Summary: In a cross-sectional study involving 406 Chinese adults aged

40-65 years, results indicate that greater habitual soyfood

consumption may be associated with a decreased bifurcation carotid

intima-media thickness (IMT) and improved lipid profile, particularly

in men. Among men, after adjusting for potential confounders, the

third tertile for habitual soyfood consumption (mean = 7.48 g/d soy

protein) was associated with lower mean bifurcation IMT (16%), total

cholesterol (12.3%) and LDL cholesterol (19.6%), compared with the

first tertile (mean = 0.64 g/d soy protein). Similarly, among women,

the third tertile for habitual soyfood consumption (mean = 8.35 g/d

soy protein) was associated with lower mean bifurcation IMT (9.4%),

total cholesterol (6.2%) and LDL cholesterol (10.4%), compared with

the first tertile (mean = 0.64 g/d soy protein). The association

between habitual soyfood intake and IMT and total and LDL cholesterol

was stronger in men. Thus, the authors of this stu dy conclude,

" higher habitual soyfood consumption is associated with decreased

bifurcation IMT, plasma TC and LDL-c in middle-aged Chinese adults.

The association is more apparent in men than in women. "
