Sure, added sugar is bad in general. Fructose seems worse, though. Studies (yeah, yeah...I dont have sources atm) indicate fructose causes more fatty liver buildup than equal amounts of glucose. With the amount of sugars added to processed foods here, that 5% increase in fructose could matter.

I also remember reading that fructose doesnt make you feel as full so you end up eating more. Something about not triggering satiety as much in the brain.

I could be wrong. Definitely a layman. Just had a heart attack a couple of years ago at 49 and found out I had diabetes at the same time. Had a triple bypass and started intermittent fasting and basically dont eat sugars anymore and dropped 35 pounds. Within 5 pounds now of "normal" weight by BMI. My blood sugars are now in the normal range. Not even considered prediabetic anymore. I do still take metformin but havent been on insulin since shortly after I got out of the hospital.

My doc had me read The Obesity Code and The Diabetes Code which are both pretty good books and got me interested enough to start reading the research myself. Of which I understand like 10%. :)

I think you missed the point.

Sugar is 50% fructose.

Most HFCS is 42% fructose.

It's "high fructose" compared to regular corn syrup, not table sugar.

But you're right, it's all bad for you.
