Hi, I see a couple of potential issues here.
First off, is it possible that you weigh more than you used to? Any extra body fat can make it more difficult for insulin to transport the glucose into your body's cells that it needs to use for energy, resulting in a higher level of glucose floating around in your blood. The body reacts to this situation by working the pancreas harder in order to pump out extra insulin to help with the job of transporting the glucose into the cells. The more weight you put on, the harder the pancreas has to work until it just poops out. My doctor has explained to me that this is how people get Type 2 diabetes.
As far as the kind of food that you are eating right now, I think that it would effect your blood sugar in an unfavorable way because it includes too many of the wrong type of carbs, such as flour based products (bread and pasta), and other highly processed foods such as the kashi bar, and sweets. If the rice you are eating is brown rice, then it would be preferable to any of the other grain-based items that you mentioned because it is a whole unprocessed food. All in all, I really feel that your diet relies much too heavily on starchy convenience foods. The best way to control blood sugar would be to eat a whole foods vegetable based diet, and to maintain your ideal weight.
BTW, how high was your blood sugar?
