Endemic goiter in rural Africa is prevalent due to diets high in goitrogenic foods like millet and cassava, which inhibit iodine absorption, especially when combined with low iodine intake.

“i think many other problems if you don't believe me then just look at rural africa and then the basically how many people there have endemic goiter which are these huge thick necks they are forced to eat many foods there millet or cassava which include goitrogens and those foods inhibit the absorption of iodine if you're eating a low iodine diet like they may be because they are not eating as many animal foods they're eating mostly plant foods and you are especially including a plant food diet that has many goitrogens you are going to end up with hyper hypertrophy of the thyroid which is these this endemic goiter these really big thick necks”

“um you know endemic goiter in africa to people who include more cassava in their diet which is often iodine deficient because they're not eating a lot of animal foods and they have worse outcomes similarly they have they have hugely uh hypertrophy thyroid glands and massive hypothyroidism from inadequate iodine absorption of the level of the thyroid due to the eye it's in cassava”

“you have only to look at um you know endemic goiter in africa to people who include more cassava in their diet which is often iodine deficient because they're not eating a lot of animal foods and they have worse outcomes similarly they have they have hugely uh hypertrophy thyroid glands and massive hypothyroidism from inadequate iodine absorption of the level of the thyroid due to the eye it's in cassava”

“in developing regions of the world where people don't get enough iodine in their diet vegetables root vegetables like cassava or Yuka are consistently known to be associated with the development of endemic goiter”
