ExploreA balanced scientific reading
The system's general idea — reducing processed foods and returning to natural food — overlaps with common nutritional guidance. On the other hand, some of its detailed claims about specific foods are not backed by strong scientific evidence and have prompted debate among specialists.
So we present the system as Dr. Diaa set it out, while reminding readers that the best approach is to treat it as a general dietary pattern, continue your usual medical follow-up, and never stop any prescribed medication or treatment. This site offers no therapeutic advice.
FAQ on evidence & safety
Is there scientific evidence supporting the Tayebat System?
Its general idea (reducing processed foods and returning to natural food) aligns with well-known nutritional guidance. But some of its details and claims about specific foods lack strong evidence and are debated, so it is best treated as a general dietary pattern, not a treatment.
Is the system safe for people with diabetes or high blood pressure?
Any major dietary change can affect people with diabetes or hypertension and their medication doses. Do not start the system or stop any medication without consulting your treating physician, who is best placed to assess your case.
Should I stop my medication if I start the system?
No, absolutely not. Nothing on this site calls for stopping any medication or treatment. Continue what your doctor prescribed; any change should be under their supervision alone.
Is the system suitable for pregnant women and children?
Groups such as pregnant and breastfeeding women and children need special nutritional care. Consult your doctor or a dietitian before following any system, to ensure the body gets all it needs.
