This is what I wrote:
Human nutrition in relation to daily
dietary phosphorus intake must be closely assessed due to the Ca and Mg
metabolism. Potentially contributing to osteoporosis, dietary P intake may
affect the absorption and metabolism. Requiring phosphorylation, P is an
essential element for energy metabolism.
Several methods are available for the
assessment of daily dietary intake (DDI) of phosphorus (P). While several methods may be available to
test this, very few studies have been carried out to confirm or deny this.
108 hospital meals were evaluated using
spectrophotometric analysis. Duplicate portion sampling, 24 hour daily recalls
for 3 days (150 questionaires) and
Food composition tables were also used.
Photospectrometer showed DDI of P was
significantly lower (P <0.001) than the other two methods. This is closer to DRI for 14 to 18 year old
subjects and adults than the other two methods.
Food composition tables over estimated DDI of P. Cooking processes and
effects on the P content of such foods was most reliable with duplicate portion
sampling.
As DDI mean values were noted as 1106+221,
1480+221 and 1515+223 mg/d.
Adverse effects in relation to P nutrition
were not noted within toxicity or deficiency.
I'll let you know the scores :)
