A study of hungry people in Missouri finds more than four out of ten people eligible for food stamps don’t get them. Some don’t know they can get them. Some don’t want to seek the help. And some, says Peter DeSimone of the Missouri Association for Social Welfare, have just been left behind by all the changes in welfare laws. The report says one in twelve Missourians does not know where or when they’ll get their next meal…or whether the meal will be nutritious. The state department of social services says it is studying ways to overcome those problems.
