Is Mirabelle Plum Acidic or Alkaline?
Mirabelle plum (fresh) is alkaline: Negative PRAL: alkalizing after digestion.
Classification
Mirabelle plums come in at −3.8, in the alkaline range, because the flesh contains potassium and hardly any protein. That makes them a little more alkaline than regular plums. A 150 g bowl fresh from the tree adds about −6. As a cake topping, they offset part of the acid-forming dough.
In the Fruit category, mirabelle plum (fresh) ranks #38 of 80, sorted from alkaline to acid-forming. More alkaline options include Pomegranate (−3.8), Lemon (−4.0), Nectarine (−4.0). More acid-forming are White grapes (−3.8), Sweet cherry (−3.7), Mangosteen (−3.6).
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 mirabelle plum 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: Mirabelle plum (fresh) has a PRAL of −3.8 per 100 g, so it counts as alkaline in your daily acid-base balance.
How much mirabelle plum do I need for a noticeable effect?
One piece or a handful (120 g) of mirabelle plum adds −4.6 to your daily balance. For comparison: an egg is around +5.4, a slice of cheese around +6. So one serving of mirabelle plum roughly offsets one of them.
Why is mirabelle plum alkaline even though it tastes sour?
The PRAL depends on the minerals left over after digestion, not on taste or pH. Mirabelle plum provides more potassium, magnesium and calcium than phosphorus and protein, so the balance is negative (−3.8).
