I don't really post here anymore, but this might help someone else so I've got to share this. I have type 2 diabetes and was diagnosed February 2009 with fasting blood glucose of 350 and an A1c of 11.5. I got my A1C down to 6.5 in 3 months with exercise and a low carb diet.
As of yesterday's report, my A1C is 5.3. I gave up the low carb diet and have been eating carbs with dinner for the last 3 months. I avoid bread, rice, candy, desserts, etc. I love corn nachos and tacos and Vietnamese Pho.
I'll tell you what has really, really made a difference - vitamin D3. I accidentally increased my D3 intake from 2000 IUs to 3000 IUs a day (multivitamin, calcium tabs and D3 cap). OMG! My fasting numbers are in the low 80s. I still have sugar spikes but not as high and my blood glucose levels are back to normal within 2 hours.
But that was just the beginning. A blood test showed my vitamin D level was low. That was odd because I was spending a minimum of 5 hours a week in the Georgia sun and I was taking 2000 IUs of vitamin D3 a day. I increased my D3 dosage to 4000 IUs a day, and went back to eating carbs with dinner. After 30 years of not being able to drink coffee or tea because of caffeine intolerance, I can drink caffeinated beverages again. I've also been mildly depressed for years and to be honest, I've gone through at least 2 nasty depressions. I never expected a change - I feel peaceful, content, even optimistic about the future.
My point is simple - get your vitamin D level checked. Ideally, your 25-OH-vitamin D3 should be between 40 ng/ml and 70 ng/ml. The maximum safe level appears to be 80 ng/ml. If you're on insulin, be careful, because increasing vitamin D can cause lows. Do the research before you supplement. If you do choose to supplement, use an oil cap of Vitamin D3 for best absorption. It takes months to improve blood levels to normal and the only way to tell whether vitamin D levels have improved is by blood test.
