What they are eating, exactly, what are they eating
對(duì)，羊吃什么呢
They are eating these little tiny grasses that have to work really hard to grow
他們吃的是當(dāng)?shù)仄D難生長(zhǎng)的小草
and it turns out when vegetables have a lot adversity and to work really hard to make it above the earth
一般而言，當(dāng)植物生長(zhǎng)于逆境時(shí)
They're filled with things that are good for you
就會(huì)含有很多有益物質(zhì)
and filled with something called alpha linolenic acid
會(huì)含有一種叫α-亞麻酸的物質(zhì)
which I don't know if they talked about this the other day
我不知道，之前有人講過(guò)沒
It's actually the precursor to eicosapentaenoic acid which is the omega-3 fats in fish
它是十二碳五烯酸的前體，也就是魚中的ω-3脂肪酸
We can pretty much do a decent job, most of us, unless some real genetic problem of converting that as can lambs to the omega-3 fats form
除了部分基因方面的東西以外，我們能同羊羔一樣將這些植物轉(zhuǎn)化為ω-3脂肪
So it turns out that that's where they are getting it
這就是來(lái)源
And if you look at the research and this is out of UC Davis
再看一項(xiàng)加大戴維斯分校的研究
all of a sudden we traveled from Iceland to the Central Valley here
突然就從冰島回到美國(guó)中央谷地了
And you look grain fed beef versus
這里對(duì)比了谷物飼養(yǎng)的牛
free range animals who're kind of equivalent to the Icelandic sheep, except maybe not getting as much as the Icelandic sheep
和放養(yǎng)動(dòng)物，類似冰島羊，只是可能沒冰島羊那么好
What do you see is the difference in their omega-3 fat levels between all these free range or wild animals and the corn fed confined beef
對(duì)比了兩者肉中的ω-3脂肪水平，放養(yǎng)或野生動(dòng)物和玉米飼養(yǎng)的圈養(yǎng)牛有什么不同
More omega-3s, yeah, any other observations
放養(yǎng)動(dòng)物ω-3更多，還有呢
Oh, isn't that astounding? Isn't it?
哦，很驚人，不是嗎
Yeah, it's so interesting. Yeah, and monounsaturated too. Yeah, it's really quite interesting
對(duì)，很有趣，放養(yǎng)動(dòng)物單不飽和脂肪少很多
So, Yeah, the other fats sort of match up the same
其它脂肪都幾乎相同
but those are the really interesting ones
這兩點(diǎn)尤為不同
