What are good and tolerable foods to eat that are lite while receiving chemotherapy treatments?

Hello to all, I need alittle help and suggestions on what my mother can eat while she is recieving her treatments. Something that is lite and tolerable. I am at a blank excpet for toast/crackers/jello. Any ideas will be helpful just to get her along with this so she doesnt become week during her 6 cycles of the treatment. Is there anybody out there that has wondered that same question ? Thank You, Tina ~
