It depends on which ones you buy, some of them are super high in sodium and corn syrup or just mainly starches, highly processed and with not enough vegetables to make it count.

Stay informed about the potential risks of relying on frozen meals. Learn about excessive sodium, sugar, and other risks to your health.
