为什么喝茶宜淡不宜浓?

开门七件事,柴米油盐酱醋茶,茶叶已经成为人们生活中不可或缺的饮品。

茶叶有浓有淡,有的老茶客喜欢喝有茶味的茶,往往将茶泡的过于浓厚,才感觉过瘾,刺激!对一些柔和的茶,总觉得不够味!

这样真的好吗?下面就来说说,浓茶和淡茶,哪个更养人?

淡茶养生胜过浓茶

茶,作为天然饮料备受世人的青睐。茶不仅含具有抗癌功效的茶多酚,还含有少量可以提神醒脑的咖啡因。此外,它又含有可以分解油腻、帮助消化的微量元素。

如果从健身养生的角度来看,那当然是饮淡茶好。我国民间广泛流传的《饮茶诀》中说:“淡茶温饮最养人”,“喝茶过浓犯茶瘾”,强调的也正是这个道理。

为什么不宜喝浓茶?

1浓茶易伤胃

浓茶内的茶碱含量相对较高,会刺激胃壁细胞,导致胃酸过多,长期饮用浓茶,容易造成胃酸分泌过多,从而对患有胃溃疡、十二指肠溃疡的患者,造成极为不利的后果。

据统计,有10%的嗜茶者,在每天喝2-3杯浓茶的情况下,会出现神经过敏、焦虑不安和气短等现象。茶里的咖啡因具有使人上瘾的弊端,能促使人越喝越浓,从而会损害人的健康。

淡茶内的茶碱含量比浓茶少,足以使人提神醒脑、恢复体力,但又不会使人过度兴奋。

2浓茶阻碍营养吸收

浓茶中所含鞣酸也多,会阻碍人体对铁的吸收,表现为缺铁性贫血,还可以和食物中的蛋白质、维生素B1结合,导致便秘。营养专家发现过量饮茶会增加尿量,引起镁、钾等重要营养的流失。

3浓茶毁睡眠

茶叶中含有2%~5%的咖啡因,浓茶中咖啡因含量则更高。一杯浓茶中含有100毫克左右的咖啡因,所以喝茶,特别是浓茶,会使人兴奋少眠。

那为什么有些人喝茶之后不会有明显的少眠现象么?因为每个人对于咖啡碱的耐受力和代谢能力不同。对于咖啡碱耐受力强的人,咖啡碱所能起到的兴奋效果低,自然容易入眠。

4浓茶伤血管

过量的咖啡因除了会影响睡眠,还会引起大脑兴奋、不安、失眠、心悸等不适,从而使血压上升。

饮用浓茶,会增加血容量,在一定程度上还会加重心脏负担和心力衰竭症状。这些对心脑血管病人来说,有时候非常致命的。

这4种情况下不宜喝浓茶

⒈ 经期

经期因失血多,喝浓茶不利于铁的吸收,易导致贫血。还可因咖啡因的刺激引起痛经和延长经期。

⒉ 孕期

孕妇喝浓茶,不仅易患贫血,而且不利于其它营养素的吸收。浓茶中的咖啡因不仅影响胎儿的营养吸收,还会增加胎动次数,使胎儿发育不良,对母体和胎儿健康都不利。

⒊ 哺乳期

哺乳期喝浓茶,咖啡因可通过乳汁刺激婴儿引起兴奋作用,使婴儿不安,影响孩子生长发育。另外,鞣酸可抑制乳腺泌乳,影响哺乳。

⒋ 服药期

服药期间不可以喝茶水。因为茶叶中所含的鞣酸很容易与胃中的生物碱发生作用形成不溶的沉淀,从而使药不能被人体吸收,发挥不了药效作用。

除了以上情况下不适合喝浓茶,老年人也要少喝浓茶。因为老年人的身体各项功能本会随年龄增长逐渐减退。而茶叶却富含咖啡因,经常饮用浓茶,会使人心跳加快、出现心慌、心悸、胸闷、头晕等症状。

另外,其他的茶友们也要根据自身体质喝茶。

虽说饮茶,有人喜浓,有人喜淡,但从科学角度来说,还是建议大家尽量饮用淡茶,更有利于身体健康。

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.
