You can drink. Some people think that excessive nitrite will cause cancer if water is boiled repeatedly. In fact, although water does produce some nitrite after several times of heating, laboratory data show that the nitrite content of tap water is still far below the standard of good drinking water after several times of boiling. Don't worry about "nitrogen poisoning" and "carcinogenesis".
2. Does too much water increase the burden on the kidneys?
On the contrary, as long as the renal function and cardiac function are normal, encourage drinking more water. Drinking water is to replenish water. Everyone's physical needs and amount of exercise are different. You can drink 1.5 to 2 liters of water every day according to your own situation, and the urine color is bright yellow. Drinking more water can improve constipation, reduce uric acid, and the climate in winter is dry. Water can also moisten the mouth and throat.
3. Should the leftover food be cooled and put in the refrigerator?
Compared with "putting hot dishes directly in the refrigerator", when the temperature drops to the same temperature, bacteria will produce more bacteria in food. If it is stored in the refrigerator for a short time, the increased bacteria are still within the acceptable range. However, it is recommended to wrap the food directly in the refrigerator with plastic wrap, and don't wait until it is cold. This will increase the number of bacteria, but it will only increase the motivation.
4. Can plastic packaging be heated?
There are several types of plastic wrap, some of which can only be used to package foods at low or normal temperature, and some of which have better performance and can withstand the high temperature of microwave heating. Please check the "Temperature Tolerance" and "Scope of Application" on the package. As long as the plastic package is marked with "microwave heating", please feel free to use it.
5. Can't you eat eggs when you have a fever?
You can eat. It is rumored that eggs with high protein content will increase the body's heat when they have a fever, which is not conducive to the recovery of the disease. At present, there is no research to prove this statement. After eating, different foods will bring different calories to the body. But the extra calories from eating one or two eggs have little effect on body temperature.
6. Can red wine soften the cardiovascular system?
You can't. Many people think it can soften blood vessels, because red wine contains resveratrol and other ingredients. In fact, the content of resveratrol in red wine is not high, and drinking a little every day has no effect on oxidation and arteriosclerosis. The alcohol content of 12% to 15% in red wine can not be ignored. Many authorities, including the World Health Organization (WHO), explicitly oppose the use of alcohol to protect blood vessels or the heart.
