My problem is, how do I ensure I get enough iron in my diet without eating high carb or high GI foods?"
High carb and high GI foods are not good sources of iron in the diet, unless they have been supplemented artificially, such as in a breakfast cereal. If you are aiming for low carb, breakfast cereals are best avoided. The best sources of iron are red meat, egg yolks, dark green leafy vegetables, beans (not the orange ones in a sugary sauce!), lentils and chick peas. There are other sources, such as some dried fruit, but these are bad for sugar levels.
Carbohydrates and sugars do not provide vital nutrients. You can get all you need from meat, fish, cheese, eggs, cream, butter, olive oil, beans and pulses, vegetables and fruit. "Sugars" should be avoided wherever possible. The amount of carbohydrates you eat (bread, pasta, potatoes, rice, pastry and other flour products, cereals and sugary items) is up to you. You need to test to see what your body will tolerate. If you are getting good blood sugar readings on 120 to 200 grams, then that is right for you, if not, you need to re-consider what you are eating.
