Billy Bob Thornton Reveals Rare Blood Type And Diet Constraints Shape His Snack Choices
Billy Bob Thornton disclosed on a Howie Mandel Does Stuff episode that he has AB-negative blood, a rare type, along with multiple allergies that force a highly restricted diet (no dairy, wheat, shellfish, or meat). He described breakfast with blueberries and gluten-free, dairy-free chips later, and shared a green-room snack of grapes dipped in Dijon mustard that has become a go-to treat. The 70-year-old actor also touched on past drastic weight changes for roles but said he no longer does extreme body transformations, all while promoting Landman with Sam Elliott.
