One of the most important lessons for me just came recently: a lot of the books on low glycemic eating will tell about planning a meal that’s low GI, & include sample menus that include other foods (proteins, fats), but seldom do they come right outright & explain: always have your carbs with proteins and/or fats. (Lean proteins & the good fats, of course.) The exception might be having an apple or orange as a midafternoon snack… but for the starchy carbs like breads, pastas, etc., never eat them unaccompanied.
Or that’s how it seems to me. I’ve been keeping my blood glucose a lot more consistent since learning to do this.
