That’s what the body considers a benign amount of blood sugar. That’s about four or five grams’ worth of glucose in your blood or about twenty calories’ worth. You’ll be diagnosed as diabetic if your blood sugar levels while you’re fasting (i.e., in the morning, before breakfast) are even moderately above that level: maybe a teaspoon and a half of glucose, or the equivalent of about thirty total calories of glucose circulating throughout your entire body.
