One thing you don’t have to worry about is whether your frozen corn has fewer vitamins and minerals than fresh corn: Fruits and vegetables are frozen at their peak ripeness, which preserves their nutritional content. That means that the freezing process can help retain essential vitamins and minerals. If your fresh ears of corn have been in the fridge for a while, your frozen corn is likely more nutritious. Same goes for strawberries, green beans, broccoli, carrots, pineapple, and your other favorite fruits and veggies.
