4 Reasons You Should Eat Seaweed

Seaweed can add so much flavor and depth to dishes, plus it is a great source of iodine and other nutrients! Learn 4 reasons why you should eat seaweed here.

Eating seaweed was something I heard a lot of jokes about in high school. It was viewed as kind of the ultimate dorky health food that “no one” could ever like. That’s changed in recent days because people have finally realized how delicious and beautiful Asian food is, and many traditional Asian dishes contain seaweed. Our sushi obsession has helped changed our mind as well.

Besides being delicious, it turns out that seaweed is a wonderful healthy food to include in your diet! My doctor recommended that I eat seaweed three times a week for health reasons, and I have failed in meeting that goal. So one of my recent pushes for myself was to start making a lot more dishes (for the benefit of the whole family!) on a regular basis that use seaweed in a delicious way.

But I’m not the only one that may benefit from seaweed! Here are four reasons you may want to join me in eating more seaweed!

Seaweed is delicious

From a culinary perspective, what would sushi be without nori, or what would miso soup be without wakame? So many Asian dishes get part of their scrumptious flavor from seaweed. My husband is half Japanese-American, and he has introduced me to Asian cooking that goes far beyond Americanized “Chinese take out”. As I have slowly worked at learning how to use a variety of seaweeds in dishes, I’ve learned there are many ways to enjoy it. So reason number one? It makes your Asian food more authentic and taste great as well.

Dr. Price noted the traditional consumption of it

In his book, Nutrition and Physical Degeneration, Dr. Price noted that those consuming a traditional diet who lived far away from the sea often went to extra-ordinary lengths to get seaweed. It was considered a very important food for maintaining health. For those of us who try to take cues from a nutrient dense diet based on traditional foods, adding in seaweed makes a lot of sense for us. This is especially true because many of us don’t eat iodized salt, but prefer unrefined salts that only have very minute amounts of iodine (if any, depending on the salt).

Traditionally, seaweed based soups and foods were given to the ailing, the pregnant, and the nursing mother.

Seaweed is a source of iodine and other nutrients

The reason seaweed was recommended to me was because it is a great source of iodine, and my levels were a little on the low side. Iodine is a crucial nutrient for us to get, and there is a lot of interesting research on the possible health benefits of iodine. It is also a source of vitamin C, manganese, vitamin B2, vitamin A, copper, pantothenic acid, potassium, iron, zinc, vitamin B6, niacin, phosphorus, and vitamin B1, and it contains protein as well.

The Weston A Price Foundation has a fascinating article on iodine’s possible health benefits that you may find helpful. They begin with this, “Iodine is critical to human health. It forms the basis of thyroid hormones and plays many other roles in human biochemistry. While the thyroid gland contains the body’s highest concentration of iodine, the salivary glands, brain, cerebrospinal fluid, gastric mucosea, breasts, ovaries and a part of the eye also concentrate iodine. In the brain, iodine is found in the choroid plexus, the area on the ventricles of the brain where cerebrospinal fluid (CSF) is produced, and in the substantia nigra, an area associated with Parkinson’s disease.”

Current research on the benefits of seaweed is encouraging

Take a peek at some of the research out there showing promise for the benefits of including seaweed in your diet.

Sea vegetables and lower blood pressure: “A 2011 study published in the American Chemical Society’s Journal of Agricultural and Food Chemistry reviewed 100 studies on the health benefits of seaweed and reported that some of the proteins in seaweed could serve as better sources of bioactive peptides than those in milk products. These reduce blood pressure, and boost heart health.” Times 

Seaweed and breast cancer: There is a lot of research on this topic as scientists attempt to figure out why Japanese women have such lower rates of breast cancer. Could seaweed consumption be part of the reason they have lower rates? Here are just two of many studies on the topic:

Seaweed May Improve Heart Health: Not surprising if it helps lower blood pressure, seaweed may be a heart protective food.

And those are just a few of the many, many studies out there. There is a reason that many call seaweed a “superfood”! Because of my new push to include seaweed in our diet more consistently, expect to see some dishes including seaweed in them soon.

And if anyone has a favorite recipe using seaweed, I’d love to hear about it!

    Where do you source your seaweed from? I have been uncomfortable with seaweed since the Fukushima melt down, but I haven’t put much research into it. Do you have thoughts on this?

  2. Sandra says

    Ive never been brave enough to put some Nori in my cooking like the packet suggests, does anybody know what it would make my food taste like and will it dissolve or have black flexs in it ???

      Are you talking about the kelp flakes? Sometimes I haven’t had the greatest results with that. I’d prefer putting a strip of kombu in my cooking (such as when cooking a pot of beans or broth), and then that’s easy to take out. 🙂

    My kids absolute favourite meal and so easy to make is to cook some sushi rice and mix it with some tuna, tamari, mayo and nori strips.

    I highly recommend AtlanticHoldfast.com out of Maine. I order their seaweed in bulk because it is so delicious. They pack recipes in with your seaweed so you’ll be at the ready when your package arrives. I use mostly wakame (in soups and stews and such) and nori (so good dry roasted with butter) but they are all great products. Lots of info on their website as well.

      Hey Zosia,

      Thanks for the link! And I agree. There are some important considerations to keep in mind if you choose to supplement with iodine. That’s one of the big reasons my doctor preferred for me to start eating seaweed instead of taking a supplement. 🙂

    We love to do our version of bibimbap. Sushi rice with sunny side up egg, seaweed, kimchi, fish or whatever on top. Dress with tamari and hot sauce. My daughter loves to stir it all up!

    I use the organic seaweed snacks from costco. Does seaweed have mercury in it? You said it is ok to eat everyday.

  7. says

    Last week try this! 🙂 It was awesome. I am in agreement with you that seaweed is a source of iodine and other nutrients and I have read a journal last week that is why I tried it in my home. I am from India, here is so hot weather. KimiHarris, can I try it everyday in one meal?
