How Do We Get Enough Iodine Without Eating Contaminated Seaweed?

Do we need to worry about getting enough iodine? Apparently, the recommended daily requirement for iodine is 150 mcg for both adult men and women. Where does one get it? Seaweed is supposed to be the best source for iodine. Also, iodized salt is up there at the top. But, iodized sea salt is a better choice than regular table salt.

‘Recently, concern has been raised about possible heavy metals contamination in seaweeds [1]’.

Iodine is plentiful in many animal products like dairy, fish and eggs, but I don’t feel the health risks involved in eating these are worth taking the chance. Lesser amounts are found in fruits and vegetables. For example, it’s in apples, bananas, peas and corn.

I don’t remember where I read it, but two medium russet potatoes each day would supply 120 mcg of iodine. I usually eat about two of them. Also, oats, soybeans and lentils are good sources. So, why not eat a little sprouted tofu? Beans also have it. Perfect breakfast: Fried potatoes, tofu and beans.

‘Seaweeds may have an important role in modulating chronic disease [2]’.

If you do eat seaweed for its iodine, be mindful where you get it. Apparently, North Atlantic seaweed is safe to eat. Countries like Iceland, Ireland, England, Scotland, France, Norway and along the North American and Canadian Atlantic coasts have traditionally been eating Dulse.

‘In November 2004, FSANZ issued a media release advising Australian consumers to avoid hijiki seaweed as it may contain high levels of naturally occurring inorganic arsenic [3]’.

The species of seaweed to scrutinize closely are Sargassum muticum and Sargassum fusiforme both of which are well known having high amounts of inorganic arsenic. Know your seaweed if you snack a lot on it.

‘If you eat a plant based whole food diet, and eat enough of the right fruits and vegetables in all the right amounts, and salt your food with an iodized salt, I would guess one wouldn’t have a problem getting either too much or not enough iodine. If in doubt, consult your family physician’ ~ your author

So far, it seems my theory is working out fine for me eating the way I do. I make sure I eat occasional organic seaweed snacks from Sprouts® market, though I have no idea where one would buy ‘safe to eat’ Icelandic sea kelp. It may be easier to find in capsules unless of course you plan on moving to Norway?

*Point of interest: You might want to read this article from Oregon state university. Wow! They’ve created a new strain of dulse that tastes like bacon!
