Uncle Wu is 55 years old this year, and he never leaves his teacup, and his mantra is: "The stronger the tea, the deeper the love." The family shook their heads when they saw it and persuaded him: "Dad, your tea is too strong, and it is not good for your health." ”
But he always waved his hand and smiled disappreciatively: "My body is hard-boned, what are you afraid of drinking a few cups of tea?"
However, Uncle Wu's body began to feel difficult to breathe often, loss of appetite, bad breath became worse and worse, and even urine was reduced.
One day, he suddenly passed out at home. The family rushed him to the hospital, and after a series of examinations, the doctor told them heavily: "Uncle's kidney failure is already very serious, and we need to be rescued immediately." ”
After several hours of rescue, Uncle Wu still couldn't survive. The doctor sighed and told his family: "If I had listened to the advice earlier and drank less strong tea, maybe I wouldn't have come to this point." ”
1. Who is healthier if you drink water or tea?
Plain water and tea have been competing for the top spot in the list of healthiest drinks, who is healthier?
Let's take a look at the benefits of drinking tea for the body.
First of all, drinking tea is good for cardiovascular health. A study published by Gu Dongfeng's team in the European Journal of Preventive Cardiology showed that the incidence of cardiovascular and cerebrovascular diseases decreased by about 20% and the overall mortality risk by about 15% in the regular tea drinking group compared with the non-tea drinking habit group.
Secondly, for middle-aged and elderly people, drinking tea in moderation can make the brain younger. Tea polyphenols act as a natural antioxidant that scavenges free radicals and reduces cell damage, thereby slowing down the aging process of the brain.
In addition, tea is rich in catechins, which can prevent the onset and progression of Alzheimer's disease by inhibiting the aggregation of β-amyloid.
There is also a correlation between tea drinking and diabetes prevention. A number of studies have shown that a variety of components in tea, such as tea polyphenols and catechins, have the effect of lowering blood sugar and improving insulin sensitivity, which is beneficial for the prevention of type 2 diabetes.
Seeing this, many people may think that tea has won the victory, but in fact, the benefits of plain water are not lost to tea.
As early as ancient times, there were medical classics that recorded the benefits of drinking water. The "Compendium of Materia Medica" mentions that drinking cold boiled water is beneficial to gastrointestinal contraction, which can not only promote metabolism, but also increase the content of hemoglobin in the blood.
Research from the University of Illinois at Urbana-Champaign also supports this idea: drinking more water can help the body consume more sugar, salt, cholesterol, etc.
According to research in the journal Clinical Nutrition, people who drank more plain water consumed more fiber, less sugar, and lower calorie-dense foods, suggesting that drinking water can help improve eating habits and have a positive impact on overall health.
In fact, whether you drink water or tea, it is a high-quality choice, and the key to drinking healthy is in moderation.
2. Tea is a good health product, and drinking too much will cause three major injuries
Everything needs to be moderate, and drinking tea should not be excessive, otherwise health products will also hurt the body.
Anemia
Drinking tea will inhibit the body's absorption of iron, which may lead to the occurrence of iron deficiency anemia in the long term. Patients with anemia may experience symptoms such as dizziness, fatigue, and even difficulty breathing in severe cases.
Insomnia
Tea contains caffeine, and excessive intake can cause the central nervous system to be in a state of constant excitement, affecting sleep quality. Patients with insomnia may have difficulty falling asleep or waking up frequently, and prolonged insomnia can affect their mental state and productivity during the day.
Osteoporosis
Excessive tea consumption will increase the content of oxalic acid in the body, which will combine with calcium in the body to form a water-insoluble calcium oxalate precipitate, which in turn will affect the body's absorption of calcium. Calcium deficiency may lead to muscle cramps, cramps and other symptoms, and in the long run, it can lead to a decrease in bone density and prone to fractures.
3. Healthy tea drinking is exquisite, and it can be done easily
Drinking tea should also pay attention to the way, learn to drink tea correctly, in order to taste health in the fragrance of tea, today I will share with you 4 tips for drinking tea.
Tea consumption: Moderate is healthier
Excessive tea consumption will lead to increased excitability of the central nervous system, causing insomnia, palpitations and other uncomfortable symptoms. Drinking tea in moderation can help relieve fatigue and improve sleep quality.
Drinking temperature: warm is preferred
Drinking hot tea can burn the mucous membrane of the mouth and esophagus, which is so easy to induce cancer in the long term. Warm tea is less irritating to the body and is conducive to retaining the nutrients of the tea.
Tea Drinking Options: No strong tea
Xu Qian, a nutritionist at Xiamen Haicang Hospital, mentioned that strong tea should not be drunk because it contains caffeine, theophylline and other ingredients, which will increase the excitability of the central nervous system, resulting in over-excitement of the brain, which can cause insomnia and other problems.
Strong tea also slows down the contraction of the stomach and the peristalsis of the intestines, affecting the digestion and absorption of food, leading to dry stools and constipation.
Fourth, the drinks that you really want to drink less are these 4 kinds
There are many favorite drinks to drink, but they are not so friendly to the body of the elderly. What are some drinks that older people should drink less?
First, beware of sugary drinks, they usually contain high amounts of sugar and calories, such as carbonated drinks, sweet teas and some fruit juice drinks, long-term consumption of large amounts may raise blood sugar levels, increase the risk of diabetes, and also easily lead to weight gain and dental problems.
Second, be cautious of caffeinated beverages. Caffeine has a refreshing effect, but excessive intake may lead to insomnia, heart palpitations, anxiety, and other problems, which is not good for sleep quality and heart health in the elderly.
The third is to drink less alcoholic beverages. Older people may have weakened liver function, a reduced ability to metabolize alcohol, and excessive alcohol consumption increases the risk of liver disease and other health problems.
Whether it is tea or water, the elderly should prioritize health and nutritional needs when choosing drinks, and pay attention to drinking in moderation.
