But 2000ml of water is not necessarily obtained by drinking water, and the moisture in food should be included.
In fact, the food we eat every day contains a lot of water. For example, most vegetables and fruits contain more than 90% water, while eggs and fish also contain about 75% water. It is roughly estimated that we can get at least 300 ~ 400 ml of water from food or soup when we eat a meal.
Therefore, after deducting 1 0,000 ~ 1 0,200ml of water for three meals, we only need to drink10,000 ~10,200ml of boiled water every day, with an average of 2 cups in the morning and 2 cups in the afternoon, and it is ready.
However, the demand for water must depend on everyone's environment (temperature, humidity), exercise, health and food intake. There is no standard value.
Not less than 500 ml per day, but not more than 3000 ml.
However, some people do need to drink more water, including gout and kidney calculi's patients. The insurance method is to follow the doctor's advice.
It is no problem for normal people to drink about eight glasses of water every day ~
