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.
