雅艾爾：想喝點豆?jié){嗎，唐?

Don: I'll pass, thank you.

唐：不用，謝謝。

Yael: What about some of this tofu salad?

雅艾爾：來點豆腐沙拉怎么樣?

Don: Why are you pushing soy foods on me?

唐：為什么你老是向我推薦豆制品?

Yael: Because it turns out that there is yet anotherbenefit to consuming soy, and this benefit is formen specifically. When digested, soy creates amolecule called equol, which blocks the male hormone dihydrotestosterone, otherwise knownas DHT.

雅艾爾：因為事實證明食用豆制品另有益處，對男人更是如此。在消化時，豆類會產(chǎn)生一種雌馬酚分子，這種分子會阻礙男性分泌DHT(雙氫睪酮激素)。

Don: Hold up there. Why on earth would I want to consume something that will block myprecious male hormones? Aren't those important?

唐：等一下。到底為什么我要吃這種對我寶貴的雄性激素有害的東西?我的性激素難道不重要嗎?

Yael: Down boy! Testosterone does serve important functions, but DHT is not so desirable,considering its involvement in prostate cancer. The pharmaceutical industry has focused a lotof energy into developing drugs that do what soy does naturally. Except the problem is that thedrugs created to fight prostate cancer don't just affect DHT, but they affect testosterone too.These drugs inhibit testosterone from converting into DHT. In doing so, they not only reducethe harmful effects of male hormones, but they reduce the beneficial effects of thesehormones too.

雅艾爾：坐下，伙計!睪丸素的功能的確很重要，但考慮到它與前列腺癌有關(guān)，DHT就不那么值得擁有了。制藥行業(yè)集中大量精力投入到開發(fā)藥品上去，但得到的效果與天然的大豆相差無幾。但有一個問題，用來抵抗前列腺癌的藥物不僅會影響DHT,還會影響睪丸素。這些藥物阻止睪丸素轉(zhuǎn)化為DHT。這樣，它們雖然減小了雄性荷爾蒙的有害影響，但也阻礙了這些激素的有益影響。

Common side effects of these drugs include reduced libido, impotence, decrease in musclestrength, and an increased risk of osteoporosis. What's so promising about soy is that itdoesn't prevent the conversion of testosterone into DHT, but instead blocks DHT fromfunctioning once it's made. The result is that soy prevents DHT from doing its damage withoutblocking the beneficial effects of male hormones. Scientists think that because of its effects onDHT, soy may prove beneficial in treating other conditions associated with DHT, such as malepattern baldness.

這些藥物的副作用通常包括降低性欲，陽痿，肌肉無力，增加骨質(zhì)疏松的風(fēng)險。大豆前景那么廣闊的原因在于它并不阻礙睪丸素轉(zhuǎn)換為DHT，恰恰相反，它阻礙DHT發(fā)揮應(yīng)有的作用。因此大豆能防止DHT危害人體，同時保證雄性荷爾蒙對人體的有益影響。考慮到大豆對DHT的影響，科學(xué)家們認為大豆可能有利于治療其它與DHT有關(guān)的病癥，例如男性模式脫發(fā)。

Don: On second thought, how about you pass that tofu over this way?

唐：經(jīng)過重新考慮，你還是把豆腐遞到這邊來吧。
