What should my glucose level be? Glucose Chart

Blood glucose levels give you an indication of whether your blood sugar is too low, too high, or just right. Tracking these levels is important if you’re managing diabetes or simply striving for optimal health because maintaining healthy levels helps reduce your risk of many common, life-threatening diseases, including diabetes, heart disease, stroke, cancer, Alzheimer’s, and Parkinson’s.

On the ketogenic diet and in general, glucose testing is a good way to identify foods that significantly trigger blood-sugar spikes in your body. Blood sugar responds quickly to food, and peaks about an hour after a meal. Generally speaking, you don’t want your blood sugar to spike more than 30 mg/dL from your baseline, and ideally your blood sugar should return to baseline within 2 hours; if it doesn’t, you may be having an insulin response to that food and may want to consider reducing or eliminating it from your diet.  With this knowledge, you can direct your diet away from foods that adversely affect your glucose levels and more toward foods that work best with your body.
