Hi Friend ,
Flax seed is an excellent source of soluble fiber, the fiber that helps reduce cholesterol. The AHA recommends 25-30 grams of fiber daily. 2/3 cup of flax seed contains around 28 grams of fiber. It also has lots of other really good components such as vitamins, minerals and unsaturated fatty acids.

There are lots of other good high soluble fiber sources, beans being a good example. Achieve Ultra Health
