Porridge study: which corn meal keeps you full longer?
NCT ID NCT07204470
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how four different instant maize porridges affect hunger and fullness. Fifty healthy adults aged 18-35 with normal weight took part. They ate the porridges after fasting overnight and reported their appetite, plus gave blood samples to measure hunger-related hormones and blood sugar. The goal was to see if whole-grain maize porridge keeps people fuller longer than other types.
