I think that Pauling was starting to find a solution to the problem. The book, PRACTICING MEDICINE WITHOUT A LICENSE? THE STORY OF LINUS PAULING THERAPY FOR HEART DISEASE by Owen Fonorow goes into detail about Pauling’s life and his therapy.
Low carbohydrate diets are also an area to explore as far as preventative health.
Also check out the International Network of Cholesterol Skeptics for tons of information on alternative ideas about heart disease. These are Phd’s and M.D’s - mostly outside the US - who are thinking contrary to most common practice (at least in USA) about how to prevent/help heart disease. http://www.thincs.org/
