How Food Effects Blood Sugar

What you eat has a greater impact on your blood sugar than anything else you do.

Whether you have diabetes or not, most of the food you eat is turned into sugar in order to fuel your body. That sugar moves through your bloodstream, providing energy to all of your cells—from your brain to your muscles.

Without insulin to unlock those cells and let the blood sugar in, your systems don't get the nourishment they need, and excess sugar stays in the bloodstream.

Think about it—when you eat, you're putting fuel into your body. That's why after you eat your blood sugar is higher than before. And why many people need to use insulin near mealtimes—to get the blood sugar out of the bloodstream and into the cells where it can do its job.
