Soy protein is an important component of soybeans and provides an abundant source of dietary protein. Among the dietary proteins, soy protein is considered a complete protein in that it contains ample amounts of all the essential amino acids plus several other macronutrients with a nutritional value roughly equivalent to that of animal protein of high biological value. Soy protein is unique amo...

Studies in rodents have shown that short-term increases in dietary fat result in fat cell enlargement and insulin resistance. In humans, although high-fat diets have been associated with obesity, little is known about the specific metabolic effects of these diets. In this study we explored possible associations between habitual dietary composition and insulin sensitivity. Twenty-two lean and 23...

T HE relationship of dietary fat to calcium and phosphorus utilization has been reported for the rat b y many investigators (Haldi et al., 1939; French, 1942; Calverley and Kennedy, 1949; Cheng et al., 1949 and Swell et al., 1956). High dietary levels of fat have increased fecal calcium in monogastric animals through the formation of insoluble sQaps.~(Boyd et al., 1932 and Fedde et al., 1960). ...

The factors responsible for the variability in plasma leptin levels observed among individuals with similar body compositions remain unclear. To examine the impact of dietary variables, we compared the changes in leptin levels induced by fasting and dietary fat restriction with the expected decrease following a significant loss in adipose mass. A 21.4 +/- 3.7% weight loss led to a 76.3 +/- 8.1%...

Effects of vitamin E-deficiency, dietary fat (corn oil versus lard), and incubation on ultrastructure of platelets, red and white cells, and on selected biochemical parameters of platelets and plasma were studied. Platelets from vitamin E-deficient rats had no obvious morphological defects, but reticulocytes and lymphocytes had swollen and deformed mitochondria. Fatty acid and glycogen levels o...

BACKGROUND The Chinese population has undergone rapid transition to a high-fat diet. Furthermore, monosodium L-glutamate (MSG) is widely used as a daily food additive in China. Little information is available on the effects of oral MSG and dietary fat supplementation on the amino acid balance in tissues. The present study aimed to determine the effects of both dietary fat and MSG on amino acid ...

We investigated dietary modulation, by energy level and energy source, of two-stage skin tumorigenesis initiated with 7,12-dimethylbenz(a)anthracene and promoted with 12-O-tetradecanoylphorbol-13-acetate in SENCAR mice. Studies comparing the influence of dietary calorie restriction (feeding less carbohydrate and less fat) with diet restriction and with ad libitum control feeding indicated an in...

Two trials that utilized 356 yearling steers were conducted to evaluate the effects of fat sources (3.5% of diet dry matter) in steam-flaked milo finishing diets. Fats differed in fatty acid composition and level of free fatty acids. In Trial 1, soybean oil, tallow and yellow grease were compared to a nonfat control. Feeding fat increased (P less than .05) daily gain, feed efficiency, estimated...

This document attempts to evaluate the strengths of the associations between dietary fat and the genesis of atherosclerosis; the kinds of evidence on which these associations are based; and the risks and benefits caused by changing the quantity and quality of dietary fat in the American diet. The role of dietary fat will be evaluated herein as a factor independent of such other putative dietary...
