Found the link to the cardiovascular statement in the link you posted... Got this from the site:
http://edocket.access.gpo.gov/cfr_20...1cfr101.71.htm
Sec. 101.71 Health claims: claims not authorized.
Health claims not authorized for foods in conventional food form or
for dietary supplements of vitamins, minerals, herbs, or other similar
substances:
(a) Dietary fiber and cardiovascular disease.
While I know you don't claim to cure/correct the disease "cardiovascular" is one of those words, you just stay away from. If I remember correctly, it's better to mix it with "exercise" (not a food) - Then you include cardiovascular health.
