Ashley Broadwater is working on a story for Parade.com exploring the claim that 'Bulgarian yogurt is the best yogurt for gut health.' She is seeking gastroenterologists and registered dietitians as sources. Questions include: What exactly is Bulgarian yogurt? Any favorite brands or places you purchase them? Please explain the way(s) in which Bulgarian yogurt is beneficial for gut health; what other health benefits does it offer; how much do you recommend consuming for gut benefits; and what are other surprising/random foods that benefit gut health? Provide your name, credentials, and link to your bio/about page. If mentioning a study or research, please include a link. Please check with her before preparing a response to ensure there is still room for a source. Deadline is Thursday, February 5, EOD (11:59 p.m.). Earlier submission is better, and answers generated by AI should not be used.
