The Claim

In hypercholesterolemic adults over age 50, consumption of whole soybeans, soy flour, or soymilk for six weeks, with dietary fat, cholesterol, and fiber held constant, has no significant effect on total cholesterol, VLDL cholesterol, triglycerides, apolipoprotein B, or C-reactive protein compared to animal protein.

Description
1 study reviewed
In plain English

In adults over 50 with high cholesterol, eating soy products like soybeans, soy flour, or soymilk for six weeks does not change levels of total cholesterol, VLDL cholesterol, triglycerides, apolipoprotein B, or C-reactive protein compared to eating animal protein, when fat, cholesterol, and fiber intake are kept the same.

See the scientific wording

In hypercholesterolemic adults over age 50, consumption of whole soybeans, soy flour, or soymilk for six weeks has no significant effect on total cholesterol, VLDL cholesterol, triglycerides, apolipoprotein B, or C-reactive protein compared to animal protein, when dietary fat, cholesterol, and fiber are held constant, indicating that soy protein form does not broadly alter major lipid or inflammatory risk markers.

Why this might work

When people over 50 with high cholesterol eat soy products instead of meat, their liver keeps making the same amount of cholesterol and fat particles, and their blood does not show more inflammation, because the soy protein itself does not change how the liver works or how the body responds to fat in the blood.

1 study

  1. Study: Effect of soy protein from differently processed products on cardiovascular disease risk factors and vascular endothelial function in hypercholesterolemic subjects.

    For adults with high cholesterol, eating soy foods like tofu, soy milk, or soy flour for six weeks didn’t change their bad cholesterol, triglycerides, or inflammation any more than eating meat or dairy — as long as the rest of their diet stayed the same.
