The herb is rich in many vitamins, particularly vitamin K, which is needed for blood clotting and bone health (4Trusted Source).

Parsley is also a great source of vitamins A and C — important nutrients with antioxidant properties (5Trusted Source).

Additionally, it’s very low in calories yet packed with flavor, making it a great low-calorie ingredient for many recipes.

Summary Parsley is a low-calorie, nutrient-dense
herb. It’s particularly rich in vitamins K, A, and C.

Parsley contains many powerful antioxidants that can benefit your health.

Antioxidants are compounds that prevent cellular damage from molecules called free radicals. Your body requires a healthy balance of antioxidants and free radicals to maintain optimal health (6Trusted Source).

The main antioxidants in parsley are (7Trusted Source, 8Trusted Source, 9):

• flavonoids
• carotenoids
• vitamin C

The fragrant herb is particularly rich in a class of antioxidants known as flavonoids. The two main flavonoids include myricetin and apigenin.

Studies show that diets rich in flavonoids may lower your risk of conditions, including colon cancer, type 2 diabetes, and heart disease (10Trusted Source, 11Trusted Source, 12Trusted Source).

Furthermore, beta carotene and lutein are two antioxidants known as carotenoids. Many studies associate higher intake of carotenoids with a reduced risk of certain diseases, including lung cancer (13Trusted Source).

Vitamin C also has strong antioxidant effects and plays an important role in supporting immune health and protecting against chronic disease (14Trusted Source).

Interestingly, dried parsley may be higher in antioxidants than fresh sprigs. In fact, one study found that the dried herb had 17 times more antioxidant content than its fresh counterpart (7Trusted Source).

Summary Parsley contains many
powerful antioxidants, which may help prevent cell damage and lower your risk
of certain diseases.

Your bones need certain vitamins and minerals in varying amounts to remain healthy and strong.

Parsley is packed with vitamin K — an essential nutrient for bone health. A 1/2 cup (30 grams) provides an impressive 547% of the RDI (3Trusted Source).

Vitamin K helps build stronger bones by supporting bone-building cells called osteoblasts. This vitamin also activates certain proteins that increase bone mineral density — a measure of the amount of minerals present in your bones (15Trusted Source).

Bone density is important, as a lower bone mineral density is associated with an increased risk of fractures — especially in older adults (16Trusted Source).

Some studies suggest that eating foods high in vitamin K may reduce your risk of fractures. One study found that higher vitamin K intake was associated with a 22% lower risk of fractures (17Trusted Source, 18Trusted Source).

Typical dietary intakes of vitamin K may be below the levels needed to improve bone mineral density and reduce fracture risk. Therefore, eating foods like parsley may benefit bone health (19Trusted Source).

Summary Parsley is rich in vitamin
K, which is an essential nutrient for optimal bone health. Eating foods high in
this nutrient has been linked to a reduced risk of fractures and improved bone
mineral density.

Parsley contains plant compounds that may have anticancer effects.

Oxidative stress — a condition characterized by an imbalance in levels of antioxidants and free radicals — is associated with the development of certain chronic diseases, including cancer (7Trusted Source, 20Trusted Source).

Parsley is particularly rich in flavonoid antioxidants and vitamin C, which reduce oxidative stress in your body and may lower your risk of certain cancers.

For example, high dietary intake of flavonoids may reduce colon cancer risk by up to a 30% (21Trusted Source).

Additionally, subgroups of certain flavonoids in parsley — such as myricetin and apigenin — have shown anticancer activity in test-tube and animal studies (22Trusted Source, 23Trusted Source).

Plus, eating foods rich in vitamin C may reduce your risk of cancer as well. A 1/2 cup (30 grams) of parsley provides 53% of the RDI for this nutrient.

One study found that increasing vitamin C by 100 mg per day reduced the risk of overall cancer by 7%. Moreover, increasing dietary vitamin C by 150 mg per day may lower prostate cancer risk by up to 21% (24Trusted Source, 25Trusted Source)

Summary Parsley contains various
antioxidants — like flavonoids and vitamin C — that may provide cancer-fighting
benefits.

Lutein, beta carotene, and zeaxanthin are three carotenoids in parsley that help protect your eyes and promote healthy vision. Carotenoids are pigments found in plants that have powerful antioxidant activity (26Trusted Source, 27Trusted Source).

