With 9.6g sugar per 100g and a low glycemic load of 5, a typical 250ml glass (about 24g sugar) raises blood glucose moderately but rapidly because there's no fiber to slow absorption. The 0.2g fiber per 100g is negligible, so glucose enters your bloodstream quickly, prompting an insulin surge that can lead to an energy crash within 1–2 hours.
Each 100g provides 101mg potassium (2% DV), which helps counter sodium's effects on blood pressure and supports muscle contractions. The 88.24g water per 100g contributes to daily fluid needs, but the high sugar content makes it less hydrating than plain water.
At 0.1g protein and 0.2g fiber per 100g, apple juice has almost no protein or fiber, so it won't keep you full. Replacing whole apples with juice means you miss out on the fruit's fiber (a whole apple has ~2.4g fiber per 100g) and the chewing effect that triggers fullness hormones.
A 250ml glass (about 250g) delivers ~478 calories (191 kcal per 100g). Because it's liquid, your brain doesn't register those calories as solid food, so you may not reduce other food intake, leading to weight gain over weeks.
Verdict
Drinking apple juice daily is fine in small amounts (≤150ml) but not as a hydration staple. For steady energy and satiety, eat whole apples instead—you'll get fiber and fewer calories per volume.
