The unfortunate fact of many scientific studies is that they take a long time to disprove in the public consciousness.
As soon as a particularly intriguing or controversial study comes out, people hold onto it like gospel.
Case in point—if you have hypothyroidism, avoid the following:
kale, brussel sprouts, broccoli, flax seed, peanuts, strawberries, peaches or otherwise “goitrogenic” foods.
That’s a myth.
A study in the 50s “proved” that those foods are antithyroid.
Since then, the study has never been replicated, and has been attempted multiple times over the past 6 decades.
So if you have hypothyroidism, don’t avoid these vitamin-rich foods because of an old and disproven study.
