Dill (Anethum graveolens) is an herb thats found throughout European and Asian cuisines (1).

Also called dill weed, the plant has slender stems with alternating soft leaves and brown, flat, oval seeds. While the leaves have a sweet, grassy flavor, dill seeds are more aromatic, with a slight citrus flavor thats similar to caraway seeds.

As herb and spice, dill is commonly used to elevate the flavor of various dishes. Its often paired with salmon, potatoes, and yogurt-based sauces.

In addition to culinary uses, dill is rich in several nutrients and has traditionally been used to treat various ailments, including digestive issues, colic in infants, and bad breath (1).

This article reviews the nutritional and health benefits of dill, as well as ways to use it in cooking.

One cup (9 grams) of fresh dill sprigs provides approximately (2):

Fresh dill is very low in calories, yet a surprisingly good source of several essential vitamins and minerals, including vitamin C, manganese, and vitamin A (2).

Vitamin A is an essential nutrient that is important for maintaining vision and supporting a healthy immune system. It also plays a role in male and female reproduction (3, 4).

Similarly, vitamin C is vital for your immune system and helps with bone formation, wound healing, and metabolism (5, 6).

Additionally, it has been shown to be a potent antioxidant that helps protect your cells against damage caused by unstable molecules known as free radicals (6, 7).

Dill is also a good source of manganese. While needed in very small amounts, it is an essential mineral that supports normal functioning of your brain, nervous system, and metabolism of sugar and fat (8).

Furthermore, fresh dill provides 12% of the DV for calcium, copper, magnesium, potassium, riboflavin, and zinc (2).

However, as fresh dill is usually consumed in smaller quantities than 1 cup (9 grams), the amount of nutrients you get from sprinkling it over your food will be considerably less.

As for dill seeds, they have many similar nutritional benefits. One tablespoon (6.6 grams) of seeds provides 8% of the DV for calcium, 6% of the DV for iron, and 15% of the DV for magnesium, manganese, phosphorus, and potassium (9).

Fresh dill is low in calories, yet a good source of many essential nutrients, including vitamin C, magnesium, and vitamin A.

With its name derived from the Old Norse word dilla, which means to soothe, dill has been used since ancient times to treat colic in infants and digestive diseases, as well as to help with breastfeeding (10).

While these more traditional uses have not been supported by research, dill has been shown to have other potential health benefits.

Antioxidants are naturally occurring compounds that help protect cells against damage caused by unstable molecules known as free radicals (11).

As a result, research suggests that consuming foods rich in antioxidants may help reduce chronic inflammation and prevent or even treat certain conditions, including heart disease, Alzheimers, rheumatoid arthritis, and certain forms of cancer (11, 12)

Both the seeds and leaves of the dill plant have been found to be rich in several plant compounds with antioxidant properties, including (1, 13):

Additionally, dill is a good source of vitamin C, which has also been shown to have powerful antioxidant properties (6, 7).

Heart disease is the leading cause of death worldwide. However, the World Health Organization estimates that nearly 75% of heart disease cases could be prevented by reducing risk factors like poor diet, smoking, and lack of exercise (19, 20).

Additional risk factors for heart disease include elevated blood pressure, triglyceride, and LDL (bad) cholesterol levels, as well as chronic inflammation (21, 22).

Flavonoids, like those found in dill, have been shown to protect heart health due to their potent antioxidant and anti-inflammatory properties (23).

Furthermore, animal studies have suggested that dill extract may have cholesterol- and triglyceride-lowering effects. However, research in humans in more mixed (10, 24).

One study in 91 people with high total cholesterol and triglyceride levels found that taking 6 dill extract tablets daily for 2 months significantly improved total cholesterol and triglyceride levels but did not change HDL (good) cholesterol levels (25).

Yet, another study in 150 people with high cholesterol and triglyceride levels observed no significant changes in cholesterol or triglyceride levels after 6 weeks of daily dill tablet intake (26).

