Possible
It would be hard to say honestly. I do notice differences in tastes can be caused by different things though. Any dairy products with high bacterial content can make the taste somewhat unpleasant. If the woman is around the time of her menstrual cycle it can have an iron like taste in it. I know one food that is common to change the taste is tomatoes. It is also common for tomatoes to cause odor down there as well. Just try and drink plenty of water and keep the toxins flushed out and you should be ok.
