Potential Renal Acid Load

PRAL Calculator

Calculates a customized per meal (actual serving) PRAL for a given food.

This calculator will help you more accurately estimate the potential renal acid load (PRAL) of a real life serving (or multiple servings) of a given food. A "real life" serving is not necessarily the same as the "Servings Size" specified on food Nutrition Facts labels. Neither is it always 100 grams, the serving size on which PRAL charts are based. The calculator allows you to balance, say, a pound of ground beef with a 29 oz can of tomatoes in a chili recipe.

This is not a lookup app. The calculator derives PRAL from user-supplied data. The accuracy of the calculation depends on the accuracy of your inputs. Enter real numbers to get real results.

The manual entry process has 3 steps:

  1. Food name (for reference)
  2. Data (derived from Nutrition Facts label or other source)
  3. My serving
When entries are complete, click CALCULATE.    

1. Food Name/Description

Food name:

2. Data (derived from Nutrition Facts label or other source):

Carefully enter (or copy/paste) the requested information for the specified Serving Size from the Nutrition Facts panel on food packaging or other source (see box).

"Nutrition Facts" vs Data Sources on the WebThe 'Nutrition Facts' panels on food packages rarely show complete nutritional information. Also, food manufacturers are allowed (by the FDA) to round the figures; they often round to zero. There are several sources on the Web that are better. Start with the USDA National Nutrient Database. If you don't mind seeing ads, you might find SELFNutritionData slightly easier to use.

Select g/mg, ounces or %DV from drop-down menus.

Reference Serving*:
  
Protein:
Calcium:
Magnesium:
Phosphorus:
Potassium:

*Be sure to enter the serving size stated in the data source. This is a reference serving. Your actual serving size, which may be higher or lower, will be entered below.

3. My Serving:

The actual quantity as part of a meal, daily total or recipe.

Enter:

  • a multiple of the "Reference Serving" entry above, for example 1.5
    OR..
  • the serving's weight (ounces or grams).

Select servings (xRef), ounces or grams (mL) from the drop-down menu.
