hi...my dad had 6 haert attacks and triple bypass.....28 years ago. At the time the dr. told him he was to use margarine exclusively,no butter.All the groups you name all endorsed this also....in your 3/11 post. How can you so confidently trust groups whose endorsement probably added to alot of peoples heart disease, they would've been better off eating the buttter.I personly don't know which diet is better but i definitely don't trust the heart ass.(no pun intended). just something to think about.
