Outline of Final Research Achievements

We constructed a multicenter prospective cohort of patients with obesity and diabetes and found (1) exacerbation of inflammatory properties of monocytes/carotid plaque by diabetes, (2) relationship of the adipose tissue-derived product, TSP-1, with the visceral fat obesity-related diseases, (3) positive association of the intake rate of soy products with the adiponectin level, (4) positive association of the serum ratio of eicosapentaenoic acid (EPA) to arachidonic acid with the adiponectin level, and (5) anti-inflammatory effects of EPA on cerebral macrophages. We also showed the reduction of LDL-C and CAVI, an indicator of atherosclerosis, by administration of soy bean-metabolites of enterobacteria, and the LDL-C reduction was positively correlated with the CAVI reduction. Our findings should contribute to the establishment of effective nutrition guidance to reduce risk for cardiovascular diseases by focusing on the lipid quality and intestinal flora.
