In doing a little more looking at gene reports, I've just realized that my FUT2 status (non-secretor) has a negative impact on gut flora.


http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3098274/

"The secretor status determined by the FUT2 gene was strongly associated with the bifidobacterial diversity and composition. The non-secretor individuals only had about half of the bifidobacterial diversity and richness present in the secretor individuals based on the PCR-DGGE analysis. In addition, the non-secretor individuals had significantly reduced bifidobacterial abundance in comparison with the secretor individuals as measured by qPCR. Moreover, the non-secretor individuals lacked, or were rarely colonised by, several bifidobacterial DGGE genotypes, which were related to species B. adolescentis, P. catenulatum/pseudocatenulatum and B. bifidum, and were common in the secretor individuals."

English explanation and some suggestions...
