Is Potato Bread Acidic or Alkaline?
Potato bread (baked) is slightly acid-forming: Positive PRAL: acid-forming after digestion.
Classification
Potato bread is acid-forming at +4.7 because the wheat in the dough, with its protein and phosphorus, drives the calculation. The potato share is too small to offset it. The potato makes the bread moister but changes little in the balance. A 50 g slice adds about +2. Cucumber and radish as toppings pull it back toward zero.
In the Grains, Bread & Pasta category, potato bread (baked) ranks #60 of 121, sorted from alkaline to acid-forming. More alkaline options include Rye, whole kernel (+4.4), Wholemeal roll (+4.3), Wholemeal toast bread (+4.3). More acid-forming are White rice (+4.7), Wholemeal wheat bread (+4.9), Breadcrumbs (+5.0).
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 potato bread
Two slices (100 g) of potato bread adds +4.7 to your daily balance. These three bring it back; the grams shown offset exactly this serving.
Frequently Asked Questions
Is potato bread 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: Potato bread (baked) has a PRAL of +4.7 per 100 g, so it counts as slightly acid-forming in your daily acid-base balance.
How much kale offsets two slices (100 g) of potato bread?
Two slices (100 g) of potato bread adds +4.7 to your daily balance. Kale (fresh) has −11.7 per 100 g, so about 40 g of kale offset this serving.
Do I have to avoid potato bread on an alkaline diet?
No. What counts is the balance of the whole day, not a single food. Potato bread is slightly acid-forming; with enough vegetables, potatoes and fruit on the same plate, the meal stays balanced.
