FIGURE 2.

Postprandial plasma concentrations of pooled amino acids. (A) TAAs. (B) BCAAs. (C) EAAs. (D) NEAAs. (E) NPAAs. Markers indicate means ± SEMs (n = 29); note the difference in vertical scales. The test meal groups contained either pasture-raised beef (Pasture), grain-finished beef (Grain), pasture-raised lamb (Lamb), or Beyond Burger (BB; Beyond Meat). A significant effect of time was observed for all pooled classes, and interactions with meal groups occurred for TAAs, BCAAs, EAAs, and NPAAs. Post hoc pairwise comparisons by Tukey's test (P < 0.05) are as follows: ^aBetween Pasture and Grain, ^bBetween Pasture and Lamb, ^cBetween Pasture and BB, ^dBetween Grain and Lamb, ^eBetween Grain and BB, ^fBetween Lamb and BB. BCAA, branched-chain amino acid; EAA, essential amino acid; NEAA, nonessential amino acid; NPAA, non-proteogenic amino acid; TAA, total amino acid.
