Decreased lipoprotein (a) and serum high-sensitivity C-reactive protein levels in male patients with atherosclerosis after supplementation with ginger: A randomized controlled trial

BACKGROUND: Although the antioxidant properties of ginger have been revealed, there is little available information on the effectiveness of ginger on inflammatory disorders such as atherosclerosis. This study was carried out to examine the effect of ginger on improving the complication of atherosclerosis.METHODS: This study was a double-blind, placebo-controlled, randomized clinical trial conducted on patients with atherosclerosis. Participants in the ginger and control groups received ۱۶۰۰ mg of powdered ginger or placebo (wheat flour) in capsules daily for ۸ weeks. Weight, body mass index (BMI), fasting blood sugar (FBS), cholesterol, triglyceride (TG), low-density lipoprotein (LDL), very-low-density lipoprotein (VLDL), high-density lipoprotein (HDL), lipoprotein (a) [Lp(a)], high-sensitivity C-reactive protein (hs-CRP), and total anti-oxidant capacity (TAC) were assessed before and after the intervention.RESULTS: Ginger consumption in the intervention group significantly reduced serum Lp(a) level (۲۷.۲۵ ± ۱.۳۰ ng/ml vs. ۲۳.۵۷ ± ۰.۹۷ ng/ml) (P = ۰.۰۴۰) and also the level of hs-CRP in the intervention group was ۱.۹۰ ± ۰.۳۳ µg/ml and ۱.۲۴ ± ۰.۱۵ µg/ml (P = ۰.۰۱۰) before and after intervention, respectively, but the levels of Lp(a) and hs-CRP were not decreased significantly in the placebo group. The level of TAC in the ginger group was ۰.۷۱ ± ۰.۰۵ mM and after the trial was ۰.۵۷ ± ۰.۰۴ mM (P = ۰.۰۵۰); no significant differences were seen in TAC when ginger was administered at ۱۶۰۰ mg/daily for ۶۰ days. Also the level of Lp(a) and hs-CRP but not TAC reduced significantly in ginger group compared to placebo group after intervention.CONCLUSION: This study showed that ginger had anti-atherosclerosis and anti-glycemic properties associated through a significant decreased Lp(a) and FBS in patients with atherosclerosis supplemented with ginger.
