Hepatic fatty acid oxidation respiration chamber macronutrient composition obesity etomoxir
2016/12/19
Background: The carnitine O-palmitoyltransferase I (EC 2.3.1.21) inhibitor etomoxir inhibits fatty acid oxidation, and hepatic fatty acid oxidation has been suggested to be a metabolic ...
Acute ingestion of a meal rich in n−3 polyunsaturated fatty acids results in rapid gastric emptying in humans
Cholecystokinin glucagon-like peptide 1 postprandial responses breath test chylomicron n− 3 fatty acids polyunsaturated fatty acids gastric emptying women
2016/12/19
Background: n−3 Polyunsaturated fatty acids (PUFAs) have proven benefits for both the development of atherosclerosis and inflammatory conditions. The effects on atherosclerosis may be partl...
Phytosterols that are naturally present in commercial corn oil significantly reduce cholesterol absorption in humans
Phytosterols oils diet cholesterol mass spectrometry deuterium
2016/12/17
Background: Although supplementing the diet with large quantities of phytosterols reduces cholesterol absorption and LDL-cholesterol concentrations, very little is known about the smaller amounts...
Vegetable-borne lutein,lycopene,and β-carotene compete for incorporation into chylomicrons,with no adverse effect on the medium-term (3-wk) plasma status of carotenoids in humans
Carotenoids bioavailability spinach tomatoes antioxidants women
2016/12/17
Background: The results of epidemiologic studies have consistently shown associations between dietary intake or plasma carotenoid status and incidence of cancers and cardiovascular and eye diseas...
Contribution of dietary protein to sulfide production in the large intestine: an in vitro and a controlled feeding study in humans
Sulfide meat protein sulfur amino acids, fermentation urinary sulfate fecal sulfide intestinal bacteria men
2016/6/8
Background: Hydrogen sulfide is a luminally acting, bacterially
derived cell poison that has been implicated in ulcerative colitis.
Sulfide generation in the colon is probably driven by dietary
com...
