I was flipping through Dr. Eades' book "Protein Power" the other day, and he said that saturated fat and cholesterol, even in the form of red meat, eggs and dairy, can be bad for your lipid profile if you're not following a fairly strict low-carb diet... That, while insulin levels are high, it contributes to arterial plaque build-up.
So, is this to say that you can't halfa** the PB? That, really, cholesterol and saturated fat CAN be bad for you, given that they're accompanied with a moderate/high carb diet? I've got my father going half PB, (eats plenty of red meat, nuts, vegetables, some eggs and cheese,) but he still has his occasional bowl of cereal, crackers or pasta once a week. Don't want to be harming the old man here!
