You seem to already be a smart shopper, but since canned can really save you, I'll add my 2 cents. Another reason to have canned veggies and fruit on hand is it's good to have food that won't spoil if you don't have electricity. I believe in buying ahead to be prepared should you have an emergency (financial, natural disaster, or illness). Think of so many hurricane evacuees complaining of being hungry and expecting the govt to have food ready for all of them. What if they'd cleaned out the cupboards of canned foods? We live in an area that has to watch hurricanes and just moved from Orange, TX (got the eye of Rita), so you better believe I used canned products. But I digress. You can disguise canned veggies in casseroles. I've baked with canned peaches. The other way canned can really save is that fresh has a much shorter shelf life which means more frequent grocery trips at $3/gal.

A recent study conducted by the University of Massachusetts found that recipes using canned ingredients are similar in nutritional values and taste appeal to those made with fresh or frozen items. The research analyzed nutritional content of entire recipes comparing such nutrients as protein, carbohydrates, vitamins and minerals. The study also conducted sensory analysis evaluating taste, appearance, color, aroma and texture of dishes prepared with canned, fresh and/or frozen ingredients. . . .
It was the third and most complex nutrition study yet to test canned foods vs. fresh and frozen counterparts. ...
"Our research found similar nutrient profiles of dishes made from canned, fresh and/or frozen ingredients," Samonds said. "In fact, recipes made with canned ingredients are good sources of many nutrients, like their fresh and frozen counterparts. Our results also showed that recipes prepared with canned foods delivered favorably on taste, appearance, aroma and texture."
According to Samonds, key findings from the nutrition study included:
Nutritional analysis of 13 "family-friendly" recipes found similar nutrient content of dishes made with canned, fresh and/or frozen ingredients. In the test, UMass researchers compared protein, carbohydrates, vitamins and minerals in each dish. For example, the Tuna Salad Wrap recipe, which included white tuna, pita bread, celery, chopped apples and mango one with canned ingredients and one with fresh ingredients proved to be an excellent source of protein, niacin, vitamin B-12 and riboflavin, regardless of the ingredient form.
And sensory findings showed that 10 of the 13 recipes prepared with canned ingredients were equally or more acceptable in taste, appearance, aroma and texture than those prepared with fresh and/or frozen ingredients.
"This study shows that the ingredients you choose, not the form of the ingredients, are what really determine a recipe's nutrient content," Samonds said. "With limited growing seasons in most of the country, canned food provides an ideal way to add nutrition, flavor and variety to any recipe, anywhere and at any time of the year."
