The "Dietary Guidelines for Chinese Residents (2016)" advocates eating more fruits and vegetables.
It is best to have vegetables every day and fruits every day.
Eat 300-500 grams of vegetables and 200-400 grams of fruits every day
.
This is because fruits and vegetables are important sources of vitamins, minerals, dietary fiber and plant compounds, which play an important role in maintaining human health and reducing the risk of chronic diseases

.
When it comes to vegetables, we tend to think of vegetables from the land
.
In fact, there is also a large category of vegetables in the ocean - seaweed
.
The kelp, seaweed, wakame, and stone cauliflower that we usually eat belong to marine algae
.
Next, let's take a look at the nutrition of seaweed

Seaweed has a unique flavor and nutritional value
.
In Asia, seaweed has been eaten as a vegetable for a long time, and studies have shown that seaweed contains a variety of nutrients and healthy biomass, mainly including:

Carbohydrates
Carbohydrates
Seaweed contains a large amount of carbohydrates, such as seaweed polysaccharide, dietary fiber, etc.
, accounting for 20% to 70% of the dry weight, and is the main component of seaweed
.

.
Seaweed polysaccharides are mostly cellulose, glucan, alginic acid, fucoidan, D-glucuronic acid, agar, carrageenan, starch, etc.
; For corn, rice, sorghum,
etc.
Many viscous soluble polysaccharides, such as pectin and guar gum, are beneficial for lowering cholesterol and lowering blood sugar, and are beneficial to human health

.
In addition, seaweed polysaccharides have effects on human body's antithrombotic, anticoagulant, anticancer, antiviral, anti-inflammatory, antibacterial and other physiological effects, and also have strong antioxidant activity

Proteins and Amino Acids
Proteins and Amino Acids
The nitrogen-containing compound content of various seaweeds varies greatly with the species, growing season and sea area.
Except for some special species, the protein content in general seaweeds is low, about 8%
.
Except for some special species, the protein content in general seaweeds is low, about 8%
.
Some red algae such as seaweed and some green algae such as prolifera and bag reef membrane are very high in protein content, up to 40%
.
Although the protein content of seaweed is generally low, its amino acid pattern is basically the same as that of soybean protein.
It belongs to high-quality protein and is highly utilized by the body

.
Most of the algal proteins have the functions of lowering blood pressure, regulating blood lipid balance and promoting the immune system
.

Lipids and fatty acids Lipids and fatty acids only account for 1% to 5% of seaweed dry matter
.
Most of the lipids and fatty acids in seaweed are unsaturated fatty acids, which are an important source of high-quality polyunsaturated fatty acids, mainly essential fatty acids such as linolenic acid, hypolinolenic acid and eicosapentaenoic acid (EPA)

Minerals
Minerals
The mineral content of seaweed is extremely rich, and it enriches dozens of macroelements and trace elements in seawater
.
Various minerals and trace elements account for about 20% to 30% of the dry weight, of which iodine content accounts for 0.
4% to 0.
7%, calcium content accounts for about 1.
3% to 5.
0%, and phosphorus accounts for about 0.
08% to 0.

Vitamins
Vitamins
Seaweed contains a rich and complete range of vitamins, especially a good source of B vitamins, and is also a natural producer of carotenoids
.
.
Among them, red algae, seaweed and green algae are the most abundant in vitamins
.
Such as vitamin C, vitamin D, vitamin E, vitamin K, vitamin B1, vitamin B2, vitamin B12 and so on
.
Vitamin C can enhance the immune defense system, activate intestinal absorption of iron ions, and help capture free radicals; vitamin E can prevent thrombosis,
etc.

Biologically active substances
Biologically active substances
In addition to providing essential nutrients for the human body, seaweed is also rich in a variety of biologically active substances, such as polyphenols (the highest content in brown algae), terpenes, sterols, sulfur heterocycles and other substances
.
These bioactive substances have the functions of inhibiting tumor, anti-oxidation, protecting cardiovascular, and enhancing immunity, which can promote health
