Dr. Diaa Al-Awadi is a professor specializing in functional medicine and therapeutic nutrition, having spent decades studying the relationship between food, the digestive system, and overall body health.

He developed the "Tayyibat System" as a revolutionary scientific approach that treats root causes rather than symptoms, built on a core principle: A healthy colon = A healthy body.

His dietary system is based on eliminating foods that stress the colon and cause chronic bloating and gas, while relying on wholesome, easily-digestible foods that nourish and heal the body.

He has a YouTube channel and a wide presence on social media where he explains his theories to millions of health enthusiasts in the Arab world.
