[QUOTE="Shirley N., post: 1878856, member: 485798"] I watched today on YouTube a very interesting interview. The interviewee was Dr Joseph Kraft, a retired pathologist from Chicago who was the first, as part of a multi-disciplinary team, to devise a way of measuring blood insulin levels back in 1970. The interview took place in 2015 when he was a very clear thinking 93. He went on to devise the Kraft Test, a glucose tolerance test where insulin as well as blood glucose levels are measured following an oral dose of glucose. He claimed a result of this test which showed that an abnormally high and/or delayed insulin response meant that a person had diabetes long (about a decade) before the blood glucose response was abnormal. He went on to test thousands of patients over 20 years. He claimed he had never known of a patient who had coronary heart disease who was not already diabetic according to this test. He himself had found abnormalities in the hearts of patients who had died young which he thought might be due to the effects of high insulin levels, but he did not have the backing to investigate further. Other doctors also believed that high insulin caused damage to the inner ear causing balance problems and noises in the ear. Another doctor found damage to the kidneys on autopsy in younger "non-diabetic" patients similar to the damage in older diabetic patients. These doctors were largely disregarded and ridiculed at the time and did not pursue the matter presumably for the sake of their careers. Dr Kraft still believed that the vascular damage was caused by abnormally high [U]insulin[/U] levels, not high blood glucose, though that may be a factor later in the illness. This, as far as I can see, shines a very different light on treatment. Though insulin can be life-saving in an emergency, unless the doses can be regulated within the normal range, it may be the main cause of the very complications we seek to avoid. Dr Kraft would not commit himself on the benefits of various diets, he was a pathologist after all, but the risks of high blood insulin he indicated, would suggest that control of blood glucose by diet only, should be pursued wherever possible, to enable insulin doses to be reduced or discontinued. The link is YouTube "Kraft - Father of the Insulin Assay" Also interesting is his letter to Professor Grant in New Zealand available on [URL='https://profgrant.com/2013/08/16/josph-kraft-why-hyperinsulinemia-matters/']https://profgrant.com/2013/08/16/joseph-kraft-why-hyperinsulinemia-matters/[/URL] Dr Kraft died on 21st February 2017 aged 95.
