I think it's all about what you have in front of you.
If my choice is between a banana and a cookie, I'll eat the banana every time.
If my choice is between a banana and a vegetable, it's going to depend on the vegetable, the time of day, and how I'm feeling. I'm probably never going to feel guilty for eating a banana because overall, compared to many other food choices, it's a sound choice.
I agree, however, about eating fruit in the morning - I tend not to eat fruit after noon or 1:00 or so, unless on the rare occasion I'm having a fruity dessert at a restaurant, or a friend's house party, or something like that (again, if my choice is between a fruit cocktail for dessert and a piece of chocolate cake, bring on the fruit!). Mostly this is because fruit IS a fairly simple carb (simple sugar) and it doesn't sit so well after mornings for me. I had no idea about the glycemic index when I started eating this way, it just seemed to make sense for my stomach, haha.
I totally agree that there is some fine wisdom here about more refined choices for food - when and where and how - but making the basic choice to eat more nutritionally vs. less nutritionally at any time of the day is always the right choice for me
