Flax seeds contain high levels of dietary fiber as well as lignans, an abundance of micronutrients and omega-3 fatty acids (table). Studies have shown that flax seeds may lower cholesterol levels, although with differing results in terms of gender. One study found results were better for women [ 11 ] whereas a later study found benefits only for men. [ 12 ] Initial studies suggest that flax seeds taken in the diet may benefit individuals with certain types of breast [ 13 ] [ 14 ] and prostate cancers. [ 15 ] A study done at Duke University suggests that flaxseed may stunt the growth of prostate tumors, [ 15 ] although a meta-analysis found the evidence on this point to be inconclusive. [ 16 ] Flax may also lessen the severity of diabetes by stabilizing blood-sugar levels. [ 17 ] There is some support for the use of flax seed as a laxative due to its dietary fiber content [ 6 ] though excessive consumption without liquid can result in intestinal blockage. [ 18 ] Consuming large amounts of flax seed may impair the effectiveness of certain oral medications, due to its fiber content, [ 18 ] and may have adverse effects due to its content of neurotoxic cyanogen glycosides and immunosuppressive cyclic nonapeptides.

One of the main components of flax is lignan, which has plant estrogen as well as Antioxidants (flax contains up to 800 times more lignans than other plant foods contain). [ 19 ]
