Postprandial Plasma Essential Amino Acid Concentration Incremental Area-under-the-curve [ Time Frame: 360 Minutes]Primary· 6 hours after consumption of intervention
Free leucine, isoleucine, valine, histidine, lysine, methionine, phenylalanine, threonine, tryptophan (combined) (µmol·L\^(-1)·min). Following time points (in minutes) post-ingestion will be used to calculate the incremental area under the curve: 60, 90, 120, 180, 210, 240, 270, 300, 330, 360.

Sponsor's own description
Several of the investigator's recent studies have shown that all dietary proteins are not equal when it comes to making proteins in human bodies. Generally, foods made from animal muscle tissue are much more efficient at making new proteins in the body that those from plant sources. This study will measure the amount of protein growth in participants after consuming either one beef patty, one vegi-burger, or two vegi-burgers. By using stable isotope infusions and collecting blood and leg muscle samples, the investigator's lab can determine the rate of muscle metabolism that happens after a participant eats a protein-containing food. The investigator wants to determine if the vegi-burger is as efficient as the beef patty at creating proteins in a participants. The investigator will measure this metabolism over a 10-hour period, with the food being eaten at the 4 hour mark. The investigator plans to perform this procedure on up to 8 participants per food option (24 total).
