PRAL Nutrients are those substances in food and drink that are used in the Potential Renal Acid Load (PRAL) calculation.
The PRAL score is the best indicator of how we can improve an alkaline diet. Though PRAL scores are calculated as absolute numbers, in practice, they should only be used as a general guide. Seasonal variations, different varieties, and cooking methods will all affect the PRAL score. Despite this variation, the numbers are useful in making better food choices. Ultimately, the proof of your alkaline diet comes when you test the pH of urine. The alkaline food lists will help point you in the direction of foods with lower PRAL scores if you need to raise the pH of your urine. There is more information on PRAL pH Balance Calculation.
The key to alkaline diets is that 20-30% of foods should be acidic, with the rest being alkaline or neutral. Overall, your total pH balance diet score should be alkaline. There is no target for PRAL. The target pH of urine in healthy individuals is 6.5 to 7 in the morning, rising to 7.5 through the day. The target should be higher if you are fighting ill health, though there are complications to this that I will consider when I explain various diseases in future articles.
