Are Spaghetti Acidic or Alkaline?
Spaghetti (raw) are acid-forming: Positive PRAL: acid-forming after digestion.
Classification
Uncooked, spaghetti reaches +10.9, because durum wheat semolina contains a lot of protein and phosphorus per 100 g of dry weight. After cooking, the value drops to +5.8, since the pasta soaks up water. So for your plate, use the cooked value: 100 g of dry pasta makes about 240 g cooked.
In the Grains, Bread & Pasta category, spaghetti (raw) rank #118 of 121, sorted from alkaline to acid-forming. More alkaline options include Whole spelt flour (+10.5), Wheat tortilla (wrap) (+10.0), Corn flour (+9.7). More acid-forming are Oat flour (+12.2), Oat bran (+17.1), Wheat germ (+20.1).
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 spaghetti
A dry serving (50 g) of spaghetti adds +5.5 to your daily balance. These three bring it back; the grams shown offset exactly this serving.
Frequently Asked Questions
Are spaghetti 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: Spaghetti (raw) have a PRAL of +10.9 per 100 g, so they count as acid-forming in your daily acid-base balance.
How much lamb's lettuce offsets a dry serving (50 g) of spaghetti?
A dry serving (50 g) of spaghetti adds +5.5 to your daily balance. Lamb's lettuce (fresh) has −8.3 per 100 g, so about 70 g of lamb's lettuce offset this serving.
Do I have to avoid spaghetti on an alkaline diet?
No. What counts is the balance of the whole day, not a single food. Spaghetti are acid-forming; with enough vegetables, potatoes and fruit on the same plate, the meal stays balanced.
Spaghetti, raw or cooked: which is more alkaline?
Spaghetti (raw) is at +10.9, Spaghetti (cooked) at +5.8. So the "cooked" version is more alkaline. Differences come from water content, cooking water or concentration during drying.
