How to read the list
The PRAL (potential renal acid load) shows how much acid or base 100 g of a food leave behind after digestion, calculated from protein, phosphorus, potassium, magnesium and calcium. Values below −0.5 count as alkaline here, above +0.5 as acid-forming, in between as neutral. For your daily balance, the sum of all servings counts, not a single food. Drinks are listed per 100 ml.
The PRAL is not the pH of a food. Lemons, tomatoes and coffee have an acidic pH, yet all three have a negative PRAL: after digestion, they are alkalizing. That is why this list sometimes disagrees with charts that sort foods by taste or pH.
The most common questions ("Is coffee acidic?", "Are oats acidic?") are answered in detail in Acidic or Alkaline?. You can add up a whole meal in the PRAL calculator. How the value is calculated and where its limits lie is explained in What Is PRAL? Formula and Calculation.
The list in your pocket, with a daily balance.
