Can somebody at Virta help us find the actual presentation at the 2017 world polyphenol conference on lectins and polyphenols and artery flexibility? I can only find the agenda where the title of the presentation and time is made. He described what he was going to say in an interview a few weeks earlier, more rigidity of arteries with re-introduction of lectins, but I cannot find the actual presentation. He had a publication in 2013 on the reversal of endothelial dysfunction, is why I think we should take this other publication seriously:
In the twentieth century, insulin was available only in an injectable form that required carrying syringes, needles, vials of insulin, and alcohol swabs. Clearly, patients found it difficult to take multiple shots each day; as a result, good blood sugar control was often difficult. Many pharmaceutical companies now offer discreet and convenient methods for delivering insulin.
Clearly separate from the characteristic lack of acute insulin secretion in response to increase in glucose supply is the matter of total mass of β-cells. The former determines the immediate metabolic response to eating, whereas the latter places a long-term limitation on total possible insulin response. Histological studies of the pancreas in type 2 diabetes consistently show an ∼50% reduction in number of β-cells compared with normal subjects (66). β-Cell loss appears to increase as duration of diabetes increases (67). The process is likely to be regulated by apoptosis, a mechanism known to be increased by chronic exposure to increased fatty acid metabolites (68). Ceramides, which are synthesized directly from fatty acids, are likely mediators of the lipid effects on apoptosis (10,69). In light of new knowledge about β-cell apoptosis and rates of turnover during adult life, it is conceivable that removal of adverse factors could result in restoration of normal β-cell number, even late in the disease (66,70). Plasticity of lineage and transdifferentiation of human adult β-cells could also be relevant, and the evidence for this has recently been reviewed (71). β-Cell number following reversal of type 2 diabetes remains to be examined, but overall, it is clear that at least a critical mass of β-cells is not permanently damaged but merely metabolically inhibited.
Since type 2 diabetes is merely excessive glucose in the body, burning it off will reverse the disease. While it may sound severe, fasting has been practiced for at least 2000 years. It is the oldest dietary therapy known. Literally millions of people throughout human history have fasted without problems. If you are taking prescription medications, you should seek the advice of a physician. But the bottom line comes to this.
Lunch. Salads are always a good option for lunch – load it up with meat or tofu, cheese, avocado, veggies and a full-fat dressing like olive oil or ranch. In a rush? Grab a lettuce-wrapped burger or bread-less sandwich from any fast food outlet. Like to cook? Try steak and brussels sprouts smothered in butter, salmon and asparagus with hollandaise sauce or a Thai curry made with tofu, coconut milk and green beans.
Hyperglycemic hyperosmolar nonketotic syndrome (HHNS). Signs and symptoms of this life-threatening condition include a blood sugar reading higher than 600 mg/dL (33.3 mmol/L), dry mouth, extreme thirst, fever greater than 101 F (38 C), drowsiness, confusion, vision loss, hallucinations and dark urine. Your blood sugar monitor may not be able to give you an exact reading at such high levels and may instead just read "high."
When islet cells have been transplanted via the Edmonton protocol, insulin production (and glycemic control) was restored, but at the expense of continued immunosuppression drugs. Encapsulation of the islet cells in a protective coating has been developed to block the immune response to transplanted cells, which relieves the burden of immunosuppression and benefits the longevity of the transplant.[72]

If you are interested in trying a natural treatment in addition to standard treatment, be sure do so only under the close supervision of your physician. If diabetes is not properly controlled, the consequences can be life-threatening. Also, inform your physician about any herbs, supplements, or natural treatments you are using, because some may interact with the medications you are taking and result in hypoglycemia unless properly coordinated. 
Late in the 19th century, sugar in the urine (glycosuria) was associated with diabetes. Various doctors studied the connection. Frederick Madison Allen studied diabetes in 1909–12, then published a large volume, Studies Concerning Glycosuria and Diabetes, (Boston, 1913). He invented a fasting treatment for diabetes called the Allen treatment for diabetes. His diet was an early attempt at managing diabetes.
These are a relatively new class of drugs used to treat type 2 diabetes. They are oral medications that work by blocking the kidneys' reabsorption of glucose, leading to increased glucose excretion and reduction of blood sugar levels. The US FDA approved the SGLT2 inhibitors canagliflozin (Invokana) in March 2013 and dapagliflozin (Farxiga) in January 2014.
