Sucrose is metabolized in a different pathway than fructose. Fructose is directly metabolized by the liver, which is why things like High Fructose Corn Syrup is devastating for your body. HFCS directly causes fatty liver disease because as the fructose is metabolized by the liver, that’s where the fat accumulated. Fatty liver disease causes things like cirrhosis of the liver which could cause cancer.
I used to drink 6 Cokes a day and my liver blood tests were so high (ALT and AST) that my GP was worried I had liver cancer. I got an ultrasound and I only had fatty liver disease but it was pretty severe. I was overweight but not obese as per BMI. That “scared me straight” and once I started to lose weight my ALT and AST responded instantly.
I have a CGM and when I have cheat days and have Cheetos and a Coke, my blood sugar levels still spike to almost 300 which is diabetic levels but drop back to normal pretty quickly. Food like Cheetos are very quickly turned into blood sugar unnaturally quickly which is why processed carbs are extremely terrible for you and a major cause of pre diabetes.
