Energy comes from USDA nutrient 1008. Salt is calculated as sodium × 2.5, with unit conversion to grams. It is not a separately measured salt value.
Preparation
An orange is 47 kcal per 100 g and about 87% water; it is eaten raw and the number does not change in a fruit salad. Juicing is the transformation that matters: a glass of orange juice takes the sugar of two or three oranges and leaves the fibre behind — about 110 kcal per 250 ml, drunk in a minute.
Logging this food
USDA's large orange is 184 g and 86 kcal; a typical supermarket orange (about 131 g) is 62; a cup of sections 180 g, 85. Peel is about 25% of the whole weight, so a 200 g orange from the bowl is roughly 150 g of fruit, 70 kcal. Log by count; precision here is not worth a scale.
Swaps and alternatives
Among fruit, orange sits low: strawberries 32 kcal per 100 g, raspberries 52, banana about 89, grapes and cherries 60–70. Mandarins and clementines are close to orange per gram and smaller per piece. Dried fruit (dates 277) and juice are the swaps to avoid if calories are the point.
