Abstract

The purpose of this study was to investigate the effect of feeding dietary soy protein and soy protein supplemented with methionine on lipids and lipoproteins content of blood in wistar rats. Sixteen male and 16 female wistar rats with the initial live weight of 116 ± 6.3 and 115.8 ± 6.8 grams respectively, were fed by the isocaloric and isonitrogenous diets containing casein (20%), soy protein (28%), soy protein (27%) supplemented with methionine (0.3%) and soy protein (14%) plus casein (10%) for 8 weeks. Soy-methionine fed animals performed higher average live weight gain in comparison with the other groups (p
