DEAR DOCTOR K: My parents made us drink milk every day, and I've continued that as an adult. A friend just told me that adults don't need milk, and that it can even be bad for you. What's the truth?
DEAR READER: Like you, we always had milk when I was a kid. In fact, the coming of the milkman to deliver the milk at home (remember him?) was an important event each day. These days, I have milk on cereal, but I don't drink it by the glass. As with most things, there are both benefits and risks.
