As of my last update in early 2023, Kaye Foster-Powell is an Australian dietitian and nutritionist best known for her work on the glycemic index (GI) and its applications in diet and nutrition. She has contributed significantly to this field, co-authoring several books and scientific articles on GI and its role in managing diabetes, weight control, and general health. One of her notable works includes "The New Glucose Revolution" series, which she co-authored with Dr. Jennie Brand-Miller and others. This series explains how low-GI diets can help people maintain healthy blood sugar levels and offers practical advice on how to incorporate low-GI foods into one's diet. Her work often aims at providing accessible, evidence-based nutritional information to the public and health professionals alike. However, for the most current details about her work and any recent publications or achievements, a specific search with the latest information is recommended.
