My toddler is angry..

My almost 2 year ago is very grumpy for the last week or two.. she’s just complaining about everything!! & when she doesn’t get her way she’ll yell and scream. She’s also a lot pickier now with food when she wasn’t so much before.. is this normal for an almost 2 year old? How should I start handling her tantrums & they way she yells angrily??
