Does marine pollution cause you enough attention?  Seaweed Marine pollution has increased the iodine content in seaweed and seaweed. Daily eating is potentially risky.

Does "marine pollution" cause you enough attention? The plastic waste produced by humans every day has overloaded the marine ecology and affected the health of a variety of marine organisms. It seems that laver, kelp and seaweed, which are often used in Japanese cuisine, have been the first to be affected. Seaweed was originally rich in iodine and is a treasure of human health, but now it may become a poison that harms the body due to marine pollution. Let's take a look today!

Seaweed & other kind of sea vegetables are full  nutrients and often considered a type of superfood. However the recent study shows that pollution has affected  health of seaweed and eating  in large quantity or on daily basis would casue harm to human health.

Japan is the country with the highest consumption of laver in the world. According to statistics, the Japanese can eat as much as 10 billion laver a year! Seaweed has high nutritional value and delicious taste, which can be called the "vegetable in the ocean".

Laver that everyone eats is red algae, which mainly grows on the bottom of the sea where only the blue spectrum can penetrate and the water depth exceeds 100 meters. Because laver contains red and blue pigment proteins (phycocyanin, phycoerythrin), its appearance will be purple.

The latest research jointly conducted by researchers from Australia, the United Kingdom and China shows that the chemical composition of seawater has changed due to marine pollution, which has an impact on many types of seafood. Take seaweed as an example, although it can be in acidic water. One of the few species that breeds, but with the increase in carbon dioxide emissions, sea water absorbs part of the carbon emissions and causes ocean acidification. The increase in the acidity of the sea and the increase in ocean temperature will increase the iodine content in the seaweed Increasingly, if humans eat foods containing seaweed in large amounts or daily, such as sushi, seaweed, and kelp products, serious health problems may occur.

Seaweed has extremely high nutritional content, including vitamins A, B, C, and E necessary for the human body, as well as minerals such as potassium, calcium, magnesium, phosphorus, zinc, and manganese. The content that of selenium and iodine is particularly high.

Seaweed is also rich in dietary fiber. It can also wrap fat and cholesterol, facilitate gastrointestinal motility, and excrete fat and cholesterol from the body.

Iodine is actually one of the essential trace elements for the human body. It can help the human body produce thyroid hormones. The World Health Organization pointed out that if the human body lacks iodine, it may cause brain damage, and iodine deficiency is the main cause of brain damage around the world. The daily intake of iodine for children should be between 90-120 micrograms, and for adults (including teenagers over 13 years old) it is 150 micrograms.

However, eating too much iodine can also cause health hazards. If you take too much iodine for a long time, it can cause thyroid problems and even cancer. Researchers also remind everyone that fish and shellfish that feed on seaweed may also contain too much iodine. Therefore, frequent fish and seafood may also consume too much iodine. You should pay more attention.
