Why you shouldn’t completely cut sugar out of your diet

Dr Courtney (Thompson) Stewart was featured in Body+Soul (The House of Wellness) providing expert commentary on sugar intake and why a complete sugar ban may not be the most effective approach to long-term health.

The article explored the distinction between naturally occurring sugars and added sugars, clarifying common misconceptions around glucose, fructose and glycaemic index (GI). Courtney explained that while excessive added sugar intake is linked to increased risk of chronic conditions such as type 2 diabetes and obesity, carbohydrates remain the body’s preferred energy source – essential for brain function, central nervous system activity, growth and repair.

The feature also addressed the potential consequences of eliminating sugar entirely, including low energy, irritability, headaches and impaired concentration. Courtney reinforced that nutrition should not be framed in extremes, and that sustainable dietary patterns are grounded in balance, variety and moderation.

Importantly, the article referenced national and international guidelines, including the National Health and Medical Research Council’s recommendation that carbohydrates provide 45–60% of total energy intake, and the World Health Organisation’s guidance to limit added sugars to less than 10% of total energy intake (approximately 50g per day). Practical advice focused on prioritising wholegrain breads, legumes, fruit, dairy and other nutrient-dense carbohydrate sources over refined discretionary options.

This feature highlights Courtney’s ability to provide nuanced, evidence-based commentary on complex and often polarising nutrition topics for a mainstream national audience.
