How Many Calories Are In Radishes? | Quick Calorie Facts

Radish Calories By Serving Size

Radishes are crisp, peppery, and low in energy. Most servings land in the teens. A cup of sliced red radish comes in at about 19 calories, while 100 grams sits near 16. Both figures come from lab-based data compiled by MyFoodData, which draws from USDA analyses.

Serving	Approx. weight	Calories
1 medium radish	5 g	~1
1 large radish	9 g	~1–2
1 slice	1 g	~0
1 cup sliced (red)	116 g	~19
1/2 cup sliced	58 g	~9
100 g (raw)	—	~16
1 oz (raw)	28 g	~5
1 cup sliced daikon	116 g	~21
1 cup radish sprouts	38 g	~16

The “medium” size here is the familiar round salad radish, about three-quarters to one inch across. A single medium piece weighs around 5 grams and contributes only about one calorie. The cup figure uses sliced pieces settled in a measuring cup, not packed. Data points reflect standard reference entries from MyFoodData and linked USDA records.

Calories In Radishes Per Serving: Sizes And Prep

When you scan a label or a nutrition table, two lines matter for planning: calories per 100 g and calories per cup. These cover both metric cooking and home scooping. Red radishes usually sit near 16 kcal per 100 g and about 19 kcal per cup sliced.

Per 100 Grams Vs Per Cup

Per 100 g is the cleanest way to compare produce. With radishes, that line reads ~16 kcal, ~3.4 g carbs, and ~1.9 g fiber for a cup. The cup entry (116 g) reads ~19 kcal, as the cup contains slightly more than 100 g. These values come from the same database entry, so they stay consistent across charts.

How Daikon Compares

Daikon, the long white “oriental” type, is also lean. A cup of sliced raw daikon shows about 21 calories, while a cup cooked in water lands near 25, mostly due to water weight and serving size differences.

Do Different Radishes Change The Count?

Color and shape vary, yet energy density barely moves. Red globe, watermelon, French breakfast, and white icicle types cluster in the same range. Expect something close to the mid-teens per 100 g. Daikon skews a touch higher per cup because cup weights differ, not because the root suddenly becomes dense.

What About A Handful?

Ten medium red radishes weigh roughly half a cup and still sit under 20 calories. That makes a crunchy snack that pairs well with lemon, herbs, and a pinch of salt. If you reach for dips or butter, count those add-ons, not just the veg.

Cooking Methods And Real Calorie Changes

Heat changes texture and flavor more than energy. Roasting dries the surface and brings out mild sweetness. Boiling softens the bite. The root itself stays low; the main swing comes from oil, butter, or sugary brines.

Roasting

One teaspoon of oil adds about 40 calories to the pan. Toss a tray of halved radishes with a teaspoon or two, roast hot until tender, and you still end up with a side that fits into a light meal. The root brings the crunch; the fat brings most of the energy.

Boiling Or Sautéing

A cup of boiled daikon reads around 25 calories, while the raw cup lists about 21. The difference is small in daily totals. Sautéing with oil moves things more, due to the oil.

Carbs, Fiber, And Net Carbs

Radishes are mostly water. The cup entry for red radish shows about 3.9 g carbs, with about 1.9 g fiber. Net carbs per cup stay low. That is why radishes fit salad bowls, taco plates, and snack trays without pushing totals. Numbers in this paragraph come from lab-compiled sheets you can view on MyFoodData.

Smart Ways To Count Radish Portions

Kitchen scales make tracking easy, yet plenty of cooks use visual cues. Here are simple swaps that keep you close to the tables above.

Quick Visuals

• Five to six medium radishes ≈ 30 g to 35 g.
• Half a cup sliced ≈ a loose handful of thin rounds.
• One packed taco topping layer ≈ 25 g to 40 g, depending on slice thickness.

These visuals keep energy budgets simple. If you like numbers, weigh a handful once, note your usual slice style, and reuse that cue next time.

Flavor Boosters That Change Calories

Seasonings like salt, pepper, lime, chili flakes, and herbs add almost nothing. Creamy dips, oils, and cheeses move the needle. The table below shows common pairings with a typical portion and extra energy to log.

Add-in	Typical portion	Extra calories
Olive oil	1 tsp	+40
Butter	1 tsp	+34
Ranch dip	2 Tbsp	+120
Cream cheese	1 Tbsp	+50
Greek yogurt dip	2 Tbsp	+35–45
Quick pickle brine	2 Tbsp liquid	+10–20 (if sugared)

Keep the root the star, and those extras stay in check. A splash of vinegar, a squeeze of citrus, or a dusting of smoked paprika gives punch with minimal energy.

Nutrients You Get Along With Those Few Calories

That small cup brings vitamin C and potassium, plus a little folate and magnesium. The raw cup entry shows about 17 mg of vitamin C and around 270 mg of potassium. Crisp texture and a peppery kick help replace heavy toppings on tacos and bowls, which can lower the total energy of the whole plate. Values here match the raw cup line in the reference sheet.

Radish Types, From Salad Rounds To Daikon

Red globe radishes are common in salads. Daikon turns up in soups, stir-fries, and pickles. Both are light. Raw daikon comes in at about 21 calories per cup, while the red round sits near 19. The slight gap doesn’t change meal planning much, yet it can explain why two cups that look the same on the table don’t show the exact same line in an app.

Pickles And Ferments

Quick pickles add sugar unless you choose a no-sugar brine. Fermented styles vary. If the jar lists added sugar, count it. Check labels and log the portion of the liquid if you spoon it over a dish.

Ideas Under 100 Calories

• One cup sliced red radish with lime and flaky salt (~19 kcal).
• Roasted radish halves with 1 tsp olive oil for the tray (~40 kcal added; split four ways stays tiny).
• Daikon matchsticks tossed with rice vinegar, sesame seeds, and scallion (brine without sugar keeps energy low).

Shopping, Storage, And Prep Tips

Look for firm roots and crisp greens. Trim greens soon after buying and store roots in a bag in the fridge. USDA’s SNAP-Ed seasonal page lists radishes as a spring and fall pick and suggests quick roasting for a milder bite. That page is handy if you’re planning weekly produce. SNAP-Ed radishes.

Key Takeaways For Meal Planning

What To Log Fast

• Red radish, cup sliced (116 g) → ~19 kcal.
• 100 g raw radish → ~16 kcal.
• Daikon, cup sliced → ~21 kcal; boiled cup → ~25 kcal.

Where Calories Creep In

• Oil on the tray or pan.
• Creamy dips and spreads.
• Sugary brines in pickles.

Lean roots plus bold, low-energy seasonings give you crunch and color with minimal math. When you do add richer sides, measure once and reuse that portion cue next time. You’ll get the same flavor hit without guesswork.
