 Many centuries, seaweed is used not only in food but also for medicinal purposes. In China and Japan algae included in the diet as early as the VIII century, the first recipes for their preparation come down to us from there. Obviously, at the same time began to use aquatic plants in coastal areas of France, Ireland, Scotland and Norway. And in modern times, when humanity strives to improve the quality of life through healthy eating, products based on seaweed is very popular!
Of what, what does, what does ...
Seaweeds contain many substances that have a high diverse biological activity. For this unique composition, such as brown seaweed called laminaria
"Factory of health"
. Polyunsaturated fatty acids, polysaccharides, amino acids, alginic acid, vitamins and their precursors (A, C, D, B1, B2, B3, B6, B12, E, R, PP), enzymes, plant hormones, minerals (K, Na, Ca, Mg, I, Cl, S, Si) - that's only a partial list of active substances, each of which is worthy of attention.
All algae are characterized by high content of large amounts of minerals due to the ability to concentrate sea salt. They contain vitamins C and E and beta-carotene (a precursor of vitamin A) resist the action of free radicals that provoke aging and the occurrence of many diseases. Vitamins and special help enzymes possessing antiradical activity. In the fight against free radicals algae - just the champions!
In the algae more than in all other marine products, certain vitamins, minerals and iodine. Another interesting fact is that the qualitative and quantitative content of macro- and microelements in them resembles the composition of human blood that allows us to consider them as a balanced source of organism essential substances.
Modern medicine classifies algae into groups according to their color:
green, brown, blue-green and green-red algae
. Mainly used kelp
Laminaria and fucus
.
Kelp
stimulating effect on the general metabolism processes, as well as some endocrine glands. Due to the high iodine content, it is used in the treatment of thyroid deficiency. Kelp can normalize the mineral balance, has a reducing effect, promotes the synthesis of vitamin E (tocopherol). The 30 g of dried kelp, dissolved in a water bath is contained more than usual sea water: iodine - 2 times, zinc - 3 times, manganese - 27 times, iron - 18 times.
In Russia, produces two types of kelp:
sugary
Which grows in the northern coast of Russia, and
Japanese
Collected from the Far East coast. In nature, there are about 30 species of laminaria algae. Most - 25 species - inhabit the waters of the northern hemisphere, 3 - in the seas of the Southern Hemisphere, 2 - off the coast of Brazil.
Bladder
It stimulates the blood circulation and cause vasodilation, normalizes renal blood flow, a diuretic effect and facilitates the rapid removal of toxic substances from the body. Bladder active components stimulate the synthesis of vitamin D and sex hormones. This algae contains all the trace elements necessary for the treatment of musculoskeletal apparatus and disorders of mineral metabolism.
Less commonly used in cosmetics and medicine kelp
askofilla
. Its active ingredients have a protective effect on the skin and have antibacterial properties.
Extracts of algae, algae themselves, their individual components have marked a pronounced
anti-inflammatory, immunostimulating, antiradical and prophylactic anti-tumor activity
.
Interesting fact: in algae no roots, all necessary for the life of the substance they receive from the environment, that is, from sea water. Once out of the sea, they would perish, but have a powerful protective mechanism against drying out - in the composition of kelp contains
alginic acid
. They have an amazing ability to retain water. Alginic acid is contained in an amount of 13-54% depending on the type of algae growing location, speed and water illumination. The maximum content of alginates Far East from algae - in August and September, while the northern species - Spring and fall.
Salts of alginic acid - alginates, potassium, sodium, magnesium and calcium - are good "sinks", well this is manifested with respect to the salts of heavy metals and radionuclides, as confirmed by studies Scientists in Japan, Russia and Norway. In the experiments, the absorption of radioactive particles was 90%!
Health, Beauty and cooking ...
Various substances seaweed used in medical, cosmetic and food industry. Algae are collected on the sea bottom, quickly frozen and then dried and pulverized by a special technology. The result is a powder which is ready for use.
In medicine is applied humectants and hemostatic properties of alginic acid - in production styptic as wipes, sponges, gauze, Special wool; low allergenicity, and interoperability - in production drugs. The properties of the individual components of algae, such as mannitol, are used in the manufacture of medicaments diuretic action.
In cosmetology used directly themselves algae for various cosmetic procedures, such as body wraps. Concentrated extracts or individual components of seaweed are part of the creams, serums and masks for face and body. This increases the immunity of skin cosmetics, provides deep moisturizing, has low allergenicity.
In the food industry alginic acid used in the preparation of coffee, cocoa, cream and bread as a filler and a disintegrant. Algae are often entered into the drugs for weight loss because of its ability to swell: there is a mechanical increase in the volume of gastric contents, resulting in a feeling of hunger disappears. All the nutrients contained in algae, further stimulate the immune system and metabolism.
