Hmm, can we just say “trust us”? Sorry we haven’t had time to footnote every fact we’ve stated, but if you email us (see our Contact Us page), we’ll find a reference for anything you wonder about. You can also find just about anything at these websites:
American Diabetes Association’s website diabetes.org
NIH’s MedlinePlus website on diabetes at https://www.nlm.nih.gov/medlineplus/diabetes.html
NIH’s Diabetes A-Z website DiabetesA-Z
