Cooking method matters: simple diet change shows promise for diabetes and heart health
NCT ID NCT07303842
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed trial tested a low-AGE diet in 36 adults aged 55-65 with type 2 diabetes, coronary artery disease, and overweight. Participants were instructed to boil or steam food instead of frying, grilling, or roasting. The diet reduced blood levels of a harmful compound called CML by 30%, which may help with insulin resistance and blood vessel health. While promising, the study was small and short-term, so more research is needed.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- low-advanced glycation end products (AGE) diet (boiling/steaming food, avoiding frying/grilling/roasting)
- What this could lead to
- If confirmed, this diet approach could help manage type 2 diabetes and reduce heart disease risk by lowering harmful compounds in the blood.
- What could go wrong
- This was a small, short-term study with only 36 participants. Long-term benefits and broader applicability are not yet proven.
