But with this kind of research we get contradicting results every other year. First milk was important for you, now milk is harmful. Eggs used to be the way to an early grave, now eggs are the fountain of youth. Cholesterol was deadly, now we need it like a drug.
We don't, really. The foundation of a lot of the confusion was the U.S. government recommendations of 1977, which were often not based on any science. I suspect corruption, but incompetence might have been a factor. There were some voodoo notions about calcium, cholesterol, sodium and fiber. Even the Feds have since retracted the idea that dietary cholesterol is meaningful.
Milk is fine in reasonable amounts, if you can digest it; probably 1/3-1/2 of the recommendations. You don't need the skim crap. Eggs have always been fine. Sodium is fine up to at least three times the U.S. recommended maximum. You probably want only half of the recommended fiber intake. That's what my research suggests but, bodies differ, and experiment for yourself.
