Table 3 Mean ± SD of body weight, blood pressure (BP), triglyceride, insulin and glucose concentrations before and after each dietary intervention period and fecal volume, % dry matter (DM), excretion of energy and fat during each dietary intervention period (n = 17 for Control and Flax bread; n = 16 for Flax drink).

From: Flaxseed dietary fibers lower cholesterol and increase fecal fat excretion, but magnitude of effect depend on food type
