5. Chelsea Clinton
Chelsea Clinton is known for being the daughter of former president Bill Clinton and former presidential candidate Hillary Clinton. She's also mom to Charlotte and Aidan. While most people know about the former president’s gluten-free diet (due to apparent health conditions), many people don’t know that Chelsea has inherited gluten issues. Chelsea Clinton is severely allergic to gluten. This is why she completely gave up gluten and adopted the diet.
