So back it up then. I would love to see any good research. Remember, if it isn't scientifically sound, I will ignore it. What I mean by scientifically sound is a) hasn't already been proven bad (see: Ansel Keys) and b) follows the scientific method.
I do eat nuts. And I am not afraid of cholesterol. In fact, I welcome it. There is one very large and influential study that proved that the risk of very low cholesterol (below 160) was much higher risk of health problems than high cholesterol (above 200, but below 240). I cannot remember the name but will try to find it. Basically, your body needs cholesterol to survive. Below levels of 160, people tend to develop nervous system disorders and other disorders at a higher rate than people with cholesterol at 200 had heart attack. Significantly higher rate, actually.
I avoid lean meat unless I am just in the mood. I do eat fish, however. Lean meat has no correlation to heart attack risk.
