Datagrid result value

Question

Hi all,
I have a datagrid pulling data from SQL... Data looks like
ID          Michigan_Produce      Item
1           F                               Tea
2           T                               Apples
3           T                               Coffee
Now i have a data grid to show this uising flex front end.
The issue is where it says F or T i have to say False or True.
Is there a way to do that in datagrid itself or i have to write some function...
private   
{function produceResult(event:ResultEvent):void
if  
(event.result.length != 0){
produceResults = event.resultas ArrayCollection;
returnData.dataProvider = produceResults;
else
Alert.show(
"No records exists ");
<mx:DataGrid  
id="returnData" width="814" height="282" fontWeight="bold">
<mx:columns>
<mx:DataGridColumn headerText="ID" dataField="ID" width="75"/>
<mx:DataGridColumn headerText="Michigan Produced" dataField="Michigan_Produce" width="75"/>
<mx:DataGridColumn headerText="Item" dataField="Item"/>
</mx:columns> 
</mx:DataGrid>
Final product should look like:
ID          Michigan_Produce      Item
1           False                            Tea
2           True                             Apples
3           True                             Coffee
Any help is appreciated...
