简要总结
This study examined whether dietary-induced reductions in lipoprotein-associated phospholipase A2 (Lp-PLA2) activity in peripheral blood mononuclear cells (PBMC) and plasma affected metabolic profiles in PBMCs and plasma.
详细描述
Eighty nonobese patients (aged 40-70 years) with prediabetes or newly diagnosed type-2 diabetes were randomly assigned to a control group (normal diet with refined rice) or a whole-grain group (replacement of refined rice with whole-grains and legumes). This dietary intervention replaced approximately 7% of carbohydrate-derived energy with approximately 4% of protein-derived energy and approximately 3% of fat-derived energy.
