  • With the advent of freezers, we're able to keep our food lasting longer than ever before.

    自從冰箱冷凍庫被發明以來,比起過去,食物可以保存得更久。

  • But is there a difference between fresh and frozen produce in terms of nutrition?

    但新鮮食材與冷凍食品在營養價值上是否有所差異?

  • Which should you be eating?

    你該吃哪種?

  • Your instinct may be to shout out, "Of course fresh food is better!"

    你的直覺可能大喊:「新鮮食材當然比較好!」

  • "It's fresh!"

    「它是新鮮的!」

  • And you may be right, but it's highly dependent on the circumstances.

    你可能是對的,但別忘了其他條件也很重要。

  • 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.

    通常你在雜貨店架上拿下來的食物未成熟就採收,以免在運送途中受損。

  • This means it hasn't yet reached its peak nutrition.

    但這也表示它未達到營養巔峰。

  • Furthermore, the minute it was picked, its nutritional content began to deteriorate.

    此外,自採收的那刻起,它的營養開始流失。

  • The food is then loaded on a truck, boat or plane, travels for days, and waits on a shelf for you to choose it.

    接著被送上貨車、船、飛機,經過長期運輸、在架上等待你的挑選。

  • Afterwards, it may sit in your fridge for a few more days before being eaten.

    接著,它可能在冰箱放置數日。

  • Over this period of potentially weeks, the food may lose up to 50 percent of its nutritional value.

    長達數周後,食物可能流失高達 50% 的營養價值。

  • Frozen foods, on the other hand, are picked when they're ripe and frozen immediately.

    冷凍食品,另一方面,在成熟時開採並立即冷凍。

  • And while the quick freeze process does affect some of the vitamin content, it essentially freezes, or locks, most of the nutrients in place.

    迅速的冷凍過程,的確影響一些營養成分,它凍結、鎖住大部分的營養。

  • Next to the fresh produce that has been sitting around for weeks, there's no doubt that frozen foods can contain more nutrition.

    相較旁邊置放數週的「新鮮」食材,無庸置疑,冷凍食品含有更多營養。

  • Particularly during the month that local produce is not in season and traveling far distances.

    特別是非當季又經過長途運輸的食物。

  • 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.

    一系列研究發現,經過三天的保存,冷凍椰菜有更高含量的維他命 C、Beta 胡蘿蔔素,冷凍藍莓有更多的多酚和花青素,冷凍芽菜在所有營養檢測中分數較高。

  • 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.

    當然如果你從自家花園採摘蔬菜,或者從當地農夫市集取得並當天食用,營養及口感都無可匹敵。

  • But, unless you're able to shop every few days, frozen produce can be a great nutritionally comparable alternative.

    但除非你可以時常購物,冷凍食品相較之下,營養更佳。
