Frozen vegetables are just as healthy as fresh, and they're less expensive.
According to a recent USDA study, a pound of fresh broccoli is about 70 cents more expensive than frozen. There is very little loss of nutrients such as vitamins C and B during the freezing process of vegetables.
A recent paper in the Journal of the Science of Food and Agriculture found that frozen foods lose only a small amount of nutrients. There is also very little nutrient loss in the freezer.
Frozen vegetables also keep longer, resulting in less waste.
