Hello @cwhii, I would like to add my welcome along with @lisalucier and other members. I'm certainly not an expert and I do have my problems with sugar consumption but I have cut back a lot. I have small fiber neuropathy and it really makes neuropathy worse so I've cut way back and only occassional treat myself. I used to drink a lot of pop and then switched to diet pop until I found out that it really makes the body crave more sweets. I looked at the site you referenced and linked to it below.

Dr. Linus Pauling did some research on the dangers of sugar which I think is where most of the data comes from.

I do know one thing. It's getting to be that time of year when all the treats start showing up and I really have to be on my best behavior and keep my hands in my pockets ☺
