100 grams of grapes contains 10.3 grams of carbohydrates and 0.5 grams of protein, as well as various vitamins and organic acids. The total acid content in grapes reaches 0.3-2.1%, which contains malic acid, oxalic acid and tartaric acid unique to grapes. Tartaric acid is a carboxylic acid that exists in many plants and is also one of the main organic acids in wine. The organic acids in grapes can appetite and promote digestion, as well as chelate and reduce, and promote the absorption of a variety of minerals.

2. Great effect of small grapes

People generally eat more grape pulp, but in some studies, we have found that Grape skins, grape seeds , Its nutritional value is higher than that of grape pulp, and its health effect on the human body is also stronger.

Grape skin is rich in a kind of polyhydroxy phenolic compound——— Resveratrol as well as tannins and anthocyanins , These ingredients can play an important health effect on human health. Resveratrol is a natural antioxidant that can reduce blood viscosity, inhibit platelet coagulation and relax blood vessels, and keep blood flowing. It has the effects of anti-atherosclerosis and coronary heart disease, lowering blood fat and enhancing immunity. Tannin is another important substance in grape skin. Tannin is an acidic substance, mainly derived from grape skin and grape seeds. Tannin has the functions of sun protection, whitening, anti-allergic and anti-aging.

Grape seeds are rich in Proantho Cyanidins Usually called OPC, it is an antioxidant, mainly found in the epidermis and seeds of plants. It is the key to increasing the potential of antioxidants in the body, protecting the body from oxidative damage and delaying aging. Antioxidants are substances that inhibit free radicals. These molecules can cause protein cell membranes and even DNA mutations, causing cancer and other chronic diseases. Antioxidants can scavenge free radicals, thereby preventing the occurrence of chronic diseases and cancer.

Through the above introduction, everyone has a better understanding of grapes, and it is recommended that you “eat grapes without spitting out grape skins”. More nutrients can be taken in grapes with limited consumption, and the effect of health care can be better exerted.

It is understood that the meaning of “two skins” generally refers to the separation of two things that originally have a necessary or dependent relationship with each other, and they exist separately. It is often used to compare things that are originally closely related but are separated from each other and are not related. situation.

However, Wei Leping said that the “two skins” of the current status of the cloud and network are mainly reflected in the following four aspects: First, the low efficiency of cloud network service provision, the lack of unified and flexible capability provision and scheduling of cloud network resources, and the slow opening and adjustment of cloud network products and services ; The second is the high development cost of cloud and network services, the independent construction of the cloud and the network, the information is not open to each other, the mutual calling interface is not standard, and it is difficult to form an overall view of the cloud; Management, relying on work orders, poor coordination, low level of data sharing, and difficult end-to-end management; fourth, cloud network security is a big challenge, cloud and network each have many systems, large scale, complex technology, and end-to-end cloud network security assurance The challenge is big.

Wei Leping believes that cloud-network integration will be divided into three stages of development: the first stage is the collaboration phase (2021-2022), the cloud-network infrastructure layer is “connected”, business automation is opened and loaded, and one-stop cloud-network ordering ; The second stage is the integration stage (2023-2027), the logical architecture and common components are converged, resources and capabilities have a “physical response”, cloud network capabilities are issued and dispatched uniformly; the third stage is the integrated stage (2028-2030 Years), breaking the technical boundaries of cloud and network, the physical and logical layers produce “chemical reactions”, cloud network resources and services have become standard parts of the digital platform. Among them, each stage has four dimensions of measurement (resources and data, operation management, business services, capability opening).

“The development principle of cloud-network integration is: the network is the foundation, the cloud is the core, the network moves with the cloud, and the cloud-network is integrated.” Wei Leping said: Cloud-network integration will eventually move towards cloud-network edge-end integration. The goal of cloud-network integration is to fully realize the cloudification of the network, cloud-network integrated operation and maintenance, and process integration. The difference and isolation of the three major resources of computing, storage and network are no longer visible; the ultimate goal of cloud-network integration must be reflected in the user experience To this end, the end-to-end cloud network edge-related resources must be manageable, visible and controllable; the three major resources of bandwidth, storage and computing should also be intelligently, efficiently and reasonably allocated and deployed on the cloud network edge. , To achieve the best end-to-end resource configuration, not just the best configuration between cloud and network. Of course, this evolutionary path is long and may last for more than ten years, but it is also an inevitable development trend.

At the same time, cloud-network integration also requires an open environment. Wei Leping said that the use of open source technology is an important measure to achieve an open environment; to break through manufacturer-specific hardware restrictions, promote competition, and reduce costs; provide a standardized basis for differentiated manufacturer solutions; the huge potential advantages of open source technology include the open source environment Under the circumstances, it is possible to use lightweight containerized open source software. The most popular one is Kubernetes, which can run multiple applications on a single server. Because Kubernetes is decoupled from the underlying infrastructure, it may span DC, core networks, and networks. It is easier to generate and deploy services on the edge, and Kubernetes is conducive to enabling and catalyzing the realization of cloud-native architecture. The goal is to gradually form a multi-vendor open cloud network environment based on open source. C114 Communication Network Li Ming
