I saw all the reports on those paid studies.
Back in the late 90s early 00s I read about a study done in the 70s where a research group that had decided to try and induce high cholesterol in patients. Study was supposed to go on for 6 months but they had to quit it early because it worked too well. They fed the participants processed grain and sugar based foods to do so. Actually, if I remember correctly, what they fed has turned into the current standard american diet. The study didn't go over well in the "health" community for what are now obvious reasons.
I try and limit my sugar intake since I'm teetering on the edge of diabetes. It's an issue for many on mom's side of the family. Unlike my brothers, I've done very well on it not advancing. I have normal blood sugars and great blood work if I'm allowed to follow what I know I can handle food wise. Lots of veggies covered with butter and some meat. Adding fat into the diet was the hard part as it takes a lot to get over the brainwashing about fat from when I was a kid. But with the right amount of fat, you don't eat as much. It's kind of built in stop.
I'd rather have my kombucha than most other things so most of what I get sugar wise comes from what's left in that after the fermenting, but I do like a bit of homemade jam in my yogurt.
If you stick to the serving sizes from 50 years ago on stuff like ice cream, it satisfies the craving and you don't get too much extra sugar. And always eat the good stuff. No point in skipping something if it makes you overeat something else.
