Drinking two hours after a meal is the same as eating fruit. Because fruit is easier to digest than other foods, in order not to interfere with the digestion of dinner food in the stomach, it is more appropriate to drink it 2 hours after meals. In addition, avoid drinking before going to bed at night, because drinking water at night will increase the burden on the kidneys and make the body edema easily. Better drink slowly. Drink fresh fruit and vegetable juice, not heroic. Drink it in a tasting mood, so that it can be easily absorbed completely in the body. If you drink heavily, the sugar in the fruit and vegetable juice will quickly enter the blood, which will make the blood sugar rise rapidly. Some people like to add sugar to improve the taste of fruit and vegetable juice, but the decomposition of sugar will increase the loss of vitamin B group and calcium and magnesium, and reduce nutrition. If the fruit and vegetable juice tastes bad, you can use sweet fruits such as cantaloupe and pineapple as a match, or add honey appropriately to increase the intake of vitamin B6.
