A Glimpse on Seaweeds

It has been known for a long time that seaweed contains many nutrients. These nutrients include iodine, iron, calcium, magnesium, potassium, zinc, copper, manganese, selenium, vitamin B12, vitamin C, and omega-3 fatty acids. These nutrients can be found in minerals or organic compounds such as proteins, carbohydrates, polyunsaturated fats, and vitamins. In addition to this, seaweeds contain antioxidants, which help prevent diseases like cancer, cardiovascular disease, and diabetes. In the past, people used seaweeds as food because it was easy to find and inexpensive. However, nowadays, there is an increasing interest in seaweeds due to their nutritional value.

Why do we need to eat seaweed?

Seaweed is full of nutrients that our bodies need. These nutrients include iodine, iron, calcium, magnesium, potassium, zinc. Our bodies cannot produce these nutrients independently, so we must get them through our diet.


Iodine is necessary for thyroid function. Many people have problems with their thyroid gland, especially when they are pregnant. Therefore, consuming seaweed can help maintain normal thyroid function.


Iron is needed by the body to make red blood cells. When we don’t get enough iron, our red blood cell count will drop. As a result, our blood becomes less oxygenated, and our muscles become weak. Eating seaweed can help keep us strong and energized.


Calcium is essential for bone growth and development. Without sufficient calcium, bones become brittle and break easily. However, too much calcium can cause kidney stones.


Magnesium is required for muscle contraction and nerve conduction. It also plays a role in maintaining the proper functioning of the heart.


Potassium is essential for regulating fluid balance within the body.


Zinc is an essential mineral that is involved in many bodily functions. It is needed for wound healing, immune system function, and metabolism.


Seaweed has been shown to protect against cancer and cardiovascular diseases. It is believed that seaweed helps prevent cancer by increasing antioxidant activity. Antioxidants are chemicals that protect the body from damage caused by free radicals. Free radicals are molecules that cause oxidative stress. Oxidative stress may lead to mutations in DNA, which can turn healthy cells into cancerous ones.
Seaweed is rich in antioxidants such as polyphenols and carotenoids. Polyphenols are compounds found in plants that act as antioxidants. Carotenoids are pigments produced by plants that give fruits and vegetables their color.
