Cabbage, one of the oldest vegetables, continues to be a dietary staple and an inexpensive food. It is easy to grow, tolerates the cold, and keeps well. Cabbage is an excellent source of Vitamin C.

- Selection
Look for solid, heavy heads of cabbage. Avoid cabbage that has discolored veins or worm damage. Do not buy precut cabbage, the leaves may have already lost their vitamin C. Look for stems that are healthy looking, closely trimmed, and are not dry or split.
- Storage
Keep cabbage cold. This helps it retain its vitamin C content. Place the whole head of cabbage in a plastic bag and store in the refrigerator. Once the head has been cut, place the remainder in plastic bags and place it in the refrigerator. Try to use the remaining cabbage in the next day or two.
- Preparation
Do not wash cabbage until you are ready to use it. Avoid slicing or shredding cabbage in advance. This will cause it to lose some of its vitamin C content. If you must prepare it an hour or more in advance before cooking, place it in a plastic bag, seal tightly, and refrigerate.
- Varieties
There are at least a hundred different types of cabbage grown throughout the world, but the most common types in the United States are the Green, Red, and Savoy varieties. Chinese varieties are also available.
The two most common types of Chinese cabbage are Bok Choy and Napa cabbage. Chinese cabbage cooks in less time than standard U.S. types, but can be prepared in the same ways. Cabbage can be steamed, boiled, braised, microwaved, stuffed, or stir-fried.
