Billy Bob Thornton reveals brutal struggles over rare health issues

Billy Bob Thornton has opened up about the strict diet he follows every day because of a string of health issues and food allergies that leave him with very limited choices at mealtimes.

The 70-year-old Landman actor admitted his eating habits are far from glamorous, revealing he cannot eat wheat, dairy, beef or pork and often struggles to find food he can actually enjoy. 

Speaking on the Howie Mandel Does Stuff podcast, Billy Bob explained that he has the rare AB-negative blood type, which he believes contributes to his stomach troubles.

He said he spent years assuming everyone felt terrible after eating because he had lived with allergies for most of his life.

“I just assumed everybody felt like s--- after they ate,” the Oscar-winning actor confessed, adding that he only later realised his reactions were not normal.

Podcast host Howie Mandel joked that Billy Bob had “listed the entire food pyramid” after hearing the long list of foods he cannot touch.

Despite the restrictions, the Bad Santa favourite still finds ways to treat himself. 

Before the interview he had only eaten blueberries and decaf coffee, but admitted he was excited to head home for gluten-free crisps and dairy-free cream cheese.

The legendary actor also revealed one of his latest unusual snack discoveries after struggling to find safe food backstage at a Landman event with co-star Sam Elliott.

Surrounded by trays of meats and crackers he could not eat, he grabbed a grape and dipped it into spicy Dijon mustard and surprisingly loved it.
