Thiocyanates (SCNs) are a group of molecules formed as a result of glucosinolate hydrolysis. See: Glucosinolates.
Thiocyanates compete with iodine and can inhibit iodine uptake by the thyroid gland. SCNs improve outcomes of individuals with sickle-cell anemia. Sickle-cell anemia is more common in persons with African heritage. African staples of cassava and African yam are less common in the African-American diet, which may reduce intake of beneficial SCNs.
Hypothyroidal or iodine-deficient persons should take note of thiocyanates’ ability to interfere with iodine uptake.
African yam, cassava, millet, buckwheat, lima beans, cabbage, cauliflower, plantain, broccoli, chickpeas, sorghum
