Sugar reduction in complex food systems: linking metabolic mechanisms, matrix engineering, and safety evaluation

Summary

This narrative review examines the distinct metabolic effects of glucose and fructose beyond simple caloric content, and how food matrix structure and processing critically modulate sugar bioavailability and downstream metabolic responses. The authors synthesise contemporary technological approaches to sugar reduction—spanning sweetener chemistry, structural engineering, and digital formulation—and propose an integrated framework linking molecular metabolism, food engineering, and safety evaluation for rational design of reduced-sugar foods.

Regional applicability

The findings are methodologically generic and apply broadly to United Kingdom food product development and reformulation practice. However, the review does not present jurisdiction-specific regulatory or safety-assessment frameworks; application to UK law would require cross-reference to FSA and EFSA guidance on food additives and reformulation claims.

Key measures

Glycemic dynamics, de novo lipogenesis, insulin signaling, microbiota–host interactions, sugar bioavailability, ingredient stability, and safety assessment profiles

Outcomes reported

This review synthesises evidence on how glucose and fructose metabolism differ and how food matrix structure influences sugar bioavailability and metabolic outcomes. It evaluates technological approaches to sugar reduction—including non-sugar sweeteners, structural redesign, and digital formulation tools—with attention to safety profiles and regulatory frameworks.
