Table 1.
The percent change of area under curve (AUC) of plasma glutathione, glutathione peroxidase activity, and oxygen radical absorbance capacity (ORACpca) in older adults after acute intake of 250 mg (L) or 450 mg (H) almond skin polyphenols (ASP) or skim milk (C) 1. GPx: glutathione peroxidase.

1 Values are mean ± SEM, n = 7. a,b Means in the same column not sharing the same letter differ, p ≤ 0.05, using an ANOVA t-test, followed by Tukey’s HSD test. 2 Plasma was treated with perchloric acid (PCA) first before testing by ORAC assay. 3 Percent change from the respective baseline value (0 h) of each visit is calculated to construct the area under the curve (AUC) using the linear trapezoidal integration.
