Hi Happy girl, Carbohydrates i.e.. bread, rice, pasta and potatoes to name the main but not only, are the problem, try to reduce or cut out these foods groups and you should see an improvement in your bg, salads are great but better when jazzed up a little with jalapeño peppers, gherkins, olives etc etc, all meat is good (assuming your not veggie) eggs are awesome, vegetables (the ones that grow above ground are much less starchy, starch is carb so needs to be avoided) if i were you i would have a look at the low carb diet forum on this site, theres lots of info and menus to help you out