Lutein and zeaxanthin may prevent age-related macular degeneration (AMD), an incurable eye disease and a leading cause of blindness around the world.

In fact, eating foods rich in lutein and zeaxanthin may reduce your risk of late AMD by up to 26% (28Trusted Source, 29Trusted Source, 30Trusted Source).

beta carotene is another carotenoid that supports eye health. This carotenoid can be converted into vitamin A in your body (31Trusted Source).

This conversion of beta carotene explains why parsley is very rich in vitamin A. A 1/2 cup (30 grams) of freshly chopped leaves provides 108% of the RDI for this vitamin (3Trusted Source).

Vitamin A is essential for eye health, as it helps protect the cornea — the outermost layer of your eye — as well as the conjunctiva — the thin membrane covering the front of your eye and the inside of your eyelids (32Trusted Source).

Summary

Parsley contains lutein, zeaxanthin, and beta carotene, plant compounds that protect eye health and may reduce your risk of certain age-related eye conditions like AMD.

Parsley is a nutrient-dense herb that may improve heart health. For example, it’s a good source of the B vitamin folate — with 1/2 cup (30 grams) providing 11% of the RDI (3Trusted Source).

High intakes of dietary folate may reduce heart disease risk in certain populations. A large study in over 58,000 people found that the highest intake of folate was associated with a 38% reduced risk of heart disease (33Trusted Source).

Conversely, low intake of folate may increase your risk of heart disease. One study in 1,980 men observed a 55% increase in heart disease risk in those with the lowest intake of this nutrient (34Trusted Source).

Some experts hypothesize that folate benefits heart health by lowering levels of the amino acid homocysteine. High homocysteine levels have been linked to a higher risk of heart disease in some studies.

Homocysteine may negatively affect heart health by altering the structure and function of your arteries. However, the connection between this amino acid and heart disease still remains controversial (35Trusted Source, 36Trusted Source).

Summary Parsley is rich in
folate, a B vitamin that protects your heart and may reduce your risk of heart
disease.

Parsley may have antibacterial benefits when used as an extract.

For example, a test-tube study demonstrated that the extract showed significant antibacterial activity against yeast, molds, and a common, infection-causing bacteria known as S. aureus (37Trusted Source, 38Trusted Source).

The extract may also prevent the growth of bacteria in food. Another test-tube study found it prevented the growth of potentially harmful bacteria, such as Listeria and Salmonella — both known to cause food poisoning (39Trusted Source, 40Trusted Source, 41Trusted Source).

Though the extract shows antibacterial potential in test-tube studies, these benefits have not yet been studied in humans.

Summary Parsley extract has been
shown to have antibacterial properties in test-tube studies. Still, more
research is needed.

Parsley is an extremely versatile and inexpensive flavoring option.

You can use the dried version as an ingredient in various recipes. It can enhance the flavor of soups, stews, and tomato sauces. Additionally, it’s often combined with other herbs in Italian-inspired recipes.

Fresh parsley is also a great addition to homemade salad dressings, marinades, and seafood recipes. Many people use fresh sprigs in recipes that don’t require cooking or add the herb at the end of the cooking period.

Here are a few more ways to add parsley to your diet:

• Stir fresh
  leaves into a homemade chimichurri sauce.
• Mix finely chopped leaves into
  your salad dressings.
• Sprinkle fresh or dried leaves on
  top of a salmon dish.
• Finely chop the stems and add to a
  potato salad for an extra crunch.
• Simmer dried
  flakes in a homemade tomato sauce.

Interestingly, the herb may act as a natural breath freshener, so you can also chew on a sprig while cooking to freshen up your breath (42Trusted Source).

To extend the life of fresh parsley, wrap the bunch in a damp paper towel and store it in a closed container in the refrigerator.

Summary Parsley can be used as a
dried spice or fresh herb. Dried flakes are usually added to hot dishes like
soup and pasta, while the fresh herb is a great addition to salads and
dressings.

Parsley is a versatile herb that provides a concentrated source of nutrients. It’s particularly rich in vitamins A, C, and K.

The vitamins and beneficial plant compounds in parsley may improve bone health, protect against chronic diseases, and provide antioxidant benefits.

You can incorporate dried or fresh leaves easily into your diet by adding them to soups, salads, marinades, and sauces.
