Radish calories come to 19 for 1 cup sliced (116 g) and 16 per 100 g of raw red radish. That cup is just 1% of a daily calorie budget. The thing to notice: carbs supply 79% of those few calories, and 1.6 g of fiber per 100 g is a large share for so little energy.

Five cups of sliced radish add up to 93 calories
A single medium radish weighs about 4.5 g and carries roughly 1 calorie. You need a full cup of slices, 116 g, to reach 19 calories, and half a cup (58 g) lands at 9. Few foods on a calorie page post numbers this small, and they barely register in a day of eating.
Scaling up shows how little changes. Two cups sliced (232 g) come to 37 calories, three cups (348 g) to 56, and five cups (580 g) to 93. Even that big 580 g bowl supplies only 3.9 g of protein and 226 mg of sodium. You would run out of appetite long before radishes made a dent in your budget.
So portion size is not the problem with plain radishes. The total moves when they ride along with butter, creamy dips, oily dressing or a sweet pickling liquid, and those extras can easily outweigh the radish itself. Log the additions carefully and treat the slices as close to free.
Carbs supply 79% of the calories, and much of that is fiber
Per 100 g, raw radish holds 3.4 g of carbs, 0.7 g of protein and 0.1 g of fat. By calories, that splits into 79% carbs, 16% protein and 5% fat. Fat is a rounding error here, and saturated fat and cholesterol both sit at 0.
The carbs are not mostly sugar. Of the 3.4 g, 1.9 g are sugars and 1.6 g are fiber, so nearly half of the carbohydrate is fiber. A cup sliced gives 1.9 g of fiber and 2.2 g of sugars for 19 calories, which is a lot of chewing for very little energy.
Protein looks respectable at 16% of the energy, but the grams are tiny: 0.8 g per cup, or 2% of the daily value. Radishes add crunch, color and volume, not protein. If a meal needs to keep you full for hours, the protein has to come from something else on the plate.
Fresh radish is low in sodium, pickled radish is a different food
Raw red radish carries 39 mg of sodium per 100 g and 45 mg per cup sliced, which is 2% of the daily value. Half a cup adds 23 mg. Even five cups stay at 226 mg. If you watch sodium, fresh radishes are an easy yes.
Potassium is the bigger mineral number at 233 mg per 100 g, set against a 4700 mg daily value. Fiber is the other row worth reading: 1.6 g per 100 g counts toward a 28 g daily target while adding almost no calories.
None of this carries over automatically to jarred products. Brands such as Hilo Co-Co Sanbai Zuke Pickled Radish in Soy Sauce or Eden Daikon Radish Pickled With Rice Bran are made with soy sauce, brine or rice bran, so their sodium and sugar can look nothing like the raw row above. Read the label on any pickled or seasoned radish instead of borrowing these numbers.
Use radishes for crunch and pair them with protein
Because a cup costs 19 calories, radishes work best as a volume booster. Slice them into salads, grain bowls and tacos, or set a pile next to sandwiches instead of chips. They bring a peppery bite that makes a plate feel bigger without moving the total much.
Their weak spot is protein, at 0.7 g per 100 g. Pair them with eggs, cottage cheese, tuna, chicken or beans so the meal actually holds you. A small amount of olive oil or a yogurt dip is fine, but measure it, since the dip will carry most of the calories on that plate.
Sliced options like Caldwell Fresh Foods Sliced Red Radish or The Pick Daikon Radish Noodles make radishes easier to use on busy days. If you want to skip the measuring, BodyPal can log radishes from a photo of your plate.
How does radish compare?
Here is how raw radish stacks up against asparagus, brussels sprouts and cooked carrots, per 100 g and per usual serving.
Verdict: For the fewest calories, radish wins at 16 per 100 g, while brussels sprouts run 2.3 times higher at 36 and cooked carrots 2.2 times higher at 35. If you want more protein from your vegetables, pick brussels sprouts at 2.6 g or asparagus at 2.4 g per 100 g over radish at 0.7 g.

Most labeled products here are pickled or sprouted rather than fresh, so their numbers read higher than plain raw radish. Source: manufacturer labels / USDA FoodData Central.
