To examine dietary intakes in relation to long-term serum lipoprotein changes in a prospective cohort study with 7 y of follow-up, serum lipids were analyzed by enzymatic methods, while food intake was calculated from validated food frequency questionnaires. First-and second-generation Japanese-Brazilians (n=316) living in Bauru, Sao Paulo/Brazil, of both genders, aged 40 to 79 y were assessed at baseline in 1993. Multiple linear regression models were used with changes in serum lipoproteins as the dependent variable and changes in dietary intakes as the independent variables, adjusted for confounding factors. In energy-adjusted analyses, changes in serum total cholesterol were inversely associated with changes in total dietary fiber, fruits/fruit juices and vegetables after adjustment for age and gender. Each increase of 10g in the consumption of total dietary fiber was associated with a reduction of 12.5mg/dL in the serum total cholesterol (p<0.05). Our results highlight the importance of increased intakes of total fiber, fruits and vegetables to prevent and control dyslipidemia in Japanese migrants.
