Table 2.

The percent change of area under curve (AUC) of oxidative stress biomarkers in older adults after acute intake of 250 mg (L) or 450 mg (H) almond skin polyphenols (ASP) or skim milk (C) ¹.

ASP	Plasma MDA	Plasma ISOPROSTANES	Lag Time of LDL Oxidation	Lag Time of LDL Oxidation with α-Tocopherol 2
	AUC (%∙h) 3
C	954 ± 56	948 ± 125	973 ± 18	1031 ± 44 a
L	-	-	1010 ± 26	1369 ± 152 b
H	993 ± 70	1154 ± 198	990 ± 18	1364 ± 108 b

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 α-Tocopherol (6 µmol/L) was added to LDL before the initiation of oxidation; 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.
