KALE MICROGREENS
Kale – A Green Powerhouse
Kale, a leafy green vegetable, has a rich history that dates back thousands of years. Kale is a member of the Brassicaceae family (like broccoli, arugula, cabbage, and radish) and a descendant of wild cabbage, native to Europe and Asia Minor, and has been grown and consumed for nearly 4,000 years.
It originated in the eastern Mediterranean and Anatolia and was cultivated for food beginning by 2000 BCE at the latest. The Greeks and Romans grew kale and similar leafy greens, which they used for various purposes, including as a cure for drunkenness. [2]
The cultivation of these wild plants started around the 6th century BCE. In the Middle Ages, kale was one of the most widely eaten green vegetables. Over time, different kale cultivars have been developed, including curly-leaved and flat-leaved varieties leading to the modern kale we know today, which has a much larger leaf and a likely better flavor profile.
| Scientific Name | Brassica oleracea var. acephala |
| Common Name | Kale |
| Plant Family | Brassicaceae |
| Etymology | The term ‘kale’ is derived from the Northern Middle English ‘cale’ (or ‘cole’) for ‘cabbage.’ |
Kale microgreens, the young kale seedlings, have gained popularity recently due to their high nutrient content and culinary versatility. They are harvested just a few weeks after planting when the first true leaves appear. Despite their small size, kale microgreens pack a nutritional punch, containing higher concentrations of vitamins, minerals, and antioxidants than mature kale.[1]
Varieties of Kale
Kale has several types, each with unique taste, texture, and color. Some of the popular varieties include:
| Curly Kale | Characterized by its ruffled leaves and fibrous stalk, it is the most common type in grocery stores. |
| Lacinato Kale | Also known as ‘dinosaur kale,’ it has dark blue-green leaves with a slightly wrinkled texture. |
| Red Russian Kale | This variety has flat, fringed leaves that resemble oak leaves. The leaves are a reddish-purple with a sweet, robust flavor. |
| Siberian Kale | Known for its hardiness, it has large, tender leaves ideal for salads and smoothies. |
Each of these varieties can also be grown as microgreens, offering a range of flavors and textures for culinary use.
This brief overview provides a foundation for understanding the rich history and nutritional benefits of kale and its microgreens. As we delve deeper into the topic, we’ll explore this green powerhouse’s cultivation process, health benefits, and culinary uses.
There are hundreds of plants, herbs, roots, and fruits you can grow and eat as microgreens. Explore my post “Top 30 Microgreens You Can Easily Grow Indoors.”

| Lutein + zeaxanthin (6260 µg, 104.33%) | Lutein and Zeaxanthin are carotenoids that help to protect the eye from damage caused by harmful light, which may reduce the risk of age-related macular degeneration. |
| Vitamin C (93.4 mg, 103.78%) | For every tissue in your body to grow, develop and recover, you need vitamin C. It helps heal wounds and maintain healthy bones, teeth, and skin. It is also an antioxidant that helps protect cells from damage caused by free radicals. |
| Riboflavin (0.347 mg, 26.69%) | Riboflavin, vitamin B2, converts food into energy, so it’s necessary for growth and development. It also helps to maintain healthy skin, eyes, and nervous systems. |
| Vitamin B-6 (0.147 mg, 11.31%) | In addition to supporting the metabolism of proteins and red blood cells, Vitamin B6 is a water-soluble vitamin requiring good nerve function. Vitamin B-6 also helps maintain healthy skin, eyes, and liver. |
| Folate (62 µg, 15.50%) | Folate is a vitamin B that helps produce DNA and RNA, essential for adequately developing the fetus’ nervous system. Folate also helps maintain healthy skin, hair, and eyes. |

| Manganese, Mn (0.92 mg, 40.00%) | Manganese is essential in metabolizing amino acids, cholesterol, and carbohydrates. |
Interestingly, the high Vitamin K content in kale microgreens can be attributed to the plant’s ability to synthesize phylloquinone during the early stages of growth. This unique feature of microgreens makes them a nutrient-dense food option.
