This study is being done to look at age differences in the way the investigators bodies break down a compound found in flax seed (secoisolariciresinol diglucoside or SDG). It is administered to research subjects in a product called BeneFlax, which a concentrated version of flax seed containing 38% SDG. It is known that as people age, their bodies undergo physical changes both on the outside and the inside. The aging process may change the way that the investigators bodies deal with compounds the investigators eat. As an important measure of safety, the investigators want to check for evidence whether there is a difference in break down of SDG between different age groups.

Peak plasma concentration (Cmax) of secoisolariciresinol, enterodiol and enterolactone.
Blood samples will be collected at baseline and then post-dosing: every three hours for the first 48 hours, once at 72 hours and once at 96 hours. The concentrations of secoisolariciresinol, enterodiol and enterolactone will be quantitated at each time point.
Time frame: 0, 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 72, 96 hours post-dose
Time to reach peak plasma concentration (tmax) of secoisolariciresinol, enterodiol and enterolactone.
Blood samples will be collected at baseline and then post-dosing: every three hours for the first 48 hours, once at 72 hours and once at 96 hours. The concentrations of secoisolariciresinol, enterodiol and enterolactone will be quantitated at each time point.
Time frame: 0, 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 72, 96 hours post-dose
Area under the plasma concentration versus time curve (AUC) of secoisolariciresinol, enterodiol and enterolactone.
Blood samples will be collected at baseline and then post-dosing: every three hours for the first 48 hours, once at 72 hours and once at 96 hours. The concentrations of secoisolariciresinol, enterodiol and enterolactone will be quantitated at each time point.
Time frame: 0, 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 72, 96 hours post-dose
Elimination rate constant (k) of secoisolariciresinol, enterodiol and enterolactone.
Blood samples will be collected at baseline and then post-dosing: every three hours for the first 48 hours, once at 72 hours and once at 96 hours. The concentrations of secoisolariciresinol, enterodiol and enterolactone will be quantitated at each time point.
Time frame: 0, 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 72, 96 hours post-dose
Terminal phase half-life of secoisolariciresinol, enterodiol and enterolactone.
Blood samples will be collected at baseline and then post-dosing: every three hours for the first 48 hours, once at 72 hours and once at 96 hours. The concentrations of secoisolariciresinol, enterodiol and enterolactone will be quantitated at each time point.
