Natava, you are very wise to be concerned about your blood sugar. You're still young and with the knowledge we have today, you may be able to control diabetes with diet and exercise but it's up to you to take control of your health. Diabetes is on my mother's side, so for me it wasn't a surprise when I had elevated fasting numbers creeping up every year through my 50's. Thankfully my doctor prescribed a blood sugar monitor so I could see how high my blood sugar was after my meals. Yikes. When I cut out those carbs, I brought my blood sugar and my cholesterol down to normal levels, and I lost weight. As you have seen, there are diabetics who eat all the cake they want and take or inject lots of meds. This is not a good way to live. High blood sugar will damage your heart, kidneys, eyesight and nerves (causing neuropathy), to name a few conditions. Diabetes can shorten your life and lessen the quality of life if the blood sugar is not controlled.
You'll survive without bread and the potatoes, trust me! I have and I used to live on the stuff. But as I saw my blood sugar come down and my weight, that was worth giving up the carbs. So, please stick around!
