Official Title: Effect of Whole Flaxseeds and Flaxseed Mucilage on Lipid Absorption, Glucose and Insulin Metabolism and Appetite Regulation

Further study details as provided by University of Copenhagen:

Primary Outcome Measures:
  • TAG in chylomicrons
  • serum TAG
  • HDL, LDL and total cholesterol
  • appetite scores
  • ad libium food intake
  • appetite hormone levels

Secondary Outcome Measures:
  • free fatty acid profile
  • plasma glucose
  • plasma insulin
  • meal macronutrient composition
  • meal energy content
  • meal pleasantness

Estimated Enrollment: 18
Study Start Date: October 2006
Study Completion Date: October 2007
Detailed Description:
Randomized multiple crossover trial in 18 healthy males aged 18 to 40 years each are required to complete a total of five iso-caloric meal tests lasting approximately 8½ hours. Test meals will be given as breakfast meals, in which different fractions of flaxseeds are incorporated into baked products. Appetite will be registered using visual analogue scales during 7 hours after the test meal and a total of 10 blood samples will be drawn to evaluate TAG in chylomicrons, plasma LDL, HDL and total cholesterol, plasma TAG, insulin, glucose and appetite hormone levels. At the end of the test day an ad libitum meal will be served and food intake registered.
