Urine Metabolism

Urine Metabolism

Potassium/Sodium Ratio, (K/Na ratio)

  • Turn-around time = 5 to 7 days.
  • A urine test for diagnosis and monitoring whole foods in your diet.

The amount of potassium and sodium is measured in a random urine specimen and is one of the indicators used to look at the amount of whole foods in your diet. Thousands of years ago, our diet contained much more potassium (K+) than it did sodium (Na+). Today, our diet contains much more sodium than potassium. A ratio of one to one (1.0 on your laboratory results) suggests that you may be getting a reasonable amount of whole foods in your diet. A level of greater than 1.0 could indicate that you are eating a predominately whole food diet. "Whole food" refers to the cellular completeness of a food. If a food retains the same cellular components that it grew with, then it is a whole food. White flour, for example, is only 50% whole because the bran and germ have been milled out. Sugar is less than one percent whole.

Provided that your intestinal digestion and absorption are normal, eating more whole foods is one of the best ways to improve your nutritional status and overall health. Whole foods means eating fruits, vegetables, and whole grains in place of processed foods. Foods naturally higher in potassium than sodium may have a K/Na ratio of 4.0 or more. The ratio for an apple is 150/1.0; unsweetened applesauce is 39/1.0, while a piece of a store-bought apple pie is 0.27/1.0!

When food wholeness and omega-6/omega-3 fatty acid ratios are compared to various diet changes through history, we find the following:

Diet > Ancestral Agricultural Industrial Fast Food
Wholeness 100% 90% 60% 35%
Omega-6/3 1:1 5:1 10:1 20:1

The method for K/Na ratio is by ion selective electrode detection. There is no special patient preparation. A minimum of 1.0 mL of urine is required, collected in a clean plastic container. If not run immediately, place in a plastic transport tube, freeze and ship immediately.
