It's easy to understand. But plain boiled rice is fine and it was only from yesterday there's an article Here on which foods to avoid that may be of some use to you

ETA:- There are many conflicting stories on what to and what not to eat. Some people steer clear of everything that you're not "supposed" to eat and some people don't worry and just eat what they want. I steered clear of most things but I did cave and had some peanut butter towards the end. Basically use your best judgement, if you feel too guilty about having it then don't have it, people have eaten many things and their babies turned out alright. And way back when no one cared about what they ate and I sure ate a lot of things that are said to be no no's these days and they have had perfectly healthy children. Anyway, as I said use you best judgement, if it doesn't feel right don't do it.
