Health Benefits

Overview

Red radishes are packed with nutrients like Vitamins E, A, C, B6, and K.  They are also a good source of zinc, potassium, phosphorous, magnesium, copper, calcium, iron and manganese.  

Antioxidants to Prevent Disease

Radishes are also a good source of anthocyanins. These flavonoids not only give radishes their red color, but they also help promote the health of your heart.

These compounds fight free radicals to prevent the development of tumors and protect against various forms of cancer.

Their natural sulphur content also acts as an antioxidant and is associated with many health benefits, such as the prevention of hypothyroidism.  The organic sulphur found in cruciferous veggies, like radishes also have anti-inflammatory properties.

Detoxifies the Blood

Radishes are an amazing detoxifier of the liver.  They also help purify the blood and increase the supply of oxygen to the blood.  In fact, radishes and radish leaves (greens) are even used as a natural treatment for jaundice.

Promotes Healthy Skin

The vitamin C in radishes, along with zinc and phosphorus can help improve the skin.  Eating radishes and applying them topically to the skin can help prevent dryness, acne and even treat rashes.  Their high content of water also provides hydration and moisture to the skin.  You can even make your own natural face mask using pureed raw radishes.

Improves Hydration

Because of their high water content, radishes help keep your body hydrated. Proper hydration is vital to good health as it boosts energy and mood.  Drinking enough water can be challenging, so it’s important to eat hydrating foods like radishes to help balance fluid levels and flush out toxins from the body.  Fruits and veggies with high water content can also help prevent kidney infections.

Supports Healthy Digestion

Radishes are packed with roughage and fiber, so they’ll help keep your digestive system moving. Foods containing fiber also improve blood sugar response.

Lowers Blood Pressure

Radishes are quite high in potassium, which lowers blood pressure and supports the production of collagen necessary to keep blood vessels healthy. Radishes also help control damage to red blood cells and help increase oxygen supply to the blood.

Improves Metabolism and Strengthens the Immune System

A half-cup of radishes offers 15% of your daily intake of vitamin C. Vitamin C has been shown to boost immunity and regulate metabolism.

Side Effects

Radish is likely safe for most people when taken in moderate amounts. Taking large amounts of radish can irritate the digestive tract.  Allergies to radishes are rare.
