Do veggies lose nutrients when frozen?

No, frozen vegetables generally do not lose significant nutrients; in many cases, they retain as many or even more vitamins and minerals than "fresh" produce that has spent time in transit and on shelves, because they are flash-frozen at peak ripeness, locking in nutrients. While some slight losses of water-soluble vitamins (like C) can occur during blanching before freezing, freezing itself preserves most nutrients, making them a healthy, convenient, and often more budget-friendly choice.

Are frozen vegetables still nutritious?
