Types of Drinking Water

Natural Water

Originated from wells, mountain springs, reservoirs, lakes, underground springs, or alpine glaciers.

Natural mineral water

Water naturally gushing deep underground or collected by drilling, containing a certain amount of minerals or trace elements.

Drink pure water

Originating from the surface, underground or public water supply system, it does not contain minerals or trace elements.

Other drinking water

Refers to packaged drinking water other than natural water, natural mineral water, and drinking pure water. A certain amount of minerals can be added manually.

Water and Life Health
Drinking Water is Closely Related to the Health of Human Life
Water content in the human body
With increasing age, the water content in the human body will gradually decrease. The embryonic water content can reach 98%, the average fetus at 3 months is 91%, the average at 8 months is 81%, and the average at newborns is 80%. After 10-16 years of age, it gradually reaches adult levels. Water content is 50% for men over 60 years and about 45% for women.

Neglected Water Nutrition

Many people think the content of mineral elements in water is very small and can be ignored. In fact, no matter how rich the diet structure, a certain proportion of important mineral elements required by the human body comes from drinking water.

According to an academician of the American Academy of Engineering, over the long-term, consumption of ion-free water can lead to nutritional deficiencies [2].

The World Health Organization's Nutrients in Drinking Water states that drinking water is an indispensable source of minerals intake for human body. Purified water cannot supplement minerals, and causes the loss of mineral elements from the body [3].

Why test the pH of water?

The pH of water is determined by the mineral components dissolved in the water. Natural water normally contains many minerals such as potassium, calcium, sodium, magnesium, metasilicate, etc., results in weakly alkaline of water. Water without minerals tends to be acidic. Therefore, by testing the pH of water, you can briefly determine if the water contains natural minerals.

Dringing Water Suitable for Infants And young children

What kind of water is suitable for infants and young children?

Chinese Nutrition Society recommends that infants and young children should scientifically drink water based on different growing stages [8].

0-6 months babies

0.7 L per day

unless the weather is hot or other reasons

breast milk can fulfill water requires

7-12 months babies

0.9 L per day

60% is supplemented by milk

40% through water and other complementary food supplements

1-3 years old

1.3 L per day

more than 60% from water

and complementary food supplements

Note:

Refer to Reference Intake of Dietary Nutrients for Chinese Residents

The mineral content of drinking water for infants and young children should not be too high

The liver and kidney functions of infants and young children are not yet mature. Drinking high mineral content water will increase the burden on the liver and kidney of infants and young children.

The German Federal Law Gazette [9] and the Austrian Federal Law Gazette [10] both explicitly require that the drinking water provided to infants and young children should have sodium ≤20mg / L.

In 2005, the journal from WHO, “Nutrients minerals in drinking water: implications for the nutrition of infants and young children” [11] pointed out that infants and young children are more vulnerable to the harmful effects of high mineral salt intake.

Bulgaria Pediatricians also recommend TDS ≤ 100 mg/L for infant drinking water [12]. TDS refers to the total dissolved solids in water.

Drinking water for infants and young children must not be completely free of mineral elements

Infants and young children have relatively narrow channels to obtain minerals, it is necessary for drinking water to contain suitable minerals. Long time purified water drinking will take out the body's own sodium, potassium, calcium, magnesium and other minerals. Infant formulas normally contain only 8 to 12 mineral elements. Baby's growth needs nutrition, so it is recommended to use drinking water containing natural mineral elements to brew milk powder.

Infant drinking water must strictly meet microbe limits

As the gastrointestinal tract of infants is still very fragile, foreign countries require commercial sterility of drinking water for infants [13], China also has strict microbiological requirements for liquid food for infants [14-16].

China stipulates that liquid infant formula must meet the requirements of commercial sterility, but infant drinking water is not included at present. There is no requirement for commercial sterility in the existing sanitary (safety) standards for drinking water and bottled drinking water, either.

Commercial sterility: the product contains no pathogenic microorganisms, or non-pathogenic microorganisms that can reproduce at normal temperatures.Therefore, even if the mineral content of ordinary bottled water meets the requirements, it still needs to be boiled before infants and children drinking.
