Factual summary
Who is Dr. Diaa Al-Awadi and what is the Tayyibat system
Dr. Diaa Al-Awadi is an Egyptian medical doctor and the founder of the Tayyibat dietary system, a nutritional framework that combines clinical practice with a synthesis of traditional food categories. Trained in conventional medicine in Egypt, he developed Tayyibat as an educational method centred on three pillars: a two-hour digestion rule that spaces meals, a binary classification of foods into tayyibat, the good and beneficial, and khabaith, the heavy or harmful, and a focus on hormonal cycles before and after meals. The system identifies four hormones active during digestion, namely insulin, gastrin, histamine and serotonin, and four hormones that pause during the same period, glucagon, growth hormone, testosterone and cortisol. The teaching is delivered primarily in Arabic, through video lectures, and addresses the broader adult Arabic-speaking audience interested in dietary education and natural eating practices rooted in regional culinary tradition.
