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.
