Being able to determine whether or not your blood glucose levels are healthy can help provide the useful and necessary information. This information can help you determine where adjustments need to be made in your diet, or what you are doing correctly.


What Are Healthy Blood Glucose Levels?

healthy blood glucose levelsIn general, normal fasting glucose levels are considered <100 mg/dl and <120 mg/dl for fed (2 hours after food consumption). According to most medical journals, the reference value for normal glucose levels is between 72-108 mg/dl. (1)

Fasting blood glucose levels between 100-125 mg/dL and fed levels between 140-199mg/dL are considered pre-diabetic. Fasting glucose levels >125 mg/dL and fed levels >200 mg/dL are considered diabetic. (1)

What Is An Oral Glucose Tolerance Test?

An oral glucose tolerance test is a simple method to determine how your body handles glucose, which in turn, gives insight into insulin production and sensitivity. An oral glucose tolerance test is constituted by an individual consuming a large bolus of glucose and then having their blood glucose levels tested periodically over the course of two hours to measure fluctuations.

Normal this type of test is done at a doctor’s office but can be done at home.
