In daily life should not drink water: 8 ( excerpt from " food and drug incompatibility with a full " )

In 1, the aging water

Aging of water, commonly known as "backwater ", is also the long time deposit and immobile water. Bottled water and bottled drinking water, is resting state stored for more than 3 days, will become the aging aging water ( water ). Chang He this water, on minors, will make the new supersedes the old. Cells was obviously decreased, effect of body growth and development: the old can accelerate aging; according to medical studies, esophageal cancer, gastric cancer incidence rate increased, probably related to long-term drinking water-related aging.

In 2, thousands of boiling water

Thousands of boiling water, is not after purification, containing impurities contaminants, boiling on the stove a night or very long time in the water, was also included in the electric kettle repeatedly boiled water. The water calcium, magnesium and other heavy metals and high nitrite content, affect gastrointestinal function, appear even coma, convulsions and other symptoms.

3, distilled water

Distilled water is the result of artificial pure water, including the OR reverse osmosis water, the purity of 99.9%, but the water mineral composition is not worth mentioning, pH value is less than 7 shows for the acid. The water is generally only used in medicine and industry, not suitable for long-term drinking.

4, raw water

Even if a water tap. Although meet the national drinking water standards, but in the process of conveying two pollution is unavoidable, it makes some tap water contains a variety of harmful bacteria, viruses and human zoonotic parasites drink after storage, easy to cause acute gastroenteritis, viral hepatitis, typhoid, dysentery and parasitic infection.

Drink without boiling water, the risk of bladder cancer, rectal cancer increases the likelihood of 21~38%; when the water temperature reaches 100 ℃, harmful substances will with the steam evaporation significantly reduced, if continue to boil for 3 minutes, it will be much safer drinking.

In 6, the water in the air for a long time

Boiling water with oxygen and other active substances, if the boiling water in the air exposed for too long, these substances will evaporate, the lack of oxygen in the active substance, boiling water solubility will become bad; at the same time, the water of the nitrite content of harmful substances such as increased relatively.

In 7, the overnight in water

Overnight water is served in warm bottle is not the boiling water, damage similar to air the water for a long time.

8, to boil water

A people accustomed to a hot water bottle in the residual temperature boiling water to boil, to drink, to save water and gas power saving. But this approach is not science. Because the water and boil the water, evaporation will rise again, nitrite, often drink this water, nitrite will accumulate in the body, causing poisoning.
