Dr. Joseph Kraft, MD, MS, FCAP

Dr. Joseph R. Kraft, MD, MS, FCAP was a doctor specialized in pathology. He was Chairman of the Department of Clinical Pathology and Nuclear Medicine at St. Joseph Hospital, Chicago, Illinois for 35 years, and was appointed Chairman Emeritus upon retirement.

He wrote the book Diabetes Epidemic & You, which is based on his accumulated experience of 14,384 oral glucose tolerances and insulin assays (which are now known as “Kraft Tests”) which were done between 1972 to 1998 at the St. Joseph Hospital in Chicago, Illinois.

From Dr. Kraft’s studies, he discovered that despite high insulin levels (or hyperinsulinemia), glucose tolerance can be totally normal. Today, this still remains undiagnosed in clinical practice.  Hyperinsulinemia is essentially no different from early diabetes and denotes an increased risk for certain chronic diseases.

Dr. Joseph Kraft - Father of the Insulin Assay

Dr. Joseph R. Kraft developed and validated the ultimate (and earliest) test for diabetes back in the 1970's. His personal research and exceptional experience as a lifelong pathologist enabled him to link the vast majority of modern heart disease to undiagnosed diabetes. Kraft reached the age of 95 years in August 2015, just after myself and Dr. Jeffry Gerber conducted this interview. His legacy should be enormous - but it has gone unrecognised so far. Please share this free production as widely as possible in order to correct this rank injustice; you will also be helping the world to understand how Type 2 Diabetes can be PROPERLY diagnosed and resolved. With Kraft's early diagnosis, and the emerging realisation that diabetes can be prevented through specific dietary means, we can save millions from unnecessary cardiac death.

"Hyperinsulinemia and Dr. Joseph Kraft" - Catherine Crofts, PhD 

Let's hear it for Catherine who is near completing her PhD, which is based on the work of Dr. Joseph R. Kraft. Here she summarizes the phenomenal linkages between elevated Insulin and a dizzying range of chronic diseases. Here she explains some of how the modern medical world has disgracefully, shockingly underemphasized the crucial Insulin factor. For some reason they choose instead to prattle on about 'cholesterol' (a secondary, noisy factor, that needs to be discarded before damn near the whole world is diabetic). The ridiculous thing is that most 'cholesterol' issues...are driven by hyperinsulinemia in the first place. Please support her work by watching and commenting on this short video.

Postprandial insulin assay as the earliest biomarker for diagnosing pre-diabetes, type 2 diabetes and increased cardiovascular riskCurrently, approximately one in eleven US adults have diabetes, and more than one in three are pre-diabetic.1 Additionally, it is estimated that approximately two in five US adults will develop diabetes, with most of these cases being type 2 diabetes (T2D).2 According to data (2011–2012) recently published by Menke et al , 3 14.3% of US adults (over 20 years of age) were diabetic (9.1% were diagnosed as being diabetic, 5.2% having undiagnosed diabetes) and 38% were pre-diabetic, totalling 52.3% of US adults having pre-diabetes or diabetes.The burden of undiagnosed diabetes seems to have increased in parallel to the above estimates. Among people with diabetes, more than one-third went undiagnosed overall (36.4% (95% CI 30.5% to 42.7%)). Additionally, this burden was even higher among non-Hispanic Asian participants (50.9%; P = 0.004) and Hispanic participants (49.0%; P = 0.02).3 In view of this, it can be concluded that using fasting glucose, oral glucose tolerance test (OGTT) or A1c may not be the most effective early screening tool for T2D. Thus, incorporating fasting insulin and especially insulin assay after an OGTT as enhanced screening methods may help to increase the ability to detect diabetes and pre-diabetes, allowing earlier intervention to prevent diabetic complications. ### Kraft patterns Hyperinsulinaemia is thought to be aetiological in hypertension, obesity, atherosclerosis, microvascular disease, neurodegenerative disorders, idiopathic peripheral neuropathy and certain cancers,4 5 and is associated with idiopathic tinnitus, vertigo and hearing loss.6 A key research paper published in 1975 by Dr Joseph R Kraft comprised 3650 patients who were randomly referred for glucose tolerance testing.7 Dr Kraft described five different insulin patterns in response to a 100 g glucose load administered over 3–5 hours with insulin levels assessed at baseline, 30, 60, 120, and at minimum, 180 min. Further 240 and 300 min insulin levels were also considered in certain instances. Pattern I …
