Calories in radish, serving by serving

1 cup of radish slices supplies 19 calories, which scales to 16 per 100 g. Each serving listed underneath was weighed by USDA rather than estimated.

Radish and its protein content

There are 0.8 g of protein in 1 cup of radish slices, or 2 percent of the 50 g the FDA uses as a daily reference. Protein is close to absent in radish. Its calories come from carbohydrate instead.

By calories rather than by weight the split is 16 percent protein, 5 percent fat and 79 percent carbohydrate, so in practice it is mostly a carbohydrate rather than anything else.

What to know before you cook radish

This root crop arrives in shops as round red globes, long white mooli, or dark winter varieties. Look for firm, heavy roots with crisp skins. Avoid any with soft spots or dull, wrinkled coats. If the green tops are attached, they must look bright and fresh, not yellowed or wet with decay.

Applying heat tempers the sharp mustard heat of raw radish, turning the flesh mild and sweet. Roasting or braising softens the crisp texture to something resembling turnips. The common mistake is overcooking them until they turn watery and lose all their peppery character, or discarding the edible, prickly green tops.

Raw slices add crunch to British salads and open sandwiches with salted butter. In Mexican kitchens, they garnish rich stews like pozole to cut through the fat. Asian cuisines pickle them in vinegar or salt to serve alongside fried foods. The peppery flavour pairs well with soft cheeses and fresh herbs.

Micronutrients in radish

The figures worth noticing in 1 cup of radish slices are 19 percent of a day’s vitamin C. The full list follows and tracks your selected portion.

How far radish goes in a day

If you eat 2,000 calories a day, 1 cup of radish slices accounts for 1 percent of them, and for 2 percent of the 50 g protein benchmark. To replace 2,000 with your real number, use the TDEE calculator; to turn that into targets, the macro calculator.

Common questions on radish

How many calories does 1 cup of radish slices have?

1 cup of radish slices is 19 calories. That comes from the USDA record “Radishes, raw” (FDC 169276), which is 16 calories per 100 g.

How much protein does radish have?

0.7 g per 100 g, so 1 cup of radish slices supplies 0.8 g. Against the Daily Value that is 2 percent.

Can you eat radish when trying to lose weight?

That depends on the rest of the day, not on radish. For planning: 1 cup of radish slices is 19 calories and 0.8 g of protein, 17 percent protein by energy, which means it needs a protein-rich partner on the plate.

How much carbohydrate does radish contain?

Carbohydrate comes to 3.9 g per serving of 1 cup of radish slices: 2.2 g as sugar and 1.9 g as fibre.

How do you store radishes to keep them crisp?

Cut off the green tops immediately, as they draw moisture from the root. Keep the unwashed roots in a sealed bag in the fridge drawer. If they soften, submerge them in iced water to restore their crunch.

Why are some radishes too spicy to eat?

Heat and dry soil during growth increase the mustard oils in the root, making them very hot. You can reduce this sharp bite by peeling the skin, soaking slices in cold water, or cooking them.
