Martha Stewart has reportedly tried a gluten-free diet for three days, with some outlets suggesting the experiment had positive effects on her health. It is unclear what specific health benefits she experienced, but brain fog and bloating are mentioned as potential issues that may have been alleviated. The story appears to be related to celiac disease and gluten sensitivity, although some reports seem unrelated, discussing separate topics such as a cardiologist's smoothie recommendation and the effects of eating sourdough bread.
