I found some other studies that show a damaging effect of having a high fructose diet. Disclaimer: I am not a scientist nor do I have a scientific background so I might be missing something entirely. From what I can tell though, eating small amounts of fruit is probably fine, I just wouldn't make it a major part of your diet. I have seen in myself and others people who juice fruits or eat them regularly as snacks and they usually have a hard time losing bodyfat and can't figure out why because they think that fruit is "so healthy." It's still sugar. There's fiber there, but your body still processes it as sugar.
Rat offspring fed high fructose diet are at risk of developing metabolic syndrome later in life.
In rats, HFr consumption for 6 wk caused dyslipidemia, insulin resistance, reduced plasma adiponectin, adiposity, and adipose tissue inflammation.
Adiponectin resistance and proinflammatory changes in the visceral adipose tissue induced by fructose consumption via ketohexokinase-dependent pathway.
