So the people for whom adherence to a healthy diet as an urgent matter of health, and whose poor diet, suffused actual sugar and high-glycemic-index carbohydrates (which almost instantaneously break down into simple sugars that flood the bloodstream), has placed them in a condition of insulin resistance, are not yet chronically exposed to the high expense of
injectable insulin. Thus, they are perhaps not yet sufficiently motivated to permanently change their diet.
During the time period when their poor eating habits are gradually killing their own natural insulin production capability, by chronic overuse if you will, they are not yet dependent on an external source of injectable insulin. During this time, they cannot reasonably be expected to be sensitive to, or even concerned about, the unpredictable and seemingly chronically high cost of manufactured injectable insulin. That’s a lot of soon to be users of injectable insulin who are not worried about the consequences of their actions.
Thinking about your point, to the extent such people are barrelling toward eventual insulin dependance, eating themselves into it, if you will, we as a country would benefit, as well as they would benefit as individuals, if they were to change course
in terms of their eating habits, and thereby never became insulin dependent.
It’s just that, before their pancreas gives in from overuse, they are still functioning based on their own, natural, pancreas-created insulin, and are thus not dwelling on, are not personally concerned about, are not given toward complaining about, the “future” (to them personally) costs of external-source injectable insulin, to which they will, in short order (if they do not start eating a healthy diet), be directly or indirectly exposed as gravely ill endocrinology patients.
Not only are bad carbs often cheaper, they are also addictive. When people suddenly stop heavy intake of breads, cakes, and junk snack foods, they are prone to experience physical withdrawal symptoms. Crazy, huh?
