Quote from FMPONE
Fructose is awful, so no, there is nothing great about "natural" sugars in fruit. It's just that historically, fructose levels were low. And yes, we have altered fruit, by selectively breeding fruits highest in fructose generation after generation. It's kind of like why all tomatoes you buy from a store nowadays tend to be so bland and flavorless, we've bred only the nice red shiny ones, which tend to be sort of bland and flavorless compared to "uglier" tomatoes. This is one of the reasons apples taste like candy nowadays, once upon a time you would take an apple off a tree and it would have fructose in it and therefore signal to your brain that this plant was most likely safe to eat, but it wasn't the arbitrarily high levels of fructose in modern apple crops. Modern fruit takes advantage of our brains' evolutionary reward system which is designed to respond to foods that are likely to keep us alive, fruits were historically some of the safest and least toxic food stuffs for early humans, but now we've fucked that all up by boosting sugars....But you're forgetting that we've done the same for animal products as well. Animals have since the 70s been fed food that would increase growth for slaughter. We're only now figuring out that maybe feeding them toxic stuff also rubs off on the end consumer (see: cancer). By contrast there was this one lady who only ate fruit and veggie for like 50 years and apparently she outlived everybody. I'm not one to judge whether or not there is something to it, but we definitely have to go out from the perspective that everything we eat and do is bad for us. Even the oxygen in the air we breathe slowly oxidates (i.e. sets on fire) our internal systems and skin - which also one of the main reasons for process of physical ageing.
Pick your poison - you might as well, you're not getting out of this alive.
