Arugula, also known as rocket, rucola, or Italian cress, has gained popularity for its distinct peppery flavor and impressive nutrient profile. This leafy green, a member of the cruciferous vegetable family along with broccoli and kale, is a low-calorie addition to any diet that delivers a substantial dose of essential vitamins and minerals. By understanding the key nutrients packed into its tender leaves, you can harness its full range of health benefits.
Nutrient Powerhouse: What is Arugula High In?
Arugula boasts a surprisingly robust nutritional makeup, considering its delicate leaves. It is particularly rich in several crucial vitamins and minerals that support overall health.
Rich in Vitamin K
Arugula is an excellent source of Vitamin K, with a single cup providing a significant portion of the recommended daily value. This fat-soluble vitamin is vital for two key functions in the body:
- Bone Health: Vitamin K plays a crucial role in bone metabolism by helping the body properly absorb and use calcium. Adequate intake is linked to a lower risk of bone fractures and better bone density.
- Blood Clotting: It is essential for producing the proteins required for blood coagulation, ensuring that wounds can heal properly.
A Source of Vitamin A
This leafy green is a good source of Vitamin A, delivered in the form of beta-carotene and other carotenoids. Vitamin A is a potent antioxidant that supports critical bodily functions, including:
- Vision: It is essential for maintaining healthy vision, especially in low-light conditions.
- Immune Function: Vitamin A supports the healthy function of the immune system and promotes cell growth.
Boosts with Vitamin C
Like many leafy greens, arugula contains a healthy dose of Vitamin C, a well-known antioxidant that protects cells from damage caused by free radicals. This versatile nutrient also aids in iron absorption and helps the body produce collagen, which is important for skin health.
Mineral Content: Calcium, Potassium, and More
In addition to its rich vitamin content, arugula provides several important minerals that contribute to its health benefits.
- Calcium: Arugula is a plant-based source of calcium, a mineral fundamental for strong bones, teeth, and proper nerve and muscle function.
- Potassium: This mineral and electrolyte is vital for maintaining healthy blood pressure, heart and nerve function, and proper muscle contraction.
- Magnesium: It works alongside calcium and vitamin K to support bone health and nerve function.
Beyond Vitamins and Minerals: Phytonutrients
The nutritional value of arugula extends beyond standard vitamins and minerals. The green is also rich in beneficial plant compounds known as phytonutrients.
Glucosinolates
These sulfur-containing compounds are responsible for arugula's characteristic pungent, peppery taste. When consumed, the body breaks them down into compounds with potential anti-cancer properties. Research has explored the link between consuming cruciferous vegetables like arugula and a reduced risk of certain cancers.
Antioxidants
In addition to vitamins A and C, arugula contains other antioxidants, including flavonoids like quercetin and kaempferol. These compounds help combat oxidative stress and inflammation, which are linked to various chronic diseases.
Nitrates
Arugula is exceptionally high in dietary nitrates, even more so than beets. The body converts these nitrates into nitric oxide, a compound that helps relax and widen blood vessels. This can lead to improved blood pressure and enhanced athletic performance by allowing more oxygen to reach muscles.
Arugula vs. Other Leafy Greens: A Nutritional Comparison
While many leafy greens offer health benefits, their specific nutritional profiles differ. Here's how arugula stacks up against some common alternatives:
| Nutrient | Arugula (100g raw) | Spinach (100g raw) | Romaine Lettuce (100g raw) |
|---|---|---|---|
| Calories | 25 | 23 | 17 |
| Vitamin K | High (91% DV) | Very High (over 100% DV) | Low (less than 30% DV) |
| Vitamin C | Good (17% DV) | High (34% DV) | Good (22% DV) |
| Calcium | Good (160 mg) | Good (99 mg) | Low (33 mg) |
| Potassium | Good (369 mg) | High (558 mg) | Good (247 mg) |
| Dietary Nitrates | Extremely High (480 mg) | High (approx. 24-38 mg) | Low |
Simple Ways to Add Arugula to Your Diet
Incorporating arugula into your meals is easy and delicious. Its peppery flavor can be enjoyed raw or cooked. For maximum benefits, especially for heat-sensitive vitamins like Vitamin C, it's best to consume it raw.
- In Salads: Use it as a base for salads, or mix it with milder greens for a flavor boost. Pair with sweet fruits like pears or strawberries to balance the peppery taste.
- On Pizza: Add a handful of fresh arugula to a pizza just after it comes out of the oven for a fresh, spicy topping.
- In Sandwiches and Wraps: Replace standard lettuce with arugula to add a zingy flavor to your sandwiches or wraps.
- In Pesto: Substitute basil for arugula to create a peppery and flavorful pesto sauce for pasta or spreads.
- Lightly Sautéed: Gently wilt arugula in a pan with garlic and olive oil for a simple, savory side dish. This mellows its peppery flavor.
Potential Considerations
While arugula is highly beneficial, a few things to keep in mind:
- Blood Thinners: Due to its high Vitamin K content, individuals on blood-thinning medication like warfarin should speak with a healthcare professional before significantly altering their intake of arugula or other leafy greens. Consistent intake is generally recommended rather than large, sudden changes.
- Washing: As with any fresh produce, always wash arugula thoroughly before consumption to remove any potential contaminants.
Conclusion
In summary, when asking what is arugula high in, the answer is a cocktail of health-promoting nutrients, including vitamins K, A, and C, as well as minerals like calcium and potassium. As a cruciferous vegetable, it also delivers beneficial compounds like glucosinolates and nitrates, which support everything from bone and heart health to detoxification and immune function. Versatile and delicious, arugula is a simple but powerful addition to any diet for enhancing your nutritional intake.
