Sea kale (kelp) is a brown algae, characterized by a high content of macro- and microelements, in particular iodine. It is widely distributed in the northern seas. In the extraction and processing of algae, the laurels of the championship belong to Japan. Laminaria is used in nutrition (for the prevention of endemic goiter), medicine (for the production of laxatives), cosmetology (to improve skin condition) and in agriculture (as a fertilizer).
To fill the body’s daily need for iodine, it is enough to consume 40 g of fresh kelp per day. Interestingly, the doctors of ancient China called the seaweed sea ginseng because of its ability to improve well-being and quickly restore human strength. In addition, cabbage contains sterols (“fighters” with cholesterol), which prolong the youth of the body, prevent the development of atherosclerosis and improve blood counts. These compounds resist the formation of blood clots and normalize the menstrual cycle in the beautiful half of humanity.
Useful Properties
The greatest value for the human body is fresh or dried kelp, obtained in the cold northern waters. Interestingly, seaweed grows throughout life (11-18 years) in places with a constant current and can reach up to 20 m in length.
Eastern countries have long used this product in a variety of ways. Soups are cooked on its basis, sweets, marshmallows, sauces and salads are prepared. Seaweed is pickled, frozen, dried, fried and consumed fresh. It is a unique source of fiber, proteins, polysaccharides, phytosterols, vitamins A, B, C, PP, E, D, K, H, potassium, calcium, sulfur, phosphorus, magnesium, sodium, iron, iodine, boron, bromine.
Medicinal properties of seaweed:
- Neutralizes radionuclides, removes salts of heavy metals and toxins, reduces the risk of cancer. Laminaria owes these properties to biologically active substances – alginates. They are used in the food industry under the codes E400-E404, E406, E421 in the manufacture of ice cream, bread, creams, jelly, jam. Thus, “E” is not always preservatives, sometimes it is simply the components of sea kale that have a beneficial effect on the human body.
- Normalizes bowel function, has a mild laxative effect, is indicated for use in chronic constipation. In the stomach, kelp swells, which causes a reflex increase in intestinal motility.

Seaweed is a low-calorie product (10-25 kcal / 100 g), which, when ingested, dulls the feeling of hunger for 2-3 hours. As a result, weight loss is much easier. [1].
- Replenishes iodine deficiency in the body, due to which the function of the thyroid gland is normalized. Treats Basedow’s disease, endemic goiter and hyperthyroidism [2].
Interestingly, in the Far East, dry kelp is added to the dough for baking bread, based on the calculation of 0,4 mg of powder per 1 kg of flour.
In addition, sea ginseng replenishes iron stores in the body, eliminating signs of anemia.
- Removes bad cholesterol, participates in hematopoiesis, regulates blood pressure, improves memory.
- Strengthens the immune system, nourishes the brain.

Interestingly, with the regular use of seaweed, the likelihood of developing breast cancer in women is reduced by 60%.
Brown kelp contains fucoidan, which has blood-thinning properties. It is used in water procedures to eliminate rheumatism, cellulite and obesity.
Chemical composition
After extracting kelp from the depths of the sea, it is subjected to heat treatment and drying, since it consists of more than 85% water. However, these manipulations do not deprive it of its nutritional value. Despite the partial loss of moisture, vitamins and mineral compounds in sea kale are completely preserved.
The chemical composition of the product directly depends on the illumination, water temperature and sea salinity.
The calorie content of fresh seaweed is minimal and amounts to 10-25 kcal per 100 g.
The composition of polysaccharides is dominated by pectins – alginates (75% of the daily norm in 100 g) and only a small amount falls on starch and sucrose (less than 0,5%) [4].
100 g of the product contains 88 g of water, 3 g of carbohydrates, 2,5 g of organic acids, 0,9 g of proteins, 0,6 g of dietary fiber and 0,2 g of fat [5].
Laminaria is able to accumulate toxic compounds: strontium, arsenic and cadmium.

Beware, laminaria
First of all, the potential harm, it would seem, of such a useful product is due to the environment in which it grows. Algae is able to absorb substances from the environment. In ecologically polluted areas, sea water may contain traces of radioactive elements, oil and heavy metals. In the process of growth, kelp absorbs these substances that are hazardous to human health and causes intoxication of the body, which neutralizes its beneficial properties. [7].
Sea ginseng, grown artificially, is high in iodine, therefore it is dangerous for people with hyperthyroidism.
Contraindications:
- diseases of the digestive system in the acute phase;
- high sensitivity to iodides;
- tendency to food allergies;
- age of 3 years;
- disruption of the endocrine system;
- hemorrhagic diathesis;
- kidney disease;
- acne, furunculosis.
Caution should be exercised by lactating, pregnant women so as not to cause pathology in the fetus. Laminaria is oversaturated with iodine, which, penetrating the placenta, in excessive amounts can lead to abnormal development of the child.
How to use
Dry seaweed is used as a seasoning for baked fish and first courses. It enhances their taste and gives the food a characteristic marine flavor. In addition, dry kelp can be consumed fresh, boiled. To do this, the algae is pre-soaked in water for 12 hours. During this time, it swells and becomes usable. In this form, seaweed is added to salads.
Currently, kelp sheets are becoming increasingly popular, used for cooking Japanese cuisine – sushi.
Today, there are more than 300 culinary recipes using this medicinal plant to maintain good health and fortify the body.
Seaweed is combined with many foods: rice, pasta, cheese, meat, fish, mushrooms and vegetables. This is a universal raw material for the production of original desserts (sweet pies, jams) and snack cakes. Laminaria is fried with potatoes, dried, marinated and served with any dishes: cereals, vegetables, meat or fish.
Enjoying a seafood delicacy, you should follow the norm, which is 100 g of the product per day. This amount is sufficient to cover the body’s need for iodine and pantothenic acid. The latter, in turn, stimulates the work of the adrenal glands, which are responsible for the production of adrenaline. This means that there will be no trace of apathy, blues and depression.

body wraps
The main purpose of the procedure is to improve the condition of the skin (increasing the elasticity of the dermis, giving it a smooth and radiant appearance, eliminating cellulite, stretch marks) [10]. Wraps with kelp activate biochemical processes and increase blood circulation in fatty tissues. As a result, the skin on problem areas (buttocks, abdomen, hips, waist) is smoothed and tightened. Before performing the procedure, the skin is cleaned with a scrub.
Instructions for use:
- Laminaria powder (160 g) is dissolved in 5 liters of hot water (60 degrees). This amount is enough to treat the whole body. The paste is thoroughly stirred for 2 minutes until a homogeneous consistency is obtained.
- For active weight loss, a warm composition of kelp is applied to problem areas 20 minutes after preparation.
If the main purpose of the procedure is to fortify the epidermis or increase skin tone, the paste is pre-cooled for 1 hour, and only after that it is distributed over the body.
- After applying the product to the skin, the areas are wrapped with cling film and left for 50 minutes, then washed off with water. The dermis is not wiped with a towel.
