Abstract Spontaneous urinary visible chemiluminiscence has been measured in samples from a diet intervention study in humans. For a month, two groups, each of 21 male volunteers, received either a Mediterranean‐type diet or an occidental (high‐fat) diet. Urinary chemiluminescence levels (in 10 3 cpm) were 8.5 ± 3.1 and 6.0 ± 2.0 for the high‐fat and Mediterranean‐type diets, respectively. The differences obtained were statistically significant. These results reflect differences in the oxidative stress associate to both diets and support the proposal that spontaneous urinary chemiluminiscence constitutes a complementary index of systemic oxidative stress.
