Spinach: The Hype◆ and New Research　誤會大了！其實菠菜含鐵量少十倍

　　If someone has ever advised you to eat spinach to boost your iron intake◆, they’re probably basing their advice on the same flawed study that prompted cartoon character Popeye to gobble up the green vegetable. You have to go back to the 19th century to “get to the bottom of this.” In 1870, German chemist◆ Erich von Wolf figured out the amount of iron in spinach. However, while recording his finding, he misplaced the decimal point◆. Rather than writing that spinach had 3.5 milligrams◆ of iron per 100-gram serving◆—which is the accurate measurement—he wrote that it had 35 milligrams. Author and scientist Samuel Arbesman has noted that this “would be like eating a small piece of a paper clip.”
　　Surprisingly, no one noticed this mistake for 70 years, by which point the public viewed spinach as an iron superfood◆. This concept was used in the creation of the cartoon character Popeye the Sailor, who would develop superhero strength whenever he ate a can of spinach. Today, decades after the correction, many still believe spinach to be far richer in iron than it really is.
　　While the public have been slowly digesting spinach’s less-than-stellar◆ iron status, scientists have continued studying the leafy◆ green and have come up with a new health claim. According to researchers from Freie Universität Berlin, spinach contains the hormone◆ ecdysterone◆, which may be similar to steroids◆. In studying the effects ecdysterone had on athletes, the scientists found that those taking pills with the hormone had higher increases in muscle mass◆ and better performance in weightlifting◆. While the hormone present in spinach isn’t currently a banned substance◆ for athletes, the news of it does seem to be bringing us back to the age-old question: Is spinach an ordinary vegetable or a strength-giving food?

誤會大了！其實菠菜含鐵量少十倍
　　

　　如果曾有人建議你吃菠菜來增加鐵的攝取量，那麼他們可能是基於同一個有瑕疵的研究，該研究促使卡通人物卜派狼吞虎嚥吞下這種綠色蔬菜。你必須回到十九世紀才能找到這個問題的真相。1870 年，德國化學家埃里希．馮．沃爾夫算出了菠菜中的鐵含量。然而，在記錄他的發現時，他將小數點的位置放錯了。他把每份一百克菠菜的含鐵量寫成了「三十五」毫克而不是 3.5 毫克（這是正確的測量值）。作家暨科學家山謬．阿貝斯曼指出，這「會像是吃了一小段迴紋針一樣。」
　　令人意外的是，七十年來沒有人注意到這個錯誤，此時大眾已將菠菜視為一種含鐵的超級食物。這個概念被用來創造出卡通人物大力水手卜派，每當他吃下一罐菠菜就能擁有超級英雄的力量。歷經錯誤更正後數十年的現在，許多人仍然認為菠菜中的鐵含量遠高於其實際含量。
　　當大眾慢慢理解菠菜的鐵含量不怎麼出色的同時，科學家已持續對這種綠葉蔬菜進行研究並提出新的健康主張。根據柏林自由大學的研究人員所言，菠菜中或許含有類似於類固醇的激素 ── 蛻皮甾酮。在研究蛻皮甾酮對運動員的影響時，科學家發現那些服用含有此激素之藥丸的運動員，其肌肉量增加更多，舉重的表現也更好。雖然這種在菠菜中的激素目前不是運動員禁用的物質，但有關它的消息似乎確實帶我們回到一個由來已久的問題：菠菜是普通的蔬菜還是增強力量的食物？
---------------------------------
1. 誰是大力水手卜派？
(A) 一個天生具有超人力量的人。
(B) 一名研究菠菜的水手暨科學家。
(C) 一個菠菜罐頭公司的吉祥物。
(D) 一名出自卡通的虛構人物。
---------------------------------
2. 第一段的 “get to the bottom of this” 指的是什麼？
(A) 探索為什麼人們錯誤地認為菠菜的含鐵量比實際的高。
(B) 查明為什麼菠菜擁有的鐵比其他任何蔬菜還多。
(C) 查明為什麼馮．沃爾夫決定要研究菠菜。
(D) 了解為什麼卜派這麼喜歡菠菜。
---------------------------------
3. 現在科學家表明菠菜擁有什麼功效？
(A) 它可以使人大幅減重。
(B) 它可以增強人的肌肉。
(C) 它會導致高血壓。
(D) 它可以提升賽跑的成績。
---------------------------------
4. 作者對於菠菜的態度為何？
(A) 生氣的。 (B) 中立的。
(C) 厭惡的。 (D) 熱衷的。
答案：1. D　2. A　3. B　4. B

•寄生上流翻身股
雖然面臨武漢肺炎疫情擴大衝擊，一度對美股和全球股市造成回檔壓力，但美國經濟被疫情波及的情況仍受到控制，聯準會主席鮑威爾也認為暫時不需要降息等於是替第一季美國經濟成長背書，激勵美股再創歷史新高。

•新冠肺炎的最糟情境
Ｈ１Ｎ１流行時，當確診病患以萬名計，就不再追蹤可能接觸者，只能加強全民個人防護，全力醫治病患，減少死亡。台灣的新冠疫情已逐漸進入社區大量感染併院內感染的階段，必須有所準備。期待最糟情境不會發生。
