Is Salmon Acidic or Alkaline?
Salmon (prepared) is acid-forming: Positive PRAL: acid-forming after digestion. Acid-forming, not alkaline: prepared salmon has a PRAL of +11.5 per 100 g. The same goes for every fish, because fish is concentrated protein with plenty of phosphorus.
Classification
Cooked salmon, at +11.5, is a bit above raw salmon at +9.3. Pan-frying or steaming releases water, so protein and phosphorus per 100 g go up. A 150 g fillet therefore comes to about +17. Boiled potatoes in their skins and a large serving of broccoli or spinach on the side take back a good part of that.
In the Fish & Seafood category, salmon (prepared) ranks #50 of 56, sorted from alkaline to acid-forming. More alkaline options include Tuna (+11.4), Buckling (smoked herring) (+11.3), Shrimps (+11.1). More acid-forming are Tuna (+12.0), Eel (+13.0), Tuna (+13.1).
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 salmon
One salmon fillet (150 g) of salmon adds +17.3 to your daily balance. These three bring it back; the grams shown offset exactly this serving.
Frequently Asked Questions
Is salmon 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: Salmon (prepared) has a PRAL of +11.5 per 100 g, so it counts as acid-forming in your daily acid-base balance.
How much lamb's lettuce offsets one salmon fillet (150 g) of salmon?
One salmon fillet (150 g) of salmon adds +17.3 to your daily balance. Lamb's lettuce (fresh) has −8.3 per 100 g, so about 210 g of lamb's lettuce offset this serving.
Do I have to avoid salmon on an alkaline diet?
No. What counts is the balance of the whole day, not a single food. Salmon is acid-forming; with enough vegetables, potatoes and fruit on the same plate, the meal stays balanced.
Salmon, prepared or smoked: which is more alkaline?
Salmon (prepared) is at +11.5, Salmon (smoked) at +11.2. So the "smoked" version is more alkaline. Differences come from water content, cooking water or concentration during drying.
