Orange Juice is 30g of sugar, wrapped in 1g of fiber per 100g. That's what makes it not soda.

The fiber slows absorption; the sugar is not "free sugar" the way added sugar is. Whole fruit and juice are different foods nutritionally, even at the same sugar number.

The chef's caveat

Ripeness matters

A greener orange juice has more starch and less sugar; a spotty one is the reverse. Total calories barely move, but if you are tracking blood sugar or fiber-vs-sugar ratio, ripeness is a real variable — not a rounding error.

Common questions

The stuff people actually ask.

How many calories in fl oz of orange juice?

About 49 calories, with roughly 0.8g of protein. fl oz weighs about 33g. Use the slider above for any other portion.

Does a ripe orange juice have more calories?

Barely. As fruit ripens, starch converts to sugar — same calories, different molecule. What changes: sweeter taste, faster blood-sugar rise, softer texture. Total calories move maybe 3–5%.

Is orange juice actually healthy, or is that marketing?

By the numbers on this page: fiber, vitamin C, potassium; sugar comes with its brake pedal (fiber).
