Hi Liz
Sorry to hear about your diagnosis, most T2 try initially to control by diet alone but it can be hard. You need to talk to you Dr or Diabetic nurse to see about getting a blood glucose monitor and test strips. As you are diet controlled you will have to pay for prescriptions but depending on your health trust they should prescribe the strips for you. Self blood testing is important for those who are trying to control diabetes, as testing after eating tells us what certain foods do to our blood sugar level. For example some people find that eating bread causes high blood sugar levels 2 hours after eating it whils't others find the opposite. Pasta causes high blood sugars in me but rice is tolerable.
Testing by measuring sugar in your pee is a lot less sensitive than blood testing as most 'dipsticks' will only register any sugar in your urine if your blood glucose is around 10 mmol/l. As diabetics we are encouraged to keep our blood sugar between 4-6 mmol/l before eating and no more than 10mmol/l 2 hours after eating.
As to what to eat, your Dr may refer you to a dietician but the official line is eat a balanced diet of meat, fruit and veggies. Try to limit foods with high sugars such as sweets, chocolate, cakes and biscuits and high fats such as cheese. You will be told to eat some starchy foods with each meal such as pasta, rice, bread or potatoes but to use the wholemeal versions or brown rice as they are less easily digested and release their carbohydrates more slowly than the refined versions.
Many people find that they have to limit the amount of carbohydrates they eat to keep their blood sugars in the correct range (carbohydrates which are found in foods like bread and pasta are complex sugars which, over time during digestion, are broken down by the body to produce glucose the most simple sugar there is and which is used by the body to produce energy).
The most important message here is you need to know which foods cause you blood sugars to rise and then avoid them or only eat small amounts. To way to do this is to eat, record what you eat and then test your blood glucose using a simple finger prick test 2 hours after you have eaten. If your blood sugars were high then try with other foods.
Hope this helps
