In that case, bags of frozen veggies are the most convenient option at the grocery store. But you may still be wondering if the frozen stuff is as nutritious as the fresh kind, and the answer—for the most part—is yes! The added bonuses of purchasing frozen vegetables are that they're available all year round, even if one particular veggie is not in season. According to Healthline, veggies are typically frozen right after they're harvested so they retain the majority of their nutrients. Bottom line, frozen bags of vegetable medleys and mixes are a great option for those who want to eat healthy without the risk of wasting any fresh produce.
