Determination of total fat, saturated fat, monounsaturated fat and trans fat content in food samples is necessary for complying with applicable food labeling requirements. A typical procedure for saponifi cation of the sample involves refl uxing with sodium methoxide in methanol, followed by a second refl ux with boron trifl uoride in order to esterify the free fatty acids. Prior to injection i...

Using gas chromatography (GC), 10 collaborating laboratories measured total, saturated, and monounsaturated fats in 8 blind duplicate pairs of foodstuffs. The method involves a hydrolysis/ether extraction of fat followed by quantitative GC analysis versus an internal standard. Calculations were designed to comply with federal regulations as specified in the Nutrition Labeling and Education Act ...

Research on the effects of dietary fat on cholesterolemia and coronary risk began with comparisons of the amount and type of fat (saturated vs unsaturated). It then became clear that not all fatty acids had similar cholesterolemic effects and equations were derived which gave different weights to saturated and unsaturated fatty acids. We now find that the triglyceride structure also plays a rol...

Health psychology is the defined as studying of psychological and behavioral processes in health, illness, and healthcare. It contributes to is concerned with the understanding of how psychological, behavioral, and cultural factors contribute role to in physical health and illness. Psychological factors can affect health directly. For example, health is hurt by the chronically occurring environ...

The utility of an automated acid hydrolysis–extraction (AHE) system was evaluated for extraction of fat for the quantification of total, saturated, polyunsaturated, monounsaturated, and trans fat in cereal products. Oil extracted by the AHE system was assessed for total fat gravimetrically and by capillary gas chromatography (GC) for total fat, lipid classes, and trans fat. All AHE system resul...

Important differences in all-causes mortality and in cardiovascular mortality exist between populations and they cannot be explained by differences in the level of medical care. During the last 20 years important changes have occurred in the level of cardiovascular mortality with an increase in Hungary and a decrease in Japan. These rapid changes in mortality cannot be explained by genetic fact...

2. In the early stage of fat synthesis the fat is more acidic and contains a larger percentage of unsaponifiable substances than at any later period. 3. Until the stage of maximal activity of the mould is attained the actual amounts of both saturated and unsaturated component acids continue to increase, but in the subsequent phase ofthe life of the culture the weight of each of these components...

The aim of the present study was to examine the effect of reducing saturated fat in the diet, or partly replacing it with unsaturated fat, on the serum lipoprotein profile of human subjects. The study had two intervention periods, 8 weeks (phase 1) and 52 weeks (phase 2). In phase 1, total fat was reduced from 31 to 25% energy (polyunsaturated fatty acids (PUFA):saturated fatty acids (SFA) rati...

This study was designed to develop an animal model of alcoholic pancreatitis and to test the hypothesis that the dose of ethanol and the type of dietary fat affect free radical formation and pancreatic pathology. Female Wistar rats were fed liquid diets rich in corn oil (unsaturated fat), with or without a standard or high dose of ethanol, and medium-chain triglycerides (saturated fat) with a h...

The relationship of selected social factors to diet, weight and plasma cholesterol was studied in one control and two treatment towns before and after a 3-year, bilingual, mass-media health education program. Spanish-speaking persons reported higher dietary cholesterol and saturated fat than Englishspeaking participants at baseline, and this remained true after adjusting for the confounding inf...
