vs
Daikon

Summary

Radishes are rich in minerals, vitamins, protein, polyunsaturated fat and have fewer sugars than daikons. On the other hand, daikons contain more carbs, lower in calories, saturated fats, and sodium than radishes.

Introduction

Daikon and radish are widely used in cooking, but people often confuse these two vegetables. We are going to identify their differences by focusing on their nutritional value. The main difference between a daikon and a radish is that a daikon is a winter radish, and it looks more like a long, white carrot. Besides, daikons are sweeter, juicier, and less spicy than radishes.

Actual differences

Varieties

Daikon is also known as mooli and belongs to the Raphanus genus. It is a winter radish that is usually characterized by long white roots and fast-growing leaves. There are many different types of daikon, of which the most common types are Watermelon Radish, French Breakfast Radish, and Daikon White Radish.

Radish also belongs to the Raphanus genus; it is an edible root vegetable of the family Brassicaceae consumed worldwide. The most common varieties of radish are Watermelon Radish and Pink Radish.

Taste and Use

Overall, radishes have a peppery flavor; sometimes, the taste tends to be milder depending on how long they were left on the earth to grow. Radishes are often eaten raw or added as a flavor in a salad. Daikon radishes are sweeter than radishes. They can be eaten raw or cooked. The greens from daikon are also edible.

Nutrition

Glycemic Index

Both radishes and daikons are considered low glycemic index products. Moreover, both vegetables have an equal GI. The GI of raw daikons and radishes is 32.

Acidity

The average PH value of radishes falls in the range of 6.0-7.0, whereas the PH value of daikon is equal to 7.5. Daikon is more alkaline than radish. Another way to assess the acidity of foods is the potential renal acid load. The PRAL value of food shows how much acid or alkali a given food produces when broken down in the body.

The PRAL values of daikon and radish are -4.4. These vegetables in the body are more alkaline.

Health Impact

The nutritional values are presented for raw daikons and raw radishes. At the bottom of this page, you can find nutrition infographics of these vegetables.

Cardiovascular Health

Daikon and radish are highly nutritious vegetables, rich in potent plant compounds, vitamins, minerals, and fiber, which together protect your body from disease. Vegetable consumption has been linked to a lower risk of heart and other chronic diseases.

Radishes are excellent sources of antioxidants and minerals like calcium and potassium, which may help to lower high blood pressure and lower the risk of heart disease. These vegetables are also rich in natural nitrates that improve blood flow [1].

Diabetes

Radishes are low-calorie, high-fiber vegetables. They contain chemical compounds such as glucosinolate and isothiocyanate that help regulate blood sugar levels. Eating radishes also increases the body's natural production of adiponectin. Higher levels of this hormone can help protect against insulin resistance. Radishes also contain coenzyme Q10, an antioxidant that helps block the formation of diabetes [2].

Weight Loss and Diets

Eating low-calorie and high-fiber foods can help you maintain a healthy weight or lose weight. Radishes and daikons have almost a similar number of calories.

They both are considered non-starchy vegetables, which means they are deficient in carbs. According to studies, eating non-starchy vegetables can promote a healthy body weight [3].

Cancer

Eating cruciferous vegetables such as radishes can help prevent cancer. Both radishes and daikons contain phytochemicals and anthocyanins, which have anti-carcinogenic properties. They are rich in sulforaphane, which research has shown to fight breast, colon, prostate, and ovarian cancers. Moreover, vitamin C acts as a powerful antioxidant, preventing free radicals from damaging DNA inside cells, thereby helping to prevent cancer. According to the study, radish root extract contains several isothiocyanates that cause cell death in some cancer cell lines [4].

Boost Immune System

Vitamin C can boost immune defenses by supporting various cellular functions. One hundred grams of daikon contains 22 mg of vitamin C, 30% of the recommended daily intake. Vitamin C is mainly concentrated in plant leaves. Daikon leaves are richer in vitamin C than oranges. Raw daikon juice can help dissolve mucus and phlegm and promote healthy respiratory function [5].

Detoxification

The natural diuretic property of radishes makes them highly beneficial to kidney health. They help flush out toxins from the body and act as a natural cleanser, preventing the buildup of waste products in the kidneys.

Daikon glucosinolates effectively enhance detoxification enzymes and, therefore, may have significant chemopreventive activity [6].

Side Effects

Daikons and radishes are presumed to be relatively safe vegetables; however, they might not be suitable for those suffering from gallstones. Both are goitrogenic foods. People with impaired thyroid function can minimize the risk of adverse effects by cooking them and increasing their selenium intake [7].
