This study provides an opportunity to find effects of high-legume diet on CVD risk factors in women who consumed high legumes at baseline.</p> <p class="abstract"><strong>METHODS:</strong> This randomized controlled trial was undertaken in 34 premenopausal women with central obesity. After 2 weeks of a run-in period on an isocaloric diet, subjects were randomly assigned into two groups: (1) hypocaloric diet enriched with legumes (HDEL) (n = 17) (two servings per day) and (2) hypocaloric diet without legumes (HDWL) (n = 17) for 6 weeks. The following variables were assessed before intervention, 3, and 6 weeks after it: Waist to hip ratio (WHR), total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C), high-sensitive-C-reactive protein (hs-CRP), total antioxidant capacity (TAC), nitric oxides (NO_x), and Malondialdehyde (MDA).</p> <p class="abstract"><strong>RESULTS:</strong><strong> </strong>Both hypocaloric diets reduced hs-CRP in 3 weeks and returned it to basal values after 6 weeks (P<em> </em>= 0.004). HDWL significantly reduced WHR [P<em> </em>= 0.010 (3.2%)] and increased TC [P &lt; 0.001 (6.3%)]. Despite the significant effect of HDEL on increasing TAC in 3 weeks <br /> [P = 0.050 (4%)], the level of TAC remained the same in 6 weeks. None of the diets had any significant effects on NO_x and MDA.</p> <p class="abstract"><strong>CONCLUSION:</strong> The study indicated that beneficial effects of legumes on TC, LDL-C, and hs-CRP were achieved by three servings per week, and consuming more amounts of these products had no more advantages.</p> <p class="abstract">&nbsp;</p></div><p class="abstract">&nbsp;</p></div>
