How can I find out how different foods affect my blood glucose?

If you want to know how various foods affect your blood sugar -- and for how long -- you should consider taking the Continuous Glucose Monitoring test, which measures blood sugar every five minutes.

You wear a sensor for seven days and get a report showing what is happening to blood sugar as you go through your daily activities. The test will not only tell you about how foods affect you but also let you correlate your blood-sugar readings to other activities, such as exercise and stressful situations. Simply keep a log of what you are doing at various times.
Measure your blood glucose 1 to 2 hours after you eat particular foods. Do you find that your blood glucose rises faster with carrots than with sweet potatoes?

By figuring out how your body responds, you can make adjustments in your plan, so that your blood glucose will not rise too high, too quickly.
