Fresh (meaning raw) vegetables are, generally, preferred over cooked or canned vegetables, in regards to nutrition. The cooking process itself (boiling, steaming, frying, baking, etc.) tends to remove some of the nutrients from the food. The canning process requires that food be heated, along with their containers, to a level high enough to sterilize them before being sealed. That heating converts some of the more delicate nutrients to other compounds. The most obvious example, for spinach, is Vitamin K. Vitamin K is an essential nutrient used by the body in coagulating the blood. It helps to prevent bruising and bleeding. In a cup of raw spinach there is about 145 mcg (micrograms) of Vitamin K. That's 181% of the RDA (recommended daily allowance). In cooked/canned spinach that number drops to less than 2%. See what I mean?
