- New research suggests that radish greens may offer significant gut health benefits because of their high levels of polyphenols and flavonoids, which support antioxidant activity.
- These leafy tops also contain beneficial polysaccharides, such as rhamnogalacturonan, which may promote a healthy gut microbiome and even help reduce cold symptoms.
- While most studies so far are preclinical, the consistent results indicate that radish greens have potential as functional food supplements — or as a nutritious addition to your next meal.
Looking to improve your gut health? It may be time to eat more radishes — just not the part you might expect.
In September 2025, researchers published a comprehensive review of a growing body of research on the potential health benefits of radish greens, the leafy tops typically trimmed off and discarded before the rest of the vegetable reaches your plate. As the review, published in the Journal of Agricultural and Food Chemistry, found, these greens may offer the human body many benefits, particularly for gut health.
According to the study’s abstract, while radish roots have been widely studied for their vitamin and mineral content, the leaves have received far less attention. However, it’s their time in the limelight, as the studies these researchers analyzed found. Radish greens consistently contain higher concentrations of polyphenols and flavonoids than the root itself.
Polyphenols and flavonoids are critical to human well-being because these naturally occurring plant compounds are well known for their antioxidant activity, which helps neutralize free radicals in the body, agents that can cause inflammation and cell damage over time. As study after study has shown, diets rich in these compounds are associated with improved health outcomes, including better digestive and metabolic function.
The radish review also highlighted another promising component in radish leaves: polysaccharides. Polysaccharides, the Sugar Nutrition Research Center explained, are “one of the most abundant carbohydrates” humans consume. The center added that these polysaccharides play a “range of roles in the human body,” from energy storage to serving as cellular messengers. They also act as dietary fiber, which “helps to maintain our digestive tracts in good working order” and keeps things moving through the body and out of it.
The researchers identified a particularly beneficial polysaccharide, rhamnogalacturonan, in the greens, which has been shown to stabilize the gut microbiome and may also reduce cold symptoms as a secondary benefit.
The easiest ways to use radish greens
Don’t toss those leafy tops. Radish greens have a peppery, slightly bitter flavor similar to arugula or mustard greens and can be used anywhere you’d cook tender leafy greens.
- Sauté with olive oil, garlic, and a pinch of salt, then finish with lemon
- Blend into pesto, chimichurri, or green sauces
- Stir into soups, stews, or curries at the end of cooking
- Add raw, finely chopped, to salads or grain bowls for a sharp, fresh bite
Tip: Younger, smaller greens tend to be more tender and less bitter, while larger leaves can be tough and are best served cooked.
It is important to note that the studies the researchers drew on were largely preclinical, meaning they weren’t conducted on humans or in a lab setting. However, they noted that the consistency of their findings is compelling, particularly given the potential to turn radish greens into functional supplements. But until that day comes, you could always try to start incorporating those greens into your meals. We even have a recipe to help you get started.
