The study that put red cabbage microgreens on the heart-health map
A pivotal study published in 2016 (Journal of Agricultural and Food Chemistry) by a team of researchers from the USDA and University of Maryland tested red cabbage microgreens in an animal model of heart disease. They wanted to see if eating microgreens would have a different impact than eating the same vegetable in its mature form. Here's what they did:
-
They took 60 mice prone to obesity (and related metabolic issues) and fed them a high-fat diet to induce high cholesterol levels and other risk factors.
-
The mice were divided into groups: some got no cabbage, some got freeze-dried mature red cabbage added to their diet, and some got freeze-dried red cabbage microgreens added (the amount was nutritionally equivalent to about a cup of vegetables per person per day).
-
After several weeks, they checked weight gain, cholesterol levels, liver health, and inflammation markers.
The results were impressive:
-
Both the mature cabbage and microgreen groups fared better than the high-fat diet alone. The mice that ate cabbage (in any form) had lower blood cholesterol levels and less liver inflammation than the mice that ate the high-fat diet without any cabbage.
-
Importantly, the mice that ate red cabbage microgreens had the best results of all. They ended up with significantly lower LDL ("bad") cholesterol levels than even the mice that ate mature red cabbage. The microgreen group's LDL was significantly lower than the control high-fat diet group's LDL, a substantial drop.
-
The microgreen group also had lower levels of liver cholesterol and triglycerides (fat build-up in the liver can be a sign of metabolic issues) compared to others. Specifically, adding microgreens cut harmful cholesterol esters in the liver by more than half and significantly reduced liver triglyceride accumulation.
-
Another benefit observed was less weight gain in the microgreen-fed mice. Despite all groups eating a high-fat base diet, those with red cabbage (especially microgreens) gained less weight, suggesting an improvement in metabolism.
-
Additionally, the microgreen-supplemented mice had lower levels of inflammatory cytokines (cell signals) associated with cardiovascular risk, indicating reduced inflammation in the body. This means microgreens not only influenced cholesterol but also inflammation - a key player in heart disease.
The scientists concluded that red cabbage microgreens can help prevent high cholesterol and weight gain in a way that could translate to heart health protection. In plain English, the microgreens helped prevent the rise of cholesterol (hypercholesterolemia) and other risk factors, suggesting they may protect against cardiovascular disease.
What gave microgreens the edge over the mature cabbage? The study noted that the microgreens contained higher amounts of polyphenols and glucosinolates (beneficial plant compounds) compared to the mature cabbage.
It's worth mentioning these results, while exciting, come from an animal study. Human physiology is similar but not identical, and we'd love to see clinical trials in people.
How to use red cabbage microgreens
Incorporating red cabbage microgreens into your diet is simple and enjoyable:
-
Salads: Toss a handful of red cabbage microgreens into your salads. They will add a pop of color (beautiful purplish stems and green leaves) and a mild cabbagey crunch. You can use them in place of or in addition to lettuce. Pairing them with a spinach or mixed green salad works great.
-
Sandwiches and wraps: Use microgreens as a more nutritious substitute for lettuce on sandwiches and burgers. Red cabbage microgreens bring a slight red cabbage flavor (imagine the taste of coleslaw, but very delicate). They go well on turkey or chicken sandwiches, veggie wraps, or even alongside avocado in toast.
-
Smoothies: Yes, you can blend microgreens into smoothies! If you're feeling adventurous, a small handful of red cabbage microgreens can go into a berry smoothie. The berries and yogurt will dominate the flavor, while you sneak in the extra polyphenols. The smoothie might turn a slightly earthy color, but the taste will remain fruity.
-
Garnish soups and stir-fries: While you wouldn't want to cook microgreens for long (they're tender), you can certainly top a soup or stir-fry with them right before serving. Imagine a hearty vegetable soup or even a bowl of chili - sprinkling red cabbage microgreens on top not only looks appealing but adds those raw antioxidants that might otherwise be lacking in a cooked dish. Same with stir-fry: after plating, top with a bunch of microgreens for a fresh contrast.
-
Tacos and bowls: Use in place of shredded cabbage on fish tacos or burrito bowls. They provide that cruciferous bite in a convenient form. For instance, on a fish taco you might normally put slaw - try a handful of microgreens with a squeeze of lime as an impromptu slaw replacement.
Grow your own microgreens
One of the best aspects of microgreens is how easy it is to grow them at home, even with minimal space. Red cabbage microgreens in particular are beginner-friendly. You can grow them on a sunny windowsill or under a basic LED light. Sprinkle Deliseeds Red Cabbage Microgreen Seeds on a tray with soil, keep them misted with water, and in about 10 days you'll be harvesting your very own garnishes. Home-grown microgreens are extremely fresh and potent. Plus, you'll have a continuous supply if you sow new seeds every week or so.
Growing your own also ensures you have a clean source (important if you're aiming to maximize raw consumption for those delicate nutrients). It's quite cost-effective as well - a packet of seeds can produce several batches of microgreens, far cheaper than buying equivalent fancy salad mixes repeatedly.
Small greens, big benefits
While we await more human research, incorporating red cabbage microgreens into a balanced diet is a safe, smart move. There's virtually no downside - they're low in calories, high in good nutrients, and easy to add to foods you already enjoy. They can help tilt your diet towards more plant-based goodness without drastic changes.
So, whether you grow them on your windowsill or pick them up at a local market, give these greens a try. Sprinkle them daily as a reminder that powerful nutrition can come in small packages.
