AFG2A and atrial fibrillation: Results in this study, however, reveal a clear indication of an uncommon AF occurrence pattern with higher amounts of the less potent AFB2 and AFG2 dihydro-derivatives and lower incidences of AFB1 and AFG1. Similar findings with high AFG2 content and trace amounts of other aflatoxins have been reported in nut and dried fruit samples [13], animal feeds [14], cereal samples [15], raw maize and groundnut samples [16], and palm kernel cake [17].
