Seventy-two Yorkshire boar pigs were used to study growth rate and feed efficiency in pigs weaned at 3 weeks of age and fed either casein or soy-protein as a source of supplemental protein in corn based diets. Treatments consisted of a corn-casein diet, a corn-isolated soy protein diet, a corn-ethanol extracted soy protein diet and a corn soybean meal diet. Feed intake was not affected by sourc...

Vegan protein-based diet has attracted increasing interest in the prevention of metabolic syndrome (MetS). Meanwhile, adiponectin has become a highly potential molecular target in the prevention of MetS. Our study will identify a potential vegan protein diet for the prevention of MetS using rat models. Thirty-six Wistar rats were randomly assigned into three groups and given diets containing on...

INTRODUCTION It has been suggested that soy protein can slow renal disease progression by decreasing plasma cholesterol and proteinuria in patients with nephropathies. This study was designed to evaluate the effect of soy protein on proteinuria and dyslipidemia, in patients with proteinuric glomerulopathies. PATIENTS AND METHODS Patients were divided into three groups: Control Group (n = 9) r...

Soybeans is an important crop in the United States and are primarily used for animal feed, human food, and production of biofuels. Soybean meal (SBM) and other soy products contribute high-quality protein to diets fed to pigs because soy protein is rich in the limiting amino acids lysine, threonine, and tryptophan that are present in relatively low concentrations in the most commonly fed cereal...

BACKGROUND Many of the benefits of soy have been attributed to soy isoflavones. OBJECTIVE The objective was to determine the effects of high- and low-isoflavone soy-protein foods on both lipid and nonlipid risk factors for coronary artery disease (CAD). METHODS Forty-one hyperlipidemic men and postmenopausal women participated in a study with three 1-mo diets: a low-fat dairy food control d...

Soy-protein formulas are widely used for feeding babies with cow-milk allergy. When they first were marketed, these formulas were the only available cow-milk substitute and they ensured a normal life for many children who were affected by the large spectrum of clinical manifestations of cow-milk allergy. Soy-protein formulas were also given to allergy-prone infants for the prevention of atopic ...

Soy foods have been reported to have protective effects against premenopausal breast cancer in Asian women. No studies have been reported on potential physiological effects of dietary soy consumption on breast gland function. We evaluated the influence of the long-term ingestion of a commercial soy protein isolate on breast secretory activity. We hypothesized that the features of nipple aspirat...

Two trials were conducted to determine the suitability of soybean products for baby pigs. Weanling pigs (n = 40 and 48 in Trials 1 and 2, respectively) were infused orally (6 g/d) with dried skim milk, soybean meal (SBM, 48% CP); soy protein concentrate, moist extruded soy protein concentrate, or soy protein isolate from d 7 to 12 of age. Pigs were then fed a diet containing the same protein so...

In the present studies, several hypotheses were tested to explain previously reported differential effects of soy and casein on colon cancer biomarkers like cell proliferation, fecal fat, fecal bile acid, alkaline phosphatase, and magnesium excretion in rats. In Study 1, the effect of methionine, a limiting amino acid in soy protein and an amino acid that is thought to have a marked effect on c...

BACKGROUND Diet is a major factor influencing the composition and metabolic activity of the gut microbiota. OBJECTIVE This study investigated the effect of soy compared with dairy protein on the gut microbiota of hamsters to determine whether changes in microbiota could account for soy protein's lipid lowering properties. METHODS Thirty-two 6- to 8-wk-old, male Golden Syrian hamsters were f...
