饭后立即饮茶 等于喝毒药？1Tea immediately after meals to drink poison equal?

“饭后立即饮茶等于喝毒药！”最近，各大保健网上流传的这样一个观点受到不少饭后喜欢来一杯茶的老茶客的质疑。年近七旬的王先生就是其中一个。他说：“我20多年来都保持这种习惯，怎么没见我中毒？我不信！”王先生嗜茶如命，最近他觉得消化不良去医院看病，医生发现他有饭后马上喝茶的习惯后，劝他戒掉，并认为这是他致病的主要原因。他觉得这个说法没有依据：“你看广州哪家饭店不是饭前饭后都有茶喝的？要说这习惯不好，怎么还有那么多人天天叹早茶？”

　　对此，广州中医药大学第一附属医院刘友章教授认为，将饭后马上喝茶称为喝“毒药”虽然太过夸张，但是饭前饭后20分钟左右确实不宜大量饮茶，特别是饮浓茶。因为这样做的确会冲淡胃液，影响消化。他引用李时珍的观点说，茶性苦寒，适当饮茶，确能降火健身；但饮茶不当，非但对身体无益，还有可能伤身。中医认为“苦寒必伤脾胃”，过度饮茶首先会伤脾胃，“脾胃一伤，百病由生”。王先生消化不良，可能也跟他长期饭后喝茶有关。刘友章提醒，像王先生这样的老年人，应切记古人“淡茶温饮保年岁”的“良言”，饮淡茶、温茶才更有利于身体健康。
　　老年人饮茶 切记“淡茶温饮”
　　刘友章指出，作为饮料，茶被公认为是世界三大饮料(咖啡、可乐、茶)中最好的。从中医的角度看，茶具有清头目、利小便、去痰热、止渴、降火等功效，头痛上火的人，医生给他们开中药常会用茶叶为药引。
　　而现代医学对茶的研究则发现，喝茶能够抑制恶性肿瘤;茶多酚与咖啡因防止人体内胆固醇升高，防治心肌梗塞;茶多酚促使血管畅通，延缓和防止血管内膜脂质斑块形成，对动脉硬化、高血压、脑血栓有抑制作用；茶鞣酸能杀死多种细菌，对口腔炎、咽喉炎、肠炎、痢疾等都有防治作用。另外，饮茶能固齿明目，消肥健美，消暑解渴，更是任何饮料所不能比拟的。
　　“但凡事都过犹不及，茶的好作用再多，过度和不合理地饮用也会影响身体健康。那么，如何才能喝出健康呢?”刘教授称，其实李时珍在《本草纲目》早就提供了指导——李时珍认为“茶苦而寒，阴中之阴”，最能降火。而“火为百病”，火降则身体舒畅。但不同的人身上的“火”也有“虚实”之分，“少壮胃健之人，心肺脾胃之火多盛，故与茶相宜”；而“若虚寒及血弱之人，饮之既久，则脾胃恶寒，元气暗损”，甚至还会喝得“血不华色，黄卒萎弱”，造成种种内伤。他提醒，老年人消化功能有所减弱，饮茶时切记“淡茶温饮”四个字。他解释说，古人称“淡茶温饮保年岁”，就是强调要饮淡茶、温茶才更有利于老年人的身体健康。
　　六忌
　　刘教授称，茶要喝出健康，有不少讲究。他提醒，下列六种情况应忌茶。
　　1.忌饭前饭后大量饮茶
　　饭前饭后20分钟左右不宜饮茶，否则会冲淡胃液，影响食物消化。茶叶中含有大量鞣酸，鞣酸和荤腥食物中的蛋白质会合成具有收敛性的鞣酸蛋白质，使肠道蠕动减慢，易造成便秘。另外，空腹饮茶也会妨碍消化，甚至引起心悸、头痛、眼花、心烦等“茶醉”现象，严重的还会引起胃黏膜炎。正确的做法是：餐后一小时再喝茶，且不宜过浓。
　　2.体弱营养不良、贫血患者忌饮茶
　　茶叶有分解脂肪的功能，营养不良的人饮茶会分解脂肪，使营养更加不良。茶叶中的鞣酸可以与食物中的铁元素发生反应，生成难以溶解的新物质，使体内得不到足够铁的来源，时间一长引起人体缺铁，甚至诱发贫血症，故贫血患者不宜饮茶。


"Tea immediately after meals to drink poison equal!" Recently, the spread of major health-line of such a view by many after dinner to enjoy a cup of tea old tea drinkers questioned. Near seven-year old Mr. Wang is one of them. He said: "I have 20 years to maintain such a habit, not seen how my poisoning? I do not believe it!"

