Quote:
"Mice that were fed by protein from GM soy demonstrated different behaviour. Some of the females in the GM soy group suffocated their young and then ate their brains. And it is also very sad that we identified abnormalities in the young mice whose mothers were fed on GM soy," said Maria Konovalova.


I think I'll stick with the oats
