Normal fasting blood sugar levels in non-diabetic men and women range from 70 to 99 milligrams per deciliter. Two hours after eating, blood sugar levels in non-diabetics should be less than 140 milligrams, according to experts at Virginia Mason Medical Center
Blood sugar, known as glucose, is a type of sugar obtained from carbohydrate-containing foods; after eating, the pancreas releases insulin to prevent levels from getting too high. Blood sugar levels fluctuate throughout the day and are influenced by the amount of exercise a person gets and the type and portions of food consumed during snacks and meals, reports Virginia Mason Medical Center.
