|Soy Protein May Reverse Atherosclerotic Progression|
|Published Thursday, December 1, 2005|
N.C.--Long-term supplementation with soy protein appears to reduce the
size of atherosclerotic plaques without affecting reactivity of the
coronary artery (J Nutr,
135:2852-6, 2005). Researchers from the Wake Forest University School
of Medicine conducted a 31-month study in adult male monkeys to
determine the impact of atherogenic diets with different protein
sources. The diets included a low-isoflavone soy protein isolate (0.94
mg isoflavones/g protein) diet, a high-isoflavone soy protein isolate
(1.88 mg isoflavone/g protein) diet, and a control (casein/lactalbumin)
Compared with control, both soy protein groups showed reductions in plasma low-density lipoprotein (LDL) cholesterol and increases in high-density lipoprotein (HDL) cholesterol and apolipoprotein A-1. In addition, both soy protein groups showed a reduction of approximately 34 percent in atherosclerosis, as judged by mean plaque size in the coronary arteries. The soy diet did not impact endothelium-dependent or -independent arterial reactivity.
