Cruciferous vegetables like broccoli and kale contain compounds that block iodine absorption in the thyroid and heart. This matters most for people eating plant-based diets who may not get enough iodine elsewhere. Fruits don't have this problem.
Chapters
about some scientists saying we shouldn't eat too much broccoli, kale, or cabbage. Aren't these supposed to be good for you? What's going on here?
You know, it's a funny question because it's counterintuitive to what we hear. And I have a podcast called The Zero Hunger Guide, and this is the number one question people ask because so many people are looking at plant-based nutrition. Shockingly though, plant-based nutrition, things like kale, broccoli, these things, cabbage included, can be problematic for people primarily because they contain plant defenses that inhibit the absorption of iodine at the level of the thyroid and the heart in the bodies and hormones. These plant defense mechanisms, because the plants don't wanna see them. Fruits are different, but these are all this family of cabbage. And unfortunately, they can cause these problems with thyroid and heart issues.
