“It’s important to keep your blood sugar levels in your target range as much as possible to help prevent or delay long-term, serious health problems, such as heart disease, vision loss, and kidney disease. Staying in your target range of blood glucose (Before a meal glucose in the blood should range the following: 80 to 130 mg/dL. Two hours after the start of a meal: Less than 180 mg/dL.).  Keeping the glucose in therapeutic range can also help improve your energy and mood.”
