The Claim

In hypercholesterolemic adults over age 50, consuming soymilk as a source of soy protein for six weeks results in a 4% reduction in LDL cholesterol compared to diets containing animal protein or soy flour, when dietary fat, cholesterol, and fiber are held constant.

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

In plain English

Among adults over 50 with high cholesterol, drinking soymilk for six weeks lowers LDL cholesterol by 4% compared to eating animal protein or soy flour, when overall fat, cholesterol, and fiber intake are kept the same.

See the scientific wording

In hypercholesterolemic adults over age 50, consuming soymilk as a source of soy protein for six weeks results in a modest 4% reduction in LDL cholesterol compared to diets containing animal protein or soy flour, when dietary fat, cholesterol, and fiber are held constant, suggesting that the form of soy protein may influence lipid profiles even when overall diet quality is controlled.

Why this might work

When soymilk is consumed, the soy protein in its liquid form triggers the liver to make more receptors that grab bad cholesterol from the blood and pull it inside the liver to be broken down, which lowers the amount of bad cholesterol circulating in the body.

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

    This study found that when people with high cholesterol drank soymilk instead of other soy products for six weeks, their bad cholesterol went down a little — about 4% — even when everything else they ate stayed the same. So yes, the type of soy product matters.
