Is Peach Acidic or Alkaline?
Peach (fresh) is alkaline: Negative PRAL: alkalizing after digestion.
Classification
Peaches are alkaline at −3.4 because the juicy flesh brings potassium and contains hardly any protein. At 39 kcal per 100 g, they make a light summer snack, and one 150 g fruit adds about −5. Much less is left in nectar, because water and sugar stretch the fruit content.
In the Fruit category, peach (fresh) ranks #45 of 80, sorted from alkaline to acid-forming. More alkaline options include Mulberry (−3.4), Red grapes (−3.5), Quince (−3.6). More acid-forming are Pomelo (−3.4), Gooseberry (−3.3), Mango (−3.3).
Acidic or alkaline: PRAL, not pH
On this site, acidic and alkaline refer to the PRAL (potential renal acid load). It estimates what a food leaves behind once it has been digested: a positive value is acid-forming, a negative value is alkalizing. That is different from the pH of the food itself: a lemon tastes sour, yet its PRAL is −4.0, so it is alkalizing. Your diet does not change your blood pH. It does change how much acid your kidneys have to deal with.

Frequently Asked Questions
Is peach acidic?
It depends on what you mean by acidic. The pH describes the food itself, for example how sour it tastes. The PRAL describes what it leaves behind after digestion: Peach (fresh) has a PRAL of −3.4 per 100 g, so it counts as alkaline in your daily acid-base balance.
How much peach do I need for a noticeable effect?
One piece or a handful (120 g) of peach adds −4.1 to your daily balance. For comparison: an egg is around +5.4, a slice of cheese around +6. So one serving of peach roughly offsets one of them.
Why is peach alkaline even though it tastes sour?
The PRAL depends on the minerals left over after digestion, not on taste or pH. Peach provides more potassium, magnesium and calcium than phosphorus and protein, so the balance is negative (−3.4).
