What is the Potential Renal Acid Load (PRAL) index?
The Potential Renal Acid Load (PRAL) index, developed by Remer & Manz in 1995, categorizes foods based on their metabolic acid or base load after digestion. It shows that meat, fish, eggs, and grains produce a net acid load, while fruits and vegetables yield a net base load. However, this does not imply that dietary changes will affect blood pH significantly in healthy individuals.
