Why should tea be light but not thick?
Seven things to open the door, firewood, rice, oil, salt, sauce, vinegar, tea, and tea have become indispensable drinks in people's lives.
The tea leaves are rich and light, and some old tea lovers like to drink tea with a tea flavor, and often make the tea too thick, so that it feels enjoyable and exciting! For some soft teas, I don’t think it tastes enough!
Is this really good? Let's talk about it below, which one is more nutritious, strong tea or weak tea?
Light tea is better than strong tea
Tea, as a natural beverage, is favored by the world. Tea not only contains tea polyphenols, which have anti-cancer effects, but also contains a small amount of caffeine that can refresh the mind. In addition, it contains trace elements that can break down greasy and help digestion.
If you look at it from the point of view of fitness and health preservation, of course it is better to drink light tea. The "Tea Drinking Secrets" widely circulated in our country said: "Light tea and warm drinking are the most nourishing", "Drinking tea is too addictive to tea", which emphasizes this truth.
Why not drink strong tea?
1 strong tea is easy to hurt the stomach
The content of theophylline in strong tea is relatively high, which can stimulate the parietal cells of the stomach and cause hyperacidity. Long-term drinking of strong tea can easily cause excessive gastric acid secretion, which can cause serious problems for patients with gastric ulcer and duodenal ulcer. Adverse consequences.
According to statistics, 10% of tea addicts will experience nervousness, anxiety and shortness of breath when drinking 2-3 cups of strong tea a day. The caffeine in tea has the disadvantage of being addictive. It can encourage people to drink more and more, which will damage people's health.
The content of theophylline in weak tea is less than that in strong tea, which is enough to refresh one's mind and restore physical strength, but it will not make people over-excited.
2 strong tea hinders nutrient absorption
Strong tea also contains a lot of tannic acid, which will hinder the body's absorption of iron, which is manifested as iron deficiency anemia. It can also be combined with food protein and vitamin B1, leading to constipation. Nutrition experts have found that excessive tea drinking will increase urine output and cause the loss of important nutrients such as magnesium and potassium.
3 strong tea ruins sleep
Tea contains 2% to 5% caffeine, and the caffeine content in strong tea is even higher. A cup of strong tea contains about 100 mg of caffeine, so drinking tea, especially strong tea, will make people excited and sleep less.
Then why do some people have no obvious sleep loss after drinking tea? Because everyone has different tolerance and metabolic capacity for caffeine. For people with strong caffeine tolerance, the excitement effect of caffeine is low, and it is easy to fall asleep naturally.
4 strong tea damages blood vessels
Excessive caffeine will not only affect sleep, but also cause brain excitement, restlessness, insomnia, heart palpitations and other discomforts, which will increase blood pressure.
Drinking strong tea will increase blood volume, and to a certain extent, it will increase the burden on the heart and the symptoms of heart failure. These are sometimes very fatal to patients with cardiovascular and cerebrovascular diseases.
It is not advisable to drink strong tea in these 4 situations
⒈ Menstrual period
Due to heavy blood loss during menstruation, drinking strong tea is not conducive to the absorption of iron and can easily lead to anemia. It can also cause dysmenorrhea and prolong menstruation due to the stimulation of caffeine.
⒉ During pregnancy
Pregnant women who drink strong tea are not only susceptible to anemia, but also are not conducive to the absorption of other nutrients. The caffeine in strong tea not only affects the nutrition absorption of the fetus, but also increases the frequency of fetal movement, which makes the fetus underdeveloped, which is detrimental to the health of the mother and fetus.
⒊ Lactation period
Drinking strong tea during lactation, caffeine can stimulate the baby through breast milk to cause excitement, make the baby restless, and affect the growth and development of the baby. In addition, tannic acid can inhibit breast lactation and affect lactation.
⒋ Medication period
Do not drink tea while taking the medicine. This is because the tannic acid contained in tea can easily interact with the alkaloids in the stomach to form insoluble precipitates, so that the medicine cannot be absorbed by the human body and cannot exert its efficacy.
In addition to the above conditions, it is not suitable to drink strong tea, the elderly should also drink less strong tea. Because the various functions of the body of the elderly will gradually decrease with age. The tea is rich in caffeine. Drinking strong tea regularly can make people’s heartbeat faster, palpitation, palpitations, chest tightness, dizziness and other symptoms.
In addition, other tea lovers should drink tea according to their physical constitution.
Although some people like to drink tea, some people like it, but from a scientific point of view, it is recommended that you drink light tea as much as possible, which is more conducive to your health.
