Design outcomes

Primary

Measure	Time frame
Gene expression changes will be comprehensively analyzed before and after 4-weeks intervention. Furthermore, Lactoferrin, s-IgA and polyamine in milk as immunological aspect, NK cell activity, blood cell profiling, cortisol, IGF-1, MHPG, salivary amylase, s-IgA and oxidation/reduction potential as psychological aspect will be measured.	—

Secondary

Measure	Time frame
Changes in emotion and health by 4-weeks intervention will be assessed by Profile of mood states, the Subjective Well-being inventory and clinical laboratory profiles (hepatic and renal function).	—
