Here's the latest looking at prostate cancer cell growth.

這是前列腺癌細胞生長的最新資訊。

The United States has the highest rate of prostate cancer in the world, so let's try a native American fruit.

美國是世界上前列腺癌發病率最高的國家，所以我們就用美國本土品水果來做測試。

Researchers started out with about 50,000 human prostate cancer cells in a petri dish, and if you do nothing, within a day you're closer to 100,000, then 200,000, then nearly 400,000 within 72 hours.

研究員從培養皿中 5 萬個人類前列腺癌細胞著手研究。如果你什麼都不做，癌細胞在一天之內會增殖為 10 萬個，接著是 20 萬個，並在 72 小時內增殖近 40 萬個。

But by adding just a smidgen of cranberries, or two smidgens, you can see they block that exponential cancer growth.

但只要加入少量或一些的蔓越莓，就能抑制癌細胞的增長。

The reason they tested such tiny concentrations, is that we only absorb a small fraction of the cranberry phytonutrients we eat into our bloodstream.

他們用如此低的濃度進行測試，主要是因為我們攝取的蔓越莓植物營養素，只有極少量能被血液吸收。

Still, cranberries are cheap.

但是蔓越莓很便宜。

If drug companies and supplement manufacturers are going to capitalize on this, they needed to find cranberry's active ingredient.

如果製藥公司和營養補給品生產商打算以此營利，他們得找到蔓越莓的活性成分。

Here's some of the various phytonutrients in cranberries.

這些是蔓越莓中的植物營養素。

So different fractions were tested against various types of cancer to find the magic bullet.

為了找到靈丹妙藥，他們針對不同的癌症進行了不同劑量的測試。

Yes, the anthocyanin phytonutrients inhibit colon cancer cell proliferation about 15% for example, about the same with the proanthocyanidins fraction, but nothing compared to the total cranberry extract of the whole fruit.

是的，舉例來說，花青素植物營養素能抑制約 15% 的結腸癌細胞增殖。其功效與原花青素相似，但與以整顆蔓越莓萃取而成的精華相差甚遠。

There seemed to be an additive or synergistic antiproliferative effects, resulting from a combination of the various components compared to individual purified phytochemicals".

這似乎存在累加或增效抗增殖效應，歸因於各種成分的組合，與個別純化植物素形成對比。

So it's always better to eat the whole fruit.

所以食用整顆水果總是比較好的。

How do you do that with cranberries, though?

但是蔓越莓怎麼整顆吃？

Although 5% of cranberries are sold fresh, the vast majority are consumed as processed products.

雖然有 5% 的蔓越莓是新鮮出售的，但大多數都是經過加工的蔓越莓產品。

To get the same amount of anthocyanin phytonutrients in a cup of fresh or frozen cranberries, you'd have to drink 16 cups of cranberry juice cocktail, eat 7 cups of dried cranberries, or 26 cans of cranberry sauce.

若要從一杯新鮮或冷凍的蔓越莓中獲得等量的花青素植物營養素，你得喝 16 杯蔓越莓雞尾酒、吃 7 杯蔓越莓乾或 26 罐蔓越莓醬。

The problem is that raw cranberries are so tart that folks may opt for the dried.

問題是生蔓越莓太酸了，人們可能會選擇蔓越莓乾。

In a taste test survey, consumers said they wouldn't mind eating sweetened cranberries every day, whereas raw cranberries sloped down towards maybe once a year.

在一項口味測試調查中，消費者表示他們願意每天吃甜的蔓越莓，但生的蔓越莓可能一年吃一次。

The problem is dried cranberries tend to come sweetened.

問題是蔓越莓乾通常添加了甜味劑。

Raw cranberries don't affect your blood sugar, but sweetened dried cranberries do, even the low-sugar varieties.

生蔓越莓不會影響你的血糖，但添加甜味劑的蔓越莓乾，即使是低糖也會影響血糖。

What about cranberry juice, or shall I say quote, unquote juice?

那蔓越莓汁呢，或者我該說「果汁」更貼切？

Cranberry cocktail is only about a quarter cranberry juice.

在蔓越莓雞尾酒中，蔓越莓汁只佔了四分之一。

The ruby red phytonutrients in cranberries and pure cranberry juice are powerful antioxidants, increasing the antioxidant capacity of our bloodstream within hours of consumption.

蔓越莓中的紅寶石色植物營養素和純蔓越莓汁皆為強大的抗氧化劑。食用數小時內就能增加我們血液的抗氧化能力。

But the high fructose corn syrup acts as a pro-oxidant, even if you add vitamin C to it as they did here, canceling out some of the cranberry benefit.

但是高果糖玉米糖漿為助氧化劑。即使添加維他命 C，仍然會削弱蔓越莓的功效。

So how do you get the upsides without the down?

所以如何去蕪存菁呢？
