All fructose works the same in the body, whether it comes from corn syrup, cane sugar, beet sugar, strawberries, onions, or tomatoes.
I can't believe that anymore than saying all types of alcohols are the same. Care to drink Methanol, instead of ethanol? They are both alcohols, but drinking one of those forces the liver to create chemicals that destroy the optic nerve, and may even kill you. Look up the chemical structure, the minor differences are quite important.
It is the way the body metabolizes the ingested chemical structures that make all the difference. There are many types of sugars with different chemical structures within the broad generalization of "sugar". They are NOT all the same, or they wouldn't have different specific identifiers within the genre. (See the charts below.)
To assert that a human organ would treat all chemical structures with the same reactions seems extremely naive (or with intended subterfuge) to me.
It is parallel to asserting that anything with a Honda badge on it, has the exact same capabilities and functions, and are completely interchangeable in any applied role. However, Honda makes trucks, cars, motorcycles, ATVs, etc. that have individual capabilities that can't be interchanged in all applications, even though most will transport a human body over some distance and time span. Similarly, a Ford badge doesn't define much in the way of specific use or ability.
I dare say that if your cafe racer in the garage transformed into a Fat Boy, you wouldn't just say that all Motorcycles are the same and interchangeable.
Neither is "sugar".
If you intake a starch (carbohydrate) your body does NOT convert it to fructose, it converts it to glucose that all your cells can use directly, or it converts it to fat, which can later be converted to glucose during periods of scant caloric intake, should you ignore or suppress the Leptin hormone "signal" to the brain that tells you to stop intake.
I'm sorry you have diabetes, (my mother had it and didn't cope well). You might consider reading the book "NeanderThin" by Ray Audette (who was also a diabetic before engaging in a paleolithic diet). But, not everyone has the same genetic code, and our present society does not value a robust and resistant gene pool. My genes mandated poor eyesight (myopia at age 5 or 6). However, that does not mean there aren't factors that effect the species in a general way. Some may be acute (damage, debilitate, maim, debilitate in short period of time) or chronic (damage, debilitate, maim, debilitate over a longer period of time).
By the way, doctors can be mislead, too.
Cheers,
