This study evaluated the hypolipidaemic and antioxidant effects of soy and Camellia sinensis (green tea) alone and/or in association in dyslipidaemic subjects. One hundred dyslipidaemic individuals were allocated into four groups. The soy group ingested 50 g of soy (kinako) daily, and the C. sinensis group ingested 3 g of C. sinensis in 500 ml of water per day. A third group ingested 50 g of soy and 3 g of C. sinensis daily, and the control group had a hypocholesterolaemic diet. Evaluations were performed at baseline and after 45 and 90 days. Plasma levels of total cholesterol, HDL-C and triacylglycerols were evaluated by automated methods. LDL-C was calculated using the Friedewald equation. The results were expressed as median values and their 25th to 75th percentiles, with a 5% level of significance. No significant difference occurred in LDL-C, HDL-C and triacylglycerol levels across groups. However, a statistically significant difference in total cholesterol occurred within the soy/C. sinensis group 45 and 90 days after intervention. No statistically significant difference occurred in plasma levels of lipid hydroperoxides or those linked to LDL in any of the groups studied. All the groups that used soy and/or C. sinensis presented increased total plasma antioxidant potential.
