The Hydrating, Detoxifying, Heart-Healthy Power of Radish Nutrition

Chances are you’ve eaten a radish before, but radishes are often overlooked ingredients in salads, side dishes and even main courses. Well, it’s high time for the radish to get its due because radish nutrition offers a plethora of health benefits.

For instance, the radish is an alkaline-forming food , which is very helpful in keeping pH balance in check. (1) What else can radish nutrition do? Read on for to learn the remarkable health benefits of radishes and the role radish nutrition can play in a healthy diet.

What Is the Radish?

Radishes are members of the Brassicaceae family, which also includes mustard and cabbage. The root of the radish is related to kale, broccoli, cauliflower and horseradish, to name a few. (2)

The radish is known as a classic adornment for the leafy green salad, offering a crunchy, peppery punch, but has actually been around for a very long time. Most states grow radishes, with Florida and California topping the growth charts.

The name origin of the radish is from the Latin word radix, and its genus name is Raphanus coming from of an ancient Greek expression raphanos, meaning “easily reared.” The radish is usually seen pickled in brine, much like you see pickled cucumbers, in places like China and Japan, with nearly one third of the weight of vegetables grown in Japan being the daikon radish.

When pickled or fermented, the radish gains a beautiful yellow color that actually seems unattractive to many in the U.S. but is delicious and nutrition-packed. Regardless, it’s part of the core diet in Japan, adding a zip to the commonly consumed bowls of rice.

You’re probably familiar with the white, red, or red and white radish. Some grow the round black Spanish or long black Spanish varieties, which contain a black skin and have a bright white flesh that’s firm and crisp. There are also the rose-colored China rose and shite Strasburg, which are a part of what’s known as winter radishes and are usually stored similar to beets and turnips.

Health Benefits

1. Jaundice and Detoxification Treatment

The radish is may be a perfect natural remedy for jaundice. While jaundice is usually thought of as only occurring in infants, it can actually occur in adults. If you notice a yellowish discoloration of the skin, mucous membranes and white of the eyes, you may want an evaluation by your doctor. This could be the result higher than normal levels of bilirubin in the blood, and though it’s not a disease, it could be an indication of something more serious.

The radish fits in due to its detoxification properties helping to cleanse the blood of toxins and waste. The radish seems capable of removing bilirubin, which stabilizes production. Using the black radish and the radish leaves has been known to do the best job at detoxification — however, I don’t recommend the radish for infants without the approval from a doctor. (4, 5)

2. Osteoarthritis Relief

Vitamin C is essential to making collagen, which is part of what makes up the much-needed cartilage in our bodies. When we think of vitamin C, we often have a vision of oranges and orange juice, but did you know that radishes are actually some of the top vitamin C foods? Radishes provide 17.2 milligrams per serving, which is about 29 percent of your daily requirement.

Vitamin C is an antioxidant that can help limit damage to cartilage that may be caused by free radicals found in the body. Ultimately, this can help anyone who has been diagnosed with arthritis as well as prevent it in the first place. (6)

3. Weight Management

Radishes are typically small but pack a good bit of fiber, offering a fulfilling addition to your plate. As a high-fiber food, radishes can help regulate bowel movements, eliminate constipation, which is a cause of hemorrhoids, and may help lower cholesterol by binding to low-density lipoproteins.(7)

Because fiber does not digest easily, eating fiber-rich foods can help you feel full, helping you achieve satiety and avoid overeating. Most adults don’t get enough fiber in their diets. On top if that, the radish is very low in calories and contains a lot of water, which makes them a great option for most any meal and useful for anyone trying to lose weight.

4. Heart Health

Radishes may help reduce incidence of heart disease. Much like red cabbage, radish nutrition contains a type of flavonoid called anthocyanins, the same flavonoid you find in blueberries.

According to a recent study, these anthocyanins possess anti-inflammatory properties that can help reduce the risk of cardiovascular disease and its effects such as peripheral artery disease, heart failure and even kidney disease. The anthocyanins are able to circulate metabolites, which are the “products of metabolic reactions catalyzed by various enzymes” naturally occurring within cells.

This process could be what provides protection against many heart issues, targeting the vascular system, by reducing oxidative stress and reducing inflammation. (8)

5. Skin Health

The radish contains many nutrients, such as B vitamins, zinc, phosphorus and vitamin C, which can help the skin heal. Additionally, radish nutrition contains water, as I noted above, providing much-needed hydration for the skin.

Part of what makes the radish a good choice for the skin is the antibacterial properties that help heal dry, cracked skin and prevent infection. (9)

Recipes

Pickling is a great way to preserve food, add spice or a nice zing to almost any dish and to get some beneficial probiotics. For those who don’t enjoy the peppery zing of raw radishes, pickling may be the way to go. Additionally, you can add health-giving herbs and spices, such as mustard, garlic, dill and turmeric — almost anything goes.

Radish Interesting Facts

The radish is grown for many reasons, such as cooking and for the oil contained within its seeds. India grows the rat-tailed radish variety for the fleshy seed pods, while Egypt desires the tops for greens. Radishes can be as small as a grape tomato or as big as a basketball, and the long varieties can get up to two feet long!

The radish is believed to have originated in China due to the wild varieties that have been found there, with Middle Asia noted as developing many forms after the introduction from China in prehistoric times.

Records show that radishes were very common in Ancient Egypt, even before the pyramids were built. Replicas of the radish were created in gold with beets in silver and turnips presented in lead. Ancient Greeks have written much about radishes as well as the Romans.

Larger varieties were mostly noted in northern Europe and England with a report in 1544 by a German botanist of a radish weighing in at 100 pounds! The radish became popular in Mexico around the 1500s, Haiti in 1565 and England in 1586, possibly making them one of the first European crops brought over by Columbus.

Risks and Allergies

Radishes are safe to eat for most people. However, if you develop a rash or an allergic reaction, stop eating immediately.

Eating large amounts of radish may irritate the digestive tract as well. There have not been any reports of problems associated with pregnancy and breast-feeding, but take caution if you feel it’s necessary.

Radishes may irritate anyone who has gallstones, so it may be best to avoid.

Final Thoughts

The radish can be a great addition to most any diet. Eat in small amounts and you should be able to gain the wonderful benefits of radish nutrition while enjoying a spicy punch to most any meal. For instance, radishes can help with detoxification, arthritis relief, weight management, and heart and skin health.

For anyone who is not fond of the radish but wants to the benefits, consider the recipes above or thinly shave them onto a salad. The smaller pieces may be less noticeable and more enjoyable to eat, allowing you to obtain all the wonders of radish nutrition.
