With the advent of freezers,
we're able to keep our food lasting longer than ever before.
But is there a difference between fresh and frozen produce in terms of nutrition?
Which should you be eating?
Your instinct may be to shout out, "Of course fresh food is better!"
"It's fresh!"
And you may be right, but it's highly dependent on the circumstances.
In many instances, the food you take off the shelf in a grocery store
has been harvested under-ripe to avoid damage during travel time.
This means it hasn't yet reached its peak nutrition.
Furthermore, the minute it was picked, its nutritional content began to deteriorate.
The food is then loaded on a truck, boat or plane,
travels for days, and waits on a shelf for you to choose it.
Afterwards, it may sit in your fridge for a few more days before being eaten.
Over this period of potentially weeks, the food may lose
up to 50 percent of its nutritional value.
Frozen foods, on the other hand, are picked when they're ripe
and frozen immediately.
And while the quick freeze process does affect some of the vitamin content
it essentially freezes, or locks, most of the nutrients in place.
Next to the fresh produce that has been sitting around for weeks,
there's no doubt that frozen foods can contain more nutrition.
Particularly during the month that local produce is not in season and travelling far distances.
In a series of studies, after three days of storage,
frozen broccoli had higher levels of Vitamin C and Beta-Carotene,
frozen blueberries were much higher in polyphenols and anthocyanins,
and frozen sprouts scored higher on all nutrient measurements.
Of course, if you pick a fresh vegetable from your garden,
or get it from a local farmer's market, and eat it that date,
nothing can quite compare to both the nutrition and the taste.
But, unless you're able to shop every few days, frozen produce
can be a great nutritionally comparable alternative.

影片簡介

展開內容
在大部分人的觀念裡,「冷凍食品」就是不新鮮的代名詞,而新鮮食材似乎在各方面都勝過冷凍食品,但這部影片要打破這樣的迷思!告訴大家,其實冷凍食品並沒有我們想的那麼糟,甚至在某些情況下,購買冷凍食材才是更好的選擇!

1instinct0:10
instinct 是「本能、天性」的意思,影片中「Your instinct may be to shout out...」意思就是「你的直覺會認為...」
The natural instinct of the human body is to throw out all invaders.
人體的自然本能是排除一切入侵物。

2circumstances0:16
circumstance 有「境遇、情況、事實」的意思,常以複數形態出現,如果我們想說「在不同的情況之下」就可以用「in/under different circumstances」。而同樣有「情況」的意思的單字,還有 situation、condition 等等,但 situation 通常是指一個局面或是特定情況,而 condition 則強調人事物在某時期所處的特定環境或狀態。
I think she coped very well under the circumstances.
我認為她在這樣的情況下處理得非常好。

3deteriorate0:31
deteriorate 有「惡化、變壞」的意思,在這裡指的是營養「流失」。
Rubber is a standard insulating material but it is able to deteriorate under the sun.
橡膠是標準的絕緣物質,但它在陽光下容易老化。

你所不知道的「沮喪」科學! (The Science of Depression)


4alternative1:36
alternative 有形容詞「替代的、其他的」的意思,作為名詞則是「替代品」的意思。在影片裡是後者。
They had no alternative in the matter.
在這件事上,他們沒有選擇的餘地。


*同場加映:
Alain de Botton:一種更寬容,更溫和的成功哲學 A kinder, gentler philosophy of success


看完影片後,下次去超市看到冷凍食品,別再用先入為主的觀念看待啦!它們的營養含量遠比你想像的豐富許多呢!
