A lot of folks must appreciate the convenience of having already-washed and chopped salad greens sitting in the crisper. Bagged salad greens now make up a big part of most supermarket produce sections.

In reality, you're probably saving yourself no more than five minutes by buying these pricey bags. But to many, those five minutes make it a lot more likely that salad will be served.

"If time has been an obstacle keeping you from eating more salad, these bags of salad are a great answer," says Karen Collins, MS, RD, nutrition advisor to the American Institute for Cancer Research. "On the other hand, you do pay for this convenience."

Still, when you consider all the waste that occurs when you wash and trim a head of lettuce yourself, the extra cost is probably just a few cents.

The Healthiest Choices

So which bagged salad greens give you more bang for your three bucks?

In terms of phytochemicals and nutrients, the spinach and Romaine lettuce options are your best bets. Spinach in particular is a nutritional star; after all, it's a member of the acclaimed "dark leafy green" type of vegetables.

Carol Ann Brannon, MS, RD, a "food coach," author and speaker on functional foods, says she always buys a bag of spinach to mix in with other salad greens.

"Compared to other dark greens, spinach and kale have the highest antioxidant values," she notes.

Check out these numbers:

2 cups spinach leaves, chopped: 25 calories, 3 g fiber, 88 mg sodium; 94% Daily Value for vitamin A; 8% DV for vitamin B1; 16% for vitamin B2; 5% for vitamin B3; 14% for vitamin B6; 121% for folic acid; 52% for vitamin C; 24% for vitamin E; 14% for calcium; 32% for magnesium; 31% for potassium; 20% for iron.

2 cups Romaine lettuce, chopped: 18 calories, 1.5 g fiber, 9 mg sodium; 37% Daily Value for vitamin A; 10% DV for vitamin B1; 8% for vitamin B2; 4% for vitamin B3; 3%, for vitamin B6; 85% for folic acid; 45% for vitamin C; 6% for vitamin E; 5% for calcium; 8% for iron; 16% for potassium.

Serving and Storage Tips

The packages say "triple washed" and "ready-to-serve" but does that really mean you don't have to get out the colander and salad spinner? That's right, folks. The packagers wash the salad greens, so you don't have to. That's the beauty of the bag o' salad!

However, if you are buying the bag with three small heads of romaine lettuce in it, you may still need to rinse it well and pick out any older or browner pieces.

And how long do the bags of salad keep? Well, the first trick to buying them is buying the freshest bag in the store.

Check the "buy by" date stamped on the bag (usually in the upper right-hand corner), and the later the date, the better. Markets usually stock the newest bags in the back of the row, so try reaching back to the last few bags and checking their dates.

Keep the bags in the crisper, and they generally will keep for 3-5 days once opened. You'll know when you need to toss a bag because the greens will have brown areas and/or dry spots.

Embellishing Your Greens

Don't stop with salad greens. For taste and nutrition, try embellishing them with other convenient produce, like presliced carrots and prepared sugar snap peas (they usually come in small bags). Throw in some cherry or grape tomatoes and some sliced cucumber, and call it a salad!

For a supernutritious salad, Brannon suggests adding a bag of broccoli florets and/or shredded green or red cabbage to your greens. These cruciferous vegetables are rich sources of organosulfur and glucosinolates (groups of powerful anticancer phytochemicals).

You can also open a can of beans (red kidney, garbanzo, or black), rinse them, and sprinkle them over the top of your salad to give it a boost of protein and fiber.

Karen Collins, MS, RD, says a using a variety of different types of produce will provide a range of vitamins and phytochemicals to make your salads superhealthful (as well as interesting).

Fruits and nuts also make great additions to any green salad.

Brannon advises her clients to toss dried raisins or blueberries into their salads. Both are excellent sources of ellagic acid, an anticancer pytochemical.

"And raisins, blueberries, and blackberries have greater antioxidant power than other fruits," explains Brannon.

Nuts not only add a welcome crunch to your salad, they boost its nutrition and make it more satisfying.
