Is Salmon Acidic or Alkaline?

Salmon: Is Salmon Acidic or Alkaline?
Quick answer
Acidic
PRAL per 100 g
+11.5
Salmon (prepared)

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.

Why salmon is acid-forming

In the acid-base balance, fish comes close to meat: salmon +11.5, trout +10.1, cod +8.7, canned tuna +12.0 and fried tuna +13.1 per 100 g. A 150 g salmon fillet adds +17.3 to your balance.

That's no reason to skip fish. Omega-3 fatty acids, iodine and vitamin D are hard to get from other foods. The answer is what else goes on your plate: salmon with 200 g of potatoes (−13.1) and 150 g of spinach (−19.4) makes an alkaline meal overall. Salmon with rice and cream sauce does not.

Acidic or alkaline: PRAL, not pH

The PRAL (potential renal acid load) estimates what a food leaves behind after digestion. It is not the pH of the food itself: a lemon tastes sour, yet its PRAL is −4.0. If you are asking whether salmon is acidic because of heartburn or reflux, that is a question of pH and your stomach, which the PRAL does not measure; talk to your doctor about it.

Everyday tip: Always pair fish with two alkaline sides: potatoes or sweet potato plus a green vegetable. That way the meal as a whole stays in the negative, even with the fish.
