Drinking water also has different grades_Tibetan Health Knowledge Hall_Baidu Space

Water regulates the normal circulation of blood and tissue fluid, dissolves nutrients for energy supply, dissipates heat, regulates body temperature, and increases endurance. For people today, drinking water is no longer as simple as just replenishing fluids. The variety of drinks give us the opportunity to choose our favorite flavors and absorb corresponding nutrition. However, along with this comes the concerns of nutritionists. Experts have had to link the "water" that people drink daily with obesity, a disease spreading globally. For this reason, I would like to introduce to everyone the levels of healthy drinking.

Level 1: Water. Whether it be boiled water or mineral water, they are the basic substances for maintaining normal metabolism and physiological functions, and some essential minerals in the human body can be absorbed through drinking water.

Level 2: Unsweetened tea and coffee. Tea and pure coffee contain no calories. Tea contains abundant flavonoids which not only have antioxidant effects but also improve vascular dilation function. Drinking a moderate amount of coffee (no more than one cup per day) can reduce the incidence of type 2 diabetes.

Level 3: Low-fat, skimmed milk (or unsweetened soy drinks). Milk is an important source of calcium, magnesium, potassium, and vitamin D. There is substantial evidence indicating that drinking more milk helps improve bone density.

Level 4: Refers to tea beverages, milk beverages, etc. Evidence shows that the increase in beverage sweetness reduces the likelihood of people choosing low-sweetness foods.

Level 5: Refers to 100% fruit juice and vegetable juice, alcohol, sports drinks. These can be consumed in moderation when necessary, but they are not daily necessities.

Level 6: Refers to carbonated beverages such as cola, and fruit-flavored drinks with very little fruit juice content but high sugar content. These are more likely to cause obesity and should be consumed sparingly.

With this six-level pyramid, generally speaking, the proportion of zero-calorie beverages in daily consumption should exceed 60%; nutrient-rich beverages such as milk must not be replaced by low-nutrient, high-calorie beverages; the intake of sugary beverages must be reduced, while the intake of low-calorie beverages should be increased.
