K… so i recently got into an “odd” food for me. When i was on a roadtrip, i bought some dried seaweed and decided to try it out. At first i was like “blech” and then i realized it actually cured that craving for sushi i used to have.
BUT… i have heard random rumors about seaweed messing up thyroid? or hormones? Can anyone validate this claim? Or know of any info?
FWIW i dont have hypo/hyperthyroid issues
Seaweed has iodine, so it should help you. I guess it’s theoretically possible to eat too much of it, but that’s probably not going to happen.
I just listened to a podcast recently about iodine and the person said never seaweed, reason given was seaweed is literally an absorber of all the toxins in the water, said it’s used to clean up oil spills and you can potentially make yourself more toxic by eating it…let me try to find it for you 
I don’t think there’s a video for this, but I am pretty sure it was this podcast (I went on a listening binge recently lol).
As far as I know, most seaweed is raised in vats. I suppose the guys can control the quality of the water, (if they want to).
I’ve been eating seaweed daily for about two years. I am a seabear at heart. I have it at breakfast. I eat dried Pyropia species. It gets its name from being a red seaweed, but when it’s dried it is a deep green.
Seaweeds are many and varied. There are high iodine content ones and others milder, greener and less iodine content. They all have more concentrated ocean minerals and can make up, to some extent, for magnesium deficient soils resulting in magnesium depleted plant based foods and magnesium depleted animal based foods.
Sometimes I forage my own seaweed from the beach down the road. There are many edible species.
That thing about toxins sounds scary. It’s important to know, as it is for all our foods, the source and the environment in which it was produced. The local seafood is low in accumulated toxins.
Once again for any of these curiosity driven food experiments it all comes down to n=1. If iodine or thyroid is a concern, get a baseline test, eat the best seaweed you can get for the best price. After 30 days test again. Keep everything else as steady as possible: other foods, sleep, fasting, work load, socialising etc.
really! harvesting your own!! Do you dry it out or how do you prepare it?
If you eat to much of it for extended periods of time and your body is not used to it, it could mess up your thyroid.
E.g. Coastal Asian and other coastal nationalities and populations can handle more iodine because they have been eating more seaweed and marine life like shrimp most of their lives.
It could be one of many factors as to why rural Asians are or were so thin is because of the type of starch they eat or higher iodine diets.
If your poor you eat shrimp, if your wealthy you eat steak, beef…lol
That translates into if your wealthy you will be fat and if your poor you will be thin.
