Things You Didn’t Know About ”Kale”

Are you familiar with kale, the nutrient-packed, vibrant green vegetable? This superfood is gaining international attention, often used by celebrities worldwide in salads, smoothies, and even as an ingredient in green juices for both beauty and health benefits. In this article, we’ll explore the high nutritional value of kale that has captured the world’s interest, and provide tips on how to deliciously incorporate it into your daily meals.

Kale, a leafy green vegetable, belongs to the Brassica family, commonly known as cruciferous vegetables, alongside cabbage and broccoli. Renowned for its nutritional richness and health benefits, kale is a robust source of Vitamin K, Vitamin C, Vitamin A, minerals such as calcium, magnesium, potassium, dietary fiber, and antioxidants.

Its leaves are broad and have a wavy texture, presenting a unique and visually appealing appearance. With a crisp texture, raw kale is distinctive for its crunchy bite. While the leaves are typically dark green, some varieties exhibit a reddish hue, providing vibrant colors for salads and dishes.

Additionally, kale finds versatile usage in smoothies, soups, stir-fries, and more. Whether consumed raw or lightly cooked through steaming or baking, kale offers a delightful and nutritious addition to various culinary creations.

Originating from the Mediterranean coast, kale thrives in warm climates and allows year-round cultivation and harvesting. In Japan, it is cultivated in prefectures such as Ibaraki, Shimane, Ehime, Fukuoka, and Kagoshima. Moreover, kale’s ability to withstand cold temperatures makes it suitable for cultivation in colder regions, ensuring its availability during autumn and winter. Due to its nutritional value and culinary versatility, kale has become a popular choice for health-conscious diets and diverse culinary creations.

Kind of “Kale”

1. Curly Kale (カールズバッドケール):
   • Curly Kale, as the name suggests, has a unique wavy leaf structure. Its wide green leaves are known for their relatively tender texture. Generally, it combines both deliciousness and visual appeal, making it suitable for use in salads, soups, and smoothies.
2. Lacinato Kale (ラシオールケール):
   • Lacinato Kale features flat and broad leaves, offering a distinctive texture. It is commonly used in salads and stir-fries, where its unique flavor profile stands out.
3. Red Russian Kale (レッドラッセルケール):
   • Red Russian Kale is characterized by its distinctive purple or reddish leaves. Due to its visually appealing appearance, it is often used in salads and dips.
4. Siberian Kale (シボレーケール):
   • Siberian Kale is a cold-resistant variety that thrives in chilly climates. With flat and tender leaves, it is well-suited for soups and salads
5.  Toscano Kale (トスカーナケール):
   • Toscano Kale, a type of Lacinato Kale, is known for its long and narrow leaves. Frequently used in Italian cuisine, it adds flavor to simple dishes.

These are some representative types of kale, and there are various other varieties depending on the region and producer. Since the flavor and uses of kale can vary between types, it’s a good idea to choose based on personal preference and the intended culinary application.

Nutrients in “Kale” and their benefits

❶ Potassium and Its Benefits

Kale is rich in the mineral known as “potassium.” As potassium, like vitamins, cannot be produced within the human body, it is crucial to obtain it through a well-balanced diet. Potassium plays a vital role in balancing the effects of “sodium,” which is abundant in table salt. Here are four recognized benefits and effects of potassium:

1. Alleviation of Edema (Swelling):
   • Potassium helps reduce fluid retention, aiding in the alleviation of swelling.
2. Prevention of High Blood Pressure:
   • Maintaining a balance between potassium and sodium can contribute to the prevention of high blood pressure.
3. Stroke Prevention:
   • Adequate potassium intake has been associated with a lower risk of stroke.
4. Bone Density Improvement:
   • Potassium plays a role in promoting bone health and may contribute to improved bone density.

For individuals, especially those during lactation, potassium is considered an essential nutrient. Being mindful of including potassium-rich foods in your diet is recommended to enjoy these health benefits!

❷ Vitamin K and Its Effects

Vitamin K is one of the prominent vitamins abundantly found in kale. It is a fat-soluble vitamin with a role in blood clotting. There are two types of vitamin K: vitamin K1, found in green leafy vegetables, seaweed, and green tea, and vitamin K2, synthesized by intestinal bacteria within the body. Here are four recognized effects and benefits of vitamin K:

1. Facilitation of Calcium Absorption:
   • Vitamin K aids in the absorption of calcium.
2. Prevention of Calcium Outflow from Bones:
   • It helps prevent the leaching of calcium from bones.
3. Hemostatic Properties:
   • Vitamin K contributes to clotting, assisting in stopping bleeding.
4. Inhibition of Arterial (Vascular) Calcification:
   • It helps suppress the calcification that leads to hardening of arteries (blood vessels) from calcium deposition on their inner walls.

