"Two-cover salt" rule eats less salt in the whole family
Eat less salt equals calcium
“China is a country with a high salt diet and ranks first in the world in terms of salt use.†Li Changping, dietitian of the Department of Nutrition of the Beijing Hospital of the Ministry of Health, told the “Life Times†reporter that when people mentioned salt, people used to think of taste problems but they did not Diseases are linked together. There are 160 million hypertensive patients in China. Excessive salt is one of the important causes of high blood pressure. The World Health Organization recommends that the daily salt intake of healthy adults should not exceed 5 grams, including the amount of salt intake through various channels (soy sauce, pickles, monosodium glutamate, etc.).
Recently, British scientists also found that the more salt intake, the more calcium in the urine, the worse the absorption of calcium. This means that eating less salt is equivalent to calcium. They point out that eating less salt is the most economical way to supplement calcium, and it is also the most beneficial method for health.
Clever use of caps to limit salt
Wang Yi, director of dietetic nutrition department of Guang'anmen Hospital of China Academy of Chinese Medical Sciences, said that Chinese people have used more salt for a long time to make the taste paralyzed, causing the amount of salt to be further away from the health index. The World Health Organization limits the daily recommended salt intake to 5 grams. Although it may not seem realistic in the short term, everyone should be aware of this health index. Slowly adjusting the palatal sensation, the taste sensitivity can be gradually improved.
Salt restriction must first be a good "entry off", that is, cooking should be minimized salt and salt seasonings, here, several experts to teach you some tips.
Wang Yi said that in addition to using a limited salt spoon, everyone can also grasp the "two-cover salt" rule. Just start eating beer bottle cap salt (not more than 10 grams) every day. After adapting, replace it with a toothpaste cover salt every day, about 4.5 grams.
When cooking, season with soy sauce, bean paste, sesame, or flavor with onions, ginger, garlic, and other spices. The salt content in 5 grams of soy sauce and 20 grams of soy sauce is equivalent to 1 gram of salt, and the dish made has a better taste than salt.
Northerners eat salty aromas for their daily diet, and they can properly improve their taste and replace saltiness with sweet, sour and spicy flavors. For example, the use of sucrose to cook sweet and sour flavor dishes, or vinegar with cold dishes, can make up for the lack of salty taste, but also promote appetite. Chris believes that natural sour lemons, oranges, tomatoes, etc. can be used.
You can use the strong flavor of the vegetable itself, such as tomatoes, onions, mushrooms, etc., and cook with a light taste of food, such as tomato scrambled eggs.
The Network Video Recorder 4K, also called the NVR 4K/ 4K HD NVR/ 4K NVR Kit/ NVR 4K CCTV/ NVR 4K System, means that this DVR has the resolution of 4K, 4096x2160, about 8.8 million pixels, which can achieve the movie level image quality, which is equal to more than four times the current top level 1080p resolution. As for 4K, the data volume of each frame has reached 50MB, so both the decoding playback and the editing require the top level configuration machines which also means the ultra-high-definition resolution and the high price.
So what is the Frame?
The Frame is the smallest unit of the single image in video/animation, which is equivalent to every frame of lens of a film. A frame is a still picture, and successive frames form an animation, such as a TV animation. We usually call the Frame the number of frames that pictures transmitted in 1 second. We can also be regard the Frame as that how many times the graphics processor can refresh per second, which is usually expressed by fps (Frames Per Second), and it can be called the Frame Rate. Each frame is a still image, and the displaying frames in the rapid succession creates an illusion of motion. The high frame rate can achieve smoother and more realistic animation. The more frames per second (fps) there are, the smoother the displayed motion will be.
So what is the Frame Rate?
The Frame Rate, also be called the frame frequency, is expressed in Hertz (Hz) and it is the frequency (rate) of the bitmap images(whose unit is frame) that continuously appear on the display. This term also applies to the films, the video cameras, and the computer graphics and motion capture systems.
What about the relationship between the Frame Rate and the Human Vision?
The time sensitivity and resolution of human vision vary, according to the types and characteristics of visual stimuli, and differ between individuals. The human vision system can process 10 to 12 images per second and perceive them individually, and the higher Frame Rates are considered the motions.
Generally speaking, when the Frame Rate is higher than 50 Hz to 90 Hz, most research participants believe that the modulated light (such as a computer monitor) is stable, and the sense of stability of this modulated light is called the flicker fusion threshold( when the modulated light is non-uniform and contains an image, the flicker fusion threshold can be much higher, perhaps hundreds of hertz). As for the image recognition, it has been found that if people need to recognize the specific images in an uninterrupted series of different images, each image should last 13 milliseconds at least. And the persistence of the human vision sometimes may cause a very short single millisecond visual stimulus, and the duration will be from 100 milliseconds to 400 milliseconds. Very short multiple stimuli are sometimes considered as a single stimulus. For example, a 10-millisecond green flash first, then a 10-millisecond red flash followed, under this condition, the they would be perceived as a single yellow flash.
Well, I hope that my introduction about the Network Video Recorder 4K and the Frame Fate could help you know more about this video monitoring field.
