Objective: According to European Commission Regulation No 432/2012, the incorporation into food of minerals and oligo-elements which are officially linked to a health claim means the “health claim” can be made for the food too. Nevertheless, their introduction into various food matrices can potentially influence their effectiveness. The objective of this study was to confirm the effect on daily mood, stress and sleep of a daily intake of magnesium- and B vitamin-enriched gingerbread for 3 weeks at the required quantities determined by EFSA (30% of RDAs).

Methods: Selection criteria: men or women, aged over 18 years and under 70 years of age, complaining of a mood or stress rated by an MSP-9 scale. Evaluation criteria: MSP-9, Brief Mood Introspection Scale (BMIS) and Spiegel scale for sleep. Daily data collection on a Smartphone CRF (NursTrial System) for 7 days before the consumption of gingerbread and during the last week of consumption.

Results: 185 persons aged 39 ± 12 years and mostly female were included in the study. The results show significant reductions in stress assessed by MSP-9, which significantly decreased from 42.6 ± 8.5 to 30.9 ± 8.4 (p<0.0001), a 26% improvement in BMIS-assessed mood from 38.6 ± 6.6 to 47.2 ± 7.3 (p<0.0001), an improvement of 25%, and quality of sleep evaluated by the Spiegel scale, which increased from 16.2 ± 3.5 to 19.3 ± 3.6 (p<0.0001), corresponding to an improvement of 23%. Some 35.1% of the subjects declared they were rather satisfied and 50.3% they were satisfied or very satisfied.
