There is the answer ....high-fructose corn syrup.
“..high-fructose corn syrup. “
That’s what my doc said did it to me. I’ve controlled it with my diet, which has always been pretty good. But,,,, I don’t like soda pop, so I’d buy and drink fruit juices by the half gallon, thinking, “Hey! It’s fruit juice! It’s gotta be good for me!” Unfortunately, I didn’t realize the High Frucktose Corn Syrup was bad ju ju. I cut that cr@p out, and with my Asian-style diet, I’m only slightly above high normal, and don’t have to take meds.
