About the expert

Focus: Diet quality and type 2 diabetes risk

Qi Sun is a researcher at Harvard who studies how diet affects long-term health. His work looks at how food quality shapes the risk of type 2 diabetes. He focuses on careful, long-term nutrition studies.

Why this matters

These researchers work from large, long-term population studies rather than short-term diet trials. They treat food quality — not just carb count — as the main driver of diabetes risk, and they read single findings cautiously because the data is observational.

Two low-carb diets can have opposite effects on diabetes risk

Not all low-carb diets protect against diabetes — the foods you pick may matter more than the carb count. Plant proteins, legumes, nuts, and whole grains are associated with a lower risk of type 2 diabetes in long-term population studies. Red meat, refined starch, and white potatoes may raise it.
