What are microgreens?

Treasured for their densely packed nutrients and intense flavours, microgreens are both the latest superfood restaurant trend and an increasingly popular at-home hobby. Microgreens are younger and smaller versions of edible vegetables, herbs, grains and grasses.

Unlike the fully grown greens that can take months to grow, these immature plants can be harvested and eaten within 7-21 days, depending on the variety.

If you're wondering why you would want to downsize your veg, the headline is that microgreens are actually more nutrient-rich than larger greens. On top of this, they're faster and easier to grow and boast a more intense flavour.

We're not suggesting you should replace your usual veg with these mini superfoods, but you might like to add them to a salad, sprinkle on top of fish or steak, put them in a sandwich, or whizz them into a smoothie. We explore why.

What are the benefits of microgreens?

Microgreens are rich in vitamins, minerals, and other compounds that help keep us healthy. This is also true of their larger counterparts, but microgreens have 4-6 times more nutrients¹. For example:

• Red cabbage microgreens have 40 times more فيتامين E and six times more فيتامين C than fully grown red cabbage. This helps to fight disease and skin ageing, among other things.

• Coriander microgreens have three times more beta-carotene than fully grown coriander. This antioxidant converts to فيتامين أ in the body, which we need for a strong immune system and good eye health.

Disease-preventing benefits of microgreens

A recent surge of scientific interest in microgreens has also uncovered their potential disease-fighting power. As of yet, no long-term studies exist to confirm their role in disease prevention, but their anti-inflammatory, high antioxidant, and anti-diabetic effects show promise for²:

Because they are small, even people without garden space can grow microgreens at home in the kitchen. But before you swap your regular veg drawer for seeds and seed trays, remember you can't replace vegetables with microgreens. This is because of the cost and volume you'd have to eat to get the nutrition you need.

What you can do is include them as extras in your meals to enrich your diet with a more diverse range of health-boosting compounds.

Buying or growing microgreens

Microgreens are available to buy in many supermarkets and health food stores, but these can be pricey. Shop-bought microgreens can be sold either pre-planted in trays or pre-cut in containers. When buying, remember that pre-cut microgreens aren't as fresh and are therefore less nutritious.

A more budget-friendly alternative is to grow them yourself - either in your garden or on a kitchen shelf - as their seeds are much cheaper and equipment is minimal. This also ensures you can eat microgreens at their freshest, which means better flavour and maxium nutrients. So long as you buy organic seeds, you can also avoid pesticides, which can be harmful for both people و environment.

To make it even easier, while preserving their freshness, you can purchase prepared microgreen growing kits. However, this is typically the most expensive option.

These are the Royal Horticultural Society (RHS) has five simple steps for how to grow your own microgreens:

1. Find a small seed container - use small seed trays or recycle a food tub as a container. Then cut some kitchen roll or felt to the shape of the container and place it in the bottom.

2. Sow your seeds - first wet the felt or kitchen roll and then sprinkle your seeds on top.

3. Give them a warm home - place them either on a warm windowsill or in a glasshouse. The ideal temperatures for germination are 18-22°C (65-72°F).

4. Keep them moist - as the seeds begin to grow, regularly mist them or water them carefully, remembering they are delicate.

5. Taste test them as they grow - the flavours will develop gradually, so you can regularly taste them until you're happy to cut them with scissors and add to sandwiches, sprinkle in salads, garnish meats, or blend into smoothies. The seed packets should also give an idea of how many days before they are ready to harvest, depending on the variety, typically between 7-21 days.

Some of the most popular seeds for microgreens include:

• Basil.

• Mustard greens.

• Cabbage.

• Kale.

• Rocket.

• Spinach.

• Radish greens.

• بازلاء.

• Watercress.
