Slushie machines installed in middle and high schools in the Madison, WI, School District prompted parental protests recently, reports the Capital Times. The units vend 8-oz. frozen concoctions priced at a dollar. Parents protested what they considered a non-nutritious addition to the school menu but district FSD Frank Kelly notes that the machines use 100% juice with no added sugar. The units are part of an experimental addition to the a la carte offerings at two middle schools and three high schools.
