Iodine content of Sushi rice? 2017/7/10 04:13
I tried to find it out myself using google but could not find it, there was an interesting study about japanese iodine consumption but they did not mention iodine content from Sushi rice.
I also assume that all rice is cooked with Kombu not only Sushi rice?

Regular rice is only cooked in water...

Not everybody cooks sushi rice with a piece of kombu in the water - some do. I have seen other chefs cook their rice with a piece of charcoal (sumi) in the water. Still others don't put anything in the water. It's up to the chef.

Kenshiro,

What is your question?

You can obtain iodine through various foods other than kombu.

Kombu is used in most soup stock for Japanese cuisine, and plain rice is one of the rare dishes that does not require kombu.

Never seen Kombu added to rice, but maybe some places do so.

Iodine is an important prevention against goiter and is added (in some countries) to salt.

Thank you for the Reply. Well i get to eat a lot of Japanese Foods the next day and im always a litle paranoid about my health. Btw i did not know, i thought everyone would use Kombu for Sushi rice.

Well the point is i wanted to buy Kombu in a chinese store and it had a warning sign, it says that even a tiny amount like a square cm has dozens of times the recommended iodine content, at least i think it was something like that. On the Internet it says that the iodine gets quickly into the water and that Sushi Rice is cooked with Kombu.

Obviously the recommended doses is i think 300 micrograms a day or so and Japanese have according to a study 3000 a day on average. But somewere i else read that the organism of Japanese is used to it so they do not have these problems westerners might encounter.
Obviously for many westerners, even the most its ok anyway.

Here is what i found, there are better discriptions but i was trying to be quick
Too Much Iodine May Lead to Subclinical Hypothyroidism
Hypothyroidism occurs when your thyroid produces too little thyroid hormone, a condition that is often linked to iodine deficiency. Ironically, new research has shown that taking too much iodine may also lead to a subclinical version of the condition, which is a milder form that is often missed by laboratory tests. Along with sometimes exhibiting many of the same symptoms of hypothyroidism, such as fatigue and difficulty losing weight, people with subclinical hypothyroidism may have an increased risk of heart disease.
Some, however, may exhibit no symptoms at all.
The new study, published in the American Journal of Clinical Nutrition, revealed that study participants taking relatively higher doses of supplemental iodine -- 400 micrograms a day and more – paradoxically began developing subclinical hypothyroidism.

Oh, so you're suggesting that iodine is bad for your health.

Well, in Japan you are encouraged to obtain iodine. Or at least you're encouraged to eat seaweed because of its iodine as well as its many other minerals.

But a quick Japanese internet search does tell us that taking too much iodine is not good for your health. I wonder if this information is something relatively new to Japan, because I can't recall learning about it. A pediatrician even scolded me for not eating iodine-enhanced eggs while being pregnant, and that was nearly 30 years ago. But the internet also tells us that the Japanese generally react differently to iodine because of our long tradition of eating seaweed. By the way, the internet also tells us that iodine is something that all humans need to a certain extent.

Now, I'm not sure why you're focusing on kombu and also on sushi rice. Like I mentioned in my previous post, kombu is the basis of basic Japanese soup stock, so why just bother about sushi rice? Anyway, when making sushi rice, as well as many other Japanese flavored rice dishes, you use that kombu soup stock to cook the rice with (you don't actually cook it with the kombu, but just with the stock after taking the kombu out). Instant sushi rice mix usually contains kombu extract, so you can add it to plain rice that was cooked only with plain water.

The following Japanese website is just for reference on iodine:

So I don't know if any of this was of any help to you, but if you're worried about taking too much iodine through Japanese food, I encourage you to consult with doctors and health specialists from your own country. They will be able to tell you what is good or bad for your race and for people who have followed the same eating habits as you have. Hope it helps.

Thank you for your long reply and the time your took. Well it was because they said all iodine gets our of the kombu into the stock, but now that i think of it that does not sound really correct.

I also focused on Sushi because i really like Sushi so much, im not so interested in soups or noodles, only in Sushi and Unagi. Thats why i asked.

Anyhow i will at least feel better now when i eat Sushi in the next weeks. By the way yes the medical Information changes quite radically,for example in Germany they used to say that Sport is good if the muscle are sore and now they say its actually a bad sign.

I wouldnt be too worried about the iodine content, but sushi as a whole isnt a particularly healthy choice. It is probably more that it isnt so bad for you than that it is good for you.

Sushi rice has little or no fibre, and you'd be amazed if you saw the amount of salt that is thrown in when they cook it. Then if you have the omelette in it, that is cooked with sugar and mirin (sweet sake) and a small amount of soy so I dont think that it is all they great for you though the egg would have protein I suppose. Then the pickled ginger is dyed, the wasabi isnt really wasabi at all, it is horseradish with green dye, and the soy on the side is high in salt.

But compared to a big mac, it it the epitome of healthy eating.

There are many studies that warn the risks of eating sushi (just google it and you will see), yet according to the World Health Organization data of 2015, Japanese people live the longest. So much for the studies. Kombu or sushi may have nothing to do with it, and may be it's the soy beans or horse sashimi they eat.

Japanese people must be doing something better than all others. Who knows what? Stop analyzing and just enjoy.

Sushi is among the least common Japanese dishes in Japan. But on a related note, I would be most concerned with the preservatives they use for cheap packed sushi as opposed to authentic sushi.

Scientific evidence will be corrected later or cancel by other factors.
People with intense thoughts are typical targets for health products (fraud) that are not pharmaceutical products.

It is free to trust what you trust, but if you really want to know, you just study and become a scientist.

Iodine is essential for thyroid function but excess iodine is anti thyroid. The days in history when areas of countries were afflicted by goitre and cretinism because of low iodine are gone in the developed world. The days of marketing anxiety are probably increasing. Still.
