Is this normal toddler behavior?

I have a 13 and a half month old who is suddenly spitting out all kinds of foods she used to eat. The weird thing is she will spit out a bite and then take another bite of the same thing. Sometimes she will swallow it and sometimes she won’t. Is there some sort of change in taste buds or mental brain function around this age? She used to love carrots & peas and now she hardly eats it. That’s just one example of many. Does anyone know how to get my adventurous eater back?
