15 outpatients with type II hyperlipoproteinemia (7 with type IIa and 8 with type IIb) were treated with soybean. This diet induced a significant decrease of plasma cholesterol levels from 314 +/- 24 to 267 +/- 30 mg/100 ml. ⋯ In our efforts to reduce hyperlipidemia the very low cost of these vegetable proteins is a further advantage. The hypocholesterolemic mechanism of soybean diet is unknown.
