| Hi, Evan.
I think it's great you're here to learn.
Recipe-wise, generally avoid "white" foods (exept cauliflower & mayo) - pasta, potatoes, rice, bread, flour, sugar.
Remember "low-fat" usually means "higher-carb" (in other words, the opposite of what you want...)
Also, "no sugar added" doesn't mean less carbs, in fact in many cases there's *more* carbs than a similar serving of the "real" stuff.
Sugar-free baked goods...still have flour, unfortunately.
Some good things to eat: Eggs, meat, cheese, nuts, some veggies (not the high-starch ones like corn - or potatoes if you consider that a veggie!) dark chocolate...
Look around here, you'll find lots of recipes. You'd be surprised what cauliflower is good for. LOL I've seen and tried recipes that use it to replace noodles, potatoes & pizza crust. (the pizza crust is my personal favorite!
If she's a private person, I wouldn't push it...but maybe ask her to tell you if you've cooked something that doesn't work for her, because all diabetics are different & some are more affected by some foods than others. If she's not receptive to that, *shrug* but at least you'll have some idea from what you learn around here.  |
