A science-backed breakdown of allulose, xylitol, and other metabolic sweeteners — and how they shape glucose, insulin, oxidative stress, and the metabolic terrain that affects cancer growth.

Introduction: Why “Allulose and Cancer” Is Becoming a Key Question

Cancer cells rely heavily on glucose uptake and glycolysis, even when oxygen is available — the hallmark Warburg effect.[i] Because of this metabolic preference, sweeteners that raise glucose and insulin can create a terrain more favorable to cancer progression, while sweeteners that stabilize metabolic pathways may support better outcomes.

Among all sweeteners, allulose is emerging as one of the most metabolically unique, with early research suggesting potential relevance to cancer metabolism.
