Study Summary
The specific hypothesis is that the consumption of 2 Hayward green kiwifruit (containing actinidin protease) prior to 100g of ground beef will increase the rate of protein digestion from the beef in the elderly, leading to an increased uptake of the essential amino acids. Furthermore, this increased essential amino acid availability will produce a greater postprandial net anabolic protein response, as well as increased fractional synthetic rates of muscle proteins.
Primary Outcome
Blood samples were analyzed to quantify the appearance of the stable isotopes: 2H2-tyrosine, 2H4-tyrosine, and 2H5-phenylalanine in tracer to tracee ratio or mole percent excess. Changes in these markers over time enable the calculation of whole body protein metabolism. Calculations are done as follows: Total plasma rate of appearance = infusion rate/enrichment Fractional rate of appearance of tyrosine from phenylalanine= 2H4-tyrosine/2H5-phenylalanine Phenylalanine hydroxylation = fractional r
