The Radish Fat Per 100g Calculator takes the guesswork out of tracking the fat content of radishes. Radishes are famously low-fat — raw radishes contain just 0.1 g of fat per 100 g — which makes them a smart crunchy snack for low-fat, keto, or calorie-conscious eating plans. This tool converts your chosen portion size (grams, ounces, cups, or individual radishes) into total fat, fat calories, and percent of daily fat value.
Whether you are logging meals in a macros app, building a low-calorie salad, or simply curious about nutrition labels, this calculator gives you quick, practical answers. Choose a radish type, enter your portion, and get a clear breakdown. You can also compare raw radish and daikon, or enter a custom fat value if you are using a specific lab-tested or packaged product.

How to Use the Radish Fat Calculator
Start by selecting the radish type that matches your meal. The calculator uses USDA food-composition values: raw common radishes and daikon radishes both contain 0.1 g of fat per 100 g. If you are tracking a specific packaged or specialty radish product, enter its own fat value in the optional custom-fat field and the calculator will use that number instead.
Next, enter a portion size and choose the matching unit. You can type grams directly, use ounces, use volume in sliced cups, or count individual medium radishes. The calculator automatically converts everything to grams before computing fat. Click Calculate Fat to see your total fat in grams, fat calories, and percent of the daily value.
- Use the preset buttons for common portions: 100 g, 1 oz, 1 cup, or 1 medium radish.
- For recipe calculations, add the fat from multiple ingredients manually or reset and repeat.
- For a low-fat diet, remember that any visible fat on radish dishes usually comes from added oil, butter, or dressing — not the radish itself.
Why Radish Fat Is So Low
Radishes are about 95% water by weight. The remaining dry matter is mostly carbohydrates (including fiber) and a small amount of protein, leaving almost no room for fat. The 0.1 g of fat per 100 g in raw radishes is far below the 5 g per 100 g threshold that food-labeling rules often use to define a low-fat food. A 100 g portion of raw radish also provides roughly 16 calories, 3.4 g of carbohydrates, 0.7 g of protein, and 1.6 g of fiber.
Daikon radish is similar: about 0.1 g fat, 18 calories, 4.1 g carbs, and 0.6 g protein per 100 g. From a fat-tracking perspective, the two are effectively interchangeable. The main difference in a recipe is texture, moisture, and mild flavor, not macronutrients.
Worked Examples
Grams = 150. Total fat = 150 × 0.1 / 100 = 0.150 g. Calories from fat = 0.150 × 9 = 1.35 kcal. Daily value contribution = 0.150 / 78 × 100 ≈ 0.19%.
Total fat = 116 × 0.1 / 100 = 0.116 g. That is roughly 1.04 kcal from fat and about 0.15% of a 78 g daily value.
Total fat = 4.5 × 0.1 / 100 = 0.0045 g. Crunching a single radish adds less than 0.05 kcal from fat, essentially zero for meal logging.
Radish Fat Reference Table
Typical fat values for common raw radish portions, based on 0.1 g fat per 100 g and standard portion weights.
| Portion | Approximate Weight | Fat Content |
|---|---|---|
| 100 g (3.5 oz) | 100 g | 0.100 g |
| 1 cup sliced | 116 g | 0.116 g |
| 1 medium radish | 4.5 g | 0.005 g |
| 1 oz | 28.35 g | 0.028 g |
| 1 cup (daikon, sliced) | 116 g | 0.116 g |
Factors That Affect Accuracy
Standard nutrient databases give average values, not exact lab results for every radish. Actual fat can vary slightly with variety, soil, water content, and growing season, but the differences are tiny. What matters more is preparation: radishes fried, roasted with oil, or served with butter will contain much more fat than raw values on this page. The calculator is designed for raw or cooked radishes without added fat.
Measuring by weight using grams is always more accurate than cups. A cup of sliced radishes can vary by several grams depending on how thick you slice them and how tightly they are packed. If you need precise tracking for a strict diet, weigh the radish on a kitchen scale rather than relying on volume.
Frequently Asked Questions
Is radish fat-free?
Not technically, but it is so low that many labels round it to 0 g. Raw radish has about 0.1 g of fat per 100 g, which is below the FDA's threshold of 0.5 g per serving to be labeled fat-free.
Does daikon have more fat than red radish?
No, both raw daikon and common red radishes provide about 0.1 g of fat per 100 g. The calories and carbohydrate content are slightly different, but fat is essentially the same.
How do I include radishes in a keto or low-fat diet?
Radishes are a good fit for both. A cup of sliced radishes has about 0.12 g fat and roughly 2 g net carbs, making it a crunchy, low-calorie option. If you are watching carbs, you can use the vegetable sugar calculator to compare sugar across other vegetables.
Why do some labels show 0 g fat if the food has fat?
Food labeling rules allow 0 g if a serving contains less than 0.5 g of fat. Since a typical serving of radishes is well below that, labels often round down. The calculator shows the unrounded value for more precise tracking.
For deeper nutrition data, the USDA FoodData Central database is the authoritative source for radish composition values, and the FDA nutrition facts label page explains daily value and rounding rules.
