Abstract: Background : Many studies suggest that dark chocolate consumption has beneficial effects on metabolic syndrome components in general population. However, there is no data in pregnant population. Objectives : Study the effects of the consumption of chocolate rich in flavanols and theobromine on metabolic syndrome components in pregnant women at risk of preeclampsia. Methods : 131 pregnant women at risk of preeclampsia were randomized in the experimental group (HFHT chocolate) or in the control group (LFLT chocolate). These women had to eat 30g of chocolate every day for 12 weeks. Measures of blood pressure (BP), serum lipids, blood sugar, insulin and weight were done at the randomization visit and repeated at week 12. Results : No significant group by time interaction was found in fasting glucose and fasting insulin concentrations after 12 weeks of chocolate consumption. A significant time effect was observed in fasting insulin concentrations in both HFHT and LFLT chocolate groups (p<0.0001), with similar increases in fasting insulin concentrations at 12 weeks. A significant group by time interaction was observed for triglyceride concentrations (p=0.006), with a more pronounced deterioration in the LFLT group. Significant time effects were observed in total-C, LDL-C, HDL-C and total-C on HDL-C ratio (p< 0.0001), with similar increases in both HFHT and LFLT chocolate groups. A significant group by time interaction was noted for body weight (p=0.03), with a greater weight gain in the LFLT group. Conclusion : Results suggest that consumption of HFHT chocolate could have beneficial effects on triglyceride concentrations in pregnant women. Our results also suggest that HFHT chocolate consumption during pregnancy in women at risk of PE does not conduct to more beneficial effect on fasting glucose concentrations compared to LFLT chocolate group.
