There is much misinformation about the effect of diet on cholesterol levels. The fact is: a diet high in fiber and low in fat, plus exercise, will dramatically lower cholesterol. The only factor is how much you really want to lower it, and how much broccoli you can tolerate in your smoothie.
I recommend controlling cholesterol by natural means. See http://naturalloweringcholesterol.blogspot.com/
Best of all, it is that they don’t try to sell you anything, the site is merely informative.
