During the May 5 episode of the ‘Howie Mandel Does Stuff’ podcast, Billy Bob Thornton shared the reason he follows a very restrictive diet.

The actor admitted that he avoids several food groups, including dairy, wheat, and meat. He explained that his blood type is AB-negative, which is considered to be one of the rarest blood types in the world, and said that it causes him stomach issues.

Currently, there are no studies demonstrating a link between diet and blood type, although some doctors suggest that those with the AB blood type usually have low stomach acid.

Indeed, the human body is a complex thing that we haven't quite totally figured out yet, and sometimes the reality of medical conditions can be stranger than fiction.

But these are the fruit of rare syndromes that make people behave in almost unbelievable ways.
