Interestingly, Dr Karan Rajan has recommended a specific food item that's not only good for gut health but surprisingly is also quite tasty. "This is my legal argument to explain why croissants should be considered a gut health food," he began in an Instagram video. ‌Dr Rajan went on to explain that fermentation can also result in the production of organic acids, which can enhance the glycemic response. "We know that chronic stress is a disruptor of the gut-brain axis," added Dr Rajan. It's recommended by the NHS to eat a healthy, balanced diet as a way of maintaining good health.
