Apples: Are Apples Acidic or Alkaline?
Quick answer
Alkaline

Apple (fresh)

Mildly alkaline. An apple has a PRAL of −1.9 per 100 g, which puts it at the lower end among fruits, but it is still clearly alkaline.

Why apples are alkaline

Apples are 85% water, so their mineral density is lower than that of bananas (−6.4) or dates (−7.8). A 150 g apple adds −2.9 to your daily balance. Dried apple rings concentrate the potassium and reach −10.2 per 100 g.

The apple's strength is not its value but the habit. It is the most eaten fruit in Germany, always available and an easy snack. Two apples a day add up to −5.8, plus fiber and polyphenols from the skin. Pear, at −2.3, is about the same.

Acidic or alkaline: PRAL, not pH

The PRAL (potential renal acid load) estimates what a food leaves behind after digestion. It is not the pH of the food itself: a lemon tastes sour, yet its PRAL is −4.0. If you are asking whether apples are acidic because of heartburn or reflux, that is a question of pH and your stomach, which the PRAL does not measure; talk to your doctor about it.

Everyday tip: Make an apple your default snack instead of a cereal bar (+3.0) or cheese cubes (+5.3 per 30 g). Each swap gains you three to eight points.

Apples in different forms: raw, cooked, processed

Frequently Asked Questions

Is apple juice acidic?

No, it is alkaline: −1.8 per 100 ml, similar to the fruit. But a glass has no fiber and the sugar of three apples, so the whole fruit is the better choice.

What fruits are more alkaline than apples?

Almost all of them: banana (−6.4), kiwifruit (−4.9), orange (−2.8), apricot (−7.2). Apples are alkaline, but they are not a top performer.
