Surprising Arugula Benefits That Scientists Are Talking About

Written by Varsha Patnaik

Arugula is the dark horse of greens. While arugula benefits range from improving eyesight to reducing the risk of cancer, it has been behind other greens like kale, broccoli, and spinach in popularity. But that’s changing for good. Modern research is providing supporting evidence to the claimed benefits of arugula and it is finding a place as “specialty greens” in stores. Is arugula lettuce? Nope. If you want to get to know this peppery, leafy green, read ahead.

A Meeting With Arugula

Take a stroll around the garden in a Mediterranean country, and you may find a little green herb with deeply cut leaves, stems that are a gradient of green to purple, and tiny white flowers. Meet wild arugula or arugula rocket. You can pick it up and eat it just there. A refreshing hot peppery taste, quite similar to mustard, may linger on your mouth if you have caught it young. If it’s older, you may be taken aback by the hint of bitterness there. Now you know the answer to what arugula tastes like.

There are many varieties of this herb growing in the Brassicaceae family with more popular members like broccoli, kale, cauliflower, mustard, radish, and cabbage. Arugula has so many names that you may have a hard time keeping track of them, but the most common are eruca sativa (scientific name), rocket arugula, roquette (french), rucola, and Italian cress. This herbaceous plant that prefers sunny weather and a cool climate packs a super nutritious punch, with a wide array of phytochemicals, vitamins, and minerals. To top it off, arugula is low in fats, carbohydrates, and calories.

The richness of the nutritional content in arugula, and the presence of sulfur-containing secondary metabolites called glucosinolates translates to wonderful arugula benefits for health.

Let’s dive deeper into what arugula leaves, cooked and raw, can do for your body!

What Does Arugula Do For Your Health?

The health benefits of arugula are similar to those of other greens and veggies from the Brassica family because of its high concentrations of phytochemicals, antioxidants, essential minerals, and the presence of glucosinolates.

  • Keeps The Bones And Teeth Strong

You can keep your bones and teeth in top condition with regular consumption of arugula. That’s because arugula contains high levels of calcium and vitamin K. Calcium is needed to form bones and teeth, whereas vitamin K serves as the glue that helps to deposit calcium and bind them together. A study conducted to understand the role of arugula in improving osteoporosis revealed that arugula may improve symptoms of osteoporosis, improve absorption of calcium and prevent bone impairment and damage (4, 12).

  • Improves Vision And Maintains Eye Health

You may be at risk of developing cataracts and AMD (age-related macular degeneration which presents as blurry vision and progresses to near blindness over time). With arugula in your diet, you can lower the risks. A research review notes the importance of lutein, the main carotenoid in arugula, as an important component of maintaining vision and managing your eye health (5).

  • May Provide Protection Against Cancer

You may have heard about the anti-cancer properties of kale, broccoli, and other brassicas. A number of studies have revealed that consumption of brassicas may lower the risk of lung cancer, colon cancer, stomach cancer, and rectal cancer most consistently. Further research is needed to understand how exactly it works, though. (6).

Arugula in particular is just as powerful and a handful of this crunchy green in your diet can bolster your body against different types of cancer. The glucosinolates in the arugula break down to form compounds called isothiocyanates. Erucin, the most important isothiocyanate from arugula, is being widely studied for its anti-cancer properties. So, how does it work? Research points towards different mechanisms like (7):

  1. Inhibiting the action of enzymes that activate carcinogens in the body.
  2. Introduction of enzymes that can detoxify the body of carcinogens.
  3. Inhibiting the multiplication of cancerous cells by stopping their cell cycle.
  4. Inducing cell death for malignant or premalignant cells in the body.
  • Helps To Control Blood Pressure

Eating arugula may benefit your blood pressure. In a study conducted to find support for the traditional use of arugula as a hypertensive, researchers could prove its vasodilatory and cardiotonic effects. That means arugula can keep your heart pumping better to ensure smooth blood flow and also relax the blood vessels. The presence of erucin and flavonoids like quercetin supports this action of arugula. So, you can keep your blood vessels happy and stress-free with arugula in your diet (8).

  • Safeguards Your Cardiovascular Health

Arugula benefits continue and serve you up more good news: you can reduce the risk of heart diseases with arugula on your plate. A study conducted to understand the antiplatelet aggregation and antithrombotic effects of arugula has provided evidence that arugula is a safer and more effective way to protect your heart. Arugula contains flavonoids like kaempferol, quercetin, and isorhamnetin which work to prevent thrombosis (blood clotting) in the vessels without the risk of inducing bleeding (9).

