Saying that food with a high glycemic index is simply “not good food” shows a lack of understanding regarding what the glycemic index indicates and what constitutes “good food”.
There’s food with a high glycemic index that is most certainly not “bad food” (like fruit), and there’s food with a low glycemic index that definitely could be by what I assume is your criteria (like butter).
Also the statement “cereals have a high glycemic index” isn’t even true, since some of them do (like corn flakes), while some of them don’t (oatmeal, which is close to oranges).
Fruit that I would consider as good food have a lower GI than your favorite cereal, so your argument that there exists high GI food that works well as good food, doesn’t stand. Bad example. There’s definitely fruit out there that I would only rarely touch.
