Angiopoietin-Like Protein Responses to Pecan-Enriched Diets Versus a Nut-Excluded Diet
Liana L. Guarneiri,Chad M. Paton,Jamie A. Cooper 한국식품영양과학회 2022 Journal of medicinal food Vol.25 No.11
Daily pecan consumption improves fasting and postprandial triglycerides, but its effect on angiopoietin-like proteins (ANGPTLs) is unknown. The objective of this study was to investigate the impact of daily pecan consumption for 8 weeks on fasting and postprandial ANGPTL3, −8, and −4. This was an 8-week, randomized, controlled trial with three treatments: two pecan groups and a nut-free control group (n = 16). The ADD group (n = 15) consumed pecans (68 g) as part of a free-living diet, and the SUB group (n = 16) substituted the pecans (68 g) for isocaloric foods from their habitual diet. Fifty-six participants were randomized but nine subjects did not begin or finish the 8-week intervention and/or testing visits. At pre- and post-intervention, a high saturated fat meal was consumed with 3.5 h postprandial blood draws to determine changes in ANGPTL3, −8, and −4. There was a significant suppression in postprandial ANGPTL3 from pre- to post-intervention within ADD and SUB (P = .004 and P = .002, respectively) but not control (ns). There were no other changes within or between groups for fasting and postprandial outcomes. Daily pecan consumption improved postprandial ANGPTL3, which may mediate improvements in lipid metabolism.

A 4-Week Pecan-Enriched Diet Improves Postprandial Lipid Peroxidation in Aging Adults

Pecans are rich in bioactive compounds known to reduce oxidative stress and provide glucoregulatory benefits. Few studies assessing the effect of a pecan-enriched diet on such health outcomes suggest potential improvements tocardiometabolic health; however, this has not been studied in an older adult population. Thus, we aimed to examine the effectof daily pecan consumption for 4-weeks on fasting and postmeal antioxidant status, oxidative stress, and markers of glycemiain healthy aging adults. In this randomized, parallel, controlled trial, 41 healthy adults (50–75 years) either consumed 68 g ofpecans/day (pecan; n = 21) or avoided all nuts (control; n = 20). At pre- (V1) and postintervention visits (V2), blood sampleswere obtained at fasting, and 30, 60, and 120 min following a high saturated fat meal to assess changes in malondialdehyde,which is a measure of lipid peroxidation, total antioxidant capacity (TAC), glucose, and insulin. Across the intervention, therewere no differences in fasting or postprandial TAC, glucose, or insulin for pecan versus control. There was a trend for adifference in fasting lipid peroxidation from V1 to V2 by treatment (P = .06) driven by a slight reduction for pecan versuscontrol (Dpecan: -2.0 – 1.1 vs. Dcontrol: +0.6 – 0.8 lM). In addition, postprandial lipid peroxidation was suppressed at V2 forpecan, and this was different from control (pecan areas under the curve (AUC): 10.6 – 1.3 lM/h to 9.1 – 1.2 lM/h vs. controlAUC: 8.9 – 1.3 lM/h to 9.2 – 1.1 lM/h; P = .03). These findings suggest that a 1 month, pecan-enriched diet is protectiveagainst postmeal oxidative stress. Longer interventions or a diabetic population may be needed to observe glucoregulatorybenefits.
