Diet and diabetes.

BACKGROUND: Guidelines for the prevention and management of type 2 diabetes mellitus (T2DM) reinforce lifestyle management, yet advice to guide general practitioners on principles around dietary choices is needed. OBJECTIVE: This article provides current evidence regarding the differing diets in diabetes prevention and management once T2DM arises, including the role in management of complications such as hypoglycaemia. DISCUSSION: Diets should incorporate weight maintenance or loss, while complementing changes in physical activity to optimise the metabolic effects of dietary advice. Using a structured, team-care approach supports pragmatic and sustainable individualised plans, while incorporating current evidence-based dietary approaches.
