Xiaomei wondered, which one is healthier?
Drink mineral water
Water in nature is usually composed of carbonate of calcium and magnesium. Although the density of calcium is not high, it is a sustainable way to supplement calcium for human body because it is drunk every day and the amount of drinking water is large (adult drinking water is 1500-2000ml/ day).
However, it should be emphasized that water is not the main source of minerals, so there is no need to deliberately pursue mineral water. Water is water, its main function is to replenish water.
Drink boiling water
Dr. Zhang Mei from Beijing Physical and Chemical Analysis and Testing Center has previously studied the mineral content in water (including calcium, potassium, magnesium, sodium and strontium), and finally found that the mineral content in pure water is the lowest, and both mineral water and boiled water are half a catty.
Jia Kai, director of the Nutrition Department of Chaoyang Hospital affiliated to Capital Medical University, reminded that there is not much difference in mineral content between mineral water and boiled tap water. Therefore, for ordinary people, the best water source is boiled water.
Boiled water is especially suitable for diabetics. For example, sugar friends generally have poor gastrointestinal function, and some hypoglycemic drugs can stimulate the stomach, while other drinks such as tea will increase the stimulation of gastric mucosa and aggravate the stomach discomfort of patients. In addition, cataract patients need to drink plenty of boiled water, otherwise once dehydrated, some abnormal chemicals may be produced, which may damage the lens and aggravate the condition. People with poor kidneys should also drink plenty of boiled water, which can promote the excretion of metabolites or toxins in the body.
tea
Tea can play a certain health care role for human body, which mainly depends on its rich tea polyphenols. Tea polyphenols have certain antioxidant and detoxification effects, which can remove excess free radicals in the body and improve the immunity of the body.
For example, green tea is mainly composed of polyphenols-catechins. According to the reference intake of dietary nutrients for China residents (20 13), it is suggested that catechin can play an antioxidant role (250mg/ day) and reduce the risk of cardiovascular diseases such as blood sugar, blood pressure and blood lipid (400mg/ day).
It should be reminded that tea also contains caffeine. In a cup of green tea containing 2g tea, the caffeine is about 20mg. Therefore, moderate drinking of tea (3 cups/day) and coffee (2-4 cups/day) will not pose any threat to health.
In addition, ginger tea is also a good choice. Among them, gingerol can stimulate the enzyme decomposition in the mouth and get rid of bad breath, that is, bad breath.
In fact, each kind of water has its own advantages, but as a daily intake of water, boiled water may be more suitable.
Drinking enough water is of great significance to health, but the premise is to drink it correctly. Of the following three ways of drinking, which is the most like you?
The first way to drink: don't drink if you are not thirsty.
A lot of people do. They should drink water when they feel thirsty. Professor Ma Guansheng, director of the Department of Nutrition and Food Hygiene of Peking University School of Public Health, said that when you feel thirsty, your body is short of water. When the water loss reaches 2%~4%, the human body is thirsty and the urine is dark yellow, which affects the work and cognitive ability.
When you reach a state of moderate dehydration, you will feel very thirsty, dry skin, hoarse voice and even general weakness. Water shortage of more than 20% may lead to death. So I suggest you drink water on time, and don't wait until you are thirsty to remember to drink water.
The second way to drink: drink it all at once.
Pouring water in one breath will not only increase the gastrointestinal load, but also increase the risk of "water poisoning" (hyponatremia), causing symptoms such as nausea, vomiting, convulsions and disturbance of consciousness, so everyone should pay attention to avoiding this dangerous way of drinking water.
It is suggested that you reasonably allocate the total amount of water you need to drink every day at various times of the day, about 200ml at a time.
The third way to drink: I don't know how to adjust it.
Generally speaking, a healthy adult's daily hydration amount is about 2000ml, so you can allocate it reasonably at different times of the day according to the amount of about 200ml at a time, but you should learn to adjust flexibly for some special circumstances.
Huang Xiaoli, deputy director of the Nutrition Department of Qilu Hospital of Shandong University, suggested that after strenuous exercise, you should pay attention to drinking a small amount of water many times. After two or three sips, you should stop drinking later. When the weather is dry, the food is too salty, and you have a cold and fever, you need to replenish water.
In short, drink water automatically and consciously, not when you are thirsty. Pay attention to control the speed when drinking, don't worry, and adjust flexibly.
Besides drinking water, how to drink tea is also a university question. Drink tea healthily. Remember these points.
A study involving 50,000 people was published in the International Journal of Cancer, which once again showed that eating foods with too high a temperature, including scalded tea (60), can irritate the esophageal mucosa, causing it to be damaged, leading to edema or congestion. If this happens for a long time, morphological changes or hyperplasia may occur, which may increase the risk of esophageal cancer by 465,438+0%.
This tea contains a lot of caffeine. If you drink too much, it will stimulate sympathetic nerves and increase the chances of discomfort such as rapid heartbeat, palpitation, chest tightness and shortness of breath. Moreover, theophylline can excite the cerebral cortex and make people fidgety and insomnia, so people with poor sleep should not drink tea after 4 pm.
Drinking a lot of tea on an empty stomach will stimulate gastric acid secretion and easily damage gastric mucosa, so it is best to avoid this tea drinking mode as much as possible, especially for people with chronic gastritis, gastroesophageal reflux and other diseases.
If you drink tea at the same time and come into contact with these two "bad things", you will increase the risk of esophageal cancer.
In the process of tea processing, it may be polluted by harmful substances such as pesticides, and "head tea" has a certain washing effect, so it is best to throw it away.
Summary: Some people like drinking water, others like drinking tea, no problem. However, some people still feel thirsty after drinking tea. It is suggested that a little water can be added on the basis of drinking tea. At the same time, the amount of drinking water also needs to be controlled. Too much or too little is not good. Which do you prefer, tea, mineral water or boiled water?
