What kind of water to drink is definitely a topic with many opinions.
(1)Boiled water is the best water
Simple is best. Boiled water is the best water, economical and practical, safe and hygienic, and has a good hydrating effect. Of course, the quality of boiled water in different regions depends on the quality of local tap water, which in turn depends on the quality of the water source. The state has detailed and clear requirements for the quality of drinking water. At least in theory, qualified tap water is trustworthy. It is worth noting that if you see scale when boiling water, it does not mean that the water quality is poor, but it only means that the hardness of the water is high, that is, the content of calcium and magnesium is high, and both calcium and magnesium are beneficial to the human body.
Pure water, mineral water and mineral water are similar to boiled water, as long as they are hygienic and qualified products, they can be used. The actual impact of minerals on health is minimal, and pH and pH are not critical. In the final analysis, drinking water is to replenish water safely and conveniently. As for the words “pure”, “mineral spring” and “mineral”, they are just marketing selling points or differences in taste, and have nothing to do with the overall health situation. The large bucket of water on the water dispenser for home or office should be refreshed as soon as possible, as it may cause bacteria to grow if it is left for too long.
There are many “alkaline water”, “oxygen-enriched water”, “glacier water”, “magnetized water” and “reduced water” on the market Aquatic products such as “small molecular mass water”, “active water” and “electrolyzed water”, every kind of aquatic product is advertised to bring great health benefits, and some even openly claim to treat high blood pressure, diabetes and other diseases. But their health benefits have never been proven by serious academic research, and are mostly just concepts or speculation. From a market perspective, they should probably be considered a “luxury” for drinking water for those willing to spend.
Household water purification equipment has merits, but whether it must be installed, is it worth installing, and what is the cost-effectiveness? These value judgments need to be considered by consumers There is no unified answer for the situation in itself and the environment.
(2) Lemonade rumors outweigh actual results
Lemonade is growing in popularity and rumors abound. Although light and unsweetened lemonade is a healthy drink, it is groundless to say that it can prevent many types of cancer, which is comparable to rumors. There are many similar rumors, such as stomach disease can not drink lemonade; lemonade can promote the formation of kidney stones, or bring acidic constitution; high blood pressure, high blood fat, high blood sugar patients can not drink lemonade; can not drink lemonade during the day and so on. These claims are completely unsustainable and have no evidence.
Lemon soaked water must be light, with a little sour and bitter taste, and can be drunk without sugar or honey. Lemons should be peeled and cut into thin slices to fully dissolve beneficial ingredients such as citric acid, flavonoids, and essential oils. The water should not be too cold, warm water is the best, to promote the dissolution of beneficial substances. Hot water can also be used, it will be more acidic, so it is best to drink it after cooling. Do not boil, otherwise vitamin C will be destroyed and the taste will be poor. You can use 1 slice of lemon soaked in water at a time, and wrap the rest in plastic wrap and put it in the refrigerator. There will be no problem in a few days.
(3) Drinks are the worst way to hydrate< /p>
Sweet beverages generally contain a lot of sugar, pigments, preservatives, salt, etc., which not only have poor hydration effect, but also may not quench thirst if you drink a lot, and frequent drinking is not good for your health. Dietary Guidelines recommend not substituting beverages for water.
In addition to sugar, beverages are generally high in sodium (the equivalent of salt). Adding salt to beverages can accentuate sweetness, improve flavor, enhance taste, preservatives, and more. This is also the reason why drinking beverages is less effective in quenching thirst.
The World Health Organization (WHO) recommends that the daily intake of sugar should not exceed 25 grams. Almost any bottle or can of sugar-sweetened beverages contains more than 25 grams of sugar. If you must drink beverages, it is recommended to choose sugar-free beverages.
(4) Both real tea and fake tea can be hydrating

Drinking pure white water when not thirsty makes many people feel dull. At this time, drinking light tea with tea fragrance and different flavors is undoubtedly the most recommended way to replenish water. Green tea, red benzene, white tea, scented tea, oolong tea, Pu’er tea, etc. are all natural and healthy drinks with no sugar, no fat, no salt, and no additives. They are very effective in quenching thirst and hydrating.
More importantly,tea water contains tea polyphenols, also known as tea tannins or tea sucrose, which have Strong antioxidant effect, beneficial to blood lipids, blood pressure and cardiovascular health. However, tea polyphenols can stimulate gastric acid secretion, so it is not recommended for patients with peptic ulcer or chronic gastritis to drink more tea (except for atrophic gastritis), especially strong tea.
Rose, jasmine, chrysanthemum, osmanthus, snow chrysanthemum and other flowers are suitable for soaking in water “Tea”, they are not really tea, they are free of polyphenols and caffeine. Sometimes a little bit of sucrose, rock sugar or honey will not affect their health as a drink.
Barley tea, Mangmai tea, and brown rice tea are not real tea, but brewed with roasted seeds. Water, fragrant, can provide some nutrients, does not contain tea polyphenols and caffeine, suitable for drinking before meals, and drinking at night does not affect sleep. But iced black tea beverages, tea polyphenol beverages, grapefruit tea beverages, scented tea beverages, milk tea and other sweetened beverages only have the name of tea and are not recommended for health without the reality of tea]
(5) Food also hydrates
Liquid food is one of the important sources of water.Soup, porridge, milk, soy milk and other liquid food can replenish water. Fruits also contain a lot of water.
Vegetable-based clear soups,such as cucumber soup, loofah soup, spinach soup, winter melon soup, Radish soup, mushroom soup, mushroom soup, etc. can be used to replenish water. Lycium barbarum soaked in water, mung bean soup, papaya and Sydney soup, lotus seed and white fungus soup, red dates drink, etc., can also replenish water, but usually add sugar and only drink less.
rice porridge and rice soup,such as millet porridge, polenta, rice porridge, multigrain porridge, mung bean porridge, black rice Porridge, oatmeal, etc. can also be hydrating, except sweetened or too viscous.
The water content of liquid milk is close to 90%, and the water content of yogurt is about 85%, so drinking milk is also an effective way to replenish water. The proportion of water in soy milk is higher than that of milk, and it is also suitable for hydration by the way, which has both thirst-quenching and hunger-quenching effects.
Watermelon, citrus, apples, pears and other fruits are excellent for hydration because their water content is close to 90% With the combination of organic acids, the taste is refreshing, especially thirst-quenching.
