As we all know, drinking tea is a very healthy project, and the tea culture that has been passed down in the mainland for a long time has always shined even in modern health research.
For example, the journal "European Epidemiology" has mentioned that proper tea drinking can effectively reduce the risk of cancer; For example, the American Heart Journal has followed up more than 80,000 Chinese tea friends and found that the risk of cardiovascular disease and high blood lipids has decreased significantly in people who drink tea regularly. However, although drinking tea is good, it is not "the stronger the better", often drink strong tea, but the body will taste the "bitter fruit".
Uncle Lin, 51 years old, was lying on a bed at the Fourth People's Hospital of Guangxi Medical University, and according to the doctor's description, Uncle Lin was suffering from two diseases. One is severe osteoporosis complicated by mild anemia; The other is acute kidney stones. The reason for Uncle Lin's "miserable situation" is also related to drinking strong tea.
Thunder can't move! The uncle drank strong tea every day for 5 years, but finally ate the "lesson" with tears
Uncle Lin's habit of loving tea can be said to be famous in the neighborhood. Every afternoon, he would hold a thermos cup filled with liquids that were either green or brown, and wander around the square while drinking. Even on rainy days, Uncle Lin likes to sit on the balcony, sipping tea while enjoying the rain.
This is beyond reproach, middle-aged people like to drink tea, is a good habit of health and wellness. But the mistake is that Uncle Lin's "mouth weight", only has a special love for strong tea, there are good people who once asked Uncle Lin's tea cup to taste a sip, almost suffered a mouthful of tea squirted out.... It is enough to see the degree of Uncle Lin's obsession with strong tea.
But because of this, the disease immediately found him, one day, Uncle Lin was tasting a jar of fragrant Pu'er, suddenly felt a sharp pain in the waist, and even the pain was dripping cold sweat, Uncle Lin's daughter saw the situation, quickly took her father to the hospital for examination, and the final result must have been seen at the beginning: Uncle Lin was an acute kidney stone accompanied by nephritis, and the doctor also found that Uncle Lin had severe osteoporosis symptoms, which was really lamentable.
Just because the concentration of tea is a little higher, it actually causes osteoporosis, as well as kidney stones, two serious diseases, why is this? Many friends still have doubts in their hearts.
The harm of strong tea is more terrible than imagined! How exactly do osteoporosis and kidney stones occur?
Regarding these 2 symptoms, we may wish to say one by one:
The first is osteoporosis:
An important cause of osteoporosis is the loss of calcium inside the body, less calcium absorption in bones, less bone, and the inside of the bones will slowly become "sparse", become "empty", and finally form the hidden danger of osteoporosis.
The substance oxalic acid in tea leaves, if drunk in small amounts, may not cause significant health effects. However, if you drink strong tea every day, excessive oxalic acid and calcium in the body are combined in advance, and the amount of calcium absorption is not good at its own age, which is more lacking in calcium, and osteoporosis will develop faster.
Shanxi Provincial Hospital of Traditional Chinese Medicine once conducted etiological analysis on 1200 cases of clinical osteoporosis patients, "often drinking strong tea", ranking fourth in the etiological population, which shows its threat to bone health.
This is followed by kidney stones:
The two are linked, tea in the catechin, oxalic acid and other substances, after combining with calcium will form a precipitate, excess precipitation continues to operate and accumulate in the metabolic system, it will form stones, kidney stones hidden dangers and risks will also increase.
Therefore, no matter what you do, the most important thing is to stop at the right time, drinking tea properly is beneficial, excessive drinking of strong tea is harmful, and I hope to remember.
Not only that, but drinking strong tea also brings some other health risks.
Friends who often drink strong tea should pay attention to the risk of these 3 diseases can not be ignored
Anemia: often drink strong tea, catechins, oxalic acid, and most of the nutrients in the body can be combined, which may be synthesized with iron ions, forming a refractory precipitation, thereby reducing the level of iron ions in the human body in disguise, and the risk of iron deficiency anemia will also increase.
Tea poisoning. Yes, you read it right, tea drinking too much, there is also a risk of poisoning, some tea leaves have a higher fluoride content, long-term drinking of this type of tea, may lead to the body fluorosis. Specific manifestations are dizziness, nausea, abdominal pain and other symptoms, serious and even damage to the liver and kidneys, causing acute hepatitis or acute nephritis and other dangerous diseases.
Gastrointestinal ulcers. Too strong tea leaves, which caffeine, theophylline and other substances content is also a lot, long-term drinking of strong tea, these substances on the stomach is also a very obvious irritation, increase the hidden danger of ulcers in the stomach and intestines.
Not only that, long-term drinking of strong tea will also lead to existing ulcers that are difficult to heal, and even have the hidden danger of turning into chronic gastroenteritis, and even gastrointestinal cancer.
All of the above, all represent the hidden dangers that drinking strong tea will bring to the health, like drinking tea is a good thing, control the amount is the premise of health, what kind of tea is considered "strong tea"? There must also be standards.
What kind of tea is considered "strong tea"?
According to Professor Wang Yuefei, director of the Tea Research Institute of Zhejiang University, there is actually no clear definition of strong tea, but the bitterness and color of tea are usually linked to the concentration of strong tea.
In other words, the more bitter the taste, the more intense the color of the tea, which is what we call strong tea, if you drink it, it is obvious that there are these two characteristics, or put less tea leaves, and drink less is better, so as not to affect the health of the body. In general, the ratio of tea to tea is 1:25, which is relatively appropriate.
Even so, although the tea is healthy, it cannot be drunk every day without restriction, and according to the "Dietary Guidelines for Chinese Residents", it is healthier to drink tea within 6g per day. For example, pregnant women, children, or friends with serious insomnia symptoms, try not to drink tea, so as not to bring additional burdens to physical health.
In summary, although tea is good, but like wine, do not "greedy cup", do not drink too strong tea, so as not to bring serious hidden dangers to the body. Any healthy thing, moderate, is the healthiest choice.
