Easy parsing using regexes and pattern matching.

gistfile1.scala

// The variable data could easily be an Iterator from scala.io.Source instance, it will work just the same.
val data = List("Food,Count","Cake,9","Biscuits,2","Cookie,10")
val Parser = """([^,]+),(\d+)""".r
val entries = data.collect{case Parser(food,count) => (food, count.toInt)}
