You can find nutrition info online, I'm sure. I know that by cooking from scratch, I'm avoiding a lot of preservatives and salt in my food. Some preservatives will actually block your body's ability to absorb vitamins and other nutrients if eaten over an extended period of time.
Actually, I know that there are websites that will give you the nutional info that goes along with the recipes, the website I got my chicken noodle soup recipe from does that.
