This summer, the beverage market is alkaline water and heat.Expert: Not applicable to everyone

"Natural weak alkali", "pH8.8 natural alkali", "easy absorption" ... Entering summer, hydration is a top priority. The reporter visited the market and found that as consumers have improved the quality of mineral water, alkaline water has become more and more darlings in citizens' shopping carts. Dai Chun, an intermediate nutritionist at the Nutrition Department of Nanjing First Hospital, said that although alkaline water has the effect of alleviating gastric acid, not everyone is suitable for drinking alkaline water.

Reporter visit: a variety of alkaline water prints the pH value on the outer packaging

On the morning of June 16th, the reporter visited a number of physical supermarkets and found that soda water had occupied the "half of the country" where direct drinking acetic frames. In the Yonghui Supermarket in Longhu Tianjie, Hexi, the reporter saw the "weak alkali" of the packaging of many soda drinks. Among them, the pH value of "Yineng soda water" is 7.6 ± 0.4, the pH value of "Name Renzu Water Beverage" is 7.8 ± 0.4, and the unit price is 2-2.5 yuan/bottle.

Open the Hema APP, the reporter found that there are Hema brand alkaline natural mineral water for sale. The "pH9.3" of the blue large font is particularly conspicuous on the transparent bottle packaging. The reporter noticed that the "pH value 9.3 ± 0.6, and the silicic acid 40-80 mg/L" was marked on the packaging. The ingredient table is natural mineral water. The main ingredients of water quality include spoiler, total solid solid, potassium, sodium, calcium, and magnesium. The water source address is the underground well in Yangzonghai Scenic Spot.

Subsequently, after the reporter searched alkaline water online, the multi -brand weak alkaline water and soda drinks appeared. Among them, a natural soda water that labeled PH8.8+is as high as 7 yuan/bottle, and the capacity of each bottle is 580ml. The customer service said that this pure natural soda has sugar -free qi and no fat, and long -term drinking helps to relieve uric acid and stomach acid. Another natural soda water has put the pH data table on the outer packaging of the box and indicates "natural weak alkali". The unit price is 2.7 yuan/bottle, and the capacity of each bottle is 440ml. When the reporter proposes to be different from ordinary mineral water, the customer service told reporters that natural soda is natural mineral water, but natural soda needs to meet the pH value of 7.6-9.0 weak alkali, neutralize the natural small molecule of uric acid, so that the human body is more likely absorb.

Packaging regulations: Product names must not be marked with "small molecular group water"

The so -called alkaline water refers to the "pH> 7 water". As for whether alkaline water can regulate the acid -base constitution in the human body, the answer is negative. Because the pH value of the human body is stable between 7.35-7.45, and it is impossible to "sour" at will under normal circumstances. Dai Chun, a middle -level nutritionist at the Nutrition Department of Nanjing First Hospital, told reporters that the human body can quickly discharge many acidic ingredients through the respiratory system, and the kidney itself can excrete excess organic acid through urine, so the acid and alkali constitution of the human body can be complete The adjustment mechanism does not need to increase the pH value by drinking alkaline water.

For the packaging of alkaline water, the "National Standard Packaging Drinking Water" (GB 19298-2014), which was implemented in 2015, had already stipulated that the name of the product name of the packaging and drinking water must not be marked with "activated water", "small molecular group water" "Functional water", "energy water" and other unscientific content. The name of the packaging and drinking water should be true and scientific, and must not be named the packaging water with one or several types of ingredients other than water. The label signs of packaging drinking water shall comply with the provisions of the "Food Safety Standard Food Packaging Packaging General" (GB 7718). It should be clear, eye -catching, and lasting, so that consumers are easy to identify and read when purchasing.

Doctor answers: It is not recommended that children drink too much alkaline water

But is the alkaline water marked "high price" really IQ taxes? Dai Chun introduced that for people with more gastric acid secretion and high uric acid content, drinking sodium bicarbonate alkaline water will really have a certain effect on alkaline urine or neutralized gastric acid, but it is far from clinical medication. Alkaline water does not replace drugs. "Alkaline water helps to relieve stomach acid and may reduce appetite, but children have the need for growth and development, so it is not recommended that children drink too much alkaline water." Dai Chun added.

Whether it is alkaline water, acidic water or ordinary mineral water, the safety of drinking is the most important. Summer is coming, people sweat more, and it is also very important to replenish water in time. What water to drink? How much water should I drink? Dai Chun said that daily drinking water first chose boiled water. Generally speaking, adults' daily drinking water is about 2000 ml, but for sweating more, especially some outdoor workers, it is recommended to increase drinking water. It is a reasonable range of 3000 ml to 5000 ml a day. "You can drink more cool and white in summer, or bring some salt ingredients in salt water, which can supplement the salt loss of sweat in the body to achieve the effect of heatstroke prevention."
