In conclusion, research suggests a direct link between sugar and cancer. Preclinical studies and studies of people with MetS show that high-sucrose or high-fructose diets activate several mechanistic pathways, including inflammation, glucose, and lipid metabolic pathways, suggesting a causal link between excess sugar consumption and cancer development and progression that is independent of weight gain. Dietary guidelines and US policy need to reflect this new knowledge. Concerted action is needed to lower sugar intake in the US and other countries, better inform the public of the risks of excess sugar intake, and conduct more robust research in the field of added sugar and cancer.

I was curious if cancer feeds off sugar. I thought I heard that.

Cancer is almost always in need of glucose, if you want to starve cancer, do a keto diet! (There are keto cancers but they were only discovered in late 2010s, very rare, and after a person has had cancer preciously).
