Artichokes are commonly eaten steamed, boiled, braised or fried, but raw artichokes can actually be a simple way of preparing these delicious and nutrient-rich vegetables. Artichokes naturally contain antioxidants, such as flavonoids, which, along with certain vitamins, such as vitamin C, are heat-sensitive. Thus, eating raw artichokes might be the best way for you to get the most nutritional value possible.

According to Mark Bittman, columnist for "The New York Times" and author of “How To Cook Everything Vegetarian,” the most important factor in choosing an artichoke that you plan on eating raw is freshness. Otherwise, the variety doesn’t matter, although young artichokes will have more tender leaves, which can make them easier to prepare and to eat.

You can use the heart for raw salads, or you can eat the artichoke as you would a steamed one -- whole, leaf-by-leaf, followed by the heart and stem. To eat a whole raw artichoke, remove the leaves individually and scrape with your teeth to remove the leaf. When you reach the heart, you need to remove the choke -- the prickly part at the center. You remove it by cutting away at the base, although sometimes you can simply spoon it out. You can then eat the heart and stem as is. For a raw artichoke salad, use only the heart, sliced into thin pieces and dressed with lemon juice to prevent browning. You can keep some of the leaves for a garnish, or eat them on their own as a tasty snack.

A single, medium-sized globe artichoke has only 60 calories per serving and minimal amounts of fat. It is also a rich source of a number of essential minerals and vitamins, particularly potassium and phosphorus. It contains 9.6 to 16 percent of the recommended dietary intake of phosphorus and 10 percent of the recommended dietary intake of potassium per serving. Phosphorus helps your body build strong bones and teeth, while potassium is needed to regulate your heart’s electrical activity, build muscle and maintain your body’s acid-base balance. Raw artichokes are also a good source of vitamin C, providing between 12.5 and 20 percent of the daily dietary intake for adults. Vitamin C is used to make collagen, an essential protein for healthy skin, tendons, ligaments and blood vessels.

Raw artichokes are naturally high in dietary fiber, which can help prevent overeating as it makes you feel fuller faster. A single medium artichoke has 6.9 grams of dietary fiber, which is between 18 and 27.6 percent of your daily recommended intake. This percentage is especially high given the relatively small serving size of a single artichoke. A diet high in dietary fiber is also important for maintaining good colon and digestive system health, as it can prevent constipation, hemorrhoids or diverticulosis. Dietary fiber has also been shown to help reduce blood cholesterol levels.
