Seaweed is a kind of snack that can be eaten when the bag is opened, and its nutritional value is also relatively high. Let's take a look at the nutritional value of seaweed:
1, enhancing immunity
Polysaccharides contained in seaweed can obviously enhance cellular immunity, promote lymphocyte transformation, improve organism immunity and significantly reduce the total content of cholesterol in serum.
2. Prevention of iron deficiency anemia
Seaweed is rich in mineral iron. The iron content of one piece of laver is almost equivalent to one piece of pork liver, and two pieces of laver are equivalent to three bottles of milk and one egg. Therefore, eating seaweed for women can prevent iron deficiency anemia. Relatively speaking, the nutritional value of seaweed is still quite high.
3, anti-cancer effect
Kelp is baked from laver and contains fat-soluble active chemical components, among which bromophenols and carotenoids have anti-cancer effects and are helpful to prevent and treat brain tumors, breast cancer, thyroid cancer and malignant lymphoma.
4. Conducive to children's growth and development.
Taurine in seaweed is not only beneficial to heart health, but also can promote the development of nervous system in infants, enhance children's memory, promote the development of retina and vision, and prevent gallstones.
Summary: The nutritional value of seaweed is still quite high. The above is only the special nutritional function of seaweed, and the benefits of eating more seaweed food are not introduced here.
The difference between seaweed and laver
Seaweed and laver are two similar but different foods. Porphyra yezoensis is one of many kinds of Porphyra yezoensis. Porphyra belongs to Cruciferae and usually grows on rocks near tides. There are still some differences between the two in processing, production and nutritional value. The specific differences between seaweed and laver are as follows:

Seaweed: It concentrates the minerals and various B vitamins in laver, especially riboflavin and nicotinic acid, as well as a large amount of carotene and vitamin E and a small amount of vitamin C..
3, the appearance is different

What are the disadvantages of eating too much seaweed?
Seaweed is a kind of food with high nutritional value, but its intake is limited in the usual eating process. If you eat too much seaweed, it is also harmful to your health. What are the disadvantages of eating too much seaweed? Let's talk about the harm of eating too much seaweed in detail:
1, thyroid cancer.
The iodine content in seaweed products is very rich. We should know that the high iodine content in the human body can stimulate the incidence of thyroid cancer. Iodine and estrogen contained in seaweed are two major causes of thyroid cancer, so seaweed should not be eaten too much, especially children should pay special attention.
2, leading to elevated blood pressure.
Seaweed foods also contain a lot of salt. For hypertensive patients, eating too much seaweed will lead to too much sodium in the diet, which will lead to the storage of water and sodium, increase the blood volume of hypertensive patients, and then increase blood pressure. Therefore, patients with hypertension should not eat more seaweed.
Summary: Although the nutritional value of seaweed food is relatively high, excessive consumption will still have an impact on people's health. The above two hazards are only one aspect. Bian Xiao would like to remind everyone to pay attention to reasonable consumption, especially children and the elderly.
