Alterations in Urine pH With Differing Diet Net Acid Loads
Presently, the gold standard for testing diet acid intake is a urine collection done for
many hours, usually 24 hours, which must be analyzed in a research lab for "net acid
excretion". So, getting information about diet acid intake is difficult. Many people have
suggested doing a much simpler test, which is checking the pH of the urine when you wake up.
But, no one has studied if this simpler method is a valid method for estimating the 24 hour
net acid excretion. Diet acid load may be important in many diseases associated with aging,
such as loss of bone and muscle, and the development of kidney disease.

the primary outcome variable is morning urine pH and 24 hour urine net acid excretion