However, its important to note that most studies looking at the effects of dill on heart health have used extracts. As a result, its unclear how fresh or dried dill in your diet could affect heart health.

Overall, while the antioxidants in dill extracts may benefit overall heart health, more studies in humans are needed to assess the effectiveness of dill on cholesterol and triglyceride levels.

Having chronically high blood sugar levels is concerning as they can increase your risk of conditions like insulin resistance, metabolic syndrome, and type 2 diabetes (27).

Dill has been suggested to have blood-sugar-lowering effects (10).

In fact, several studies in animals with diabetes have shown a significant improvement in fasting blood sugar levels with daily doses of dill extract. Still, research in humans is limited (10, 28).

Monoterpenes are a class of terpenes, which are naturally occurring plant compounds that are linked to anticancer, antiviral, antifungal, and anti-inflammatory properties (1, 29).

Theyre commonly found in essential oils of plants like dill and have been associated with anticancer properties (1).

More specifically, d-limonene is a type of monoterpene that studies have shown may help prevent and treat lung, breast, and colon cancer (30, 31, 32).

As dill is high in monoterpenes, particularly d-limonene, it may have anticancer properties. However, theres currently no research on the effectiveness of dill or dill extract on the risk or treatment of cancer.

Dill may benefit your health in the following ways as well:

Dill is rich in a variety of plant compounds that may have numerous benefits for health, including protection against heart disease and certain forms of cancer. Additionally, dill may help lower blood sugar levels, but more human studies are needed.

Dill is generally safe for consumption. However, in rare cases it has been shown to cause allergic reactions, vomiting, diarrhea, an itchy mouth, swollen red bumps on the tongue, and throat swelling (10).

Additionally, its recommended to avoid dill pills or extracts during pregnancy and breastfeeding as theres limited research of their safety.

Culinary uses of dill are considered safe for most individuals, except in rare cases when it could trigger an allergic response. Additionally, women who are pregnant or breastfeeding are recommended to avoid dill pills or extracts.

Dill is a flavorful ingredient thats easy to add to your food.

Here are some ways to add fresh dill to your meals:

Dried dill can also be used to add flavor to dips, marinades, and potato, chicken, or tuna salads.

As for the seeds, dill seeds can be used whole or crushed and added to bread, soups, or vegetable dishes. They can also be used to make dill pickles.

Dill is a versatile herb that can be used in a variety of dishes, such as in a potato salad, tzatziki sauce, or over fish. Dill seeds can be used as a spice to flavor foods like pickles or bread.

To store fresh dill, you first want to lightly spritz the leaves with fresh water, wrap the sprigs loosely in a paper towel, and then place them in a zip-top plastic bag.

Store the dill in the vegetable drawer of your fridge for up to 1 week. For longer storage, you can also freeze fresh dill by rinsing and then placing the sprigs in a single layer on a cookie sheet in the freezer.

Once frozen, transfer the sprigs to a freezer-safe bag and return to the freezer for up to 6 months for best flavor.

Frozen dill can be used in cooking without thawing first. Dried dill and dill seeds should be stored in an airtight container in a cool, dark place for 6 months to 1 year (39).

When stored properly, fresh dill will keep for up to 1 week in the fridge and up to 6 months in the freezer. Dried dill and dill seeds should keep for 6 months to 1 year.

Rich in antioxidants and a good source of vitamin C, magnesium, and vitamin A, dill may have several benefits for health, including protection against heart disease and cancer.

However, its important to keep in mind that most studies looking at the benefits of dill use dill extracts. Therefore, its unclear whether dietary use of fresh or dried dill would have the same effects.

In any case, both the seeds and leaves of dill can add flavor and a pop of color to a variety of dishes. When stored properly, fresh dill can keep for up to 1 week in the fridge and several months in the freezer.

Overall, dill is a flavorful herb and spice that can add a nutritional boost to your diet.
