However, many people have been using the plant’s green leaves for their health benefits and cooking purposes for ages. As the name suggests, mustard greens are leaves from the mustard plant. They have multiple uses, including antiseptic & disinfection for wound healing, supporting renal function with a diuretic, detoxifying and strengthening agent for the blood and a cold and sore throat therapy.

While studies don’t recognise all of the greens’ traditional usage, they imply that they have a variety of health benefits. Mustard greens have a significant flavour, and people use them to lend a bitter, peppery flavour to any dish. Some ways to use them are in raw form, boiling, steamed, or stir-fried.

Benefits of Consuming Mustard Greens

Rich in Antioxidants

Antioxidants are plant chemicals that defend against oxidative stress caused by an overabundance of free radicals. Free radicals are highly active chemicals that can pose a threat to your cells. According to research, free radicals can lead to significant chronic illnesses, including cardiovascular disease, cancer, and Alzheimer’s disease, over time. Mustard greens are high in antioxidants such as flavonoids, lutein and vitamin C. These antioxidants help combat free radical damage and prevent various chronic diseases.

Loaded with Vitamin K

Mustard greens, both raw and cooked, are an excellent source of vitamin K. Vitamin K is widely known for its role in preventing blood clotting. It’s also proven to be very beneficial to the heart and bones.

Vitamin K deficiency is related to an increased risk of cardiovascular disease and osteoporosis, a condition characterised by weakened bones and a higher risk of fractures. Furthermore, recent studies prove the importance of vitamin K for brain health. Vitamin K deficiency can lead to a higher risk of cognitive impairment, dementia, and Alzheimer’s disease.

Potential Immunity Booster

Mustard greens can be beneficial to your immune system. It is because mustard greens contain high amounts of vitamin C, a water-soluble vitamin required for healthy immunological function. According to research, a lack of vitamin C in the diet might weaken the immune system, making the person more prone to illness. 

Mustard greens also contain vitamin A, which helps to enhance your immune system. It accomplishes this by boosting the proliferation and distribution of T cells, a kind of white blood cell that aids in the fight against infection.

Mustard Greens Benefit Heart health

Mustard greens are also beneficial for your cardiovascular system. They’re high in antioxidants, including beta carotene and flavonoids, which can lower the risk of heart diseases and associated mortality. 

According to eight-week research, the higher consumption of leafy greens (especially Brassica) can lower the risk of heart diseases by 15%. Like other Brassica plants, mustard greens contain chemicals that assist in the binding of bile acids in the digestive system. Inhibiting bile acid reabsorption can lower cholesterol levels, which is healthy for the heart. As per studies, steaming mustard greens significantly improves the bile acid-binding effect. So, steamed mustard greens can lower cholesterol levels, making them heart-friendly.

Improved Eye Health

Lutein and zeaxanthin, two antioxidants found in mustard greens, improve eye health. Research suggests that eating foods high in zeaxanthin and lutein may help shield against age-related macular degeneration, the most common cause of blindness worldwide. In particular, these two chemicals help protect the retina from oxidative damage while also filtering out damaging blue light. 

The HealthifyMe Note

Mustard greens are rich in vitamins and minerals your body requires for good health. For example, vitamin C supports immune health, making it essential for your body. Hence, one should ensure enough vitamin C intake throughout the day, and mustard greens can be an excellent choice to fulfil your vitamin C requirement. In addition, cooked mustard greens can provide up to 100% of your daily vitamin A needs. Moreover, many physiological processes, including heart, kidney and lung health, are supported by this vitamin.

Possible Side Effects of Mustard Greens

It May Increase Bloating and Flatulence

Overeating raw and cooked mustard greens can cause gas and bloat due to their high fibre content. If this frequently causes problems, blanching or boiling the greens before using them in other meals will help lessen the risk of bloating and indigestion. In addition, you can use preventive measures to prevent the side effects. For example, drink a lot of water to avoid bloating.

Interactions with Medicines

Vitamin K is vital for blood clotting and is abundant in mustard greens. Therefore, when coupled with mustard greens, drugs like warfarin (Coumadin), both blood thinners, may raise the risk of severe bleeding.

Increased Risk of Kidney Stones

Mustard greens, like spinach, contain oxalates. Oxalates bind to calcium in the digestive system before getting into the bloodstream. Therefore, it can raise the risk of kidney stones in people who are sensitive to them. Furthermore, they can also decrease calcium absorption. So even while one serving per day is unlikely to induce this illness in most people, those who already have kidney stones should cut back on their intake. 

Some cooking techniques can also assist in reducing oxalate levels. For example, research showed that boiling reduced soluble oxalate content by 30-87% and was more effective than steaming (5-53%) and baking (used only for potatoes, no oxalate loss).


Mustard greens, the spicy leaves of the mustard plant, have a reasonable amount of vitamins and minerals. Vitamin C, Vitamin K, and plant chemicals with antioxidant and anticancer properties are particularly abundant. Incorporating mustard greens into one’s diet may help the heart, eyes, and immune system. Because of their peppery, spicy flavour, mustard greens are a fantastic addition to soups, salads, and casseroles. Steam them and combine them with olive oil, garlic, and lemon juice for a simple side meal. 

While they have adverse effects like gas, bloating, and the possibility of kidney stones, this occurs when consumed in large quantities over time. Therefore, their benefits outweigh the drawbacks, making them a healthy addition to one’s diet.
