It is important to mention the proneness or predisposition one has to any ailment. While I have all but eliminated any white flour, bread, rolls, soda, and most high (bad) carb foods, my dad defies this definitively. He has a strong heart and no artery, heart, or blood pressure issues at 83 years old, and his diet (much to my dismay and objection) includes white bread/rolls, soda, candy, cake, french fries, basically, a McDonalds' diet every day of his life.
Go figure...that diet would kill me, just thinking about it. :)
