绿茶、乌龙茶 普洱茶 高血压喝茶的4个禁忌

高血压患者可以选择绿茶、乌龙茶和普洱茶。

很多朋友纠结到底该喝红茶还是绿茶？两者有何区别呢？红茶属于发酵茶叶，是以茶树的芽叶为原料，经过萎凋、揉捻、发酵、干燥等典型工艺过程精制而成。经发酵后的红茶的茶多酚大约降低90%，并产生了茶黄素、茶红素等新成分。而绿茶，属未发酵茶，在加工过程中，绿茶的茶多酚大约保留了90%，含有较多的茶多酚、儿茶素、叶绿素、咖啡碱、氨基酸、维生素等多种营养成分。红茶和绿茶各自所含主要成分的区别在于茶多酚的含量上。

饮茶对降血脂、血压及胆固醇的水平，预防心血管事件的发生有一定的保健作用。茶叶中的茶多酚，特别是儿茶素具有降脂和保护毛细血管的作用，有助于软化血管。绿茶与红茶的茶多酚含量有一定的差距，前者茶多酚含量高些，可能对血压的影响大些；而后者经发酵后茶多酚含量降低，对血压影响较小些。高血压患者可以选择乌龙茶、绿茶、普洱茶等。

但需要注意的一点是，茶叶对血压的影响的真实性还有待考证，目前有很多宣称喝茶可以降血压的信息，但其实并没有发现茶可以直接降血压。对于大部分的高血压患者来说，无论饮茶与否，正规的治疗才是控制血压必不可少的。坚持正确的生活方式，保持低脂、低盐的饮食习惯，戒烟戒酒、规律作息，坚持血压监测以及遵医嘱用药，方能稳定血压水平，减少并发症的发生。

另外，关于茶叶中的咖啡因会升高血压的问题一直存在争议。对于喜欢喝茶的人来说，如果平时监测血压的时候没发现茶对血压造成影响，就可以继续喝，但同样不要对喝茶降血压抱有太大期望。

高血压喝茶的4个禁忌

1、不要喝浓茶

高血压患者可以适当饮茶，但不宜喝浓茶，因为浓茶中的咖啡碱，可以兴奋中枢神经，使许多人出现兴奋、失眠、心率加快等症状，这样会增加心脏的负担，对高血压病人不利。2、睡前不宜喝茶

高血压患者要注意晚间不宜喝茶，茶有提神兴奋、利尿的作用。如果过晚喝茶会导致兴奋性提升，容易导致失眠，影响睡眠质量。

3、特殊人群不宜饮茶

长期大量饮茶，茶叶中的鞣酸会阻碍铁的吸收，有营养不良以及缺铁性贫血患者不适合喝茶，另外患有溃疡病患者不适合喝茶。

4、吃药时不要饮茶

吃药时最好不用茶叶水送服，因为茶叶中含有多种成分，很可能会与药物发生反应，产生副作用，加重肝肾负担，不仅起不到治疗效果，还可能会损伤身体健康。最好在吃药后一小时后再喝茶。

Hypertensive patients can choose green tea, oolong tea and Pu-erh tea.

Many friends are confused about whether to drink black tea or green tea? What is the difference between the two? Black tea belongs to fermented tea, which is refined from the buds and leaves of tea trees through typical processes such as withering, rolling, fermentation and drying. The tea polyphenols of the fermented black tea are reduced by about 90%, and new components such as theaflavins and thearubigins are produced. Green tea is an unfermented tea. During the processing, about 90% of the tea polyphenols of green tea are retained, and it contains more tea polyphenols, catechins, chlorophyll, caffeine, amino acids, vitamins and other nutrients. The difference between the main components of black tea and green tea is in the content of tea polyphenols.

Drinking tea has a certain health care effect on lowering blood lipid, blood pressure and cholesterol levels and preventing the occurrence of cardiovascular events. Tea polyphenols in tea leaves, especially catechins, have the effect of lowering lipids and protecting capillaries, helping to soften blood vessels. There is a certain gap between the content of tea polyphenols in green tea and black tea. The former has a higher content of tea polyphenols, which may have a greater impact on blood pressure; while the latter has a lower content of tea polyphenols after fermentation, which has less impact on blood pressure. Hypertensive patients can choose oolong tea, green tea, Pu'er tea, etc.

However, it should be noted that the authenticity of the effect of tea on blood pressure has yet to be verified. At present, there is a lot of information claiming that drinking tea can lower blood pressure, but in fact, it has not been found that tea can directly lower blood pressure. For most hypertensive patients, regular treatment is essential to control blood pressure, whether drinking tea or not. Adhere to a correct lifestyle, maintain a low-fat and low-salt diet, quit smoking and drinking, work and rest regularly, adhere to blood pressure monitoring, and follow the doctor’s prescription to take medicines, in order to stabilize blood pressure levels and reduce the occurrence of complications.

In addition, there has been controversy over the fact that caffeine in tea can increase blood pressure. For people who like to drink tea, if they do not find that tea has an effect on blood pressure when monitoring blood pressure, they can continue to drink it, but also don't have too much expectations for drinking tea to lower blood pressure.
