Orange Calories & Nutrition Calculator

Orange contains 53.2mg vitamin C per 100g — 59% of the daily value. This is the fruit the world uses as the vitamin C reference point. When we say guava has '4x more vitamin C than orange,' or that lemon has '1x orange's vitamin C,' orange is the baseline. A medium orange (131g) delivers 69.7mg vitamin C — 77% DV from a single fruit ^[1].

Navel oranges have slightly more: 59.1mg vitamin C per 100g (66% DV). Valencia oranges are similar at ~49mg. The variety matters, but all oranges deliver substantial vitamin C. Fresh orange juice retains most of it: 50mg per 100ml — though commercial pasteurized juice can lose 10-30% during processing.

For food journaling, one medium orange provides the majority of daily vitamin C needs at just 62 kcal. Two oranges cover 154% DV. The vitamin C is accompanied by hesperidin and other flavanones that are unique to citrus and not reflected in standard nutrient panels.

Whole orange has 2.4g fiber per 100g (9% DV). Orange juice has 0.2g per 100g — a 12x reduction. This is the single largest nutritional difference between the whole fruit and its juice. A medium orange (131g) provides 3.1g fiber (11% DV). A cup of orange juice (248g) provides 0.5g fiber (2% DV) ^[1].

The fiber is concentrated in the white pith (albedo) and cell membranes that are removed during juicing. The pith alone contains about 10g fiber per 100g — more than most high-fiber fruits. For food journaling purposes, eating orange segments with some pith intact maximizes fiber intake versus carefully removing all pith.

The sugar content is similar: whole orange has 9.35g sugar per 100g, and juice has 8.4g. However, the whole fruit includes 2.4g of fiber alongside those sugars while juice has nearly none. This structural difference is why whole orange and orange juice, despite similar sugar and vitamin C content, are nutritionally distinct foods for journaling.

Beyond vitamin C, orange has a broader nutrient profile than most fruits. 40mg calcium per 100g is notable — most fruits have 5-15mg. A cup of orange sections (180g) provides 72mg calcium (6% DV). This is modest compared to dairy but unusually high for fruit ^[1].

Orange also delivers 30mcg folate per 100g (8% DV). A medium orange provides 39mcg. Navel oranges have more: 34mcg per 100g. Folate is often under-tracked in food journals. One medium orange contributes 39mcg folate (10% DV), making it a meaningful contributor when combined with other folate-rich foods like leafy greens and legumes.

Potassium is 181mg per 100g — moderate but consistent. A cup of juice actually has more potassium per serving (496mg from 248g) than a whole fruit (237mg from 131g), because juice is consumed in larger volumes. For potassium tracking specifically, juice is the more concentrated source.

Navel orange: 49 kcal, 12.54g carbs, 59.1mg vitamin C, 166mg potassium, 34mcg folate. All commercial varieties (average): 47 kcal, 11.75g carbs, 53.2mg vitamin C, 181mg potassium, 30mcg folate. The calorie difference between any orange variety is less than 5% ^[1].

Where they differ more: navel oranges have 11% more vitamin C (59.1 vs 53.2mg) and 13% more folate (34 vs 30mcg). The all-varieties average has 9% more potassium (181 vs 166mg). These differences are real but small enough that for most food journaling, any orange variety can be logged interchangeably.

The bigger distinction is orange type vs preparation: whole fruit vs juice vs sections vs with peel. These differences (especially the 12x fiber gap) are far more impactful than variety differences. The calculator lets you select the specific variant that matches your intake.

A small orange (96g) has 45 kcal. Medium (131g) = 62 kcal. Large (184g) = 86 kcal. One cup orange sections (180g) = 85 kcal. Oranges vary in size by nearly 2x (96g to 184g), so portion accuracy matters for tight calorie tracking ^[1].

Orange juice is where calories accumulate: one cup fresh-squeezed (248g) has 112 kcal — equivalent to about 1.8 whole medium oranges. Two cups of juice (a common serving at breakfast) = 224 kcal, equivalent to 3.6 medium oranges. Most people would never eat 4 oranges at once but easily drink that amount as juice.

For food journaling, track whole oranges by size (small/medium/large) and juice by measured volume. A glass of juice that looks like 'one cup' is often 350-400ml, which would be 158-180 kcal rather than the expected 112. Measuring juice portions is one of the most impactful logging accuracy improvements.
