Acidic Alkaline Food Balancing and PRAL value of Food

Acidic Alkaline Food Balancing and PRAL value of Food

In the acidic/alkaline food chart, you will notice few alkaline foods in comparison to that of acidic food which is extremely large in number. Unfortunately most of the acidic food listed above may be your favorite ones you crave on. It is somewhat alright if you consume slightly acidic food since there is a minimal difference and you can easily balance it by consuming minimal alkaline stuff, however acidic food stuffs should be avoided as much as possible since you will need to consume more of alkaline stuff to balance it otherwise several health complications may arise. Very acidic food stuff should be completely avoided since it would require too much of alkaline food stuff in order to balance it otherwise critical health problems may arise.

For understanding the above scenario it is important to know about the nutritional value of food/dish and the pH value of the nutrients. Based on this we can determine the nature of the food/dish whether it is alkaline or acidic. The oldest and a simple method to know the nature of food is by using PRAL (Potential Renal Acid Load) formula. The formula for knowing the PRAL value is PRAL = 0.49 x Grams of Protein + 0.037 x Milligrams of Phosphorus – 0.021 x Milligrams of Potassium – 0.026 x Milligrams of Magnesium – 0.013 x Milligrams of Calcium. If the result of PRAL value is positive it means the particular diet is acidic and on the other hand the particular diet is alkaline if the said value if negative. For instance:- If a particular dish contains 25gms of protein, 400mg of phosphorus, 600mg of potassium, 400mg of magnesium and 500mg of calcium then based on the PRAL formula the value results into negative variable i.e -2.45 which is said to be alkaline. Similarly, if a particular dish contains 30gms of protein, 600mg of phosphorus, 600mg of potassium, 400mg of magnesium and 500mg of calcium then the end result would be acidic since the variable falls into positive value i.e 7.3.

In order to calculate PRAL, it is important to know about the nutritional value of the ingredients which are used in food. For example:- if you use 100gm of onions, 80gms of tomato, 2tbsp of ginger & garlic paste etc in the food, you will need to know the value of nutrition required for calculating PRAL. This is simple method of recognizing the nature of food which in turn will help you to balance the acidity and alkalinity in food.
