Hi! I'm Elena, your nutrition expert from Castelló, and today we're going to answer a question I hear all the time at the market: Are frozen vegetables worth choosing, or are they "worse" than fresh ones?
This morning, while organizing my freezer in Novelda, I was thinking about how convenient these bags are: they're already washed, chopped, and ready to use. But beyond convenience, they're technically a top-tier nutritional tool. There's a myth that they "lose vitamins", but the science will surprise you.
Do they have fewer vitamins than fresh ones?
The short answer is: not necessarily. In fact, in many cases, they can be superior!
-
The ideal timing: Frozen vegetables are harvested at their peak ripeness, in season, and flash-frozen within hours.
-
Fresh doesn't always mean "just picked": A fresh vegetable can spend days in trucks, warehouses, and on shelves, losing vitamins along the way.
-
Blanching: Before freezing, they undergo a quick blanching process to eliminate microorganisms and stop enzymes. Although a small amount of vitamin C and B is lost, this loss is usually less than what a fresh vegetable suffers after a week in your fridge.
How to choose and cook them like a pro
To keep all their texture and nutritional value, follow these technical tips:
-
At the supermarket: Feel the package. The vegetables should be loose. If the package is a solid block with frost, it means the cold chain has been broken, the water has seeped out, and it has refrozen. That vegetable will have lost texture and nutrients.
-
The shopping: Put the frozen bags in your cart last and always take them home in insulated bags.
-
Cooking: As a general rule, don't thaw them. Put them straight into boiling water. Use little water to minimize vitamin loss and, of course, make use of that broth for rice or a stew.
Tools from my Pantry
Natural frozen vegetables are fantastic, but be careful with ready-made "stir-fries" that come with sauces, as they often have too much salt and low-quality fats. For your natural vegetables, I use these basics:
-
Healthy Hydration: Pair your vegetable dish with our Lemon Iced Tea.
Elena's "Life Tip"
Home Freezing vs. Industrial: Remember that your home freezer works at -18 °C (slow freezing), which creates large ice crystals that break the vegetable's fibers. Industry uses flash freezing (microscopic crystals). That's why, if you're going to take a while to use a fresh vegetable, it's better to buy it already factory-frozen; it will keep the "al dente" texture we all love much better.
Do you always keep a "staple" supply of vegetables in the freezer for quick dinners, or do you prefer to go to the market every day? Tell me your tricks for eating green every day!
