Watercress

Watercress is a member of the Brassica family, and like all the brassicas it should be fed in moderation because it contains goitrogens which interfere with the thyroid if eaten in excess.   Always ensure that store-bought produce is washed thoroughly before feeding.  See also Watercress in the Aquatic category.

Please be aware that two or more goitrogenic plants should not be fed in conjunction with each other, and the sum total of goitrogenic foods should not exceed the guideline for a single plant of 'in moderation' (amber-green) or 'sparingly' (amber-red).  This will ensure that goitrogenic consumption stays within safe limits.
