Seaweed, for long and health life

It  is called “Seaweed” in English, it kind of classified as “sea junk”. The name itself gives the marine plant a negative connotation. Wonder if this is the cause of not able to see it on the supermarket in Australia.

But, If you have ever been in a seaside City Dalian, China, you’ll see the fresh seaweed exactly the same way as all other vegetable and seafood on the supermarket. Ordinary people consume seaweeds kind of like people here eat onions, celery and carrots. In Chinese, it called “海菜“, means   “sea vegetable”,  the keyword  is “菜” means vegetable, “海菜” tells that is a type of vegetable that from the sea.

Chinese would stew it with tofu or making “Chinese salads”, Japanese people use it to make sushi…

Seaweed has actually been called “the next superfood” by some. But what can this plant actually offer?

You are probably most familiar with the green, black or brown plants that wash up on the beach. According to the National Oceanic and Atmospheric Association, According to the USDA, raw kelp is a good source of calcium (healthy bones), magnesium (important for overall bodily health) and sodium (helps muscles and nerves work properly). Raw kelp is also a good source of vitamin A, important for eyesight and overall eye health, and vitamin K. Vitamin K plays a key role in helping blood coagulation, which is especially important to control bleeding. Aside from basic nutrition benefits, eating seaweed may have a number of other benefits you may not be aware of.


A comprehensive review showed that consuming seaweed can help with diabetes management. It’s low in calories, rich in fibber, and full of micro nutrients…


According to a 2014 study published in the journal Nutrients, nori, seaweed often used in sushi, is the most suitable plant-based source of vitamin B12. Vitamin B12 is critical for cellular metabolism, brain and nervous systems, and blood formation. Nori also contains high levels of other nutrients that vegetarian diets might be missing, such as iron and some types of polyunsaturated fatty acids. Most sources of Vitamin B12 are animal-derived foods, so for vegetarians, seaweed could be a big boost for getting important nutrients.


According to the American Thyroid Association, nearly 40 percent of the world’s population is at risk for iodine deficiency. That can lead to major health problems like goiter, hypothyroidism, and even mental disabilities in children whose mothers didn’t consume enough iodine during pregnancy. The body does not produce iodine on its own, so it is essential to include iodine in your diet.

A recent study found that a variety of seaweed can be a great source of iodine for women. According to the Institute of Medicine (IOM) Recommended Dietary Allowances for iodine, adults over 18 should aim to consume 150 µg (micrograms) of iodine each day. Seaweed iodine content can range from 16 to 3,000 µg per serving, so make sure to check iodine levels. (The IOM has also established a tolerable upper intake level of iodine of 1,100 µg.)

While seaweed is shown to have health benefits, but still haven’t seen fresh seaweed on the supermarket in Australia yet.