Vitamin K activates a calcium-binding protein called osteocalcin in bones, promoting the deposition of calcium and preventing its outflow. Additionally, it stimulates collagen production, making it a vitamin utilized in the treatment of osteoporosis.

❸ Vitamin A and Its Effects

“Kale” stands out as an excellent source of Vitamin A. Vitamin A is a vital nutrient essential for vision, immune function, skin health, and cellular growth and development. Kale contains ample Vitamin A, contributing positively to these aspects of health. Particularly, it supports the normal function of the optic nerve and enhances night vision, aiding in improved visibility during nighttime or in low-light conditions. The recognized effects and benefits of Vitamin A include:

1. Enhancement of Optic Nerve Function and Night Vision:
   • Vitamin A contributes to the normal function of the optic nerve and improvement of night vision.
2. Reinforcement of Immune Function:
   • It strengthens the immune system.
3. Antioxidant Properties:
   • Vitamin A has antioxidant effects, protecting cells from oxidative stress, slowing down cellular aging, and preventing various chronic diseases.
4. Strengthening of Skin Epithelium and Inhibition of Dryness and Wrinkles:
   • It fortifies the skin’s outer layer, suppressing dryness and wrinkles.

Obtaining Vitamin A through a balanced diet is crucial for healthy growth, vision, immune function, cell differentiation, and maintaining robust skin.

❹ Summary of kale nutrients and their benefits

How to choose fresh “Kale”

Tips for Choosing Fresh Kale

When selecting fresh kale, paying attention to four key points is crucial:

1. Leaf Appearance Matters: Healthy kale exhibits a vibrant, dark green color and a lush, lively appearance. Choose leaves that are vibrant and well-hydrated, avoiding wilted or discolored ones, as these may indicate lower freshness.
2. Consider Leaf Shape and Density: Opt for kale with new leaves radiating from the center and densely packed foliage. This characteristic ensures a crisp and crunchy texture. If leaves are sparse or spread out unevenly, it may indicate a lack of freshness.
3. Size of the Leaves: Generally, smaller and tender leaves tend to indicate freshness. However, consider the kale variety, as leaf size can vary. Also, check if the leaves have been exposed to sunlight, as sunlight exposure enhances nutrient content, flavor, and nutritional value.
4. Check the Cut End: Ensure that the stem end is firm and not discolored. Select kale with a clean cut, as those with a fresh cut retain more nutrients. Avoid kale with a wilted or darkened cut end, as it may compromise nutritional quality.

By keeping these points in mind, you can select kale that promises optimal flavor and nutritional benefits.

How to preserve “Kale”

Effective Ways to Store Fresh Kale

To ensure kale stays fresh and delicious, understanding proper methods and conditions for storage is crucial. Here are detailed instructions on common methods for storing kale:

1. Refrigeration: Kale is best stored in the refrigerator. Place kale in a bag or wrap it in plastic wrap, then store it in the vegetable compartment of the refrigerator. To prevent spoilage, especially in humid conditions, consider wrapping it in kitchen paper or placing it in a breathable bag.
2. Freezing: Kale can also be frozen. After washing and thoroughly drying it, cut it into convenient sizes, and then divide it into freezer bags. Freezing allows kale to retain freshness for an extended period while preserving some of its nutritional value.
3. Handling Cut Ends: When cutting kale, store it effectively by placing it in a plastic bag. However, for optimal freshness, it is recommended to store kale before cutting. Ensure that cut ends do not dry out during storage, and if there are leftovers, freezing can be a convenient option.
4. Combatting Moisture: Kale is sensitive to humidity, so proper humidity control is essential. To reduce moisture absorption, place desiccants in storage containers or wrap kale in kitchen paper to manage humidity effectively.
5. Usage Recommendations: It is advisable to use kale as soon as possible. Utilize it in salads, soups, smoothies, or other dishes while it is still fresh.
6. Nutritional Changes: Over an extended storage period, kale’s nutritional value may decrease. Vitamins C and K, in particular, are susceptible to oxidation, so consuming kale while fresh is recommended.

These are the fundamental steps for storing kale in a fresh and appetizing state. Optimal storage methods may vary based on individual circumstances, so using kale promptly or choosing effective storage methods for leftovers is essential.
