咖啡：血管衛士還是心髒殺手？

　　咖啡作爲越來越被大衆所喜愛的飲品之一，其作用卻一直飽受爭議。人們爭論的焦點在于這種含有咖啡因的飲料對人類的心血管到底有沒有益處，這一激烈爭論自從咖啡的理化性質被解析以來就一直存在。

　　最近來自韓國的科學家公布了一項研究，他們發現飲用咖啡能夠降低血管阻塞的風險。研究人員通過對2.5萬受試者的調查發現，每天飲用3—5杯咖啡的人患心血管疾病的風險更低。

　　長期以來，醫學工作者通過使用血管造影術等方法來試圖爲這一問題蓋棺定論，但卻得出了截然不同的結論。有些實驗表明咖啡會導致血液中膽固醇水平升高以及血壓上升，進而增大患上心髒病的風險；而另一些研究人員卻稱咖啡具有保護心髒的作用。

　　此次韓國科學家的這一研究則采用了不同的研究指標。前期研究發現，人體血管中會出現不同程度的鈣沈積，這種沈積的程度與心髒病的發病有著密切聯系。研究人員在調查中發現，許多沒有心髒病病史的受訪者血管內部也存在這種沈積。因此，研究人員著重調查了這種鈣沈積與咖啡飲用量之間的關系，並最終得出這一結論。

　　不過，研究人員同時表示他們還需要進一步驗證這一結論。

　　咖啡中的咖啡因被認爲對大腦有刺激作用，但咖啡因同時也引發了許多人對于咖啡是否健康的爭論。

　　不同國家的健康專家對這一問題的看法也不盡相同。

　　美國的營養學專家曾建議每人每天攝入的咖啡因含量不應大于400毫克，英國則認爲除了孕婦之外，不必限定人們攝入咖啡因的量。而孕婦攝入的咖啡因則應控制在200毫克以下，即每天飲用不超過兩杯速溶咖啡。

"We walked by the side of our teams or behind the wagons, we slept on the ground at night, we did our own cooking, we washed our knives by sticking them into the ground rapidly a few times, and we washed our plates with sand and wisps of grass. When we stopped, we arranged our wagons in a circle, and thus formed a 'corral,' or yard, where we drove our oxen to yoke them up. And the corral was often very useful as a fort, or camp, for defending ourselves against the Indians. Do you see that little hollow down there?" he asked, pointing to a depression in the ground a short distance to the right of the train. "Well, in that hollow our wagon-train was kept three days and nights by the Indians. Three days and nights they stayed around, and made several attacks. Two of our men were killed and three were wounded by their arrows, and others had narrow escapes. One arrow hit me on the throat, but I was saved by the knot of my neckerchief, and the point only tore the skin a little. Since that time I have always had a fondness for large neckties. I don't know how many of the Indians we killed, as they carried off their dead and wounded, to save them from being scalped. Next to getting the scalps of their enemies, the most important thing with the Indians is to save their own. We had several fights during our journey, but that one was the worst. Once a little party of us were surrounded in a small 'wallow,' and had a tough time to defend ourselves successfully. Luckily for us, the Indians had no fire-arms then, and their bows and arrows were no match for our rifles. Nowadays they are well armed, but there are[Pg 41] not so many of them, and they are not inclined to trouble the railway trains. They used to do a great deal of mischief in the old times, and many a poor fellow has been killed by them." The boys looked in the direction indicated, but could see nothing. This is not surprising, when we remember that sailors' eyes are accustomed to great distances, and can frequently see objects distinctly long before landsmen can make them out. Mr. Charlton's melancholy eyes seemed to be fixed on space. Just for the moment he had forgotten that he was not alone. Lawrence gave a sympathetic cough. As a matter of fact, he had not yet explained what he was doing there, and the longer the explanation was postponed the better he would be pleased. "You see our patient has gone," Balmayne said smoothly. "As a matter of fact, the whole thing was a ridiculous mistake. But you must not blame us. The blame is due to the charming young lady who sent for you. But that is one of the drawbacks of your noble profession. Goodnight." In one of the inmost circles, a sacred elephant had gone must, breaking his ropes, and confined now by only one leg. The chains fastened round his feet as soon as he showed the first symptoms of madness were lying broken in heaps on the ground. The brute had demolished the walls of his stable and then two sheds that happened to be in his way; now he was stamping a dance, every muscle in incessant motion, half swallowing his trunk, flinging straw in every direction, and finally heaping it on his head. A mob of people stood gazing from a distance, laughing at his heavy, clumsy movements; at the least step forward they[Pg 113] huddled back to fly, extending the circle, but still staring at the patient. In an adjoining stable were two more elephants very well cared for, the V neatly painted in red and white on their trunks, quietly eating and turning round only at the bidding of the driver; but one of them shed tears. The rajah's sleeping-room has at one end a dais ascended by three steps; here the sovereign's bed used to be spread; and here, now, the judges of the Supreme Court have their seats. In the middle of the room was a confused array of benches and tables, and against the walls, also washed with yellow, hung a series of portraits of bewigged worthies. No new clues offered themselves. He detached one of the hard, adhering chunks of gum and dropped it into his pocket, “just in case,” he said, half-grinning, “just in case they transfer themselves somewhere else. I’ll leave twenty-nine of them—and see.” The Lieutenant and Si and Shorty tried to make themselves believe that the noise was receding, showing that the rebels were being driven. At times it certainly was so, and then again it would burst out, Naturally, the boys were big-eyed all the time with the sights that filled the landscape near and far. Wherever they looked they were astonished, and when in a march they came out on a crest that commanded a wide view, they could not help halting, to drink all its wonders in. Even the experienced Si and Shorty were as full of amazement as they, and watched with fascination the spectacle of mighty preparation and concentrated power. "It has a great deal to do with this lecture with which you have favored us," answered the Major dryly. "But we'll not discuss that in open court. Are you through with the witness, Judge-Advocate? If so, call the next." "But I'm not going to leave you alone to brood," Albin said. "Because I'm your friend. And brooding isn't good for you. It's brooding that's got you into such a state—where you worry about growing things, for God's sake, and about freedom and silly things like that." Albin grinned. "What you've got to do is stop worrying, and I know how to get you to do that, kiddo. I really do." "Where may I learn the others?" But Gornom didn't answer, and Cadnan's breathing-space was over. He had to be back at the board, pushing buttons, watching carefully. Gornom stood behind him, peering over his shoulder with a cloudy eye. Neither said a word until the new spell of work was over. Then Cadnan repeated his question. He had become separated from the other searchers, and was alone on the west side of the Moor. The wind barked and howled, hurling itself upon him as he stood, beating his face with hail, which hissed into the dead tangles of the heather, while the stripped thorns yapped and rattled, and the bushes roared. So great was the tumult that he seemed to fall into it like a stone into a wave—it passed over him, round him, seemed even to pass under him, he was hardly conscious of the solid ground. The blackness was impenetrable, save where his lantern stained it with a yellow smudge. He shouted, but his voice perished in the din—it seemed as if his whole man, sight, voice, hearing, and sensation, was blurring into the storm, as if Boarzell had swamped him at last, made him merely one of its hundred voices, mocking the manhood which had tried so much against its earth. While the guide paused for a moment to recollect the way to the head-quarters of the insurgents, some one who passed was heard speaking in a tone which fell upon Stephen's ear like a sound he ought to remember; he sprang from the side of his comrades, and, standing before the strangers, demanded, "With whom hold you?"