Incorporating Kale Microgreens into your diet can significantly contribute to Vitamin K intake, promoting better blood and bone health.
In the next section, we will explore the culinary uses of kale microgreens, showcasing their versatility beyond their nutritional value.
Health Benefits of Kale Microgreens
Kale microgreens, despite their small size, are a nutritional powerhouse. They are rich in vitamins, minerals, and antioxidants, contributing to their numerous health benefits.
| Preventing Osteoporosis | Vitamin K is crucial in promoting bone health and aiding in blood clotting. A diet rich in kale microgreens can help ensure adequate intake of this essential nutrient, potentially reducing the risk of bone fractures and bleeding disorders. |
| Immune Health | Apart from vitamin K, Kale microgreens are teeming with nutrients such as vitamins A, C, and calcium. These nutrients are known for their immune-boosting properties, helping to protect the body against various diseases. |
| Reduce Chronic Disease | Moreover, kale microgreens are rich in antioxidants. These substances help to protect the cells against free radicals, a kind of unstable molecule that can damage your cells. This antioxidant effect may reduce the risk of chronic diseases, such as heart disease and certain types of cancer. |
| Bioavailable | Furthermore, research suggests that the nutrients in kale microgreens are highly bioavailable. This means they are easily absorbed by the body, ensuring you get the maximum health benefits from consuming these greens. |
| Medicinal Properties | Kale microgreens also have potential medicinal properties. Some studies suggest that they may have anti-cancer properties, although more research is needed in this area. |
| Eye Health | A deficiency in vitamin A can lead to night blindness and, in severe cases, total vision loss. The macula, a part of the retina, contains high concentrations of lutein and zeaxanthin. They act as antioxidants, protecting the eyes from damage caused by free radicals. They also help to filter out harmful high-energy blue wavelengths of light, acting as a natural sunblock for the eyes. |
Adding kale microgreens to your diet is a simple but efficient way of increasing nutrient intake and promoting general health. Their potential health benefits and medicinal properties make them valuable to any diet.
As we delve deeper into kale microgreens, let’s explore how to cook with these nutrient-dense greens in the next section.
Cooking With Kale Microgreens
Kale microgreens are a nutrient-dense food that can be consumed raw and cooked. However, the method of preparation can affect its nutrient content.
C is sensitive to heat and water, so boiling kale microgreens can significantly lose this nutrient. Eating raw kale in salads or smoothies can help preserve its vitamin C content.
On the other hand, cooking kale microgreens can make certain nutrients more bioavailable. For example, steaming kale microgreens can increase the availability of beta-carotene, a precursor to vitamin A. Cooking can also reduce the levels of oxalic acid. This compound can bind to minerals like calcium and iron, reducing their absorption.
Kale microgreens can be a versatile addition to your meals, adding a nutritional punch and a fresh, slightly peppery flavor. Here are some ways you can incorporate them into your cooking:
| Salad | Toss kale microgreens with purple cabbage, caramelized onions, and crispy quinoa for a refreshing and colorful salad. Drizzle with your favorite dressing and enjoy. |
| Cheese Pizza | Top your favorite pizza crust with parmesan and ricotta cheese, pistachios, and a generous handful of kale microgreens for a gourmet twist on pizza night. |
| Avocado Toast | Upgrade your avocado toast by adding a layer of kale microgreens. For some heat, finish with a few drops of olive oil, Himalayan pink salt, and a pinch of red pepper flakes. |
| Omelets or Scrambled Eggs | Add red Russian kale microgreens to your morning eggs for a nutritious start. |
| Veggie Bowls | Create a nutrient-dense veggie bowl with your choice of grains, vegetables, protein, and top with kale microgreens for added flavor and nutrition. |
Remember, the possibilities are endless when cooking with kale microgreens.
