Edit: I suppose my primary goal in all of this is longevity, and as such, I'd like to stack the deck in my favor to the greatest extent. I have mechanisms whereby the DNA damage from ionizing radiation produced by diagnostic x-rays can be repaired. Does this mean that I should be cavalier about x-rays and radiation in general simply because my body is robust enough to handle the occasional x-ray? No, I'd rather avoid them unless I break a bone or something so I have that much more chance of not developing cancer. This is the same motivation that leads me to cook meat at low temperatures. It's not going to kill me today or tomorrow if I don't, but who knows what that effect is over decades.
20g of fructose a day doesn't sound like a lot, but that 15g difference over 80 years is 438,000 grams of fructose. That's a lot of AGEs. I rather think that makes a difference.
Those saying "you'll have to pry the fructose from my cold, dead hands" may be creating something of a self-fulfilling prophecy.
