Sodium (Na), potassium (K), calcium supplements (Ca), phosphorus (P), magnesium (Mg) and you will zinc (Zn) balance have been read for a few successive weeks having fun with four healthy, men sufferers within their twenties. Based on the result of the analysis, the newest relationship within consumption profile and excretions in feces and you can urine or solution concentrations is analyzed.1) Regarding balance analysis, new taken Na, K and P was basically generally excreted for the pee. The new excretion rates when you look at the pee because the up against the consumption is large to possess Na at the 85%, followed closely by 84% getting P and you can 74% getting K. Having said that, California, Mg and Zn have been excreted during the stool during the highest cost, excretions Columbia escort service into the pee are only 38% having Ca, 25% for Mg and you will 7.1% for Zn.2) Analysis of your own relationship involving the intake and you can removal into the feces showed that only K presented an optimistic correlation that have analytical relevance.3) Na (r=0.974) and K (r=0.891) demonstrated statistically extreme confident relationship involving the intake and excretion from inside the urine.4) There can be no statistically tall relationship between the consumption and you will serum intensity of these minerals.5) Of strategies for quoting consumption quantities of Na, K, Ca, P, Milligrams and you will Zn off their excretions from inside the pee and stool and you will serum levels, estimation from urinary chlorine is famous. Today’s studies revealed that excretions regarding Na and you may K inside twenty-four hour urine are used in estimating brand new consumption accounts ones nutrients.
