Under the propaganda of roadside advertisements, Aunt Wang from Beijing specially came to the store to buy alkaline water with "efficacy". Aunt Wang said that her uric acid was high. I heard that alkaline water can reduce uric acid and cure gout, and I am willing to give it a try.

In recent six months, Miss Li and her husband are actively preparing for pregnancy. They learned on the Internet that alkaline water is "small molecule pregnant water". At the recommendation of the merchant, she changed the water in her house to alkaline water.

Recently, CCTV exposed the "alkaline water scam", and a water supply company in Kunming claimed that alkaline water had a therapeutic effect and had been investigated.

Alkaline water generally refers to water with PH greater than 7. Because there is no fixed national standard, we can only judge from common sense.

There are a lot of alkaline water on the market that claims to have therapeutic and health-preserving effects. According to relevant personnel, alkaline water can metabolize acidic substances in human body and maintain the balance of pH. Long-term drinking can treat gout, hyperuricemia and reflux gastritis.

But in fact, alkaline water has no curative effect and cannot replace drugs.

Experts say that although alkaline water contains sodium bicarbonate, its content is very small. Drinking it can only replenish water and cannot adjust physical fitness. Professor Zhu Wenli from the Department of Nutrition and Food Hygiene of Peking University College of Public Health believes that chronic diseases can be prevented as long as you drink enough water, and you don't have to worry about the pH value of water.

Alkaline water has no special function. If enterprises mislead consumers in order to obtain profits, they will violate relevant laws and regulations, such as the Consumer Protection Law and the Advertising Law, and need to be held accountable.

With the accelerated pace of life, more and more people like to drink convenient and fast bottled water. But many people don't know that while you drink bottled water, microplastics is also invading your body.

On March 24th, a research team led by the Free University of Amsterdam in the Netherlands discovered microplastics in human blood for the first time. After the researchers ruled out the possibility of blood sample contamination, a quantifiable microplastics was found in 17 blood samples of 22 healthy volunteers, of which 50% was polyethylene terephthalate, 36% was polystyrene and 23% was polyethylene.

It has long been an indisputable fact that microplastics will do harm to health.

202165438+February, Environmental Science &; A study published by Technology Letters found that microplastics particles in feces of patients with inflammatory bowel disease were 1.5 times more than those of healthy people. The more patients with inflammatory bowel disease have microplastics, the more obvious the symptoms such as diarrhea, abdominal pain and rectal bleeding.

The researchers also found that people who often drink bottled water, use take-away plastic products and live or work in dusty environment for a long time have more microplastics in their feces.

In this way, everyone has microplastics to some extent. What's the difference between drinking bottled water or not?

According to the data of environmental science and technology, the human body may consume as many as 39,000 ~ 52,000 microplastics tablets every year, while people who drink bottled water often consume 2 1. 1.00 million microplastics tablets.

It is best to choose boiled water for drinking water. In addition, "drinking water" is equally important.

Generally speaking, due to physiological activities such as excretion, respiration and skin evaporation, the human body excretes 2500ml of water every day and takes in 1000ml of water from the diet every day. Therefore, the human body needs to supplement about 1500~ 1700ml of drinking water every day to balance the intake and discharge of water and meet the needs of physiological activities.

When the human body is short of water, the body will send out a signal of thirst, but the generation of thirst is relatively lagging behind. In order to avoid the impact of water shortage on health, it is best to form the habit of drinking water regularly. We can drink a glass of water after getting up, 30~ 120 minutes before or after meals, and one hour before going to bed.

In addition, if intensive activities are carried out, the amount of drinking water should be increased appropriately.

Many people don't care about the phrase "drink more water", but do you know that drinking more water and drinking less water are physiologically different?

Compared with people who don't drink water often, people who drink more water will obviously improve their bladder, kidneys, blood, intestines, uric acid and weight.

Drinking more water can increase the frequency of urination, reduce the growth of urinary tract bacteria, reduce the risk of kidney calculi, reduce blood viscosity and reduce the probability of thrombosis. It can also make defecation smoother, discharge excess uric acid in the body, and reduce the chance of gout. It is more conducive to the smooth metabolism of fat, helps to lose weight, helps the body to dissipate heat, and relieves the symptoms of fever and cold.

Water accounts for 60%~70% of human body weight and plays an important role. We should drink more water in our daily life, especially for the elderly.

A study by the University of Ottawa in Canada in 2020 believed that the older you get, the more you need to drink water to make up for the changes in thermoregulation. The older you get, the less active the hypothalamus signals "thirst", so you should drink water regularly, not just by feeling.

Water is the source of life. We should drink more water and drink water correctly in order to have a healthy life.
