Kyushu space common bottled water pH evaluation
Although the pH values ​​of the various waters are different, we can clearly see a trend in which the pH of mineral water is higher than that of pure water, while the pH of mineral water is the lowest. The performance of Watson's water makes people fall below the eye. The pH of mineral water and pure water are rubbed against national standards. Only one pH value makes people doubt that the slimming price it represents comes from. Is it a bottle? Although the sun god recently sold big ads, the price is far more than the ordinary pure water, but unfortunately it is difficult to know the reason why it bought this price.
I. Introduction
In 2006, Nongfu Spring launched a great advertising campaign to promote the difference between its natural aquatic products and general mineral aquatic products: natural water, weak alkaline. As the advertisement progressed, a lot of opposition voices appeared. But consumers' doubts have not disappeared with the slogan of propaganda. Instead, more people are paying attention to the pH that has never been noticed before. The new drinking water standard was officially implemented on July 1 this year. Although it has little to do with the bottled water called “beverage†in the industry, we can’t help but the water that these people actually use as drinking water. care.
So what is the pH? In fact, the pH is chemically used to measure the activity of hydrogen ions in a substance. pH>7 is alkaline, pH=7 is neutral, and pH<7 is acidic. The pH value in healthy people is between 7.35 and 7.45, that is, the pH of human body fluid is constant and weakly alkaline, in order to maintain normal physiological functions and material metabolism. In general, the pH is higher than 7.45, called alkali poisoning; below 7.35, it is called acidosis. (detailed)
Nowadays, people often eat big fish and big meat. These foods are all acidic foods. If you eat too much, it will make the body fluids acidosis. The acid-base theory of the past few years comes from this, and the theory also establishes a close relationship between acidic and sub-health. After a series of propaganda of Nongfu Spring and Professor Li Fuxing's knowledge of water health, “drinking water should drink weak alkaline waterâ€, this view has not been officially recognized and indeed has an impact on consumers.
The 39 Health Network evaluation room included the common 24 brands of bottled water for pH measurement. These 24 brands of water are involved in three major categories of natural water mineral water, purified water and mineral water. I hope that everyone can understand the healthy drinking water.