Mr. Wang tea Anopheles such as life, most recently he felt indigestion go to the hospital, doctors found that he has a cup of tea immediately after a meal of After the customary and advised him to quit, and think this is his main reason for pathogenicity. He feels that there is no basis for this argument: "Do you not watch Canton Restaurant which have tea before eating the meal? Say that bad habits, how there are so many people sigh morning every day?" In this regard, Guangzhou University of Traditional Chinese Medicine First Affiliated Hospital of Professor Liu Youzhang think, will be immediately after dinner to drink tea called "poison" Although, over exaggerated, but about 20 minutes before eating a meal is really not suitable to a large number of tea drinking, especially drinking concentrated tea. Because doing so would indeed dilute the gastric juice, affecting digestion. He cited Li's view that the cold tea, proper tea, can really Fitness to Reduce Pathogenic Fire; but tea properly, not only useless to the body, there may伤身.

Chinese medicine practitioners consider "must cold spleen injury," excessive drinking will hurt first of all the spleen and stomach, "one spleen injury riddled by Health." Mr. Wang indigestion, may also be a cup of tea after a meal with him on the long-term. Chapter Liu reminded, like Mr. Wang so the elderly, should bear in mind the ancients "淡茶Wen Bao drinking age" of the "good words",淡茶drinks, tea temperature is more conducive to good health. Remember the elderly tea "drinking temperature淡茶" Chapter Liu pointed out that as a beverage, tea is recognized as the world's three major beverages (coffee, cola, tea) the best. From the perspective of Chinese medicine, tea has a clearance leader,

ee urine to heat, thirst, Reduce Pathogenic Fire, such as efficacy, headache lit and the people, the doctors give them medicine to open for regular drug use tea primer. And modern medical research on tea is found that tea can inhibit tumor; Tea polyphenols and caffeine to prevent the human body elevated cholesterol, heart attack prevention; Tea polyphenols promote vascular smooth, slow down and prevent lipid plaque intima block the formation of atherosclerosis, hypertension, cerebral thrombosis have inhibition; tea tannin can kill a wide range of bacteria, of stomatitis, pharyngitis, enteritis, dysentery and others have preventive and therapeutic effects.

In addition, the tea can Mingmu Gu Chi, Xiao Fei aerobics, cool thirst-quenching, but also any drinks are not comparable. "But everything over too far, a good role of tea more, excessive and unreasonable manner consumption will also affect health. So how do we drink out of health?" Professor Liu said, in fact, Li Shizhen in the "Compendium of Materia Medica" is long overdue to provide guidance - Li Shizhen think "tea bitter and cold, yin of yin", the best to Reduce Pathogenic Fire. And "Fire for all diseases," the fire down the body at ease. However, different people's "Fire" also have "actual situation" of points, "Kin stomach of young people, cardiopulmonary Dorset Fire of the spleen and stomach, so affordable and Tea"; and "if the cold and the blood of the weak people, of both drink a long time, while the spleen and stomach恶寒, strength loss secret ", or even drunk" Blood does not Howard color, wilt黄卒weak ", causing all kinds of internal injuries. He reminded, the elderly have weakened digestive function, tea mind "淡茶warm drink" words. He explained that the ancients referred to as the "temperature淡茶drinking age security", is stressed the need to drink淡茶Wen Tea is more conducive to the health of the elderly. Six anti - Professor Liu said, a healthy drink tea, have a lot of stress. He reminded that the following six circumstances should avoid tea.

1. Bogey substantial meal before drinking 20 minutes before eating a meal should not be drinking, or else they will dilute the gastric juice, the impact of food digestion. Tea contains large quantities of tannic acid, tannin and protein in food荤腥will have a convergence of synthetic tannin protein, so that slow intestinal peristalsis, cause constipation. In addition, fasting tea also hinder digestion, and even cause palpitations, headache, vertigo, upset, such as "tea drunk" phenomenon also cause serious inflammation of gastric mucosa.

The correct way is: 1 hours and then a cup of tea after dinner, and not过浓. 2. Frail malnutrition, anemia in patients with free tea Tea has the function of fat decomposition, malnutrition tea will break down fat people, so that more bad nutrition. The tannic acid in tea can happen in food iron reaction, it is difficult to generate new substances dissolved so that the body is not enough source of iron, over time the human body caused by iron deficiency, and even induced anemia, it should not be drinking in patients with anemia tea.
