Since I quit eating sugar (where "quit" means I mostly don't except for occasional guilty binges), I go through phases where I have my favorites "healthier" food. Such as:
Olives, tomato juice, goat cheese, and home made bread (made with more wheat flour or corn flour than white, and honey)
Dried apricots and pecans. (Careful not to go overboard. Too many dried apricots generates the STINKIEST farts ever!)
tostidos and salsa (check the label)
grapenuts with raisins and milk. I feel guilty about this one because all those have a fairly high GI, but they aren't sugar, and I think if I can cut sugar out entirely then it will get easier to cut back on the high GI foods.
If I were to identify one food as a staple, I'd pick bananas. I don't like that it's my staple, because they are environmentally unfriendly, and they don't have the best GI. But they cut the sugar cravings very well at 10 am which is my weak moment with the coke machine just up at the top of the stairs...
