I've always heard that women should follow their pregnancy cravings, especially when they are really sick. I think it's really interesting that I'm craving things that are amazingly high in folic acid... the latest is pickled beets. I ate a whole jar in less than 24 hours. And I've had an unbelievable desire to eat green peas. Add to the list asparagus, spinach salads, black beans, hummus, and a few others, and you have the list of foods high in folic acid from a web search I did. Funny.
