Description of intervention(s) / exposure
Treatment: Other - Alpha-cyclodextrin
Treatment: Other - Placebo

Active comparator: Alpha-cycoldextrin - All subjects randomized to receive Alpha-cycoldextrin will orally ingest two tablets containing Alpha-cyclodextrin, with their standardized liquid breakfast (100 micro Ci of \[3H\]triolein and 20 micro Ci of \[14C\]tripalmitin). The tablets will be consumed with 150 ml of still water immediately prior to consuming each meal. Subjects will be observed for a period of 48 hours as an in-patient, and then an additional 24 hours as an out-patient. During this time they will undergo a meal fatty acid metabolism study, through blood and fecal sampling, to assess meal fatty acid oxidation and storage.

Placebo comparator: Placebo - All subjects randomized to receive placebo will orally ingest two placebo tablets with their standardized liquid breakfast (100 micro Ci of \[3H\]triolein and 20 micro Ci of \[14C\]tripalmitin). The tablets will be consumed with 150 ml of still water immediately prior to consuming each meal. Subjects will be observed for a period of 48 hours as an in-patient, and then an additional 24 hours as an out-patient. During this time they will undergo a meal fatty acid metabolism study, through blood and fecal sampling, to assess meal fatty acid oxidation and storage.


Treatment: Other: Alpha-cyclodextrin
Alpha-cyclodextrin (a-CD) is a soluble dietary fiber that has a history of use in foods and as a pharmaceutical excipient. Recently the ability of the fiber to bind to dietary fat has led to further investigation of the possible health benefits of dietary supplementation with this fiber.
