Table 2.

Subjective positive and negative stress just before and just after lunch during the study weeks measured on a scale in which 1 = low intensity and 5 = high intensity. Data from the subgroup of participants (n = 32). Different letters next to the means indicate statistically significant difference (p ≤ 0.1) between the study weeks.
