Expert: Drink green tea in the morning and medlar in the afternoon.
Green tea and Lycium barbarum can be brewed and drunk with boiling water respectively, which is very beneficial to human body. Many people simply put them together to brew. However, a large amount of tannic acid contained in green tea has convergence and adsorption effects, which will adsorb trace elements in Lycium barbarum and produce substances that are difficult for human body to absorb. There are both green tea and medlar in the popular eight-treasure tea in restaurants. Although the amount of green tea is small, it is not advisable to drink more.
Drink green tea in the morning
Green tea and medlar are very nutritious. Green tea contains catechins, β-carotene, vitamin C, vitamin E and so on. Many experiments have proved that green tea can scavenge free radicals, delay aging and prevent cancer.
Drinking green tea regularly can prevent cell gene mutation, inhibit the growth of malignant tumors, lower blood lipid and blood pressure, prevent cardiovascular diseases, prevent colds and dental caries, and eliminate bad breath.
Lycium barbarum is flat in nature and sweet in taste, and has the effects of tonifying kidney and essence, nourishing yin and blood, nourishing liver and improving eyesight, moistening lung and relieving cough. Many health care drugs contain Lycium barbarum. Lycium barbarum contains amino acids, alkaloids, betaine, acid pulp, vitamins and linoleic acid.
Suggestion: You can drink green tea in the morning to stimulate your appetite and refresh your mind. Drinking Lycium barbarum in the afternoon can enhance physical fitness and help sleep.
Drinking black tea in winter is most suitable.
Chinese medicine believes that the tea you drink in spring, summer, autumn and winter should be different. It is to drink suitable tea in different seasons according to the nature and taste of various teas.
Black tea can warm the stomach, wake up and help digestion. It is most suitable for drinking warm black tea in cold winter. Green tea tastes bitter and cold. Drinking in winter is easy to cause stomach cold and may also affect appetite. When summer is hot, drinking green tea can just take its bitter and cold nature, relieve summer heat and quench thirst.
Many people like to drink some tea after a big meal, which is not good for their health. A large amount of tannic acid in tea will combine with protein to produce tannic acid protein, which has astringent effect and weakens intestinal peristalsis, thus prolonging the retention time of food residues in the intestine and leading to dry stool. Therefore, it is best not to drink tea after a full meal.
Tea has two opposite effects.
Tea has both refreshing and nourishing effects. The refreshing function can make the brain awake and flexible, while the nourishing function can inhibit and soothe the nerves. What is the reason why the same tea can cause these two opposite effects?
Tea has just been soaked for about 3 minutes, and most of the caffeine in tea has dissolved into tea. At this time, tea has obvious refreshing effect and makes people excited. Later, tannic acid in tea gradually dissolved into tea, which counteracted the effect of caffeine and made people less likely to have obvious physiological excitement.
So the function of tea has two sides. Some people are afraid to drink tea at night for fear of falling asleep. In fact, as long as you pour out the tea that has just been brewed for about 3 minutes, and then continue to brew it with boiling water, the refreshing effect will not be so obvious.
Many people brew green tea and medlar together. However, a large amount of tannic acid contained in green tea has convergence and adsorption effects, which will adsorb trace elements in Lycium barbarum and produce substances that are difficult for human body to absorb.
When should women not drink green tea (Figure)
You can't drink tea every time, especially female friends, so as not to get worse! The periods when female friends are not suitable for drinking tea are divided into:
green tea
1. Every month when the physiological period comes. Because menstrual blood will consume a lot of iron in the body at this time, female friends should add more vegetables and fruits rich in iron, such as spinach, grapes and apples. However, if you are used to drinking tea when you are full, this kind of tea contains as much as 50% tannic acid, which will hinder the absorption of iron by our intestinal mucosa and greatly reduce the absorption of iron, so it is easy to precipitate iron in the intestine and chyme or iron stone in blood-enriching drugs.
2. It is not suitable for drinking tea during pregnancy. Generally, the concentration of caffeine contained in strong tea is as high as 10%, which will increase the times and frequency of urination and heartbeat of pregnant women, increase the load on their hearts and kidneys, and more easily lead to pregnancy poisoning, so it is better to drink less tea.
Pregnant women should not drink too much tea before giving birth. If you drink too much strong tea before giving birth, the caffeine in the tea will have an exciting effect and lead to insomnia. If pregnant women don't get enough sleep before delivery, it may lead to exhaustion and even dystocia during delivery. This is a big rule!
Mothers who want to breastfeed themselves just after giving birth should not drink too much tea. Because if you drink a lot of tea during this period, the high concentration of tannic acid in tea will be absorbed by mucosa, which will affect the blood circulation of breast and inhibit milk secretion, resulting in insufficient milk secretion.
After the mother drinks the tea, the caffeine in the tea will penetrate into the milk, indirectly affecting the baby, which is not good for the baby's health.
6. In addition to dizziness and fatigue, menopausal women sometimes have an accelerated heartbeat, so they have a bad temper and poor sleep quality. If they drink too much tea, these symptoms will get worse. Therefore, if people who like drinking tea are at these special stages, it is best to stop, so as not to ruin their health!
