別「趁熱喝了」

喝太高溫的熱茶，小心引發食道癌。
英國某醫學期刊的研究發現，在伊朗，專家發現一個全球食道癌罹患率最高的地方，深入調查後發現，很可能是當地人每天必須喝 1公升的熱紅茶有關，研究還指出，喝70度高溫的茶，罹患食道癌的機率增加8倍。
所以，以後喝茶、喝湯，別再跟朋友說「趁熱喝」了。
因為國外最新研究發現，喜歡喝70度以上熱飲者，罹患食道癌的機率比喝溫飲者高8倍，熱飲傷害喉嚨組織，現在也被視為是食道癌的危險因子之一。
100度高溫熱水沖入茶杯中，熱氣、香氣迅速飄散開來，但這時可別急著喝，因為喝 70度以上的熱飲，罹患食道癌的機率比喝溫飲者高出8倍，即使是喝65度到69度熱飲，罹患食道癌的機會也比喝溫飲者高出1倍，意即不論喝熱茶、咖啡，還是湯品，最好還是多點耐心，再忙、再餓、再渴，都要多等個幾分鐘再喝吧！
滾燙的熱湯、剛泡好的熱茶，趁熱喝，小心給「燙」出食道癌！
從學理看，高溫的確對食道有害，研究更指出，常喝65度到69度之間的熱飲，致癌機會是65度的2倍；70度以上，風險更提高為8倍，以沖泡時間來看，泡完2分鐘就喝，比起4-5分鐘後再喝，致癌風險5倍。
這項研究剛登上英國醫學期刊，究竟民眾該怎麼看待？
北醫耳鼻喉科主任趙品植：「喝熱飲的的溫度太高的話，會造成黏膜破壞，反覆黏膜破壞的話，會造成食道細胞癌化的可能性。」
趙品植：「通常人體溫度大概38度左右，所以我們希望熱飲盡量不要超過60度或70度。」
剛沖到杯子裡的熱水，實際測量大約80多度，放在正常室溫下，過了幾分鐘，溫度終於降到65度，不過醫師認為，只要不覺得「燙口」就好，對於已經喜好抽菸、喝酒的食道癌高危險群，更是要避免雪上加霜，增加罹癌風險。

My programmer is trying to convince me to move to .net from PHP. I have always disliked the idea because of the costs. But he’s tryiong none the less. I’ve been using Movable-type on a variety of websites for about a year and am anxious about switching to another platform. I have heard good things about blogengine.net. Is there a way I can import all my wordpress posts into it? Any kind of help would be greatly appreciated!
Fantastic website. Plenty of useful information here. I?m sending it to a few friends ans also sharing in delicious. And of course, thank you to your effort!
Discovering The Writing has been a game-changer for me. The contributions are invaluable.
This article was a joy to read. The enthusiasm is contagious!
I learned so much from this post. The ability to break down hard to understand ideas is something I really admire.
You really make it seem so easy with your presentation but I find this matter to be really something which I think I would never understand. It seems too complex and extremely broad for me. I’m looking forward for your next post, I will try to get the hang of it!
The work is both informative and thought-provoking. I’m really impressed by the high quality of The content.
You navigate through topics with such grace, it’s like watching a dance. Care to teach me a few steps?
