an important one is by b. a. houssay, who showed that a high saturated fat diet prevented diabetes in rats and a high pufa diet caused it.
"In 1947, B. A. Houssay found that a diet based on sugar as a source of energy was more protective against diabetes than a diet based on lard, while the most protective diet was based on coconut oil. Lard reflects the pigs' diet, and is usually extremely unsaturated, especially since it became standard to fatten them on soybeans and corn. Essentially, his study seems to show that unsaturated (pork) fat permits diabetes to develop, sugar is slightly protective, and coconut oil is very protective against the form of diabetes caused by a poison."
piorry and bud cured diabetics using large amounts of sugar in the 1800s.
"Budd described another patient, a young man who had become too weak to work and who was losing weight at an extreme rate. Budd's prescription included 8 ounces of white sugar and 4 ounces of honey every day, and again, instead of increasing the amount of glucose in the urine, the amount decreased quickly as the patient began eating almost as much sugar as was being lost initially, and then as the loss of sugar in the urine decreased, the patient gained weight and recovered his strength."
the hyperglycemia in diabetes is the liver overproducing glucose , not a build up of unused sugar. diabetics die quicker without sugar.
"Since the first doctor noticed, hundreds of years ago, that the urine of a diabetic patient tasted sweet, it has been common to call the condition the sugar disease, or sugar diabetes, and since nothing was known about physiological chemistry, it was commonly believed that eating too much sugar had to be the cause, since the ability of the body to convert the protein in tissues into sugar wasn’t discovered until 1848, by Claude Bernard (who realized that diabetics lost more sugar than they took in). Even though patients continued to pass sugar in their urine until they died, despite the elimination of sugar from their diet, medical policy required that they be restrained to keep them from eating sugar. That prescientific medical belief, that eating sugar causes diabetes, is still held by a very large number, probably the majority, of physicians."
insulin allows you to use the glucose but it also blocks the free fatty acids
“Diabetes is caused by excess FFA floating in the blood, which blocks sugar oxidation as per the Randle cycle. Niacinamide lowers excess lipolysis/FFA and thus allows the cell to oxidize sugar again. Insulin also lowers FFA and also stimulates the glucose oxidation. This is why it is a therapy for diabetes. Diabetics have high FFA and glucose in the blood but the former part is almost never mentioned by doctors unless somebody ends up in ketoacidosis (driven by excess FFA) and even then the narrative is somehow still shifted to blame the "evil" sugar, while hyperglycemia is just a sign of high FFA.”
