Radish Nutrition

According to USDA, radish is rich in various nutrients that include potassium, calcium, sodium, and vitamin C. It contains vitamins like thiamin, niacin, riboflavin, folate, and vitamin B6, A and K. It also provides iron magnesium, phosphorus, and zinc.

Health Benefits of Radish

The benefits of radishes in the treatment or prevention of certain ailments and on certain body parts are listed below:

Treats Jaundice

Radishes are very good for the liver and stomach, and they act as a powerful detoxifier too. They purify the blood and eliminate toxins and waste. Research also suggests that they are extremely useful in treating jaundice because they remove bilirubin and keep their production at a stable level. Radishes reduce the destruction of red blood cells that occurs in people suffering from jaundice by increasing the supply of fresh oxygen to the blood. Black radishes are more preferred in the treatment of jaundice, and radish leaves are also very useful for the same.

Boosts Immunity

There are countless reasons why radishes are a good addition to your diet, but improving your immune system is one of the most important benefits. A half cup of radishes per day in a salad or just as a snack is nearly 15% of your daily intake of vitamin C. Consistently maxing out your daily dose of vitamin C intake can rejuvenate your immune system by replacing many of the antioxidants and white blood cells which are integral in fighting off every illness from the common cold to cancer!

Vitamin C not only boosts your immune system but is also considered a super vitamin because of all the high-impact effects it has on the body. It helps regulate your metabolism, which changes fat into usable energy, and it is the main contributor to the creation of collagen, an essential protein that strengthens blood vessel walls and reduces the chances of atherosclerosis and heart diseases.

Aids in Digestion

Radishes are rich in fiber that adds considerable bulk to bowel movements, which promotes regular excretory patterns and relieves the symptoms of constipation. A 2008 study suggests that radish leaves can also help firm up loose bowels and get rid of loose stool or diarrhea. Furthermore, radishes are known to promote the production of bile. Bile is one of the most important parts of good digestion, and also helps to protect both the liver and gallbladder.

Prevents Piles

Radishes are considered to have roughage, which means that they are composed of indigestible carbohydrates. This facilitates digestion, water retention, and fixes constipation, which is one of the major causes of piles. As a good detoxifier, they help heal the symptoms of piles very quickly. Radish juice also soothes the digestive and excretory system, further relieving the symptoms of piles.

Cancer Prevention

Since radishes are detoxifiers and are rich in vitamin C, folic acid, and anthocyanins, they have been connected to treating many types of cancer, particularly colon, kidney, intestinal, stomach, and oral cancer. Research on the anti-cancer potential of radishes suggests that as they are part of the Brassica family, these cruciferous vegetables are packed with antioxidants that have chemopreventive properties.

Furthermore, the isothiocyanates found in radishes have a major impact on the genetic pathways of cancerous cells. They alter the pathways so much, that they can cause apoptosis (cell death) thereby eliminating cancerous cells from reproducing.

Urinary Disorders

Radishes are diuretic in nature, which means that they increase the production of urine. Radish juice also helps reduce inflammation and the burning sensation during urination. It cleans out the kidneys and inhibits infections in the kidneys and urinary system, thus helping the treatment of various urinary conditions that are exacerbated by excess toxins in the system.

A 2012 study revealed that radish has antifungal properties. It can help induce cell death in a common fungus known as Candida albicans, which can cause oral infections and vaginal yeast infections.

Weight Loss

Radishes are very filling, which mean that they satisfy your hunger without running up the calorie count. They are also low in digestible carbohydrates, high in roughage, and contain a lot of water, thus becoming a very good dietary option for those who are determined to lose weight. Furthermore, they are high in fiber and low on the glycemic index (GI), which means that they regulate bowel movements, thereby helping in weight loss and increasing the efficiency of metabolism.

Improves Cardiovascular System

Radishes are a great source of anthocyanins, a flavonoid, which not only give color to radishes but also provide numerous health benefits. Anthocyanins have been the subject of numerous medical studies, and have been positively linked to reducing the occurrence of cardiovascular diseases. They have also displayed anti-cancer and anti-inflammatory properties.


