安溪铁观音成防疫天然屏障?院士刘仲华:茶叶可抑制新冠活性

泉州这一波疫情几乎席卷了下属所有县区市,唯独安溪例外。3月30日,泉州辖区新增确诊病例降至8例,无症状感染者121例,在来源地名单中,以盛产铁观音名扬天下的安溪县再次置身事外,仍然保持着零新增记录。


1铁观音成防疫的天然屏障?


泉州本轮疫情发生后,安溪已完成四轮全员核酸检测,结果均为阴性。


安溪自从打通连接同安的龙门隧道之后,可不闭塞。与周边县市多数已有高速公路直接相连,全县公路总里程5112公里,其中高速公路133公里,国省干线299公里,农村公路4680公里,公路总里程居全省县市区第一。


而今


2020年,安溪还规划了安翔、大安和安溪到龙岩三条高速公路,以实现乡镇30分钟可上高速。


但令人讶异,这种四通八达的交通环境并没有把安溪拖入到水深火热的疫情当中。安溪的周边城市已经历过多轮疫情反复,但安溪始终安之若素。即便有实施过封控的过程,但隔夜便撤销了。


当然不能否认,安溪的疫情防控水平与地方政府的“管理有方”密切相关。站在科学的角度,铁观音成为安溪防疫的天然屏障也不无道理。


安溪是铁观音的故乡,铁观音是安溪的主要经济作物。安溪现有人口120万,80%从事茶产业,茶产业收入占到安溪农民纯收入56%。进入县域,随处可见漫山遍野的茶山。


2茶叶中的甲基化EGCG和茶黄素


或许正是家家户户都有涉足茶产叶,为安溪抗疫立下了汗马之功。


中国工程院院士、湖南农业大学教授刘仲华曾经得出如是结论:茶叶中含有甲基化EGCG和茶黄素,可抑制新冠病毒的活性。而安溪铁观音中含有的甲基化EGCG和茶黄素更丰富,这导致安溪铁观音在抑制病毒、抗氧化能力和提高免疫力上更胜一筹。


安溪过去检测出的几个病例就证明了这种结论。


2020年新冠疫情暴发后,武汉输入2例,其中官桥1例,与家人同住,且与3位牌友通宵搓了麻将,但所有密接者均未被感染;2021年从厦门输入1例,有多位高度密接者,其中只检出1例阳性;2021年境外输入1例,全县零感染。


从后面的调查结果来看,这些密接者中,基本上每天都保持着喝安溪铁观音的习惯。


茶叶自古以来就被视为拥有解毒驱热的作用,2021年3月,中国营养协会联合中国医师协会发布的《新型冠状病毒感染的肺炎防治营养膳食指导》中,茶叶就受到特别礼遇。《指导》明确提出,患者应该每天饮用1500-2000ml茶水。


这就不难理解,天天与铁观音为伴的安溪人,在新冠疫情下,为什么有这么强的免疫力。

This wave of epidemics in Quanzhou has swept through almost all subordinate counties, districts and cities, with the exception of Anxi. On March 30, the number of newly confirmed cases in the Quanzhou area dropped to 8, and there were 121 asymptomatic infections. In the list of origins, Anxi County, famous for its rich production of Tieguanyin, was out of the way again and still maintained a record of zero new additions.


1Is Tieguanyin a natural barrier for epidemic prevention?


After the outbreak of the epidemic in Quanzhou, Anxi has completed four rounds of nucleic acid tests for all staff, and the results were all negative.


Since the opening of the Longmen Tunnel connecting Tong'an, Anxi has not been blocked. It is directly connected with most of the existing expressways in surrounding counties and cities. The total mileage of highways in the county is 5,112 kilometers, including 133 kilometers of expressways, 299 kilometers of national and provincial trunk lines, and 4,680 kilometers of rural roads.

In 2020, Anxi also planned three expressways from Anxiang, Da'an and Anxi to Longyan, so that the township can be connected to the expressway within 30 minutes.


But it is surprising that this well-connected traffic environment did not drag Anxi into the raging epidemic. The surrounding cities of Anxi have experienced many rounds of repeated epidemics, but Anxi has always been at peace. Even though there was a process of implementing the lockdown, it was withdrawn overnight.


Of course, it cannot be denied that the level of epidemic prevention and control in Anxi is closely related to the "proper management" of the local government. From a scientific point of view, it is not unreasonable for Tieguanyin to become a natural barrier for Anxi's epidemic prevention.


Anxi is the hometown of Tieguanyin, and Tieguanyin is the main economic crop of Anxi. Anxi has a population of 1.2 million, 80% of which are engaged in the tea industry, and the income of the tea industry accounts for 56% of the net income of farmers in Anxi. Entering the county, you can see tea hills everywhere.


2 Methylated EGCG and theaflavins in tea


Perhaps it is every household who is involved in tea production, which has made great contributions to Anxi's fight against the epidemic.


Liu Zhonghua, academician of the Chinese Academy of Engineering and professor of Hunan Agricultural University, once concluded that tea contains methylated EGCG and theaflavins, which can inhibit the activity of the new coronavirus. The methylated EGCG and theaflavins contained in Anxi Tieguanyin are more abundant, which makes Anxi Tieguanyin better in inhibiting virus, antioxidant capacity and improving immunity.


Several cases detected in Anxi in the past support this conclusion.


After the outbreak of the new crown epidemic in 2020, 2 cases were imported from Wuhan, including 1 case in Guanqiao, who lived with his family and played mahjong overnight with 3 players, but all the close contacts were not infected; 1 case was imported from Xiamen in 2021, There are many highly close contacts, of which only 1 case is positive; 1 case is imported from abroad in 2021, and the county has zero infection.


Judging from the results of the investigation later, these close contacts basically maintained the habit of drinking Anxi Tieguanyin every day.


Tea has been regarded as having the effect of detoxification and expelling heat since ancient times. In March 2021, in the "Nutritional Dietary Guidelines for the Prevention and Treatment of Pneumonia Infected by Novel Coronavirus" issued by the Chinese Nutrition Association and the Chinese Medical Doctor Association, tea received special courtesy. The "Guidance" clearly states that patients should drink 1500-2000ml of tea every day.


It is not difficult to understand why people from Anxi who are with Tieguanyin every day have such strong immunity under the new crown epidemic.
