How Healthy Is Your Gut? Channel 4

With gut problems costing British businesses around £3 billion a year, and constipation alone losing the NHS over £150 million, it’s time to take action.

Sabrina Grant presents this one-off documentary, which explores why the gut is so important to our overall well-being and how it affects everything from our mood and energy to our sleep and health.

Assisted by six volunteers, all with a typical stomach complaint and all on a quest for a healthier gut, Sabrina puts some of the most popular regimes to the test and sees whether they actually work. If you have gut issues, this is one for you.
