Radish is loved by many people for its crunch. But did you know that radish benefits your health? Radishes (Raphanus raphanistrum subsp. sativus) are loaded with many beneficial nutrients. They are a rich source of vitamin C, an antioxidant that combats free radical damage (1). Additionally, potassium, magnesium, folate, calcium, and riboflavin are also present in these root vegetables.

Sulforaphane is an antioxidant found in radish. It is a type of isothiocyanate that can potentially inhibit certain types of cancer (2).

The accumulation of bilirubin in the body causes jaundice (3). Consumption of radish decreases the levels of bilirubin. Also, the indoles present in this vegetable are known for their anticancer properties (4).

Radish is a powerful vegetable with many unique nutrients. We have seen some of them in this section. But are radishes good for you? If yes, what are their health benefits?

Health Benefits Of Radishes

Isothiocyanates are the most powerful compounds in radishes. These antioxidants promote heart health and help combat cancer. While these antioxidants may also aid diabetes treatment, the fiber in radishes may promote digestive health and weight loss.

1. May Improve Cardiovascular Health

Extracts of radishes were found to influence nitric oxide production in rat studies. This causes the blood vessels to relax and can lower blood pressure eventually (5). Monster radish, also called Sakurajima daikon that is cultivated in Japan, was also found to have similar properties (6).

Nitric oxide also plays a role in relaxing the smooth muscle tissue and increasing the regional blood flow. It also inhibits platelet adhesion to the blood vessel walls. All these benefits can help reduce the risk of atherosclerosis (7).

2. May Lower Cancer Risk

Radishes belong to the family of cruciferous vegetables. These vegetables contain compounds that are broken down into isothiocyanates when combined with water (8). These isothiocyanates may help combat different forms of cancer.

The isothiocyanates in radish seeds were also found to induce cell death in lung cancer cells (9).

Radish was also found to exhibit chemopreventive effects in the case of breast cancer. In addition, it could directly inhibit the growth of cancer cells and induce cancer cell death. Hence, it can be a useful antitumor agent and play a role in cancer treatment and prevention (10).

These preventive effects of radish on breast cancer can be attributed to its sulforaphane content (11).

3. May Aid Diabetes Treatment

Radishes have antidiabetic effects. They strengthen the antioxidant defense system of the body and reduce the accumulation of free radicals. This promotes energy metabolism and reduces glucose absorption in the intestine, thereby helping individuals with diabetes (12).

4. May Promote Digestive Health

Radishes are good sources of fiber and may enhance digestive health. The same holds for the leaves of the vegetable. Rats fed with radish leaves showed enhanced gastrointestinal function (13).

Radish has been used ethnically as an aid for digestion, stimulant, laxative, and treatment for stomach disorders(3).

5. May Aid Weight Loss

Although we don’t have any direct research linking radishes to weight loss, the fiber in these veggies may help with weight loss. In addition, studies show that a high-fiber diet could be very beneficial for weight management (14).

Radishes are also low in calories. One large radish contains about 6 calories (15). Hence, they can be an excellent addition to a weight loss diet.

6. May Treat Kidney Stones

A diet containing radish was found to increase the excretion of calcium oxalate through urine (16). This could decrease the likelihood of the minerals getting accumulated inside the urinary tract and forming stones.

However, more research is warranted in this regard. Consult with your doctor before using radishes specifically to treat kidney stones.

7. May Help Prevent Osteoarthritis

The sulforaphane in cruciferous vegetables, including radish, can be beneficial for osteoarthritis (17). The compound works by preventing cartilage destruction in cells. More research is needed to understand the mechanism of radish in the treatment and potential prevention of osteoarthritis.

8. May Promote Liver Health

Cruciferous vegetables, including radish, can aid the detoxification of toxins in the liver. Studies show the liver-promoting effects of Spanish radish, a prominent radish type. The radish contains high concentrations of glucosinolates, which help promote liver health (18).

Radish is used as a household treatment for jaundice and other related liver diseases in Indian and Greeko-Arab folk medicine (12).

In another study, a bioactive chemical in radish (called MTBITC) was found to be effective in treating non-alcoholic fatty liver disease (19).

Though radish is among the healthiest vegetables, not everyone can consume it. In addition, there are a few concerns associated with the vegetable.

What Are The Side Effects Of Radishes?

Although radishes have benefits, there are some cases where side effects of eating radishes have been reported. People with low levels of blood sugar and thyroid hormone can face some adverse effects.

  • May Aggravate Hypothyroidism

Cruciferous vegetables, like radish, contain goitrogenic substances that may interfere with the production of the thyroid hormone. As per studies, chronic radish feeding can lead to reduced thyroid hormone profiles (20). Individuals with thyroid issues (especially hypothyroidism) must limit their consumption of radishes and other cruciferous vegetables.

  • May Increase Risk Of Gallstones

Radishes are known to increase bile secretion (21). Some believe this property may increase the risk of gallstones in susceptible individuals. Though more research is needed, it is important to take precautions. If you have a history of gallstones, please consult your doctor before consuming radishes.

  • May Aggravate Hypoglycemia

Radish can lower the levels of sugar in the blood. It has hypoglycemic effects (12). Those already on medications for diabetes may need to check with their doctor before taking radish, as it may lower blood sugar levels way too much.

  • Issues During Pregnancy and Breastfeeding

There is not much evidence to establish that radish is safe to use while pregnant or breastfeeding. It is safer to avoid or consume radish in moderation. Please consult your doctor.

  • Food Allergies

Radish allergy is relatively uncommon. However, it may trigger various symptoms, typically involving skin issues like itching or hives, along with gastrointestinal problems, such as nausea or diarrhea (22). Severe cases may lead to anaphylaxis, a condition characterized by difficulty in breathing and a drop in blood pressure (23). People with known allergies related to foods, like cruciferous vegetables (broccoli, cabbage, kale, etc.), may be at a higher risk of being allergic to radishes.

If you suspect a radish allergy, seeking medical advice from your healthcare provider for proper diagnosis and guidance is important. As a preventive measure, avoid consuming radishes and related foods, especially for those with confirmed allergies.
