The Claim

Among hypercholesterolemic adults over age 50, consumption of soymilk for six weeks results in a 1% increase in HDL cholesterol and a 2% increase in apolipoprotein A-I compared to diets based on whole soybeans or soy flour, but not compared to animal protein, indicating that the form of soy protein influences HDL-related markers independently of total protein source.

Cause and effect

In plain English

In adults over 50 with high cholesterol, drinking soymilk for six weeks raises HDL cholesterol by 1% and apolipoprotein A-I by 2% compared to eating whole soybeans or soy flour, but not compared to eating animal protein, showing that the form of soy protein affects these markers regardless of total protein intake.

See the scientific wording

Among hypercholesterolemic adults over age 50, consumption of soymilk for six weeks leads to a 1% increase in HDL cholesterol and a 2% increase in apolipoprotein A-I compared to diets based on whole soybeans or soy flour, but not compared to animal protein, suggesting that the form of soy protein may influence HDL-related markers independently of total protein source.

Why this might work

The liquid form of soy releases compounds that signal the liver to make more of a protein that builds good cholesterol particles, leading to higher levels in the blood.

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

    For people with high cholesterol, drinking soymilk for six weeks slightly raised good cholesterol and a related protein more than eating soybeans or soy flour, but not more than eating meat or dairy — meaning how the soy is processed matters for these specific health markers.
