Is Sushi with Tuna Acidic or Alkaline?
Sushi with tuna (prepared) is slightly acid-forming: Positive PRAL: acid-forming after digestion.
Classification
Tuna sushi comes in at +4.0, slightly above the salmon version (+3.2), even though raw tuna on its own sits at +11.4. The rice makes the difference: it dilutes the fish's protein to a fraction per 100 g. A whole 300 g platter adds up to about +12, and a cucumber salad on the side offsets some of it.

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 sushi with 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: Sushi with tuna (prepared) has a PRAL of +4.0 per 100 g, so it counts as slightly acid-forming in your daily acid-base balance.
How much spinach offsets a meal (300 g) of sushi with tuna?

No. What counts is the balance of the whole day, not a single food. Sushi with tuna is slightly acid-forming; with enough vegetables, potatoes and fruit on the same plate, the meal stays balanced.
