Interventions/Control_1
At the first test session, participants consume the same standardized commercially available meal, and at the second test session, they consume hydrogen-rich jelly (10 g containing 0.3 mg of hydrogen). Exhaled hydrogen concentration is measured over time after each intake. A 1-week washout period is provided between the two test sessions.
