Health Benefits Of Arugula

What is arugula 

Arugula is known under many other names, such as salad or garden rocket, requete or colewort. Despite being mistaken for a type of lettuce, it comes from the Brassicaceae family, making it a cousin of cabbage, broccoli and cauliflower.

Originally from the Mediterranean, nowadays it is easily accessible in most areas of the world. It is typically planted during winter in quite dry areas of southern Europe, North Africa, India, Pakistan and Iran.

Those dark leaves are widely known for their very distinct, peppery taste and can be used in a variety of ways, including salads, and toppings on hot dishes such as soups or pizzas. You can enjoy not only the leafy part of this cruciferous vegetable but also its roots, flowers and seeds.

Historically, it has been used by ancient Romans as an aphrodisiac. Unfortunately, modern science does not support this idea, however, it provides studies showing a wealth of other, even more important health benefits. Arugula, due to its wealth of vitamins, promotes bone and eye health, helps with digestion and weight loss, and reduces the risks of cancer and diabetes.1 Let’s dive into the world of arugula.1

Health benefits of arugula

Promotes bone health 

Arugula has a high calcium content, which greatly improves your bone and tooth health. Calcium is the most commonly occurring mineral in our bodies, so we must provide an appropriate supplementation of it in our daily diet to keep our bones, teeth and muscles strong.

Arugula, as a dark leafy green vegetable, is rich in vitamin K, which is present during bone formation. It improves bone density and helps during healing processes when a bone is broken. Improved intake of this vitamin reduces the risk of any fractures.3

Vitamin K supplementation is essential for people suffering from osteoporosis.

May help prevent cancer 

It has been suggested by scientists that compounds present in arugula can be used in cancer prevention. 

As a cruciferous vegetable, arugula has an abundance of phytochemicals that help in reducing inflammation, promoting healthy cell growth and repair, and slowing down cancer development.

Phytochemicals present in arugula are isothiocyanates, phenolic compounds and carotenoids.

It has been supported by science that phytochemicals can help you with several types of cancer, including lung, ovarian, colorectal and pancreatic cancer. 

There is growing evidence that erucin, a substance you can find in arugula, can kill breast cancer cells and helps get rid of damaged cells in the body. It has been also suggested that the more erucin-rich food you consume, the greater the influence it has over fighting cancer cells.5 

Aids in digestion 

Arugula, as part of the Brassicaceae family, is rich in dietary fibre, especially insoluble fibre. From the two types of fibre, insoluble fibre passes through your gut without being properly absorbed by the body. As arugula is usually enjoyed raw as a part of salads or toppings, it helps your bowel movement and keeps your digestive system healthy.6

Additionally, arugula, as a fibre-rich food with high water content can significantly lower the risk of suffering from constipation.6 

Rocket is not a calorie-dense food, so it can be eaten in large amounts without the worry of eating over your recommended daily calorie intake.2

It has been suggested that people suffering from Crohn’s disease can benefit from a fibre-rich diet. It was observed that patients with Crohn’s disease on a fibre-rich diet spent almost 5 times less time in a hospital over a span of 4 years. 6

People suffering from digestive problems, such as Irritable Bowel Syndrome, will benefit from incorporating more arugula in their diet, as is rich in folate, which helps in the formation of digestive acids.

May reduce risk of heart disease 

Arugula has numerous benefits for your cardiovascular health.

It has been shown that it reduces the risk of creating unwanted blood clots thanks to the presence of flavanols that decrease the activation and production of platelets.8

Platelets are cells in our blood that react to blood vessel injury by creating clots. Too many of them can cause jams in our veins and lead to damage, such as cardiovascular disease or stroke.

Flavonols in arugula, especially kaempferol and quercetin, keep your cardiovascular system healthy by reducing inflammation.10

Additionally, eating foods rich in quercetin, such as rocket, can reduce blood pressure, which can be especially helpful for patients with hypertension.10 

Arugula is a rich source of vitamin A, especially beta-carotene, which can positively affect your heart health, as it reduces inflammation, increases levels of good cholesterol and is a strong antioxidant.11 

May aid in weight loss

Arugula can be your best ally when it comes to weight loss. This cruciferous vegetable has a very low-calorie count, averaging 25 kcals per 100 grams of fresh produce. What is more, it is almost 92% pure water, making it extremely diet-friendly, keeping you hydrated and satiated at the same time.2

Arugula is rich in beta-carotene, a carotenoid that is famous for acting directly on your fat tissue, helping you shed unwanted fat from your body. Studies have shown that carotenoid-abundant diet aids in treating obesity by regulating your insulin and lipids levels.11 

Arugula has a high dietary fibre content, especially insoluble fibre that cannot be digested by the human body. It, therefore, makes you feel full for longer, decreasing cravings and keeping your diet in check.6

Other health benefits:

  • Makes you live longer: Arugula is high in fibre. One study shows that people who consume large amounts of foods rich in fibre had a 22% decreased risk of dying during a 9-year-long experiment6 
  • Helps with Type 2 Diabetes: As it helps in insulin and fat management, beta-carotene in arugula is one of the main supporters of treating Type 2 Diabetes. Additionally, as eating arugula reduces inflammation and increases the levels of antioxidants in your body, it reduces the damage diabetes causes to your body11
  • Helps with pregnancy: Arugula is a folate-rich food. Folate a vitamin from the B group, aids in DNA production, as well as helps in the development of other genetic material. Folate helps people during pregnancy to avoid womb and fetus defects12

Nutritional facts
