What Nidam al-Tayyibat says
The system rules out black tea, though it is ubiquitous in Egypt, citing the effect of its tannins on mineral absorption. Green tea is the intended alternative.
Sources differ: Le guide des cinq zones place cet aliment en zone jaune (autorise) ; les listes explicites recoupées le placent en zone rouge. Tier jaune/vert selon la source.
What conventional nutrition says
Conventional nutrition does not forbid black tea; its tannins can reduce iron absorption if it is drunk with meals, hence the advice to drink it away from meals.
