Markedly increased concentrations of free fatty acids after a fatty meal and heparin injection already have been shown to falsely increase thyroxine values measured by competitive protein-binding techniques, where ethanol extraction in used. We report here the effect of lesser increases. In 10 patients receiving heparin during hemodialysis we found significant increases in serum thyroxine by co...

Administration of a single 1 g dose of neomycin sulfate to five healthy subjects simultaneously with a test meal caused a marked increase in the proportion of fatty acid and bile acid in the ultracentrifuged deposit of aspirated intestinal contents. Labeled cholesterol was precipitated in a similar manner in two hypercholesterolemic patients. Neomycin had no effect on the pancreatic lipase conc...

Introduction: Eating fatty food is a common technique for decreasing extra cardiac activity, but sometimes patients refuse to eat fatty foods due to various reasons during myocardial perfusion imaging. The aim of this study is to introduce an alternative method for patients who are not able to use fatty foods to accelerate the transit of radiotracer from the liver. <stron...

Obesity and lipid metabolism abnormalities are associated with numerous non communicable diseases such as metabolic syndrome, type2 diabetes, arthrosclerosis, fatty liver diseases, infertility etc. Modern life style choices such as consumption of high caloric diet and sedentary living conditions are implicated in the pathogenesis of these diseases. Most of the currently available drugs for thes...

1. Healthy male volunteers consumed at noon, hot test meals with four different carbohydrate:fat ratios varying between 2.64 and 0.50, and composed of fried beefsteak, mashed potatoes, French beans, and a dessert of custard with mashed peaches. The energy content of the meals was 40% of the daily intake of the volunteers, estimated from their individual dietary histories. 2. Before, and at diff...

In the present study, the authors measured vascular functioning of the forearm of 25 male subjects via ultrasound (Doppler imaging) at time zero and after 4 hours after consuming a high-fat meal. Using a single-blinded crossover design, the subjects either consumed a placebo oil (no DHA/EPA present) or fish oil (providing a total amount of DHA/EPA amounting to 5.4 grams-3.24 grams DHA plus 2.16...

BACKGROUND Postprandial lipemia is markedly modulated when carbohydrates are added to a fatty meal. The effect of added protein is less known, however, and the data are controversial. OBJECTIVE We investigated the effects of casein added to various fat-rich meals in the absence and presence of oligosaccharides. DESIGN Four different test meals were given to 24 healthy volunteers: 1) fat alo...

The majority of the studies that have found a lowering effect of exercise on postprandial lipaemia have employed exercise 12-18 h before a test meal of exaggerated fat content (over 60 % total energy). The aim of the present study was to investigate whether this effect is manifest when exercise is performed immediately before a test meal of moderate fat content. Eleven healthy young men cycled ...

BACKGROUND: Although the effects of resistant starch (RS) on postprandial glycemia and insulinemia have been extensively studied, little is known about the impact of RS on fat metabolism. This study examines the relationship between the RS content of a meal and postprandial/post-absorbative fat oxidation. RESULTS: 12 subjects consumed meals containing 0%, 2.7%, 5.4%, and 10.7% RS (as a percenta...

BACKGROUND Dietary fatty acids that are more prone to oxidation than to storage may be less likely to lead to obesity. OBJECTIVE The aim of this study was to determine the effect of chain length, degree of unsaturation, and stereoisomeric effects of unsaturation on the oxidation of individual fatty acids in normal-weight men. DESIGN Fatty acid oxidation was examined in men consuming a weigh...
