Are Penne Acidic or Alkaline?
Penne (raw) are acid-forming: Positive PRAL: acid-forming after digestion.
Classification
Dry penne is acid-forming at +10.9 because the dry product contains concentrated protein and phosphorus with no water to dilute it. Cooked, it drops to just +5.8 per 100 g. For your balance, the cooked weight is what counts: an 80 g serving from the package makes just under 200 g on your plate.
In the Grains, Bread & Pasta category, penne (raw) rank #117 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.

Frequently Asked Questions
Are penne 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: Penne (raw) have a PRAL of +10.9 per 100 g, so they count as acid-forming in your daily acid-base balance.
How much spinach offsets a dry serving (50 g) of penne?
A dry serving (50 g) of penne adds +5.5 to your daily balance. Spinach (fresh) has −12.2 per 100 g, so about 50 g of spinach offset this serving.
Do I have to avoid penne on an alkaline diet?
No. What counts is the balance of the whole day, not a single food. Penne are acid-forming; with enough vegetables, potatoes and fruit on the same plate, the meal stays balanced.
Penne, raw or cooked: which is more alkaline?
Penne (raw) is at +10.9, Penne (cooked) at +5.8. So the "cooked" version is more alkaline. Differences come from water content, cooking water or concentration during drying.
