Frozen foods are high in sodium.

Because the freezing itself is a preservative, additives, such as sodium, are not necessarily needed to keep the food edible for a longer shelf life. Many frozen bags of fruits and vegetables will not include any added salt; however, if you are buying frozen pre-made dinners and meals, you may discover a high sodium content. For this reason, it’s important to know how to read nutrition labels and make healthy choices based on what you see on the label.
