Abstract
This study examined if plant sterols and walking reduce postprandial triacylglycerol (TAG) concentrations in Chinese men with elevated body mass index (≥ 23.5kg/m2). Fifteen Chinese men (mean [SD]: age = 25 [3] years and body mass index = 26.2 [1.5]kg/m2] completed four 10-day trials in random order with a 7- to 10-day washout between trials: (a)daily consumption of a control margarine while sedentary (C-S), (b)daily consumption of margarine containing 2g/day of plant sterols while sedentary (PS-S), (c)daily consumption of a control margarine with 30-min daily walking (C-W), and (d)daily consumption of margarine containing 2g/day of plant sterols with 30-min daily walking (PS-W). On Day 11 of each trial, postprandial TAG was measured after a high-fat milkshake. The 5-hr total area under the TAG curve was 22%, 25%, and 12% lower on PS-W (mean [SD]: 8.9 [4.3] mmol·5hr/L) than C-S (11.4 [4.5]mmol·5hr/L; p = .005; d = 0.56), PS-S (11.9 [4.9] mmol·5hr/L; p = .004; d = 0.67), and C-W (10.1 [4.4]mmol·5hr/L; p = .044; d = 0.27) trials, respectively. Similarly, 5-hr incremental area for PS-W (4.5 [2.7]mmol·5hr/L) was 31%, 32%, and 18% lower than C-S (6.6 [3.3]mmol·5hr/L; p = .005; d = 0.62), PS-S (6.6 [3.4]mmol·5hr/L; p = .004; d = 0.64), and C-W (5.5 [2.8]mmol·5hr/L; p = .032; d = 0.29). Ten days of daily plant sterol intake combined with walking presents an intervention strategy to lower postprandial TAG in Chinese men with elevated body mass index.
Highlights
This study examined if plant sterols and walking reduce postprandial triacylglycerol (TAG) concentrations in Chinese men with elevated body mass index (≥ 23.5 kg/m2)
Plant sterols (PS) can reduce low-density lipoprotein cholesterol (LDL-c) at intakes of ∼2 g/day (Catapano et al, 2016; Gylling et al, 2014), but accumulating evidence implicates them in the reduction of fasting triacylglycerol (TAG), with greater reductions seen in individuals with higher TAG (Demonty et al, 2013; Gylling et al, 2014)
PS with 30-min daily walking (PS-W) was 22%, 25%, and 12% lower than control margarine while sedentary (C-S) (d = 0.56, 95% confidence intervals (CIs) [−0.189, −0.041]), PS while sedentary (PS-S) (d = 0.67, 95% CI [−0.213, −0.049]), and control margarine with 30-min daily walking (C-W) (d = 0.27, 95% CI [−0.114, 0.009]), respectively
Summary
Plant sterols (PS) can reduce low-density lipoprotein cholesterol (LDL-c) at intakes of ∼2 g/day (Catapano et al, 2016; Gylling et al, 2014), but accumulating evidence implicates them in the reduction of fasting triacylglycerol (TAG), with greater reductions seen in individuals with higher TAG (Demonty et al, 2013; Gylling et al, 2014). Aerobic exercise reduces fasting (Kraus et al, 2002) and postprandial TAG (Maraki & Sidossis, 2013). Given both exercise and PS modify TAG, surprisingly only one study has examined their combined benefits noting reductions in fasting TAG along with LDL-c, but the effects were not additive or synergistic compared with the treatments in isolation (Varady et al, 2004). We are unaware of any studies examining how PS and exercise combined impact postprandial TAG.
