List of Acid / Alkaline Food

Here is a brief overview of some foods that have been evaluated with the index of P.R.A.L.

What is P.R.A.L. ?

The alkalinizing power of each food is calculated by the index of P.R.A.L. (POTENTIAL RENAL ACID LOAD),

It is the minerals in foods that determine these characteristics: vegetables, for example, combine a good amount of calcium, magnesium, sodium and potassium (basic mineral) to a low chlorine content, sulfur and phosphorus (acid mineral)

Put simply, foods high in protein such as meat and cheese, and cereal products are acidifying. The two food groups that are alkalizing are the fruits and vegetables.

An index greater than zero indicates food that is acid
An index lower than zero indicates food that is basic

*Some sources consider coffee as alkalizing, but even though it contains some minerals and contains no protein, it is acidifying. This is a “thief of calcium” and therefore a risk factor for osteoporosis

Note that a food’s acid or alkaline-forming tendency in the body has nothing to do with the actual pH of the food itself. For example, lemons are very acidic, however the end-products they produce after digestion and assimilation are very alkaline so lemons are alkaline-forming in the body. Likewise, meat will test alkaline before digestion but it leaves very acidic residue in the body so, like nearly all animal products, meat is very acid-forming.
