Even with diabetes... Although this is not strictly a "diet" issue, for years, many doctors tried to strictly control blood sugar levels in their patients. Variations were frowned up. Turns out, research has now shown that such "overmanaged" patients actually fare worse than those who allow some flexibility in glucose levels. I have a quite knowledgeable family member who has diabetes, from whom I've learned this. As I've gotten older, I've watched a lot of... um, "best practices", in health care as in other matters, be debunked. And, in retrospect, the advice often was a matter of self-reinforcing opinion rather than demonstrated science and research results.
