But is there a difference between fresh and frozen produce in terms of nutrition? Which should you be eating?

但新鮮食材與冷凍食品在營養價值上是否有所差異？你該吃哪種呢？

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.

你的直覺可能大喊：「新鮮食材當然比較好！它是新鮮的！」 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, this means it hasn't yet reached its peak nutrition.

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

冷凍食品，另一方面，在成熟時開採並立即冷凍，迅速的冷凍過程的確會影響一些營養成分，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, particularly during the month that local produce is not in season and traveling far distances.

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，特別是跟非當季又經過長途運輸的食物相比。

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。
