Arugula
Also indexed as: Rocket Greens, Roquette, Rucola
The slender leaves of arugula offer a peppery, pungent flavor.
Pronounced “ah-roo-guh-lah,” this deep green vegetable with long,
slender leaves has an illustrious history in Italian cooking. Also called rocket, roquette,
and rucola, arugula is peppery and aromatic, with a pungent, somewhat bitter flavor.
Varieties
Arugula varies somewhat in size.
Buying and storing tips
Arugula can be found in the produce section of most health food stores, specialty markets,
and supermarkets. It’s usually sold in small bunches, with the roots intact. Look for
bright green, fresh-looking leaves with no sign of wilting or browning, and fresh clean roots.
Store arugula in a plastic bag in the refrigerator, and use it within a couple of days.
Availability
Arugula is available all year long, and is at its peak from June through December.
Preparation, uses, and tips
Wash arugula leaves thoroughly, immersing them completely in cold water to remove grit. Pat
dry, or spin dry in a salad spinner. Toss fresh arugula with salad greens, or add to most
soups and stews near the end of cooking time.

Health benefits and concerns
Cancer
The strong association between increased intake of
beta-carotene from food and a reduced risk of lung
cancer does not necessarily mean that supplementation with natural beta-carotene
supplements would reduce the risk of lung cancer. Dietary beta-carotene may be a marker for
diets high in certain fruits and vegetables that contain other anticancer substances that
may be responsible for the protective effects. Until more is known, some doctors advise
smokers to avoid all forms of beta-carotene supplementation—even natural
beta-carotene.
Cataracts
Some, but not all, studies have reported that eating more foods rich in beta-carotene or vitamin A was associated with a lower risk of cataracts.
Synthetic beta-carotene supplementation has not been found to reduce the risk of cataract
formation. It remains unclear whether natural beta-carotene from food or supplements would
protect the eye or whether beta-carotene in food is merely a marker for other protective
factors in fruits and vegetables high in beta-carotene.
High
Homocysteine
A controlled trial showed that eating a diet high in fruits and vegetables containing folic acid, beta-carotene, and vitamin C effectively lowered homocysteine levels. Healthy people
were assigned to either a diet containing a pound of fruits and vegetables per day, or to a
diet containing 3 1/2 ounces (99g) of fruits and vegetables per day. After four weeks, those
eating the higher amount of fruits and vegetables had an 11 percent lower homocysteine level
compared to those eating the lower amount of fruits and vegetables.
Macular
Degeneration
People who eat plenty of fruits and vegetables high in beta-carotene appear to be at lower
risk for macular degeneration than people who do not eat these foods. However, another study
found no association between age-related macular degeneration and intake of antioxidants,
either from the diet, from supplements, or from both combined. More research is needed to
reconcile these differences. In the meantime, beta-carotene-rich vegetables continue to be
part of a healthful diet.
