Amino acid mixtures corresponding to either casein or egg yolk protein when fed to rabits ina low fat, cholesterol-free semipurified diet, produced the same degree of hypercholesterolemia as the proteins themselves. Amino acid mixtures corresponding to soy protein isolate or sunflower protein gave low plasma cholesterol levels, but not as low as those obtained with the intact proteins. Experime...

The effects of dietary soy protein compared to casein were examined in male and female CD1-pcy/pcy (pcy) mice with polycystic kidney disease. Animals 10 wk of age were fed purified diets containing either soy protein isolate or casein given at a level of 17.4 or 6% protein. After 13 wk on the diets, body weights and serum concentrations of albumin and protein indicated that protein nutrition wa...

objective: to ascertain the effects of soy [in the forms of textured soy protein (tsp) and soy-nut] on lipid profiles, apolipoproteins, inflammatory and prothrombotic markers and blood pressure in elderly women with the metabolic syndrome. materials and methods: the study is a 12-week parallel randomized controlled trial that was conducted in rural health centres of babol, iran. the participant...

Isolated soy-protein products are useful for food ingredients because they provide solubility, water binding, fat adsorption, emulsification, viscosity, gelation, foaming, adhesion and cohesion, texturization, and flavor formation. Soy-protein concentrates (SPCs) and soy (SPIs) are the representative soy Conventionally, SPCs and SPIs have been produced by removing non-protein portions such as o...

BACKGROUND Resistance exercise leads to net muscle protein accretion through a synergistic interaction of exercise and feeding. Proteins from different sources may differ in their ability to support muscle protein accretion because of different patterns of postprandial hyperaminoacidemia. OBJECTIVE We examined the effect of consuming isonitrogenous, isoenergetic, and macronutrient-matched soy...

Consumption of soy protein has been associated with altered risk of developing endocrine-regulated cancers. This study was designed to assess the independent effect of soy relative to animal protein and soy-derived isoflavones on circulating estrogen and androgen concentrations in postmenopausal women and older men. Forty-two subjects (> 50 yr) with low-density lipoprotein cholesterol levels of...

High-moisture extrusion of soy protein isolate generates a highly palatable meat substitute. No systematic evaluation of the nutritional quality of soy processed in this manner has been performed. This study compared the growth rate of male and female mice fed diets containing soy protein isolate without extrusion or with high-moisture extrusion. Other measures of overall growth and animal heal...

The physicochemical and sensory properties of peanut spreads fortified with soy flour were studied. Peanut spreads were replaced by whole soybean flour and soy nut flour at 0, 5, 15, 20 and 30% (w/w). All samples were analyzed for fat, protein, sugar, moisture content, adhesiveness, cohesiveness, hardness and sensory characteristics. Replacing peanut spread with soy flour had significant effect...

OBJECTIVE Non-alcoholic steatohepatitis (NASH) is a common cause of liver disease, and it may progress to fibrosis or cirrhosis. The aim of this study was to investigate the effects of soy protein on hepatic steatosis and insulin resistance in NASH. METHODS Forty male Sprague-Dawley rats were fed a high-fat diet for 4 wk to induce NASH and then were allocated to one of four diets: a NASH-indu...

The effect of dietary soy on cardiovascular disease risk factors has been a topic of intense scientific and public interest over the past 10 or more years—a topic that was brought to the forefront by Anderson’s 1995 meta-analysis that highlighted clinical studies from the previous 20 y (1). The originally reported magnitude of the hypocholesterolemic effect of soy protein (9.3% decrease in tota...
