Is watercress allowed on the Tayyibat diet?
No
No, by his rules. He never ruled on this food directly. The verdict follows from his rules.
Why watercress is off the list
Inside your gut it turns into sharp, harsh compounds. It can also stop your thyroid taking in the iodine it needs. Cabbage and arugula are out for the same reason.
The detail
Glucosinolates convert to sharp isothiocyanates in the gut, and goitrogens interfere with the thyroid's uptake of iodine, which is why cabbage and arugula are out.
The rule behind the verdict
The cabbage family
Did the doctor say this himself?