  • Supports Your Immune System

Your immune system is your body’s best friend, fighting against all that may harm you from the outside in. But there’s a catch. When your body becomes a battleground, cytokinetic storms rage and that puts you in serious jeopardy. Arugula has been noted to have a suppressive effect on inflammatory cytokines. The result? Your immune system can function without getting itself too heated up and causing more harm than good to you. The credit goes to the antimicrobial properties of arugula as well as the flavonoids that it contains (10).

  • Reduces Your Risk Of Developing Diabetes

Arugula is a great food for diabetics as it is extremely low in fats, sugars, and carbohydrates and rich in antioxidants. And it gets better, because one of the most important health benefits of arugula may be its role in reducing the risk of diabetes and even being a potential treatment for type-2 diabetes (11).

The antioxidant in arugula, known as alpha-linoleic acid (ALA), can improve insulin sensitivity, lower blood glucose levels and reduce oxidative stress related to diabetes which is often a precursor to major health issues (12).

  • Protects Your Gut And Prevents Ulcers

Gastric urease, a compound produced by certain harmful bacteria can cause gastritis, stomach ulcers, and a host of other problems in the stomach. Arugula, a knight in shining armor, can inhibit the production of urease and successfully prevent or even treat stomach ulcers and protect the overall health of your gut. A study conducted to find supporting evidence for the traditional treatment of stomach ulcers with arugula has noted its tremendous role in preventing stomach ulcers and even stomach cancer (13).

You can get all these arugula benefits by making it a part of your healthy diet. So, let’s take a look at some of the best ways to use arugula.

How Can You Use Arugula Leaves?

You can get really creative with arugula in the kitchen. It’s truly a versatile green that adds a nice, flavorful kick.

  • Mix It In Salads

Really, salads do not have to be boring. If you want just a green bowl, combine lettuce and arugula for a well-balanced combination of flavors. Drizzle with olive oil, a dash of lemon, and sprinkle a little salt and pepper. For more colorful salads, arugula combines well with citrus like oranges and cherry tomatoes, fruits like figs and watermelon, fish and chicken in salads. You can create your plate of color and enjoy the crispy, and distinctive flavor of arugula leaves.

  • Throw It On As Toppings

In Italy, it has become a common practice to throw a fistful of fresh young arugula leaves on pizzas as soon as they come out of the oven! You can take inspiration from that and throw it on steaks, roasts, or baked stuff for an added layer of complexity for your palette. You can also top your wraps and sandwiches with arugula.

  • Sass Up Your Seasoning Game

You can also chop up some fresh arugula and use it where you would traditionally use parsley or chives for a varied flavor profile.

  • Stir It In Stir-fries

You don’t need to always have it raw. Cooked arugula is a little milder in flavor and works wonderfully in stir-fries and pasta dishes.

  • Turn It Into A Dipping Sauce

Are you making fries or roasts and want a healthy dipping sauce on the side? Try arugula with basil (or solo) with mayonnaise/ greek yogurt for a herby, creamy, and yummy dip.

  • Make Arugula Pesto

Not only basil, but arugula can do an excellent job as pesto. Use pine nuts and the usual ingredients and simply replace basil with arugula for a distinct pesto pasta that you’ll want to have again and again.

As long as you are not overcooking arugula, you are good to use it anyhow you want in salads, wraps, sandwiches, fries, sauces, and even gravies. It cooks really fast so you don’t want it to wilt too much and turn bright green.

Is arugula healthy? A big resounding yes. Is it tasty? Sure, it’s wonderful! So should I go on an arugula diet? Well, that’s a maybe. Let’s look at this consideration from various angles.

Arugula In Diet: How Safe Is It?

There are a few things to take into account before you go wild over wild rocket! There are no studies to suggest that arugula is bad for you. On the contrary, frequent consumption of arugula can provide a host of health benefits. But you need to follow certain precautions:

  • If you are taking blood thinners, the vitamin K in arugula may interact negatively with the medication. Talk to your doctor about incorporating arugula into your diet.
  • If you eat too much arugula, you may experience bloating and mild stomach discomfort. So, don’t think of fulfilling all your calorie needs with arugula.

In a nutshell, arugula is a wonderful green leafy vegetable to add to your diet, not only for the wonderful health benefits it brings to the table but also for the unique taste it adds to your food. You can forage wild rockets or source it from the local farmers or your nearest grocery. It is really easy to grow too, btw!
