DEAR DOCTOR K: Here we go again. After years of hearing that diets rich in saturated fats increase the risk for heart disease, I hear a new study says that's not so. What gives?
DEAR READER: I don't blame you for being frustrated. So let me start with the bottom line: Take this new study with several grains of salt. (Incidentally, it still is true that too much salt is bad for your health, so just a few grains, please.) Back in the 1970s and 1980s, you heard a lot about how fat was bad for you.
