Is Roast Beef Acidic or Alkaline?
Roast beef (prepared) is strongly acid-forming: Positive PRAL: acid-forming after digestion. Acid-forming. Every type of meat is acid-forming: roast beef +12.9, beef mince +12.1, pork chop +13.7 and chicken breast +13.2 per 100 g prepared, while sausage usually falls between +5 and +15.
Classification
Braised roast beef comes in at +12.9, higher than raw (+9.2), because water escapes during cooking and leaves protein and phosphorus more concentrated per 100 g. Two slices weighing 150 g together come to about +19. Plenty of red cabbage, potatoes and a gravy with root vegetables offset part of that. The meat carries the rest on its own.
In the Meat & Sausages category, roast beef (prepared) ranks #55 of 67, sorted from alkaline to acid-forming. More alkaline options include Rabbit meat (+12.8), Roast chicken (with skin) (+12.5), Chicken liver (+12.3). More acid-forming are Turkey breast (+13.0), Chicken breast (+13.2), Pork roast (+13.3).
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 roast beef 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: Roast beef (prepared) has a PRAL of +12.9 per 100 g, so it counts as strongly acid-forming in your daily acid-base balance.
How much avocado offsets one steak (150 g) of roast beef?
One steak (150 g) of roast beef adds +19.3 to your daily balance. Avocado (ripe) has −9.9 per 100 g, so about 200 g of avocado offset this serving.
Do I have to avoid roast beef on an alkaline diet?
No. What counts is the balance of the whole day, not a single food. Roast beef is strongly acid-forming; with enough vegetables, potatoes and fruit on the same plate, the meal stays balanced.
Roast beef, prepared or raw: which is more alkaline?
Roast beef (prepared) is at +12.9, Roast beef (raw) at +9.2. So the "raw" version is more alkaline. Differences come from water content, cooking water or concentration during drying.
