This article provides a complete overview of mustard greens, including their nutritional value, benefits, and potential harm.

Nutritional value, composition and calorie content

Mustard greens are one of the most nutrient-dense foods you can eat because they are low in calories yet rich in fiber and micronutrients ().

One bowl (55 gram serving) of chopped raw mustard greens contains ():

  • Calories : 15 kcal
  • Protein : 2 grams
  • Fat : less than 1 gram
  • Carbohydrates : 3 grams
  • Fiber : 2 grams
  • Sugar : 1 gram
  • Vitamin A : 9% of recommended daily intake (RDI)
  • Vitamin B6 (pyridoxine) : 6% of RDI
  • Vitamin C : 44% of RDI
  • Vitamin E : 8% of RDI
  • Vitamin K : 120% of RDI
  • Copper : 10% of RDI

In addition, mustard greens contain 4–5% of the RDA for calcium, iron, potassium, riboflavin (vitamin B2), magnesium and thiamine (vitamin B1), as well as small amounts of zinc, selenium, phosphorus, niacin (vitamin B3) and folate ( ).

Compared to raw mustard greens, one bowl (140 grams) of cooked mustard greens has much higher levels of vitamin A (96% of the RDI), vitamin K (690% of the RDI), and copper (22.7% of the RDI). However, it contains less vitamins C and E ().

Pickled mustard greens, often called takana in Japanese and Chinese cuisine, are similar in calories, carbohydrates and fiber to raw mustard. But it loses some nutrients during pickling, especially vitamin C ().

However, one study found that pickling was an effective method for preserving important plant compounds with antioxidant properties ().

Summary:

Mustard greens are low in calories but high in fiber and many essential vitamins and minerals. In particular, it is an excellent source of vitamins C and K.

Mustard seasoning

Mustard products are made from the seeds of the plant. They have a pungent taste and benefit the body due to their chemical composition. Spices are rich in organic acids, vitamins, essential oils, and fatty acids.

What are the benefits of mustard greens?

There is currently limited research into the specific health benefits of mustard greens.

However, individual nutrients found in mustard greens—and brassicas in general—have been linked to numerous health benefits.

Rich in disease-fighting antioxidants

Antioxidants are natural plant compounds that help protect against oxidative stress caused by excess free radicals ().

Free radicals are unstable molecules that can damage your cells. Research shows that over time, this damage can lead to serious chronic diseases such as heart disease, cancer, and Alzheimer's disease (,).

While levels of specific antioxidants vary among mustard green varieties, this leafy green vegetable in general is a rich source of antioxidants such as flavonoids, beta-carotene, lutein, and vitamins C and E (, , , ).

Additionally, red varieties are rich in anthocyanins, which are red-purple pigments found in fruits and vegetables and are associated with a reduced risk of heart disease, cancer, and type 2 diabetes (,).

Overall, including mustard greens in your diet may help protect against oxidative stress-related diseases.

Excellent source of vitamin K

Both raw and cooked mustard greens are a phenomenal source of vitamin K, providing 120% and 690% of the RDA per serving (55 grams and 140 grams), respectively (, ).

Vitamin K is best known for its vital role in blood clotting. It has also been shown to be important for heart and bone health ().

In fact, vitamin K deficiency has been linked to an increased risk of heart disease and osteoporosis, a condition that leads to decreased bone strength and an increased risk of fractures (, ).

Recent studies have also shown a link between vitamin K deficiency and brain health. Insufficient vitamin K levels may be associated with an increased risk of brain damage, dementia and Alzheimer's disease. However, more research is needed (,).

May boost immunity

Mustard greens may also be beneficial for your immune system.

Just one bowl of mustard (55 grams raw, 140 grams cooked) provides your body with more than a third of your daily vitamin C needs (,).

Vitamin C is a water-soluble vitamin essential for strengthening the immune system. Research shows that not enough vitamin C in your diet can weaken your immune system and make you more susceptible to disease ().

Additionally, the vitamin A found in mustard greens also supports your immune response. It does this by stimulating the growth and proliferation of T cells, which are a type of white blood cell needed to fight potential infections (,).

May Benefit Heart Health

Mustard greens may also be good for your heart.

It is rich in antioxidants, such as flavonoids and beta-carotene, which are associated with a reduced risk of developing and dying from heart disease (, , ).

One review of eight studies found that a high intake of leafy green vegetables, the brassica family, was associated with a significant 15% reduction in the risk of heart disease ().

Like other vegetables in the cabbage family, mustard contains substances that help bind bile acids in your digestive system. This is important because preventing the reabsorption of bile acids leads to lower cholesterol levels ().

According to one test-tube study, steaming mustard greens significantly enhances the bile acid binding effect. This suggests that steamed mustard greens may have greater cholesterol-lowering potential compared to eating them raw ().

May be good for eye health

Mustard greens also contain antioxidants like lutein and zeaxanthin, which have been shown to be beneficial for eye health (, , , ).

Specifically, these two compounds help protect the retina from oxidative damage and also filter out potentially harmful blue light (, ).

As a result, research suggests that eating foods rich in lutein and zeaxanthin may help protect against age-related macular degeneration, which is the leading cause of blindness worldwide ().

May have anti-cancer properties

In addition to powerful antioxidants that may have antitumor effects, mustard greens are high in beneficial plant compounds called glucosinolates ().

In test-tube studies, glucosinolates have been found to help protect cells from DNA damage and prevent the growth of cancer cells. However, these beneficial properties have not been studied in humans ().

Similarly, a test-tube study of mustard leaf extract found protective effects against colon and lung cancer. However, human studies are needed ().

In terms of human studies, observational studies have shown an association between overall consumption of cabbage vegetables—but not mustard greens in particular—and a reduced risk of certain types of cancer, including stomach, colorectal, and ovarian cancer (, , , ).

Summary:

Mustard greens are rich in important plant compounds and micronutrients, particularly vitamins A, C, and K. As a result, eating them may be beneficial for eye and heart health, and may also reduce the risk of cancer and boost the immune system.

Potential harm and contraindications

Although research is limited, mustard greens are generally considered very healthy and safe. However, it may cause side effects in some people.

Because mustard greens are rich in vitamin K—a vitamin that helps with blood clotting—eating them may interact with blood-thinning medications.

Therefore, people who are taking blood thinners should consult their doctor before including large amounts of these green leaves in their diet.

Additionally, mustard greens contain oxalates, which may increase the risk of kidney stones in some people if consumed in large quantities. If you are prone to the oxalate type of kidney stones, you may want to limit the amount of mustard in your diet ().

Summary:

Mustard greens are generally very safe to eat. However, because it is rich in vitamin K and contains oxalates, large amounts may cause side effects in people who take blood thinners or have a high risk of developing oxalate-type kidney stones.
