Working hypothesis and aims: Our preliminary results show that high complex carbohydrate diet (HCCD) has beneficial effect on several markers of inflammation. The aims of this study are to reinforce our preliminary results by measuring the effect of HCCD on additional markers of inflammation (TNFα, IL6) and of endothelial dysfunction (ICAM-1, VCAM-1), and to identify the genes affected by HCCD in monocytes. In addition the aim of this study is to determine whether consumption of omega-3 oil actually increase the anti-inflammatory effect obtained by HCCD.
