I have my glucose test on Friday. I have been told by people to lay off sugars and carbs this week a bit to prep for the test. For those of you who have taken the test before, what types of food do you recommend eating before the test? Fruits obviously have both carbs and sugars, as do most foods. Am I stuck with green veggies and salads with oil and vinegar? Any advice? I don't want to have to do the three hour test!
