Is Pizza Tuna Acidic or Alkaline?
Pizza tuna (prepared) is acid-forming: Positive PRAL: acid-forming after digestion.
Classification
Tuna pizza is acid-forming at +5.4 because tuna, being fish, brings a lot of protein and phosphorus and raises the balance well above the margherita. The red onions on top bring back a little potassium. At 228 kcal per 100 g, it sits in the middle of the pizza range, and a tomato salad on the side offsets part of the acid load.
In the Meals & Fast Food category, pizza tuna (prepared) ranks #95 of 118, sorted from alkaline to acid-forming. More alkaline options include Pizza Prosciutto e Funghi (+5.3), Pizza Prosciutto (+5.3), Meat salad (with mayonnaise) (+5.3). More acid-forming are Pizza calzone (+5.4), Big Mac (McDonald´s) (+5.6), Fish sticks (frozen) (+5.8).
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 pizza tuna
A meal (300 g) of pizza tuna adds +16.3 to your daily balance. These three bring it back; the grams shown offset exactly this serving.
Frequently Asked Questions
Is pizza tuna 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: Pizza tuna (prepared) has a PRAL of +5.4 per 100 g, so it counts as acid-forming in your daily acid-base balance.
How much kale offsets a meal (300 g) of pizza tuna?
A meal (300 g) of pizza tuna adds +16.3 to your daily balance. Kale (fresh) has −11.7 per 100 g, so about 140 g of kale offset this serving.
Do I have to avoid pizza tuna on an alkaline diet?
No. What counts is the balance of the whole day, not a single food. Pizza tuna is acid-forming; with enough vegetables, potatoes and fruit on the same plate, the meal stays balanced.
