Is Marzipan Acidic or Alkaline?
Marzipan (prepared) is slightly acid-forming: Positive PRAL: acid-forming after digestion.
Classification
Marzipan is slightly acid-forming at +2.0 because the ground almonds bring protein and phosphorus, but the high sugar content dilutes them heavily. Plain almonds are many times higher per 100 g. A 10 g marzipan potato adds about +0.2. The value says nothing about sugar or the 407 kcal per 100 g.
In the Sweets & Snacks category, marzipan (prepared) ranks #52 of 91, sorted from alkaline to acid-forming. More alkaline options include Snickers (+1.3), Donut (+1.2), Marshmallows (+0.9). More acid-forming are Danube wave cake (+2.0), Bee sting cake (+2.1), Tortilla chips (+2.2).
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.
What balances marzipan
A small serving (40 g) of marzipan adds +0.8 to your daily balance. These three bring it back; the grams shown offset exactly this serving.
Frequently Asked Questions
Is marzipan 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: Marzipan (prepared) has a PRAL of +2.0 per 100 g, so it counts as slightly acid-forming in your daily acid-base balance.
How much avocado offsets a small serving (40 g) of marzipan?
A small serving (40 g) of marzipan adds +0.8 to your daily balance. Avocado (ripe) has −9.9 per 100 g, so about 10 g of avocado offset this serving.
Do I have to avoid marzipan on an alkaline diet?
No. What counts is the balance of the whole day, not a single food. Marzipan is slightly acid-forming; with enough vegetables, potatoes and fruit on the same plate, the meal stays balanced.
