Linseed is an excellent source of dietary fibre, alpha-linolenic acid and l
ignans. The quantity of seeds required to remedy obstipation is greater tha
n that required for adequate alpha-linolenic acid and lignan supply. Slight
ly crushed seeds are superior to whole or rough-ground seeds as far as the
laxative effect due to nearly intact seed structure and the release of at l
east parts of the desirable components are concerned.
