3.2. Selenium levels
Se levels were significantly higher in fermented cow milks than in fermented goat milks (p < 0.05; Fig. 1). Among the fermented goat milks, no significant difference in Se level was found among our lab-produced yoghurt (n = 8), commercial yoghurts (n = 8), or commercial probiotic yoghurts (n = 4) ( Fig. 2). Among the fermented cow milks, no significant difference in Se was found between commercial yoghurts (n = 37) and commercial probiotic yoghurts (n = 18) (p > 0.05; Fig. 3).
