简要总结
Self-reported healthy participants (n=150) aged 30-65 years with 18.5 kg/m^2 ≤ BMI < 30 kg/m^2 were randomly assigned into three groups: a low linoleic acid (LA, 18:2n-6) group (n=50) replaced 10 mL soy oil with one apple; a medium LA group (control group, n=50) maintained usual food intake; a high LA group (n=50) reduced 1/3 cup of cooked refined rice and consumed 9.9g of soy oil capsules daily as a supplement. Plasma fatty acids and lipoprotein-associated phospholipase A2 (Lp-PLA2) activity were measured at baseline and 8 week alongside other cardiovascular disease risk factors.
