Is Couscous (Durum) Acidic or Alkaline?
Couscous (durum) (cooked) is slightly acid-forming: Positive PRAL: acid-forming after digestion.
Classification
Cooked couscous comes in at +2.5, raw couscous at +5.9. The durum wheat semolina brings protein and phosphorus, but it absorbs a lot of water as it swells, which dilutes the acid load per 100 g. That makes it slightly milder than cooked bulgur. With roasted vegetables and herbs, the bowl is balanced overall. With lamb, it shifts toward acid-forming.
In the Grains, Bread & Pasta category, couscous (durum) (cooked) ranks #26 of 121, sorted from alkaline to acid-forming. More alkaline options include Pearled barley (+2.3), Pumpernickel (+2.3), Rice noodles (+2.1). More acid-forming are Wholemeal bread (+2.6), Multigrain bread (+2.6), Wild rice (+2.6).
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 couscous (durum) 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: Couscous (durum) (cooked) has a PRAL of +2.5 per 100 g, so it counts as slightly acid-forming in your daily acid-base balance.
How much avocado offsets a small side (100 g) of couscous (durum)?
A small side (100 g) of couscous (durum) adds +2.5 to your daily balance. Avocado (ripe) has −9.9 per 100 g, so about 20 g of avocado offset this serving.
Do I have to avoid couscous (durum) on an alkaline diet?
No. What counts is the balance of the whole day, not a single food. Couscous (durum) is slightly acid-forming; with enough vegetables, potatoes and fruit on the same plate, the meal stays balanced.
Couscous (durum), cooked or raw: which is more alkaline?