The detoxifying and anti-carcinogenic properties of radishes make them useful in the treatment of leucoderma and radish seeds are used in this method. They should be powdered and soaked in vinegar, ginger juice, or cows urine and then applied on the white patches. You can eat radishes as well to aid in the treatment of leucoderma.

Relieves Respiratory Disorders

Radishes are an anti-congestive, meaning that they decrease congestion of the respiratory system including irritation of the nose, throat, windpipe, and lungs that can come from colds, infections, allergies, and other causes. They are a great disinfectant and are rich in vitamins, which further protects the respiratory system from infections.

Radishes have a strong, natural spice to them, and they are also quite pungent, which is very good for preventing illnesses. They also eliminate excess mucus in the throat. Furthermore, radishes have been known to soothe sore throats and relieve congestion by clearing the sinuses.

Lowers Blood Pressure

Radishes are a very good source of potassium, which contributes to a large list of health benefits. Dr. Haddy, Department of Physiology and Biomedical Engineering, Mayo Clinic, College of Medicine, Minnesota, USA, suggests that potassium helps in reducing blood pressure. This is because when it interacts with the arterial supply of vascular beds, it can relax the blood vessels, and therefore promote blood flow. It also reduces the blood pressure by widening the flow of the blood, instead of forcing it through narrow, constricted channels.

Manages Diabetes

Radishes have long been known to have a low glycemic index, which means that eating a radish does not impact blood sugar levels. Also, a study published in 2017 states that drinking radish root juice has a positive effect on the blood glucose levels of diabetics. They also help regulate the absorption of sugar into the bloodstream, meaning that diabetics don’t have to worry as much about sudden spikes or drops when eating or being away from food for a certain amount of time.

Skin Care

Vitamin C, phosphorus, zinc, and some members of the vitamin-B complex, present in radishes are good for the skin. The water in radishes also helps to maintain healthy moisture levels in the skin. Smashed raw radish is a good cleanser and serves as an efficient face pack. Due to its disinfectant properties, radishes also help clear up skin disorders like dry skin, rashes, and cracks.

Reduces Fever

Radishes lower body temperature and relieve inflammation from fevers. A good method of intake is drinking radish juice mixed with black salt, and since they act as good disinfectants, radishes also fight infections that can cause fever.

Protects Kidneys

As a diuretic, cleanser, and disinfectant, radishes help in the treatment of many kidney disorders. The diuretic properties help wash away toxins accumulated in the kidneys and decrease the toxins in the blood. Their disinfectant properties protect the kidneys from any infections as well.

Insect Bites

Radishes have anti-pruritic properties and can be used as an effective treatment for insect bites and bee stings. Radish juice also reduces pain and swelling and soothes the affected area.

Keeps you Hydrated

Radishes are mostly composed of water, and they are a great way to keep your body hydrated, which is very beneficial for your health. One of the most important parts of staying hydrated is the impact of water on the digestive system. Staying hydrated relieves constipation, improves digestion, and ensures proper uptake of nutrients from the food we eat.

Protects Liver & Gallbladder

Radishes are especially beneficial for liver and gallbladder functions. Several studies have been conducted on determining the impact of radish on the liver. One such study published in 2012 suggests that white radish enzyme extracts help protect you against hepatotoxicity.

They regulate the production and flow of bile and bilirubin, acids, and enzymes. Furthermore, they also remove excess bilirubin from the blood and contain enzymes like myrosinase, diastase, amylase, and esterase. Regular consumption of radishes protects your liver and gallbladder from infections and ulcers and aids in treating gallstones.

Other Benefits

Apart from the benefits outlined above, radishes work as a good appetizer, mouth and breath freshener, laxative, and metabolism regulator. People who supplement their diet with a normal amount of radishes see an improvement in blood circulation, and radishes are a good treatment for headaches, acidity, constipation, nausea, obesity, sore throat, whooping cough, gastric problems, and dyspepsia. Due to the presence of niacin, it also helps prevent pellagra.

Finding it hard to digest everything you just read? Well, I suggest you have some slices of radish to get your stomach working properly, and perhaps make you hungry for even more nutrient-packed power food!
