Hi Carl, as an insulin user, yes you can eat 'anything' in theory but it's not always that easy to manage higher carb foods or to match them with insulin, especially at the start when you are finding your feet. Because your glucose levels were still high, I think the advice for now was to eat lower carb snacks foods to stop your levels going higher in these early stages. Your insulin works in conjunction with what you eat so as you get more experienced you can make your own choices as to how to manage it and how many carbs you wish to eat, etc. An orange by the way (a large one) has around 30 plus carbs in it so it would have the same effect on your levels as a chocolate eclair or 2 or 3 biscuits. Many of us require insulin for any food we consume that is over 10 to 15 carbs but as I say, it's test, test, test and you will become more experienced on how YOUR body reacts specifically. x
