One of the new buzzwords lately is microgreens. Also known as micro herbs or vegetable confetti, they have been around for a while, having been introduced in California restaurants in the 1980’s. Even so, many of us are just now learning what they really are and how to use them.
Simply, they are young vegetable greens that are one to three inches tall, have an aromatic flavor with a concentrated nutrient content and come in a variety of colors and textures. Besides their rich flavor, they add splashes of color to many dishes.
Microgreens are considered baby plants, somewhere between a sprout and a baby green. Sprouts don’t have leaves and their growing cycle is in between two and seven days whereas microgreens’ cycle is seven to twenty-one days after germination and once they have their first leaves. They are similar to baby greens but only their leaves and stems are edible. Also, unlike baby greens, they are smaller in size and are sold before they are harvested.
VARIETIES. The term “microgreens” encompasses many different varieties and are grown using seeds from different plant families like cauliflower, broccoli, cabbage, radish, lettuce, endive, dill, carrot, celery, garlic, onion, beet, spinach, melon, cucumber and squash.
Microgreens are not limited solely to vegetables. Cereals such as rice, oats, wheat, corn, barley and legumes like chickpeas, beans and lentils can be grown into them also.
In most cases, they taste like more concentrated versions of the full-sized plants that they would normally become. Thus, taste varies widely from neutral to spicy, sour or bitter. It all depends on the variety, but the one thing that they all have in common is that the taste is usually strong and concentrated.
NUTRITION AND HEALTH BENEFITS.
Their nutrient content is concentrated so they tend to have higher levels than their mature counterparts, sometimes up to a whopping nine times higher. Microgreens also have wider varieties of polyphenols and other antioxidants. Most tend to be rich in potassium, iron, zinc, magnesium and copper.
Many studies have been conducted to measure the vitamin and antioxidant concentration in commercially available microgreens. Compared to levels recorded in the USDA National Nutrient Database for mature leaves, studies have shown that the levels in microgreens are 40 times higher than in their more mature counterparts.
Eating vegetables has long been linked to lowering the risk of many diseases. Since they contain such high concentrations of nutrients, they may reduce the risk for:
*heart disease because of the polyphenols, compounds that are packed with antioxidants and other healthy nutrients, that lower the risk of heart disease by lowering triglycerides and bad cholesterol.
*Alzheimers, polyphenols help keep this at bay also.
*diabetes, antioxidants help reduce the amount of stress that can prevent sugar from properly entering cells. Fenugreek microgreens enhanced cellular sugar uptake by 25 to 44 percent.
*certain cancers are directly affected by some of microgreens’ nutrients.
WAYS TO EAT. Microgreens are so versatile in ways to consume them. They can be incorporated into wraps, sandwiches and salads like you would their mature plants. They also work well in smoothies and in juices. Added to soups and omelets, they add flavor as well as nutrition. They are also popular as garnishes on pizza.
They are amazing at adding to the flavor profile of your favorite foods, not enough to take away from the original flavor but adding just a little more “punch” to your favorites. By choosing the variety, you can add a touch of savory or sweetness.
HOW TO GROW. Besides being bought at the supermarket, they are easy to grow at home, whether outside in a green house or inside on a windowsill. The good thing is that they can be grown year around, providing a steady supply of fresh produce without needing much effort or time.
The supplies are fairly simple too. Perhaps the most important detail is to start with quality seeds. Their seeds are no different than the seeds you would put in your garden, it’s just how they are grown and harvested. You also need a good soil or growing medium and either enough sunlight or ultraviolet light provided to them from 12 to 16 hours per day.
Microgreens can be grown in a container or on a grow mat. Grow mats can be as sophisticated as purchasing a regular grow mat or using a moistened paper towel or other natural fiber such as jute or coconut. Whichever method you choose, simply sprinkle the seeds on top, mist them and cover with a plastic lid. Check them daily and mist to keep them moist.
A couple of days after germination, remove the lid to expose them to light and water once a day while they grow and gain color. After seven to ten days, they are ready for harvest.
SAFETY. There are generally no safety issues with eating them if you take a couple precautions. Buy seeds from a reputable company and use a growing medium that is free of contaminants. Harmful bacteria like salmonella and E. coli can live in contaminated soil. Peat, perlite and vermiculite are popular growing mediums. If you use growing mats, make sure you only use them once and start with a new one for each planting.
Microgreens are much safer to consume than sprouts. For one thing, only the leaves and stems are consumed and not the root and seed. They are also grown in less warm and humid conditions.
Microgreens offer a little twist on taste and texture when compared to regular vegetables. For picky eaters, it may be easier for them to go for these instead of the mature vegetables that they have a disdain for. They also offer an extra flavor punch and add splashes of color to sometimes ordinary dishes.
On top of that, it’s always nice to see greenery growing, especially in long winter months. They will add a bit of color to your windowsill and there is nothing easier than snipping off a few pieces when cooking. They are quick, easy and fun…what more could we ask from them!
