Although the beneficial effects of Mediterranean-type diets, which are rich in olive oil, a good source of monounsaturated fatty acids (MUFAs), are generally accepted, little is known about the effects of long-term dietary MUFA intake on postprandial lipoprotein metabolism and hemostasis. This study used a single-blind, randomized, crossover design to(More)
Postprandial lipaemic responses to two test meals were investigated in 30 Northern (15 British and 15 Irish), and 30 Southern (Greeks from Crete) healthy male Europeans. The meals were a saturated fatty acid (SFA) meal, which resembled the fatty acid composition of an average UK diet, and a monounsaturated fatty acid (MUFA) meal in which the fat consisted(More)
Le GIP (polypeptide insulinotropique dependant du glucose) et le GLP-1(7-36)amide (forme tronquee biologiquement active du peptide 1 semblable au glucagon) sont tous deux des hormones de la muqueuse intestinale, situtes respectivement dans l’intestin gCle proximal, et dans l’intestin grCle distal et le d o n . Aussi bien le GIP que le GLP-1(7-36)amide sont(More)
The direct actions of glucose-dependent insulinotropic polypeptide, glucagon-like peptide-1(7-36)amide and insulin on lipoprotein lipase activity in explants of rat epididymal adipose tissues were investigated. Lipoprotein lipase was extracted into the incubation medium by heparin release of lipoprotein lipase and measured by fatty acid release from a(More)
The extent and duration of postprandial lipaemia have been linked to risk of CHD but the influence of dietary variables on, and the relative contributions of, exogenous (chylomicron) and endogenous (VLDL) triacylglycerols to the total lipaemic response have not been comprehensively evaluated. In the present study the triacylglycerol, apolipoprotein (apo)(More)
1. The effect of chronic saccharin (benzosulphimide) consumption on glucose homeostasis was examined in normal lean +/+ mice and genetically obese hyperglycaemic insulin-resistant ob/ob mice. 2. Consumption of a 5% (w/v) sodium saccharin solution for 7 weeks prevented the development of hyperglycaemia, improved glucose tolerance (area under curve decreased(More)
Plasma concentrations of glucose dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1(7-36)amide (GLP-1[7-36]amide) were measured after milk ingestion in 15-18 day old piglets and after weaning diet ingestion in 33 day old piglets weaned at 21 days. Intestinal concentrations of these two hormones were also measured in unsuckled piglets of(More)
BACKGROUND This study was an extension of a previous study that showed different lipemic responses to standard test meals in subjects from southern and northern Europe. OBJECTIVE The aim was to determine in 32 healthy young men from northern and southern Europe whether differences in the secretion of insulin and glucose-dependent insulinotrophic(More)
Investigation of nutrient stimulation of two gut hormones GIP (glucose dependent insulotropic polypeptide) and GLP-1(7-36)amide (the active truncated form of glucagon-like peptide-1) is made difficult by the differential control of gastric emptying. Direct nutrient infusion into the duodenum was therefore carried out on three female pigs. The infusates(More)
